Using series regulation to operate through voltage surges is a well known technique, with the regulator fully-on during normal operation to minimise losses in the supply. For infrequent surges a linear surge protection regulator is fine, but in the face of frequent surges dissipation from a linear regulator could become an issue. For situations where ...

An Arm-based super computer chip has been revealed by Fujitsu and the Riken Center for Computational Science (R-CCS) in Japan, the team that created the record-breaking K computer (pictured) – K-computer had 68,544 eight-core SPARC64 VIIIfx processors and an efficient novel inter-processor network. Announced briefly two years ago, the chip is a prototype CPU for the computer currently ...

Vishay has introduced 8kW mica-insulated resistors in millbank size. Called GREM, the firm is promoting them as a lower cost option to stainless steel grid designs. “8kW at 40°C is 23 % higher than standard 6,500W stainless steel grid resistors in the standard millbank size,” said Vishay. “At the same time, GREM devices are 30 ...

US and Korean researches at have built a super-stretchy flow sensor into a brain aneurysm ‘diverter’ – a device much like the ‘stents’ used to repair heart blood vessels. This kind of aneurysm is a balloon-like bulge on the side of the vessel and the diverter is a wire mesh tube which is expanded inside the ...

Engineers at UCLA have designed a graphene-based photodetector that is sensitive and can work anywhere in the electromagnetic spectrum from ultra-violet to microwaves. The work is published in Nature Light Science & Applications in the paper ‘Gold-patched graphene nano-stripes for high-responsivity and ultrafast photodetection from the visible to infrared regime‘, whose title explains just about ...

Kent-based PCB manufacturer Minnitron was called in when Welsh artist Stefan Samociuk needed a gold-plated panel as part of his ‘metasurface’ series. The 484 x 484mm singl-sided PCB has 190,969 pads ranging in diameter from 0.35mm to 0.9mm, plus solder mask, and was mounted on a backlit LED panel within a surround. The metasurface series ...

Presto Engineering creates bespoke adapters to increase the performance of equipment testers. “In most cases, Presto creates a hardware solution that is built into the load board so that a standard tester could be used rather than having to buy and charge the customer for a highly specialised tester,” said the firm. “Test costs are ...

Scientists are turning to Cumbernauld-based Gas Sensing Solutions to soup-up laboratory micro-organism incubators. Used to grow culture cells and tissues, and grow bacteria in stable environments, said GSS, their controls typically only measure up to ~5% CO2 concentration levels, but some researchers need 20% CO2 or higher. This is where GSS’s CO2 sensors come in. Based ...

Microchip has created a Bluetooth 5-compliant SoC with Sony’s LDAC audio codec – although Microchip points out that a separate license from Sony is required to implement LDAC audio codec technology. “LDAC is considered the highest-quality audio codec available,” claimed Microchip. “It transmits up to 990kbit/s throughput, which is three times higher than the standard ...
