UK makes harnesses and lights for German electric sports car

Convert of Kent has designed a cable harness for a German automotive manufacturer’s all-electric sports car, recently completing pre-series development work. The next three years, according to Convert, could see is manufacturing more than 60,000 cable harness for the car, involving two million crimp connections per year and cable the length of 2,500 football pitches. ...

ADC-FPGA-DAC board processes 12bits at 5.4Gsample/s

Teledyne e2v and Logic-X have developed an FPGA mezzanine card incorporating GHz ADCs and DACs from Telydyne. The 12bit EV12DS460A DAC provides an analogue bandwidth extending beyond 7GHz “facilitating multi-band, direct digital synthesis up to 26.5GHz K-band with a latency of three clock cycles”, according to Logic-X. The 12bit EV12AS350B ADC combines 5.4Gsample/s, an input ...

Liquid gas electrolyte for lithium metal batteries?

Liquified gas electrolytes could be the key to batteries that use lithium metal anodes, according to the University of California San Diego. Replacing the carbon anode of lithium-ion cells with metallic lithium could theoretically improve energy density in rechargeable batteries, but they have not become popular because the inclusion of metallic lithium makes the batteries ...

Global model available to predict solar power installation productivity

Danish researchers have created a a worldwide solar energy model that predicts what type of solar photovoltaic (PV) installation will produce what power on which part of the planet. “We’ve collected 38 years of global solar radiation, weather and temperature data with a spatial resolution of 40km x 40km for the entire globe, and compared ...

Government launches ‘Electronic waste and the circular economy’ inquiry – you can respond

The House of Commons’ environmental audit select committee has launched an inquiry into electronics waste and recycling, and is asking for advice. “The UK produces more e-waste than the EU average. We are missing EU targets and are one of the worst offenders for exporting waste to developing countries, who are ill equipped to dispose ...

Gate driver for 1.7-4.5kV IGBTs and SiC transistors

Power Integrations created an isolated gate drive system for up to four paralleled 1.7-4.5kV power modules – either IGBT or silicon carbide mosfet. Called Scale-iFlex, it is dual channel so, for example, independent control of high and low-side switches in a half-bridge is possible. “The system is optimised for the latest 1,700V to 3,300V rated ...

Data-over-sound SDK for Arm Cortex-M

London-based data-over-sound company Chirp has released an SDK for Arm Cortex-M4 and M7 processors. The SDK exists as a static library (~740kbyte), providing a software-defined data-over-sound solution optimised for Arm processors, with an API for sending and receiving data through existing audio chains between existing loudspeakers and microphones. The SDK implements the physical and data ...

Getting robots to do what you want – without unintended consequences

Researchers at Stanford University are seeking ways to tell autonomous systems what to do, that reduce the chance of unintended consequences when the instructions are obeyed to the letter. “In the future, I fully expect there to be more autonomous systems in the world and they are going to need some concept of what is ...
