University of Hong Kong researchers have used artificial intelligence to perform a brain scan with a conventional rare-earth magnet rather than a large superconducting magnet, and without a screened room. The ‘ultra-low field magnet’ – according to MRI nomenclature – was designed using almost 90kg of samarium cobalt as its field source – used because ...

Infineon has introduced a dual-channel smart gate driver for high-side load switches, design to control heavy loads in a 48 V board net through an SPI interface. Called 2ED4820-EM and ruggedised against vehicle transients, it can tolerate negative voltages at Vbat down to -90V and voltages up to +105V. Bus current sensing is included, with ...

In an IoT network, even if a server and its assets are secured, there may be millions of sensors connected to it, and each of these is an open window into its core. Until the security industry puts more focus on hardware security at the edge, vulnerabilities will abound, argues Dr. Shahram Mossayebi of Crypto ...

Texas instruments has revealed a buffer amplifier developed especially for oscilloscope inputs from dc to GHz. BUF802 signal paths “Oscilloscope manufacturers have got a choice: develop a discrete JFET input stage and risk limited performance, or develop their own asic,” TI general manager of linear amplifiers John Caldwell told Electronics Weekly. Developing a custom asic ...
