Tyco Offers Sigma-Link Copper-Cabling Solutions

Sigma-Link from Tyco Electronics's Amp Netconnect business unit is a range of pre-terminated high-speed copper-cabling solutions designed for ease of installation in office networks and data centres. The Amp Netconnect Sigma-Link system offers all performance and link classes including Category 6/Class E, Category 6A/Class EA and Category 7A/Class FA to support current applications at speeds of up to 10Gbit/s over copper cable.

The Class FA version has been developed to support future applications at up to 40Gbit/s. The system is fully standards compliant and is suitable for equipment cabling in data centres. Performance of the Sigma-Link system is ensured by factory testing of all cable assemblies. Traceability of the far end is achieved by an integrated plastic optical fibre, which facilitates identification after installation. The system is fully compliant to TIA/EIA 942 and EN 50173-5, which are specific data-centre standards.

The Sigma-Link system, which forms part of the Amp Hi-D (high-density) cabling platform, is based on a modular approach featuring reusable cassettes and cables. The 10Gbit/s performance over copper is achieved without any requirement for ANEXT testing or EMC considerations. In use, the system provides rapid installation of six connectors with just one click. Cables are pre-terminated at the factory to the correct length with a 'one-click' snap-in cassette and the user simply has to place or pull the cables into the pathways, plug the cassettes into the patch panels and mount the finished patch panel. The Amp Netconnect Sigma-Link system is suitable for partial-section cabling in data centres in areas such as server-to-switch cabling.

NI Announces PXI Express-Based Test Instruments

National Instruments has introduced two 32-channel PXI Express-based digital instruments and an eight-slot high-bandwidth PXI Express 3U chassis for advanced automated test applications. The NI PXIe-6544/45 selectable-voltage digital waveform generator/analysers optimise test applications by supporting clock rates of up to 100 and 200MHz, respectively. The NI PXIe-6545 provides typical streaming rates of 660MB/s. The digital instruments are designed to enable test engineers to conduct sophisticated analysis of high-speed semiconductor devices and high-definition (HD) multimedia components that require rapid transfers of large amounts of data to and from host memory.

The NI PXIe-1082 chassis, a 3U eight-slot PXI Express chassis with seven PXI Express peripheral slots, complements the generator/analysers with up to 1GB/s per-slot bandwidth and up to 4GB/s of total system bandwidth. Because of the advanced operation of the NI PXIe-6544/45 modules, engineers can now automatically test faster semiconductor devices, such as analogue-to-digital converters (ADCs), digital-to-analogue converters (DACs), memory devices, ASICs and microcontrollers. Testing a 200MS/s DAC, for example, previously required a high-speed pattern generator, an oscilloscope and a power supply.

With the NI PXIe-6545 generator/analyser and NI PXIe-1082 chassis, engineers can perform characterisation and production tests using compact, software-defined modular instrumentation. This approach provides greater flexibility by making it possible for engineers to programmatically select voltages of 1.2, 1.5, 1.8, 2.5 or 3.3V; independently configure each of the 32 channels for input or output; and use the high-resolution onboard clock for sub-hertz frequency selection. The data throughput capabilities of the high-speed PXI Express digital instruments and high-bandwidth chassis are suitable for testing many multimedia devices as well, including HDTV signals up to 1080p at 60Hz, LCD screens, RF baseband devices and HD radio.

The NI PXIe-6544/45 modules include enhanced timing and synchronisation features, such as an onboard direct digital synthesis (DDS) clock that provides sub-hertz resolution ranging from DC to 200MHz. This helps engineers clock data generation and acquisition with higher resolution without using an external clock, eliminating the need for an additional high-resolution clocking device and external timing cables. The DDS also helps engineers manage test applications that require arbitrary clock frequencies. Engineers can export the onboard clock to other instruments or import external clocks through the backplane of the NI PXIe-1082 chassis or through an SMB connector on the front panel of the generator/analysers.

With these features, engineers can synchronise the NI PXIe-6544/45 modules with other analogue or digital instruments for maximum correlation of generated signals and measurements across devices. The NI PXIe-1082 eight-slot high-bandwidth 3U chassis features PCI Express lanes routed to every slot. The chassis provides four hybrid slots that engineers can use for either PXI Express or PXI hybrid-slot-compatible modules to maximise reuse of existing PXI modules. Designed for high-performance systems, the NI PXIe-1082 chassis offers an operating temperature range of 0 to 50C and provides integrated system monitoring features, including power management, fan health and temperature monitoring, for the entire chassis.

DC/DC LED Drivers Launched By Powerpax UK

Powerpax UK has announced the launch of the PLC24AH range of dimmable, constant current, DC/DC LED drivers. The PLC24AH series provide a step-down constant current source for driving high-brightness LEDs. Standard output currents include 300mA, 350mA, 500mA, 600mA and 700mA, making these drivers compatible with a range of LEDs and applications. The output voltage range for these drivers is 2-32VDC and all models feature continuous short-circuit protection. These products have a compact size and operate without the need for external components.

They provide a high-efficiency solution (up to 95 per cent) for LED driving in both standard and dimming applications. Dimming is achieved through use of an industry standard PWM method - the PWM input is specified to operate between 0.2-10Khz. If dimming is not required, the PWM input doubles as a remote On/Off input. This series has an operating temperature range of -40C to +71C (minimum). These drivers are compact and feature a case size of 22.8 x 10.2 x 9.5mm with a weight of 3.5g.

The case is manufactured from a UL94-V0 rated plastic and these parts conform to RoHS requirements. The series is designed to be as reliable as the LEDs it will drive, and the MTBF for these drivers is two million hours (calculated to MIL-HDBK-217F at 25C). In addition to this range of DC/DC LED drivers, Powerpax also offers a range of AC/DC LED drivers, including standard dimming and waterproof driver products.
Mazet Introduces Multi-Range Spectral Sensors

Mazet has unveiled its multi-range spectral sensors that it uses as a basis for developing and supplying application-specific sensor modules for its customers. The sensors can be adapted to applications with regard to the number of spectral channels and the spectral transmission characteristics of each channel. The first sensor introduced in this design has six spectral channels, whose filters, which range from 400nm to 700nm, overlap one another and are uniformly distributed over the range.

These modules are distinguished by their small size, their parallel signal processing of all spectral channels, their high operating temperature range, their long-term stability and their high degree of resistance to environmental effects. In cooperation with Jenoptik, customised optoelectronic modules are offered in a compact design.

These modules include all of the system components, from the optics to the electronic signal processing. These sensor modules are predominantly used in areas where spectrometers are unable to cope when it comes to size, price or signal processing speed. These can be micro-fluid sensors, handheld devices for qualitative analysis or basic process sensors.
DC/DC Converter Launched By Ericsson

Ericsson Power Modules's BMR454 DC/DC converter delivers double the power of most conventional eighth-brick modules, a wide input range of 36-75V, and a tightly regulated output. The BMR454 eighth-brick family delivers up to 240W with an efficiency rating up to 95 per cent at full load, and a PMBus interface is included. The parameters of the BMR454 can be monitored via PMBus, and they can also be adjusted - by the customer or Ericsson - into an endless number of combinations.

The module can be used as an intermediate bus converter (IBC) in front of a range of regulators, or as a traditional DC/DC module powering applications such as hard drives, fans and others. Important application areas are 48V information and communication technology applications such as radio base stations, servers, routers, and a range of systems powered by 48VDC. The modules can be used for improved system efficiency, as output voltage and other parameters can be adjusted online to improve efficiency at specified load conditions.

Additionally, vital parameters such as input voltage, output voltage, output current and temperature can be monitored online. The module's output voltage can be adjusted between 8.1V-13.2V with a tight output tolerance of +/- 2 per cent. Offering a power density figure of more than 18W/cm2 (117W/in2), the BMR454 is pin-compatible with its big brother, the BMR453, making it possible for designers to upgrade to higher power when upgrading boards with new functionalities.

The module has a high efficiency figure of typically 95 per cent at 53V input and 12V output at full load of 20A. The module also offers high efficiency from light-load to full-load conditions as a result of its flattened power curve. For safety and reliability, the BMR454 features a 1,500VDC input to output isolation figure.

The modules are also offered without the PMBus connector, providing exactly the same footprint as a traditional IBC. In such a configuration, the customer still has the benefits offered by the built-in digital controller, and high efficiency across the complete range of operation. Factors driving the demand for this type of product are system flexibility, improved control and monitoring, high power density (240W/eightbrick size), and the need for good thermal derating. By using PMBus, the module can be configured in a virtually endless number of combinations.

Almost all electrical parameters can be changed to exactly meet the customer's needs. Output power delivered to the load is easily monitored through PMBus, making it easier for systems architects to monitor power consumption. Improving time-to-market and time-to-customer, the module's configuration flexibility is the key. A new configuration is easy to download and can be implemented both at the customer's site and in a manufacturing plant. The electrical design is based on a full-bridge topology into a centre-tapped half-bridge topology.

Both transformer and output inductor are integrated into the PCB, which combined with the selection of low thermal impedance MOSFETs provides a good thermal performance. Besides the high level electrical and thermal performances inherent in its original design, the combination of a built-in digital controller and PMBus interface position the BMR454 as suitable products for systems integrators when considering forthcoming regulations. The BMR4540100/002 is rated at 9V/20A, the BMR4540000/001 is rated at 12V/20A and finally, the BMR4540001/001 is also rated at 12V/20A, but supplied without a digital interface.
GPS Simulation Toolkit 1.5 For Labview

National Instruments (NI) has announced the NI GPS Simulation Toolkit 1.5 for Labview. This is an extension of the graphical system design environment that expands the NI RFP XI platform to provide engineers a cost-efficient, high-performance solution for GPS receiver testing. The latest version of the GPS Simulation Toolkit gives engineers new satellite simulation features including extended time duration of non-repeating GPS satellite signals and the ability to customise motion profiles for mobile receiver tests.

The GPS Simulation Toolkit 1.5 for Labview offers engineers an easy-to-use graphical API for validating and testing GPS receivers. Using the toolkit, engineers can simulate C/A codes for up to 12 satellites in the L1 band. The toolkit also features waveform creation tools to specify both the receiver location and velocity, and the ability to create waveforms with up to 24 hours of non-repeating GPS satellite signals, giving engineers a longer period of non-repeating simulation data than other GPS test solutions.

This makes it possible for engineers to achieve extended reliability testing and superior control over signal impairments introduced during design verification testing. The latest version of the toolkit also adds new capabilities for generating custom motion trajectories, so engineers can simulate the signals that GPS receivers capture on specific routes. The ability to simulate these signals using software-defined instrumentation helps engineers conduct customised and repeatable tests featuring route-specific signals without performing expensive drive tests.

Additionally, with the GPS Simulation Toolkit, engineers can adjust individual satellite signal powers during signal generation for dynamic range and scenario-specific tests. The NI RF PXI platform for GPS simulation and test includes the GPS Simulation Toolkit 1.5 for Labview, NI PXIe-5672/73 vector signal generator, NI 8260 in-chassis RAID hard drive, NI PXIe-8106 dual-core controller and NI PXIe-1062Q eight-slot chassis. Engineers can store up to 45 hours of simulated GPS signals on the 1 TB NI 8260 in-chassis RAID hard drive and stream the GPS waveforms from disk using the NI PXIe-5672/73 vector signal generators for customised and repeatable GPS receiver testing.
Analog Converters Used In Large Hadron Collider

Analog Devices' data converters are helping scientists discover what the universe is made of and how it works by playing an important role in Cern's Large Hadron Collider (LHC). Hans Rykaczewski, resource manager at Cern, said: 'The converters we use need to be radiation-hard and reliable because they must function properly for decades in a high-radiation environment.

'The collisions created by the LHC emit energy that can be measured and analysed once it is converted to a digital data stream. 'Analog Devices' converters have the speed and dynamic range we need to measure the energy captured by one of the 64,000-lead tungstate crystals. 'These crystals measure the energy of photons, electrons and positrons.' Within the LHC, two beams of subatomic particles called 'hadrons' - either protons or lead ions - will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to collide the two beams head-on at very high energy.

Teams of physicists from around the world will analyse the particles created in the collisions using special detectors. Cern selected Analog Devices' AD9042 high-speed, low-power, 12-bit ADC (analogue-to-digital converter) for use in its detectors. Data converters are the key components that translate real-world phenomena, such as light, sound, temperature, motion and pressure into electrical signals used in an array of electronic equipment.
DC/DC Converter For GSM And GPRS Cards

Linear Technology has announced the LTC3125, a 1.6MHz current mode, synchronous boost DC/DC converter with an accurate and programmable average input current limit. Its internal 1.2A switches can deliver output voltages as high as 5.25V from an input voltage range of 1.8V to 5.5V, making it ideal for Li-ion/polymer, 3.3V PC card slot or multi-cell alkaline/Nimh applications.

The LTC3125 can deliver up to 500mA of continuous output current (at 5V) from a 3.3V input. The LTC3125's average input current limit can be programmed between 200mA and 1000mA with +/- 5 per cent accuracy. The accurate adjustable current limit combined with an output reservoir capacitor makes the LTC3125 ideal for applications such as GSM and GPRS cards, which demand 2A or higher current pulses from a power-limited input source. In addition, the LTC3125's accurate input current enables safe and fast charging of large super- or ultra-capacitors in battery backup systems without overstressing the battery or auxiliary power source.

Synchronous rectification enables efficiencies up to 93 per cent while burst mode operation lowers quiescent current to only 15uA, providing extended battery runtime in handheld applications. The LTC3125 can also operate in Buck mode, providing a regulated output lower than the input. The combination of a 2 x 3mm DFN-8 package and a constant switching frequency of 1.6MHz minimise both inductor and capacitor sizes, providing the small footprint and profile required by PC-card applications. Additional features include short-circuit protection, soft-start, and thermal protection. LTC3125EDCB is available from stock in an eight-lead 2 x 3mm DFN package.
Adlink Bases Coremodule 730 On Intel Atoms

Adlink Technology has introduced the Coremodule 730 embedded processor, based on the ultra low power Intel Atom Z510 and Z530 processors at 1.1 and 1.6GHz, respectively. The Coremodule 730 sets a new efficiency standard for tiny rugged computers by using the new Sumit expansion interface.

It reinvents stackable and mezzanine architectures by packing an enormous amount of data bandwidth and easy connectivity - including multiple PCI Express lanes, USB 2.0 interfaces, LPC bus, I2C bus, and SPI bus - into a fraction of the space previously occupied by only the 33MHz parallel PCI-104 bus. The Coremodule 730 features PCI Express, Gbit Ethernet, USB 2.0 ports and a Compactflash socket.

It also features the lowest power Intel chipset available, the US15W, to complement the Intel Atom processor for a total power consumption of only 5W. Conductive cooling solutions are also easy to implement for small sealed boxes with no internal air flow. The release of the Coremodule 730 means that system OEMs in military, avionics, transportation, data logging, portable computing and other rugged markets can add an Intel Architecture controller to their systems without a custom carrier-board design.

Sharp Announces High Colour Rendering LEDs

Sharp is expanding its LED portfolio with eight white light high colour rendering SMD LEDs in the frequently used PLCC2 package. The high CRI (colour rendering index ) value of 80 is reached by a combination of a blue LED die covered with a special mixture of green and red phosphor. The chip LEDs of the GM5SAExxP0A series, from the E-Series, ensure natural colours and true to detail images.

This is important where artificial light may not hinder the depiction of the illuminated objects. Typical applications for high colour rendering (HCR) LEDs are in photography, shop windows and store decorations as well as product presentation. They also find uses in medical lighting; for example, in surgery lamps. The E-Series covers a wide spectrum of colour temperatures, beginning with warm white LEDs in the area of 2,700K to the cold white LEDs of 6,500K.

Combining high CRI values and a light efficiency of up to 90lm/W (depending on model), the HCR LEDs from Sharp show characteristics equal to traditional fluorescent lamps in terms of efficiency, colour temperature and CRI. The E-Series complies with the requirements of the international energy star programme. Due to this, the LEDs of the GM5SAExxP0A series are suitable for next-generation LED lighting applications as well as occasions where fluorescent lamps are traditionally used.

The E-Series is characterised by an extreme long lifetime of 40.000 hours of operation. The chip LEDs of the E-Series are equipped with a Zener diode, integrated directly in the package. They protect the LED against voltage peaks that may occur through electrostatic charge. This will spare developers the integration of additional ESD components on an external circuit.

Despite the high integration level, the E-Series is marked by an extremely compact and slim housing. The package of 3.2mm x 2.8mm x 1.9mm (PLCC2) makes this high colour rendering LED series from Sharp a suitable fit for applications that require a high amount of brightness with a compact form factor. This HCR LED series from Sharp is designed to give lighting designers more freedom and flexibility when creating illumination systems, which are not necessarily determined by the form factor of the illuminant.

The P78 series features regulators with outputs of 0.5A and 1A, with efficiencies of up to 96 per cent.

They feature inputs in the range of 4.5VDC to 32VDC and have low no-load current, making these products suitable for many applications, including those with battery power sources. All products have low-output ripple and noise and have comprehensive inbuilt protection, including continuous short-circuit and over-temperature protection. Output voltages range from 3.3V to 15V with a maximum line regulation of +/-0.4 per cent and a maximum load regulation of +/-0.6 per cent.

In addition to the standard positive output voltages, it is possible to configure these devices to provide negative output voltages. These regulators are available in two package styles with standard TO-220 three-pin and SMD variants. Both case styles are provided in a plastic package, which is UL94-V0 rated and RoHS compliant. The SMD versions of these products provide extended features with output-voltage adjustment and remote on/off, in addition to the standard features of the three-pin SIL versions.

The high-efficiency design of this series (8.5W/CM3) means that internal losses are kept to a minimum and, as a result, no heat sink is required. This makes application easier as the designer does not need to be concerned with the thermal issues often associated with the use of linear regulators, according to the company. The operating temperature range is -40C to +85C with free air convection cooling. These Powerpax high-efficiency regulators have a typical MTBF greater than two million hours calculated using MIL-HDBK-217F.
Goepel Develops Juliett Family Of JTAG Testers

Goepel Electronic has announced the development of Juliett (JTAG unlimited tester): a family of completely integrated standalone production testers. The modular systems combine all test electronics and the basic mechanics in a compact desktop system. Additionally, they are equipped with a specific interface to an exchangeable adaptor, giving fast changes to accommodate different units under test (UUTs). Thomas Wenzel, director of the boundary scan division at Goepel Electronic, said: 'The increased use of extended boundary scan techniques has led to the need for a completely integrated production system.

'Due to the use of the preset Juliett tester, time-consuming integrations for cost-intensive special solutions can be saved and the handling becomes all in all more effective. 'At the same time, with this system, we become the first vendor to provide off-the-shelf products for turnkey solutions,' he added. Designed as commercial off-the-shelf (COTS) products, the desktop systems are available in Juliett-Base or Juliett-Standard versions, with differences in the number of available input/output (I/O) channels (120/240) and TAPs (two/four), as well as in the scan performance (16MHz/50MHz).

All Juliett systems provide four independently programmable UUT voltages, including current measurement for two and four registers for covering gang applications and an effective adaptation area of 310mm x 210mm. An integrated exchangeable-adaptor appliance with type recognition allows standard UUT adaptations over needle contacts or real connectors with simultaneous access to all interface signals, even in the active state. Due to this, the selective monitoring of critical signals is facilitated and the debugging becomes more effective. Based on this, a broad use of the systems in various markets and applications is possible.

In principle, all Juliett systems allow the execution of boundary scan tests, the in-system programming (ISP) of Flash and PLD, functional emulation tests, MCU programming and interface tests, with the active process being visualised on an integrated display. The control of the complete process is carried out by an external USB or local-area-network (LAN)-connected PC or laptop, using more control elements integrated in the system. The software consists of standard versions of the System Cascont JTAG/boundary scan program package; as a result, laboratory test programs can be continuously used.

Regarding the hardware, Juliett-Standard offers the performance and upgradeability of the ScanflexR architecture, while Juliett-Base is based on the low-cost ScanboosterT architecture. Both Juliett versions are available in runtime station (RTS), failure diagnostics station (FDS) and repair/debug station (RDS) configurations. The latter provides all ScanassistT debug tools, as well as ScanvisionT for the graphical visualisation of detected faults. The Juliett systems are available worldwide as a standard product. Adaptations can be carried out by Goepel Electronic, by authorised test houses or by the customer on the basis of draft adaptors. Delivery of the Juliett systems will start in June 2009.
LDMOS Transistors Aid Design Of Wireless Stations

Infineon Technologies AG has introduced a range of high-power LDMOS transistors for the design of broadband wireless-network base stations. The transistors, introduced at the IEEE MTT-S International Microwave Symposium, feature power levels up to 300W and video-bandwidth exceeding 90MHz. They support the high peak-to-average power ratios and high data-rate specifications required for the evolution from 3 to 4G wireless networks.

The new transistor range achieves higher gain and higher power-density than alternative devices operating in the 1.4 - 2.6GHz cellular bands. This allows the use of packages with a 30 per cent smaller footprint, to enable smaller and lower cost amplifier designs. High peak-power is valuable for Doherty-based amplifier designs, as well as for reducing parts count in other architectures. Illustrative performance of the new transistors, in a two-carrier WCDMA signal at 2170 MHz, 30V, 8dB PAR and 3.84MHz channel bandwidth, is: 50W average power, 18dB gain and 28 per cent efficiency (using a transistor with P-1dB output power of 230W).

A 300W (P-1dB) device in the same application measures 65W average power, 18dB gain and 28 per cent efficiency. All the new PTFB transistors are offered in open-cavity ceramic packages for bolt-down or earless mounting. They are Pb-free and ROHS compliant. Samples of the first six products are now available.

Intersil Unveils Flexible ISL54230 Octal Switch

Intersil has introduced the ISL54230 Octal switch, which is suitable for high-end Smartphone applications. The ISL54230's small size and flexible design enable designers to optimise the routing of the many different types of signals in dual-mode, dual-standby operation phones. It is a quad double-pole/double-throw (DPDT) analogue switch that can operate from a single +2.0V to +5.5V supply.

It contains eight single-pole/double-throw (SPDT) switches configured into four DPDT blocks. Each DPDT block is independently controlled by a logic input signal. This flexible configurability provides switching and routing of USB, UART, PCM for Bluetooth Phy, SIM power/data and audio signals between internal chips and external connector pins.

In particular, the ISL54230 allows dual-baseband chips to access either of two SIM cards while allowing the unused SIM card to be powered down into a zero-power-consumption condition. Dual USB 2.0 high-speed 2:1 multiplexers provide USB connector access to multiple baseband and multimedia processor chips. To enable SIM card supply line switching, the ISL54230 includes a pair of 1ohm switches.

SP 2 Supports ECP3-70 And ECP-95 Devices

Lattice Semiconductor has introduced Service Pack 2 for Version 7.2 of its Isplever FPGA design-tool suite. SP2 is an important update for users of LatticeECP3 devices and also includes support for new LatticeXP2 devices. Mike Kendrick, manager of software-product planning at Lattice, said: 'This important update allows users of ECP3-70 and ECP-95 devices to design with even greater confidence that the board-level behaviour of their design, such as simultaneous-switching output noise (SSO), power and timing, will match what the tools report.

'SP2 also boosts DSP application performance in the LatticeECP3 devices.' Design support for the LatticeECP3 FPGA range was first made available in the Isplever 7.2 SP1 design tool suite. Service Pack 2 updates the device values to production-characterised silicon for the LatticeECP3-70 and ECP3-95 devices. With SP2, static timing analysis, power and SSO will report results that more accurately reflect the behaviour of the actual production device.

PCS/Serdes calibration settings used for the supported IO protocols have been tuned to provide more robust behaviour. The SysDSP block support has been enhanced to include higher performance modes of primitive blocks targeted at specific applications, such as FIR filters, decimators, interpolators, matrix multiplication and video applications. These modes are made possible by the enhanced cascade support in the LatticeECP3 devices' SysDSP architecture. Service Pack 2 also supports the industrial temperature qualified, non-volatile LatticeXP2 devices that are available now in low-cost, small-footprint BGA or QFP packaging.

The Isplever design-tool suite provides a set of powerful tools for all design tasks, including project management, IP integration, design planning, place and route, in-system logic analysis and more. The Isplever tool suite is provided on CD-ROM and DVD for Windows, Unix or Linux platforms. Synopsys' Synplify Pro advanced FPGA synthesis is included for all operating systems supported, and Aldec's Active-HDL Lattice Edition simulator is included for Windows. In addition to the tool support for Lattice devices provided by the OEM versions of Synplify Pro and Active-HDL, which are included in the Isplever tool suite, Lattice devices are also supported by the full versions of Synopsys Synplify Pro and Aldec Active-HDL.

Mentor Graphics Modelsim SE and Precision RTL synthesis also support the latest Lattice devices, such as the LatticeECP3 family. Precision RTL synthesis support for LatticeECP3 devices requires an update available from the Mentor Graphics website. The Isplever 7.2 Service Pack 2 tool suite for Windows, Linux and Unix users is available immediately without charge for customers with active design-tool maintenance contracts.

Micro Metalsmiths Makes Fuel Cap For Spyker

Micro Metalsmiths has developed and manufactured a specialist fuel cap for Dutch luxury car manufacturer, Spyker. The fuel cap, which features Spyker's company emblem, took less than eight weeks to deliver and will feature on all production cars.

Micro Metalsmiths had to quickly re-engineer the production tool, which was completed in only two weeks. This needed to be more economical and less complex to machine, while providing an aesthetically pleasing appearance.
Reel And Shaft Offers Stacker Truck Cradle

Reel And Shaft Handling (RaSHCo) has designed a stacker truck cradle for offloading finished reels from both shafts of slitter rewinders at the same time. The system is easy to install and operate and is safer and faster than traditional methods. The stacker truck cradle slides easily into place under the finished product reels, then gently pulls them from the shafts as the operator reverses the truck.

The hydraulically powered cradle then rotates the reels to vertical so they are ready for loading onto a pallet. A separate vertical reel lifter mounted on a customised air hoist, hanging from a swing-jib crane, allows the operators to offload the reels of up to 95kg, quickly and with virtually no effort.
Active Andon System Reduces Downtime

A user-programmable LCD display shows whatever data is required, and can be changed at any time. Off-the-shelf delivery of LCD displays of all sizes means no long waits for equipment to arrive.

If there is a problem, messages and alerts are displayed on the Andon board, and it is automatically escalated to senior staff via email or text. Alerts based on any aspect of the production process are automatically triggered. A closed-loop process ensures problems are resolved quickly and effectively, so that downtime and maintenance stoppages are minimised.

All data is available for review and analysis on a PC. The wireless system allows the user to put button boxes in any location; supervisors can move around the shop floor and take a button box with them. Minimal cabling means minimal cost to install.
JP Forrest Invests In More Boring Capacity

JP Forrest of Worksop, Nottinghamshire, UK has ordered a large five-axis horizontal boring machine from Italian manufacturer Alesa Monti. The machine, which is due to be commissioned in July this year, has a table size of 2500mm x 2000mm, X-axis travel of 4000mm and Y-axis travel of 3000mm, with Heidenhain ITNC 530 five-axis control.

Managing director Martin Hodgkinson says: 'This machine is the central part of a GBP1m expansion project, which includes the building of an extension to the company's premises, almost doubling the effective floor area of the existing machine shop.' The expansion plans also include the installation of a 20-tonne overhead crane in the machine shop extension.

The company, which specialises in the fabrication and horizontal boring of equipment such as gear cases, housings and mainframes, already has six horizontal borers working on two shifts, but recent requests from several key clients for heavier components has led to the strategic decision to invest in a heavy fabrication and machining capability. JP Forrest is exhibiting at Subcon on Stand C117.

ABB has launched the latest version of its six-step energy saving plan. It provides customers with information on the best ways to save money, by applying variable- speed drives and low-voltage motors to their fan and pump applications. The six-step energy saving plan is captured in a free 20-page guide, available to download. Using the guide, customers can assess up-to-date information on climate change and how it could affect their business.

The guide also provides information on how to save money in setting up and running drive and motor applications, with tips on managing installations and when best to replace old technology with modern drives and motors. Schemes to help those willing to invest are also highlighted in the guide. The government's Enhanced Capital Allowances (ECAs) scheme, and interest-free loans from the Carbon Trust help reduce the initial cost of implementing energy saving measures.

ABB's six-step plan provides information on what they are, qualifying requirements and information on the savings that are available. The updated guide provides numerous examples of companies that have benefited from implementing energy saving drives and motors in their production or process. A number of web links point to further information and advice useful to those looking to implement energy savings measures.
Proto Labs Lowers Entry-Level Prices

Proto Labs has announced that it can now make a mould and ship injection-moulded parts for as little as GBP995. The company attributes its price reduction to increased efficiencies in its automated manufacturing processes, improvements in its software and advances in its application of compute cluster technology.
Stahl Releases Fieldbus Power Supply System

Stahl has expanded the ISbus range, adding a modular Fieldbus power supply system that provides up to 28V and 500mA for Foundation Fieldbus H1 segments, and allows for redundant supply. In Boost mode, a parallel connection of two power supplies enables users to continuously supply the bus with up to 1A, providing sufficient power reserves even for special Fieldbus applications.

An integrated basic diagnosis function monitors each segment for line faults, reporting these via a potential-free relay contact and indicating them via a red Error LED. The activation of the integrated switchable Fieldbus terminator is clearly indicated by a yellow LED. The units can be installed on a DIN rail or clicked into place on special bus carriers. On each bus carrier, up to eight segments with a standard supply or four segments with a redundant supply are connected to a host via optional precon-figured system cables.

The bus carrier can be operated with a redundant auxiliary power supply. It ensures shielded connection of the Fieldbus cables via large-scale terminals. The terminals also serve as a cable-strain relief. The basic Fieldbus power supply version monitors the bus for cable breaks and short circuits. The advanced Fieldbus power supply, available shortly, provides advanced diagnostic features concerning physical layer parameters, such as signal level, noise, asymmetries and jitter, rendering costly diagnosis modules unnecessary.
Aerospace Industry Buys Flexible Enclosures

Huntingdon Fusion Techniques (HFT) has sold flexible welding enclosures to global aerospace manufacturers involved in helicopter, bellows, spacecraft and fluid handling systems production. The HFT enclosures are manufactured from UV-resistant PVC, and are suitable for welding with oxygen levels down to 10 parts per million.

All enclosures are manufactured as standard with two sets of glove ports, but extra sets can be specified. The upper half of the enclosure is optically clear and provides good welding vision. An entry lock is fitted, for small parts to be taken in and out without loss of purge quality. An exhaust valve allows continuous purging, so that impurities can be expelled during welding.
Dormer Offers Replaceable-Head Drilling Solution

Dormer Tools has added a replaceable-head drilling solution to its programme of solid-carbide tooling. Offering high productivity across a range of materials, the range - branded Hydra - represents a cost-effective alternative to solid-carbide drills. Two head types are available.

The Hydra-M (R960) has been developed to give optimum performance in stainless steel and cast iron, but is also recommended for drilling operations in titanium and nickel. The Hydra-P (R950), meanwhile, is suitable for machining carbon and alloy steels. All drilling heads are manufactured from micrograin carbide and feature a titanium aluminum nitride-based coating for high toughness and oxidation stability, enabling high speeds and feeds while resisting built-up edge.

The self-centring 140-degree four-facet split point means that required thrust forces are low, while the need for pre-drilling is eliminated entirely. Heads are held in place by two screws; ground serrations on the back of the drill head and body tip interlock perfectly, maximising tool rigidity and ensuring even torque transmission for accuracy and precise tolerances, according to the company. Andrew Reynolds, drilling product manager, said: 'One major benefit of the Hydra range is that the heads can be quickly and easily changed without removing the body from the spindle, thus reducing machine downtime.' Available for drilling depths of 3 x diameter (H853), 5 x diameter (H855) and 8 x diameter (H858), drill bodies are made from hardened steel with high-gloss nickel plating for increased resistance to wear and corrosion.

One body can accommodate multiple head sizes with no compromise on structural integrity. The slow spiral offers optimised flute volume, while internal coolant channels ensure smooth chip evacuation. Both Hydra-M and Hydra-P are available in a comprehensive size range (12mm to 30.5mm or 15/32in to 1.3/16in).
DSK Orders Pullmax 720 Punching System

DSK Engineering has placed an order with Pullmax, valued at more than GBP300,000, for a 720 punching system. This comes after a long-term customer told Dave Jordan, managing director of Pontefract-based subcontractor DSK Engineering, that it had plans to put a growth plan in place by the end of June 2009, if not sooner. Jordan decided to make some decisions regarding investment in capital equipment so that DSK could continue providing this customer with good-quality products and services.

DSK is an existing user of laser technology, but it was apparent that the next investment would need to complement laser cutting in order to deal with the range of specifications and materials outlined by its customer. Jordan decided that modern CNC punching technology would provide DSK with the additional dimension required. He contacted Coventry-based Pullmax in March 2009 and, following an initial assessment of the company's requirements, a visit was set up with a local user who has, for a number of years, invested in Pullmax punching technology, most recently in a Pullmax 720.

Research showed that it was possible, with Pullmax, to maximise any investment and extend a machine's capability with a range of add-on features that could be retrofitted to allow a higher level of production, which DSK believed would be required in the future. This included the possibility to add tower stores, load and/or unload automation and extend tooling magazines and part picking options, all of which can be purchased at a later date if workloads increase further. At the time of the visit, the 720 system had worked without any operator intervention for 67 hours non-stop.

For Jordan and his team, meeting the customer's deadline was the most important issue and being able to view a similar application of a Pullmax user illustrated that the Pullmax 720 would be the most productive and flexible punching solution. As a result, an order for a similar system was placed at the end of April. DSK decided that, initially, a standalone machine would allow the company to produce prototypes quickly and still leave the option of automation open for the future. The machine was delivered at the end of May. In order to ensure optimum material utilisation and the rapid programming of parts for the increased workload, a flexible programming system supplied by Radan was also ordered by DSK. The package includes Radpunch, Radan 3D and Equote.

Sprint 300 Plus Improves Quality Of Clean Rooms

Sara Loading Bay Specialists has introduced the Sprint 300 Plus clean room door, which enables pharmaceutical and food companies to improve the quality of clean rooms. The high-speed and flexible configuration of the Sprint 300 Plus - with optional FDA-approved materials - means that it is suitable for areas where there is an air-pressure difference, such as clean rooms. In these environments, the Sprint 300 Plus also saves energy and provides maximum safety provision, with an electrically monitored contact safety beam and a clear safety curtain that allows personnel to see movement on either side, which is essential in facilities that employ automated transport.

Designed to conform to EN 12424, Class 1, for wind resistance, the Sprint 300 Plus is described as a robust, flexible and highly reliable door that provides smooth and steady movement via a curtain tensioning system. It can be programmed to meet specific customer needs using Sara's optional MCC Vector control system. The flexibility of Sprint specification allows the door to suit widths from 1,000mm to 4,000mm and heights from 1,000mm to 4,200mm and delivers a space-saving design that is said to be suitable for areas with restricted head room.

The Sprint 300 Plus offers users the choice of galvanised- or stainless-steel side frames, barrel and motor covers, with bottom rails of anodised aluminium or stainless steel. This choice also extends to materials for the door curtains. The standard is clear PVC with coloured reinforcing stripes, with the options of: PVC with silicon-free reinforcing stripes; Rolltex (with optional windows), which has a sound-reduction quality (Rolltex Plus Fine reduces sound by approximately 17dB); and FDA-approved Nomatex, which is available in yellow and grey with optional vision panels and in a flame-retardant configuration for increased safety applications.

The Sprint 300 Plus door saves energy because of its high-speed operation, with opening speeds of up to 2.2m/s provided from the optional vector control system. It can also be programmed for dual opening heights with the vector control option reduced for normal use - keeping energy losses to a minimum - and full-height opening for occasional larger equipment. The door is equipped with an electrically monitored contact safety edge and integrates a door line stationary photo cell, which automatically stops the door if it senses an obstruction and returns it to its open position.

In addition, drop-down protection is provided by tension springs and there is a built-in facility for emergency self-opening in the event of power failure; this via a Bowden lever brake release. Complementing the range of standard safety features are a number of options. These include: an automatic self-opening feature; the facility for a second Bowden lever brake release; integrated light curtains for doors of more 1,865mm in height; and a knock-out facility option for impact protection with manual reset.
Machine Building Systems Offers Item Base Plate

Item has added a die-cast 'Base Plate 8, 40x40 M10' to its aluminium-profile machine construction kit, available from Machine Building Systems. An M10 foot is suitable for customers with uneven floors who require a knuckle foot with a generous amount of adjustment on a bench or a conveyor, for instance. This gives the longer threads some resistance to the side loads that they will meet.

However, this leads to two problems, according to the company. First, the 40x40 profile most commonly used for legs has a bore at the tapping size for M8 and must be drilled and re-tapped out where this is feasible. Second, permissible thread pitch deviations under DIN standards, common in the male threads, often mean that the feet will bind in long tapped holes, no matter how accurate the tapping.

The new base plate is intended to solve both these problems at low cost by having the M10 tapped hole for the foot aligned with any of the T-slots in the leg. The centre hole is used for securing the plate to the profile with the usual M8 screw.

Micro Metalsmiths Opens Machining Facility

Micro Metalsmiths has launched an advanced, high-efficiency machining facility, based around its recent acquisition of nine CNC Fanuc Robodrill machines. The facility is at Kirkbymoorside, near York, and is one of the company's two production sites in North Yorkshire. The launch event was attended by customers of Micro Metalsmiths, senior representatives of major international equipment suppliers and consultants to the facility. These included Mike Fujita, president and chief executive officer of Fanuc Robodrill Europe, and Mike Berry, general manager of 600 UK, part of machine tools group 600 Group plc.

Guests heard Christopher Shaw, Micro Metalsmiths's chairman and managing director, detail the reasons behind the company's decision to create a dedicated, centralised machining facility - capable of both manned and unmanned machining operations - and to make a major investment in the latest Fanuc Robodrill technology. He said that the present-day marketplace requires even higher degrees of accuracy than could normally be achieved by the company's previous generation of machine tools, which operated at maximum spindle speeds of 10,000rev/min.

This requirement has a direct impact on Micro Metalsmiths's two core business streams: the supply of precision metal components produced from in-house investment castings coupled to high-quality machining; and the design and manufacture of microwave components for the aerospace and telecommunications markets. Shaw said: 'In considering the purchase of new equipment, the company decided to combine the two main machining areas and to look for a type of machine tool that would suit both the short-run requirements to finish off highly accurate castings and the long-run requirements of the latest sophisticated microwave devices, which were requiring cycle times of up to 20 hours on the older equipment.' He added that Micro Metalsmiths started with the view that a 2ft-thick concrete foundation would be needed in the new machine shop to stabilise any ultra-high-speed machines and to prevent them from walking.

Shaw said: 'It came as a very positive surprise to find that this new generation of Fanuc machines needs no such foundations and only the minimum of holding to the floor. 'This comes about due to the sophistication and speed of the latest controllers, which control rates of acceleration and thereby allow for bumpless stops at the end of rapid traverse movements,' he added.
John Neale Creates Water-Based Rust Inhibitor

John Neale has developed Rust Preventive FC-X: a water-based rust inhibitor that has given a 1,000-hour salt-spray performance in independent tests. High-performance long-term outdoor corrosion inhibitors have typically been based on oxidised waxes with other additives in solvents. The solvents used are volatile organic compounds (VOCs), the emissions of which need to be reduced.

The solvents are also often flammable or of low flash point, have exposure limits and can cause skin de-fatting. These products can, however, offer high-performance de-watering and long-term corrosion inhibition. According to the company, there is now a desire for rust preventives to give new performance characteristics. These include: a dry film, which means that dust and dirt will not adhere to it; non-VOC; and renewable or renewable-based.

Rust Preventive FC-X is said to achieve all these requirements. It is a renewable-based inhibitor with negligible VOC content (no added VOC) and a dry film. It dries rapidly and features very high salt-spray corrosion protection. It has protected 'Q' Panel test panels in outdoor tests for 12 months without corrosion. Rust Preventive FC-X has excellent wetting and gives effective de-watering performance, according to John Neale. This product is suitable for companies looking for an alternative to solvent-based long-term corrosion inhibitors.
NMB-Minebea Benefits From Aqua-Save 30 System

A wastewater treatment system from Aqua-Save Technologies, part of Mecwash Systems, is helping a UK manufacturer of aerospace bearings enhance its environmental performance and save processing costs. The use of an Aqua-Save 30 at NMB-Minebea UK's Lincoln factory has helped to address a waste product disposal requirement that results from a key part of its manufacturing processes.

Stuart Haysman, health, safety and environmental officer at the site, said: 'We undertake a wide range of processing operations including machining, plating, grinding and anodising and, in many cases, products pass through a "rumbling" phase - a vibratory process that enhances the surface finish of each product. 'This requires significant amounts of water that, inevitably, become contaminated with oil, metal "fines", detergent and media dust, which, in turn, calls for a suitable disposal process.

'Conventionally, this has seen large volumes removed from site by independent contractors, but this has been dramatically reduced since installing the Aqua-Save,' he added. The Aqua-Save 30 system, which benefits from an integrated pre-heat stage to aid the separation of emulsified oils prior to processing in the main vessel, is housed in its own outbuilding, adjacent to a collection tank that receives water from the manufacturing process at a rate of around 20m3 per month.

The cleaned water, which represents around 95 per cent of the original volume, is of a sufficient quality for the local water authority to permit safe disposal to drain, although NMB-Minebea is also now looking at reuse possibilities. The remaining concentrated waste is automatically pumped into an IBC for removal. Paul Jarratt, who heads up the Aqua-Save Technologies division of component cleaning specialist Mecwash Systems, said: 'Before the installation, the wastewater that was removed from the site entailed a cost of some GBP850 every four weeks.

'It is now anticipated that no more than one IBC per year will need to be removed from the premises, which clearly adds up to a significant saving and thus a minimised installation payback period,' he added. Formerly known as Rose Bearings, NMB-Minebea has clients in the international aerospace market and handles a range of material, including steel, brass and aluminium. Haysman said: 'We are accredited to ISO 14001 so environmental performance is clearly a critical part of our operation.'.

Aerotech has completed and launched its low-cost Pro series linear stages. It can now offer a total of 68 standard models with travel from 50mm to 1,500mm in a choice of four stage widths from 115mm to 280mm for high-throughput, medium-precision positioning. The modular range features Aerotech's hard-cover/side-seal system that provides entire stage protection for arduous manufacturing environments such as laser machining.

With high-load-capacity linear-motion guide bearings and servo-motor-driven precision ballscrews, available in normal or 'faster' pitches for speeds of more than 1.4m/s, the range is suitable for demanding multi-axis-positioning applications across manufacturing and test. The Pro series has been designed as an adaptable family of positioning stages that allow original equipment manufacturers (OEMs) and system integrators to select and mix models to match their machine-building requirements.

For typical applications, the 115mm and 165mm narrow-width stages may be used for upper axes and the wide-base 225mm- and 280mm-wide stages fulfil load bearing support in lower axes. According to the company, almost any combination for multi-axis positioning is possible with X-Y combinations from just 50mm x 50mm and gantry-style multi-axis designs to beyond 1.5m travel. Longer, custom-designed travel options for each width are also possible where flat mounting and adequate stage support can be maintained.

Aerotech claims that the modular range has similar accuracy, repeatability and environmental specifications throughout, as well as a consistently neat and stylish visual appearance. A choice of a standard 5mm-pitch and higher-speed 20mm- or 25mm-pitch ballscrews also offers the possibility to increase throughput speeds in applications where positional specifications are less demanding. Across the range, repeatability is within +/-1 micron for 5mm-pitch ballscrews and +/-2.5 microns for 25mm-pitch variants.

Positioning resolution, with a 2,500 line encoder, is 0.5 microns for the 5mm-pitch ballscrew version, with custom encoder options available for higher resolutions if required. For applications where the Pro series maximum speeds and/or positional-accuracy characteristics are a limiting factor, the range may be mixed with linear-motor-driven alternatives that utilise the same hard-top/side-sealed design. Aerotech's ALS series direct-drive technology stages include linear encoder feedback and yield an increased acceleration and top-speed performance along with augmented accuracy and precision.

The company also plans to introduce form-fit alternatives across the Pro range using its direct-drive linear servo technology. To manage overall costs and match the customer's budget requirements, each Pro series stage is offered with a number of options, including a tabletop hole pattern to suit X-Y or rotary-stage mounting or not to have a tabletop fitted at all. Comprehensive alternatives also extend to NEMA 23 or 34 servo-motor selections and orientation options include space-saving fold-back motor designs.

Multi-axis alignment, test specifications, limit switches and Z-axis brackets are also available and are priced on a request basis. The Pro series' one-piece hard-cover and vertical side-seal arrangement protects and naturally deflects debris away from the internal stage mechanics, offering an advantage over traditional bellows or sliding top-seal designs, according to Aerotech. Additionally, an optional brush cleaning strip may be fitted to the moving carriage to remove the build-up of machining waste and to prevent debris from accumulating on the hard cover.

The improved level of protection is intended to extend working life and to reduce downtime and maintenance while maximising production throughput and uptime. The Pro series stages may be supplied as standalone variants, with matching Aerotech servo amplifiers or as a part of complete 'ready-to-run' systems with a choice of motion controllers.
Biasi Develops ActivA Unique Boiler Range

Biasi UK has developed ActivA, a new range of high efficiency A rated condensing boilers boasting a unique heat exchanger. The launch of ActivA is further testimony to the company's commitment to strengthen its position in the UK domestic gas boiler market. At the heart of ActivA is a newly developed pre-mix condensing heat exchanger that is manufactured in a corrosion resistant, pressure moulded aluminium. Its sectional construction means it can be easily adjusted for different boiler outputs and its 'multipass' design ensures very low resistance for both combustion and water passage.

This unique heat exchanger carries a five year guarantee. Designed to provide outstanding heating performance at an affordable price for almost all types of domestic properties, the compact range boasts some of the smallest boilers available - at just 700mm high x 400 wide and only 290mm deep - thereby allowing installation in cupboards. As well as a line-up of feature-packed combi and system models that provide a host of advanced features, each boiler offers a choice of controllers and flueing options up to 10 metres.

Further development sees a state-of-the-art digital control panel assist with ActivA's display information, programming and servicing, and several optional controllers serve to improve control and efficiency. Optional controllers include a complete management kit with programmable digital thermostat to help regulate the central heating temperature and provide extended control for the user, together with a mechanical or digital clock and outside weather compensator. Three combi models in the ActivA range - 25C, 30C and 35C - provide exceptional hot water flow rates at over 14 litres per minute and a high performance heating output up to 30.7 kW.

Three system boiler models - 18S, 25S and 30S - are available, and five open vent models that are due to be launched later in the year ranging from 12 to 30kW, will provide an ideal solution for boiler changes in traditional installations. Commenting on this latest range, Biasi's Managing Director, Paul Baxter said: "The new ActivA range serves to provide the installer with a comprehensive portfolio of condensing boilers designed to satisfy both new build and replacement requirements". He added: "Complete with a very competitive price tag, ActivA also provides outstanding value for money and offers further opportunities for installers to benefit from Biasi's unique loyalty reward scheme 'Pro-fit' which is linked to the purchase of our A rated boilers".
St Germans Pumping Station Is Sika Watertight

Sika Watertight Concrete has been used on the new land drainage and flood risk management pumping station, St Germans. Sika Watertight Concrete is being used to build the floor slab that separates the wet volutes from the dry plant rooms in the pump hall at the new GBP38 million St Germans pumping station, currently being constructed by Main Contractor, Costain at Wiggenhall St Germans in Norfolk.

The station, the UKs largest, spans the middle level main drain, pumping land drainage and floodwaters into the tidal River Great Ouse. The new pumping station replaces the 75 year old existing facility which provides flood protection to over 24,000 residential properties and 70,000 hectares of agricultural land with a total value to the nation of GBP3.6 billion. Rising tidal levels coupled with the effects of climate change, plus the old facility coming to the end of its serviceable life, meant that a new pumping station with a higher capacity was needed.

The new pumping station scheme, which was commissioned by the Middle Level Commissioners, managers of the drainage network, is being constructed inside a cofferdam 200 metres downstream from its predecessor. Able to pump up to 100 tonnes of water per second it will have over 40% more capacity than the old facility. One of the many engineering obstacles that had to be overcome was how to waterproof this structure in a simple and effective manor, which in turn would not delay or hinder an already congested construction schedule.

The solution was to incorporate Sika Watertight Concrete, which would eliminate the need for conventional tanking methods such as renders and membranes. Lafarge supplied the concrete from an on site batching plant. The watertight concrete will effectively form a seal on the Volute channels, which will direct the water into and out of the pumps. A reinforced concrete structure has then been built to support the 6 individual pumps with six affiliated generators and fuel tanks. Sika Watertight Concrete is based upon two powerful admixtures.

Sika Viscocrete is a powerful superplasticiser that reduces the amount of water required in concrete production, whilst offering good workability and in turn reducing the volume of capillary pores within the concrete. The second admixture, Sika 1+ blocks the pores to give effective protection down to 100 metres head of water. Sika Watertight Concrete is BBA approved and has a successful track record going back over 50 years. Construction joints and other details were sealed using products from Sika's range of jointing solutions.

These range from basic hydrophilic strips to injectable hydrophilic profiles. Using the Sika Watertight Concrete system was a cost effective solution, as it saved time at both the design and construction stages of the programme by eliminating the need for external membranes and tanking systems and their inherent complex detailing and installation issues. In turn, this will give structurally integral waterproofing for the lifespan of the structure.

RIDI Lighting Education Lighting Control Product

Class Control, developed in conjunction with Hampshire County Council, offers the ability to alter the lighting conditions to match the task in hand. RIDI Lighting has launched its next generation education lighting control product and its recent installation, through Reavey and Son Electrical of Southampton, has passed the test at Burnham Copse primary school in Tadley, Hampshire.

Designed to deliver outstanding energy efficiency, as well as the optimum learning environment, whatever the external conditions, Class Control, developed in conjunction with Hampshire County Council, offers staff at Burnham Copse the ability to alter the lighting conditions to match the task in hand - be it glare free concentration on the interactive whiteboard or for general teaching.

Class Control uses a tailored control interface based on DALI protocol to allow swift and simple alteration of lighting levels via either a handheld remote control or wall mounted touch panel. Daylight sensors automatically increase or decrease output when external conditions change and absence recognition - making for a potentially significant reduction in energy consumption. "As well as the regulations aspect - Part L - lighting designers increasingly have to look at energy efficient lighting systems for a more environmentally conscious client".

"In the education sector, pressure for sustainable products can even come from the students themselves", says Mike Attard, managing director at RIDI UK. "Above all we have found that customers need confidence that a single manufacturer can understand a brief, as well as supporting and commissioning the scheme". "To do this we have installed a dedicated product manager and support team who can assist at all stages".

Because each of the core elements of RIDI's Class Control system is designed to ensure maximum lighting efficiency, its specification can make a meaningful contribution to a school's BREEAM rating. On a regular secondary school installation, 2.66 points can be regularly achieved, as was the case at Burnham Copse. The control element at Burnham Copse has been complemented with a selection of luminaires from RIDI's architectural range, including the new ultra-thin T5 F-Line which delivered balanced direct and indirect lighting in the classroom and office areas.
