First CXPI-compatible transceiver IC
Rohm is claiming a first, with a transceiver IC for the CXPI automotive communication protocol – aimed at body control applications such as steering wheel switches, air conditioning and instrument panels. The BiCDMOS chip, called BD41000FJ-C, enables multiplexing between electronic control units (ECUs) to reduce wiring (see diagram). “To decrease weight, many systems adopt LIN for ...
Pressure sensor tells you which floor
Altitude-based floor level tracking is possible using barometric pressure sensors, claims sensor-maker Bosch, which is suggesting them for asset tracking, personnel tracking, shopping mall guidance and emergency applications such as E911 and Blue force. Californian service-provider NextNav is using them as part of a positioning system that allows phones to determine their location in indoor and ...
Some 3D printed objects are a little poisonous
Researchers at the University of California, Riverside have found parts produced by some commercial 3D printers are toxic to certain fish embryos. The research started after researcher Shirin Mesbah Oskui used 3D printed parts for an experiment with zebrafish embryos, and the embryos died unexpectedly. “These 3D printers are like tiny factories in a box,” ...
Waterproof vent flows more air
Gore‘s next-generation PolyVent High Airflow flows twice the air of its predecessor, and it has an improved O-ring that is UL-rated for flammability resistance. “Engineered to handle the large pressure differentials caused by extreme weather conditions, the PolyVent High Airflow provides the same ingress protection as Gore’s prior generation of high airflow vents. For enclosures ...
Novel Hall IC gives 90°outputs from many different magnets
Allegro has used two-dimensional Hall sensing to deliver quadrature outputs from a variety of magnet rings. Its point is, that if both Hall sensors on a chip are in the same plane, then outputs are only 90° out of phase for magnets of one particular pole period – related to the distance between the two ...
LuxLive: Plessey to show concept lighting
UK GaN-on-silicon LED maker Plessey will be demonstrating smart lighting concepts at LuxLive in London later this month, starting with a lightbulb that combines illumination with the functions of a mobile phone bluetooth headset – it has microphone, speaker, processing and Bluetooth radio. “Lights help change the use of a room and because there are ...
Soraa builds second GaN-on-GaN LED fab
GaN-on-GaN LED maker Soraa is building a semiconductor fab in Syracuse New York, in partnership with the State of New York. The firm, which has a fab in Fremont California, is working with SUNY College of Nanoscale Science and Engineering, shell completion is scheduled by the end of this year, and production for the second half of ...

350W medical PSU needs no forced air
The CUS350M series of ac-dc power supplies from TDK are rated at 350W and have both medical and ITE certification to IEC 60601-1 and IEC 60950-1 standards. Requiring no forced air for cooling, the PSUs are intended for use where audible noise cannot be tolerated: hospital, dental, broadcast and professional audio application, for example. They ...
