EDITOR’S CHOICE PRODUCTS VEHICLE-TO-VEHICLE COMMUNICATIONS


Renesas Electronics Corporation and Cohda Wireless are collaborating on technology developments in the fields of automotive vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. The two companies will combine Renesas’ V2X R-Car system-on-chips (SoCs) and Cohda Wireless’ V2X and CAV software solutions, to deliver a V2X reference solution that supports European and North American communications standards for V2X system development. In response to the industry expectations for U.S. Department of


Transportation (USDOT) to mandate V2X to improve road safety and efficiency in addition to the recent deployment of V2X technology in Japan, targets have been set to widely introduce secure V2X technology in multiple global regions. With over a decade of R&D on IEEE 802.11p protocol, WLAN- based technology has proven to offer reliable and secure communication for Cooperative Intelligent Transport Systems (C-ITS). Critical and time- sensitive information on all road users and roadway elements, such as traffic control devices, are expected to be shared among for improved safety and efficiency. According to USDOT estimates, V2X technology can minimise over 80 percent of non-impaired crash types. Renesas has established an ecosystem with Cohda Wireless to offer a


reference solution that will contribute to the acceleration of V2X system development. The new V2X reference solution complies with European and North America standards from the European Telecommunications Standards Institute (ETSI), Intelligent Transport Systems (ITS), Society of Automotive Engineers (SAE) and IEEE. www.cohdawireless.com


3D-PRINTED AUTONOMOUS VEHICLE


Mouser Electronics Inc., together with Local Motors and celebrity engineer Grant Imahara have debuted a video showing the working build of a transformative vehicle cockpit for a 3D-printed autonomous vehicle. It is the latest series from Mouser’s Empowering Innovation Together educational program. The video shows the new vehicle design, which is the inspiration


of the winner of a recent global design contest. The new design features a drone mounted on the rear of the vehicle that, when launched, gives the driver an unprecedented birds-eye view of the surroundings while the car is in self driving mode. The driver can then watch the drone’s footage on the windshield via a viewing screen, giving the driver a 360-degree perspective of the surroundings. Features of this innovative build combine electronic components


from Mouser’s manufacturer partners and platinum sponsors of the series, Maxim and Murata. www.mouser.com


THERMOELECTRIC ASSEMBLY COOLING


A solution for precise thermal management in compact CO2 incubators has been developed by Laird using thermoelectric assemblies (TEAs). When employed with the company’s SR-54 temperature controller, it is claimed thermoelectric assemblies can use less energy to maintain the desired temperature range, which can lower the cost of ownership when compared to standard compressor-based systems. A cell culture incubator is designed to maintain a constant


temperature and high humidity for the growth of tissue culture cells under a CO2 atmosphere. Typical temperature settings range from 4°C to 80°C, with relative humidity between 95% and 98% and CO2 concentrations ranging from 0.3 to 19.9%. Historically, temperature in CO2 incubators were controlled either by a water bath that circulated through the walls of the cabinet (water jacketed), compressor-based systems or by electric coils that gave off radiant heat. Modern units now use solid-state thermoelectric- based cooling for temperature control. www.lairdtech.com
