Signal detection and recognition employees coordinated illumination and capture of images under to facilitate extraction of a signal of interest. Pulsed illumination of different colors facilitates extraction of signals from color channels, as well as improved signal to noise ratio by combining signals of different color channels. The successive pulsing of different color illumination appears white to the user, yet facilitates signal detection, even for lower cost monochrome sensors, as in barcode scanning and other automatic identification equipment.

A method for transporting real-time data such as voice over a packet-based infrastructure, and a switch for use with that method, are disclosed. In this method, datagrams from multiple data streams are packaged in a single tunnel packet for transport across a network to an intermediate switching point (switch). To reduce bandwidth, each datagram in the tunnel packet (e.g., tunneled datagram) can be sent in a compressed-header format identified by a context identifier (CID) for its data stream. The switch saves context state for each tunnel and CID it is receiving packets for. The switch deaggregates received tunnel packets into tunneled datagrams and associates each datagram with its context state. Based on the destination indicated in its context state, each datagram it re-aggregated in an outgoing tunnel packet bound for a next switch or the destination endpoint itself.

An arrangement and method in a communication system such as an Orthogonal Frequency Division Multiplexing (OFDM) radio receiver for reducing the impact of interference from an intermittent interfering signal transmitted by an interfering system which may be co-located with the OFDM system or may be remotely located. Each OFDM symbol in a received OFDM signal includes a guard interval (GI), a middle portion, and a last portion identical to the GI. The arrangement determines which portion of each OFDM symbol is contemporaneous with the interfering signal and time-shifts a fast Fourier transform (FFT) window in the OFDM receiver to minimize or eliminate FFT processing of samples of the OFDM symbol that are contemporaneous with the interfering signal, thereby minimizing the impact of the interfering signal.

An apparatus and method for the identification of arcing phenomena in a faulted electrical network. By continually updating a model for the load on an electrical branch, an estimate of the behavior of that load may be calculated. Since electrical arcing faults result in a chaotic behavior that is difficult to describe, when arcing occurs, the model will be unable to adequately describe the arcing behavior and this inability indicates a fault condition, in response to which, power may be removed in full or in part from the faulted electrical network. In some embodiments, a current shunt is used to distinguish between source side and load side arcing. Some embodiments utilize a solid state switch as both current shunt and interruption means.
