Patent
Semtech | Date: 2015-08-12

A proximity sensor for detecting proximity of a body portion in a first region while avoiding unwanted detection of a body portion in a second region, based on the capacities seen by a plurality of electrodes. An application of the inventive detector to a mobile phone, whereby the display is switched off, or various energy saving measure are taken, when the proximity sensor determines directional proximity with a body part, indicating that the user has brought the phone to the ear for placing a call.


Patent

A circuit is disclosed having a component having repeatable distortion characteristics; and a drive circuit for providing a drive signal and comprising a non-linear filter for pre-compensating for distortion introduced by the component having repeatable distortion characteristics in response to the drive signal, the distortion having a non-linear response to the drive signal.


Patent
Semtech | Date: 2015-09-09

A wireless communication method between a plurality of end-points by a plurality of base stations, based on frames that have a CSS-modulated preamble followed by a data body modulated at a narrower bandwidth, either by CSS or by a UNB modulation. The system permit to avoid or mitigate collision between packets and to increase the network capacity, maintaining the simplicity of detection inherent of CSS modulation.
