    摘要： An arrangement for damping the resonance in a laser diode includes an additional layer (25) which together with the conventional laser diode form a structure (35) of a bipolar transistor. Therein, the additional layer serves as the collector, the cladding layer (12) next to it as the base, and the active region (11) and the other cladding layer (13) as the emitter. A capacitor (30) is connected across the base and the collector. It is chosen so that at any frequency above a certain selected frequency (f.sub.c) which is far below the resonance frequency (f.sub.res) the capacitor impedance is very low, effectively shorting the base to the collector.

    摘要： A portal system for secure, aggregated and centralized management and access of disparate customer service and social networking environments is disclosed. A user interface provides multiple, parameter-based automated service scripts, each configured to utilize customer information. The scripts link to vendor-specific, scenario-specific, and social networking-specific interfaces that have common user interface elements. Shared and dedicated reverse automation gateways are configured to emulate the step-by-step self-service aspects of web sites and interactive voice response systems. The portal system eliminates or reduces inbound toll-free telephone charges for vendor contact centers and additionally links the same to social networking systems.

    摘要： Described is a system and method for tracking an asset. The system may include a plurality of wireless access points and a computing arrangement communicating with the access points. The arrangement determines a location area of the device as a function of first data and a location of each of at least three access points of the plurality of the access points. The first data includes at least one of first signal strength data and second signal strength data. The first signal strength data is indicative of a strength of a first signal transmitted by the device and received by the at least three access points. The second signal strength data is indicative of a strength of a second signal transmitted by the at least three access points and received by the device. The location area is an area within a predetermined reception range of the at least three local access points. The arrangement determines the location of the device within the location area as a function of second data and a further location of each of the at least three further access points of the plurality of access points. The second data is indicative of a travel time of a third signal from the device to each of the at least three further access points.

    摘要： Simplified data message terminals and data communicating voice terminals are described for providing additional functionality in a facility using a wireless data communication system. The simplified data message terminals provide message and paging communication to employees or customers in a simplified terminal configuration using the existing data communication system. By performing voice to data and data to voice conversions, the same system provides voice communication without interruption of data communication services.
