A smart speaker can be used to locate you within a room, with no prior knowledge of room shape, according to a University of Illinois at Urbana-Champaign research team. It also, at lease partially, maps the room. It uses the microphone array in the speaker, an Alexa in this case, to provide data for an ...

Pickering has created a high voltage reed relay, that can stand off 1.5kV and switch up to 1kV. Called Series 131, they are single pole (normally-open) single-in-like devices with a 12.5 x 3.7mm footprint and 6.6mm height. The high voltage rating is specified with resistive loads. “At these high voltages, even stray capacitance can generate ...

Supermicro introduced a sealed pole-mounted server for 5G and ‘intelligent edge’ applications at Embedded World last week. Sealed to IP65, inside is a choice of Intel Xeon D or 2nd Gen Xeon Scalable processors, and three PCI-E expansion slots for GPU or FPGA accelerator cards. For example, the Xeon D-2183IT is a 100W TDP processor ...

Osram has created a phosphor-converted red LED for car rear combination lamps – for fog lights, for example. It has moved to phosphor conversion, rather than native red emission, to beat temperature droop. The part is called Synios P2720 CR – the initials for ‘converted red’. “One of the main issues with monochromatic LEDs for ...
