Mazda home-brews industry first hardware-in-loop car system verification rig

Mazda has used hardware-in-the-loop, including a robot, to test and verify the function of a complete car electronic system. This is in addition to the traditional practice of testing and verifying individual units and sub-systems separately. “Increasingly, one system’s operation is dependent on results from other systems. In addition to testing systems individually, multi-system tests ...

Updated: Fully printed flexible display offers low power for simple IoT devices

Electrochromic materials are the key to low-cost simple displays, according to Swedish firm Rdot Displays, which claims wide viewing angles and high contrast for its reflective technology. Mass-production of flexible displays is possible on plastic substrates without needing metal or ITO layers – by either sheet-to-sheet or roll-to-roll printing. The underlying technology involves organic materials ...

Differential amps have 94dB minimum CMRR

Analog Devices has released a set of differential-in differential-out amplifiers win a minimum CMRR (common-mode rejection ratio) of 94dB. Based on the existing LTC6363 differential amplifier which needs external resistors, they have built-in matched resistors. “Resistor matching is equivalent to a 0.002%. Initial gain accuracy is 45ppm maximum and varies by only 0.5ppm/°C maximum over temperature,” ...

Compound Semiconductor Catapult gets its cash, but still hides its location

The Compound Semiconductor Applications Catapult has received the £51m money ear-marked for the creation of its headquarters, at a location in South East Wales that its management will not reveal. It is thought that an existing building will be leased, and that the secrecy is for commercial reasons. Currently, Catapult staff are based in Cardiff. These ...

17.3% is organic solar cell efficiency record

Chinese researchers are claiming an organic solar cell record – 17.3% efficiency under standard sunlight conditions from a solution-processes structure – as opposed to more-complex vacuum processing. The cell is a tandem device, where wavelength coverage is increased by using two different junctions. In this case the materials were tuned so that the junctions complement ...

Updated: Radio meta-surface aids object detection and tracking

Inspired by acoustics, a French-US team has found a way to locate objects in a room simply by their microwave scattering characteristics. Similar to diffusing reverberant acoustic wave spectroscopy (DRAWS), the techniques relies on the room having walls that reflect radio waves – reflecting sufficiently to fill the room with a complex field of interference ...

Link between blue light and age-related macular degeneration

“We are being exposed to blue light continuously, and it’s no secret that blue light harms our vision by damaging the eye’s retina,” said University of Toledo researcher Dr Ajith Karunarathne. “Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration.” The mechanism identified involves a vitamin A ...
