50mm diameter ring type encoder for dial-type controls Alps Electric Europe has developed the “EC50A Series” ring type encoder for use in controls for car air conditioning and audio systems or major home appliances. Dial-type devices have often been used in the past for car air conditioning and audio system controls. These devices are often designed to enable embedding of a control switch or a small LCD in the center of the dial. But design freedom cannot be enhanced without widening the device’s inside diameter (central opening). Space around the control panel is limited, hence, opening up the inner diameter is one way to make some room for an extra switch, LEDs or a small LCD, while retaining the same external dimensions. The EC50A Series is claimed to be the industry’s first 50mm ring type encoder, with a large 37mm inside diameter that provides a central opening around twice as large as Alps’ earlier product. The EC50A Series also has a guide formed on the inner wall to reduce rattle when the customer attaches a knob. Furthermore, original mechanical design and precision processing technologies were applied to achieve a premium operating feel.

The entry level lighting devicess are manufactured on Plessey’s 6-inch MAGIC (Manufactured on GaN I/C) line at its Plymouth, England facility. The new LED products are aimed at a variety of solid state lighting and entertainment-type lighting products including accent lighting, wall washing, wall grazing, striplighting and a variety of pulse lighting applications. Barry Dennington, Plessey’s COO, said: “The MAGIC LED product range is expanding in both light output and efficacy. The PLB010350 is our first, high current device operating at anywhere from 350 mA through to 2 A in pulse applications. We have also been able to demonstrate the versatility and the potential of the Plessey GaN on Si technology by constructing an LED with a relatively large die area. This new 350 mW product demonstrates the inherent flexibility we have for the manufacture of LEDs with a 6-inch GaN on silicon substrate in an integrated circuit manufacturing line. We are seeing continual improvements in output efficiencies in the lab which means we will continue to launch new products in line with our product release plan.” The use of Plessey’s MAGIC GaN line using standard semiconductor manufacturing processing provides yield entitlements of greater than 95% and fast processing times providing a cost advantage compared with standard LEDs of similar quality.

The battery free RFID switch is compatible with commercial EPC C1G2 readers and communicates a unique ID and the associated switch status data without the need of battery supply on the sensor tags. The tag comes in a variety of antenna designs and sizes to adapt its performance to the required application. The reading distance for the battery-free pressure-sensor tag is around 2.5m and it can be embedded in a wide variety of materials such as plastics or concrete. The device features one of three different Connectors for users to connect their switch: a 2.00mm pitch SIL latched vertical pin header, a 2.00mm pitch male 1x2 header or just the 1x2 header footprint (pitch 2.00mm). The X1GLADIO is suitable for use in applications where monitoring of open/closed or connected/disconnected components is needed. Farsens S.L. www.farsens.com Radar chipset makes ADAS more affordable In the automated driving scenarios of the future and in many other safety-oriented advanced driver assistance systems (ADAS), Radar is one of the central sensor technologies. Chipmaker Freescale now has introduced a comprehensive system-level solution for automotive Radar based advanced driver assistance systems. The new Qorivva MPC577xK Microcontroller (MCU) and MRD2001 77 GHz Radar transceiver chipset provide the embedded technology necessary for affordable Radar based ADAS solutions with fewer components, helping increase the adoption of such features in mainstream vehicles. The Qorivva MPC577xK MCU, built on Power Architecture technology, provides high-level digital and analog integration in a single-chip solution for Radar applications, removing up to four additional major printed circuit board (PCB) components and reducing system-level cost, PCB space and software complexity. The MCU also provides high performance for intense computational tasks with key integrated digital accelerators and features a state-of-the-art signal processing toolbox that contains all of the hardware modules required for processing sampled signals from short-, medium- and long-range Radar applications. Performance data from the European New Car Assessment Programme (Euro NCAP) suggests that safety systems, such as Autonomous Emergency Braking (AEB), can reduce accidents by up to 27% and can lead to a considerable reduction in road injuries. Euro NCAP plans to incorporate the AEB assessment for cars sold in Europe into its five star rating scheme beginning 2014. Using Freescale’s new Radar transceiver chipset, automakers can implement long-range and mid-range frontal Radar for adaptive cruise control and autonomous emergency braking systems, as well as manage blind spot and side-impact detection – all through a single, scalable, multi-channel solution. Designers can pair the Radar transceiver chipset with the Qorivva MCU to achieve a total system solution for both low-end and high-end Radar modules.
