    摘要: Optical waveguide isolator (121) for monolithic integration with semiconductor light emitting diodes such as Fabry-Perot or ring laser diodes. The present optical isolator (121), with optical input port (95) and output pod (96), comprises a branching waveguide coupler (56). This branching waveguide coupler (56) has a waveguide stem (60) splitted at one end into two waveguide branches (57, 58) such that a light wave fed via said input pod (95) into a first of these branches (58), is guided via the waveguide stem (60) and the output pod (96) out of the device. A light wave fed to the isolator's output pod (96) is guided along the stem (60) and coupled into the second waveguide branch (57).

    摘要: A method for contactlessly testing for opens and shorts in conducting paths within or on a nonconducting substrate. There are a plurality of conducting pads on the surface of the substrate. Charges are contactlessly generated, e.g., by an optical beam, in at least one selected pad inducing a voltage thereon and on pads electrically connected therewith through one of the conducting paths. A two dimensional electron flux is contactlessly caused to be emitted from the selected pad and at least one other pad of the plurality of pads, e.g., by an optical beam. The flux emitted from the pads depends on the voltage on each pad. The flux is detected to distinguish pads in electrical connection.

    摘要: A method and a device for combining at least two data signals having a first data rate into a single data stream having a second data rate higher than the first data rate for transmission on a shared medium or vice versa. The device has at least one port for receiving at least two data signals and a port addressing unit for extracting data from the data signals received by the ports. The port addressing unit is configured to place the extracted data at predetermined positions in the single data stream to be transmitted on the shared medium and at least one control data insertion unit is provided for placing control data in the single data stream.

    摘要: A computer system controls ordered memory operations according to a programmatically-configured ordering class protocol to enable parallel memory access while maintaining ordered read responses. The system includes a memory and/or cache memory including a memory/cache controller, an I/O device for communicating memory access requests from system data sources and a memory controller I/O Interface. Memory access requests from the system data sources provide a respective ordering class value. The memory controller I/O Interface processes each memory access request and ordering class value communicated from a data source through the I/O device in coordination with the ordering class protocol. Preferably, the I/O device includes at least one register for storing ordering class values associated with system data sources that implement memory access requests.
