Abstract: A communication switch having heterogeneous ports. The heterogeneous ports are connected to nodes which may be operating at different frequencies and which may have different optical characteristics. In addition to the ports, the switch of the present invention includes a matrix controller and a matrix switch which is connected to the ports. When two ports want to communicate, the matrix controller commands the matrix switch to establish a physical connection between the ports. According to the present invention, data is transferred between the ports via the matrix switch in a serial and asynchronous manner. Because data is serially and asynchronously transmitted, high data rates through the matrix switch may be achieved.

Abstract: An electrochromic matrix display of the kind in which the display electrodes are supported on a substrate above a corresponding matrix of transistor switches employs constant current writing and potentiostatic erasure. The transistors are switchable by signals applied on respective gate lines to pass electric current on the respective drive lines to their display electrodes. Gate and drive selection means define the active gate and drive lines. During erasure, the potentiostatic erase voltage is applied to both ends of the selected drive lines simultaneously to speed up the current limited asynchronous erase operation. Optionally, the display may be driven alternately from opposite ends of the drive lines during a line-by-line writing operation.

Abstract: A synchronizer and phase aligning method that provide signal smoothing and filtering functions as well as slip-cycle compensation, and allow for multichannel digital phase alignment, bus deskewing, integration of multiple transceivers within a single semiconductor chip, etc. A delay line produces a plurality of delayed input replicas of an input signal. A clock phase adjuster produces a sampling clock signal from a reference clock signal. The sampling clock signal may be phase adjusted to be offset from the input signal. After certain smoothing and filtering functions, selection logic detects a phase relationship between the sampling clock signal and the input replicas and identifies a closely synchronized signal for output. Using this identified replica signal, slip-cycle compensation and retiming logic outputs a compensated data output signal synchronized with the reference clock signal. Also, an integrated multiple transceiver produced using the phase alignment technique is presented.
