Arm unloads IoT unit

Arm is unloading its IoT unit onto its parent Softbank, taking the operation off the Arm balance sheet. Arm’s two IoT businesses, IoT Platform and Treasure Data will be transferred by the end of September. Moving away from its core business of designing processor IP was a controversial move for Arm because it looked as ...

Thermography adopted for battery production in-line inspection

Comau of Turin has added thermography to its vision system family Machine Inspection Recognition Archetypes (MI.RA). Designed for industrial-scale battery manufacturing, MI.RA/Thermography uses thermal imaging and artificial intelligence to perform non-invasive automated assessment and control of welded joints, to ensure battery integrity and prevent waste. Its non-destructive testing methodology protects cycle times without changing the ...

30V mosfets half-bridge plus Schottky in one package

Vishay has introduced a 30V n-channel MOSFET half-bridge power stage that combines a high side TrenchFET and low side SkyFET in a 3.3 x 3.3mm package. The mosfets are optimised for their respective tasks in a buck converter (see table and diagram). One has a maximum on-resistance of 4.5mΩ at 10V (7.0mΩ at 4.5V) and ...

Etch a metasurface with without ruining the physical surface

Researchers from the University of Southampton have found a way to make an optically-active meta-surface without altering the physical shape of the surface. Infra-red thermal control coatings and non-linear optics are potential applications. Metasurfaces are structures designed to control, for example, electromagnetic radiation using repeating structures, typically with sub-micrometer dimensions for light. Routes to forming ...
