Abstract: An optical waveguide has a window for receiving optical signals re-directed by a beam splitter and a heating element associated with the window.

Abstract: A system is proposed for characterizing the performance of a sportsman. The system is capable of using motion data it receives describing a movement during the sport, to distinguish the type of sport, and type of stroke, which is being played. The system can furthermore detect the quality of a stroke involving an impact (e.g. an impact between an item of sports equipment and a ball), based on the observation that a good stroke will be in a “sweet spot” in which the amount of vibration caused by the impact is limited.

Abstract: A system includes an external light supply to a silicon photonic chip. The light supply includes a primary light source, a secondary light source, an optical coupler, an optical splitter, and a dark sensor. The optical coupler is to combine any output from the primary light source and any output from the secondary light source into an input to the silicon photonic chip. The optical splitter is located in an optical path between the primary light source and the optical coupler, and is to divert part of the output from the primary light source. The dark sensor is to receive the diverted part of the output from the primary light source and to selectively activate the secondary light source based on the diverted part of the output from the primary light source.

Abstract: Example methods and apparatus to remove dust from an optical waveguide assembly are disclosed. An example apparatus includes a window to be located on an optical waveguide assembly. The example apparatus includes a first piezoelectric member coupled to the window. The first piezoelectric member is to vibrate the window to remove dust from the window in response to an electrical signal.

Abstract: In one implementation a device connector includes a first electronic device magnet, second electronic device magnet, and third electronic device magnet to connect to a power supply. The power supply magnet can be oriented to the opposite pole of one of the electronic device magnets.

Abstract: A switch module includes multiple ports, each port electrically communicating with a port light emitting diode (LED), where each port LED is configured to emit light to indicate power delivery out of the port, and each port LED is configured to emit one of a plurality of light colors to indicate a power level delivered out of the port.

Abstract: In one example implementation in accordance with the present disclosure, a process is provided. The process includes entering a first mode of operation where a plurality of light sources are permitted to illuminate. The process further includes entering a second mode of operation where the plurality of light sources associated with the first switch are not permitted to illuminate, and where the entering of the second mode of operation is in response to not detecting a presence for a time period. The process still further includes entering a third mode of operation in response to receiving a command, where only a subset of the plurality of light sources are permitted to illuminate and the remainder of the plurality of light sources are not permitted to illuminate.

Abstract: A master node selects a plurality of slave nodes that share a common slave address to receive a data communication. The master node multicasts the data communication to the plurality of selected slave nodes via an inter-integrated circuit bus having a serial data line and a serial clock line.
