LONDON — Pyreos Ltd. (Edinburgh, Scotland), a developer of infrared sensors that spun out of Siemens in 2007, has raised $4 million to help it pitch for design wins in smartphones and tablet computers. The round was led by Robert Bosch Venture Capital GmbH, Seraphom Capital, Siemens Technology Accelerator and the Scottish Investment Bank.
The company reckons its low-power IR technology when applied to gesture and proximity detection consumes about one-thousandth that of competing technologies. Pyreos' passive infrared sensor technology is already in use in industrial gas and flame markets and for handheld spectroscopy in the dairy, winery, and lubricant industries.
The Pyreos combined gesture and proximity sensor uses microwatts of power which allows designers of portable consumer electronics to create "always on" and "wake up on motion" gesture recognition equipment. Pyreos plans to launch two products; one that recognizes proximity and gestures at 20cm range and another that performs the same combined function at one meter.
