From All About Circuits: Google ATAP is bringing touchless interfaces to the market using a miniaturized radar chip no bigger than a dime. This is Project Soli.
Soli’s radar sensor is a marvel in many respects. For one thing, it solves a long-lived issue when it comes to gesture-recognition technology. Previous forays into the topic yielded almost-answers such as stereo cameras (which have difficulty understanding the overlap of fingers, e.g.) and capacitive touch sensing(which struggles to interpret motion in a 3D context).
Google ATAP’s answer is radar.
Radar is capable of interpreting objects’ position and motion even through other objects, making it perfect for developing a sensor that can be embedded in different kinds of devices like smartphones... (full article)
Space, or the lack of it, can be a challenge when placing barcodes or Data Matrix symbols on components. However, readable barcodes are critical to component traceability, time/date stamping, work in progress (WIP) tracking, and recall management.
MicroHAWK UHD smart cameras can decode very small and difficult-to-read barcodes, including Data Matrix two-dimensional (2D) symbols and direct part marks (DPM). Users can rely on the MicroHAWK UHD to read symbols with an x-dimension almost invisible to the naked eye!
