Iridium antenna is small enough for headsets and trackers
Claimed to be the world’s smallest antenna tuned for Iridium satellite services, the HXDC1600 has been released by Helix Geospace. The antenna tuned for Iridium satellite services can operate safely near the human head with minimal performance degradation, said the company. It is designed for use in mobile handsets, wearable trackers and personal safety devices.
MEMS sensors add machine learning in the edge and electrostatic sensing
A third generation of MEMS sensors are intended for consumer mobiles and smart industries, healthcare, and retail.
SoC uses computing-in-memory for speech processing at the edge
Computing-in-memory technology is poised to eliminate the massive data communications bottlenecks associated with AI speech processing at the network’s edge, said Witinmen. The company has worked with Microchip Technology’s subsidiary Silicon Storage Technology (SST) to develop an embedded memory that simultaneously performs neural network computation and stores weights. Microchip Technology announced that its SuperFlash memBrain neuromorphic memory has been combined with the Witinmem neural processing SoC. The SoC is claimed to be the first in volume production that enables sub-mA systems to reduce speech noise and recognise hundreds of command words, in real time and immediately after power-up.
