One embodiment of a method of frame detection may involve storing data indicative of a pulse duration and a number of successive occurrences of pulses having that pulse duration for each of several different pulse durations detected within a first field of a composite synchronization signal. This process may be repeated for one or more other fields of the composite synchronization signal. The data stored for each of the fields may be compared, and a frame signal may be generated dependent on an outcome of said comparing.

This disclosure describes a fabry-perot interferometer array and methods of using it for gas sensing, hyper-spectral imaging, scene projection and optical communications. Processed on a silicon, silicon-on-sapphire, or other substrates with integrated circuits, the array may be sized from one pixel to multi-mega pixels and made to cover the entire ultraviolet (UV) to long wave infrared (LWIR) spectrum, allowing it to be used in many applications. In preferred embodiments, each pixel of the array is a fabry-perot interferometer cavity, sandwiched between two parallel mirrors, whose spacing is changed by moving one of the mirrors relative to the other with a voltage applied across the cavity, tuning it to transmit a waveband with a bandwidth and a central wavelength determined by the mirror reflectivity and the cavity spacing, respectively. Thus, an array of different wavebands may be electrically tuned to transmit from the array.

A system (and a method) are disclosed for a video processing system with enhanced entropy coding performance. The system includes an entropy decoder configured to divide decoding of an input video stream into arithmetic decoding and syntax decoding. The entropy decoder includes an arithmetic decoding module, a syntax decoding module, a memory management module and a memory buffer connecting the two decoding modules. The arithmetic decoding module is configured to decode the input video stream into multiple bins of decoded input video stream and the syntax decoding module is configured to decode the bins of arithmetically decoded input videos stream into one or more syntax elements. The memory management module uses the memory buffer to accelerate the coding performances of arithmetic decoding and syntax decoding. The system also includes a corresponding entropy encoder configured to encode a video stream with improved coding performance.

A method of facilitating configuration of at least one sensor with a data transmitter communicatively coupled to an analysis engine for a building management system, wherein the application is configured to be run on a mobile device and interact with the at least one sensor during the installation. The method includes communicating, by the application, with the at least one sensor to display a visual indicator, capturing, by a camera of the mobile device, visual data representative of the visual indicator, and associating the at least one sensor with a circuit of a building power system based on the captured visual data.
