Abstract: A light control apparatus includes a diffuser plate, a light source, a light pipe, and a light blocker. The diffuser plate includes at least one opening therein. The diffuser plate includes feature located around the opening in the diffuser plate that exposes a portion of the diffuser plate. A light source positioned proximate a second surface of the diffuser plate is optically coupled to a light pipe positioned around a portion of the opening near the second surface of diffuser plate. A light blocker is positioned near a second portion of the at least one feature. The light blocker is positioned between the light source and the second portion of the feature, the light blocker having an opening therein to allow light to pass from the light source to the diffuser plate proximate the second portion of the feature.

Abstract: A peripheral device communication system includes a communications medium having physical network hardware. The system also includes a first network device capable of issuing to the physical network hardware a request to communicate a datagram with greater priority than any other communications request. This datagram encapsulates a memory register access command. The system further includes a second network device having addressable memory registers and capable of issuing to the physical network hardware a request to communicate a datagram with greater priority than any other communications request. This datagram encapsulates a response to a memory register access command.

Abstract: A method is provided for tracking an object's position. One or more semiconductor-based sensors obtain measurements of an energy field associated with the object. A processor applies an algorithm to the measurements to generate one or more values representing a position of the object in a coordinate system. The energy field may comprise a magnetic field, for example. The object may comprise a magnet, for example.
