    Abstract: The antenna(12) of a transceiver couples through a low pass filter(14) to the input port(30) of a high pass filter network(32). The high pass network is designed to reflect a very high impedance to its input port when its output port(40) is at ground potential. The transmitter portion(62) of the transceiver couples to the input port of the network with the receiver coupling to the network output port. A semiconductor diode(48) couples from the output port(40) to ground potential. In the receiver mode the combination, low pass and high pass filters, couple received signals in the desired frequency band to the input of the receiver.

    Abstract: The disclosed noise limiter processes the detector output through both low path and high pass filters. The low pass filter produces a DC signal representatuve of both the detector DC level and the recovered audio signal level. The high pass filter passes only the recovered audio signal. For peak detector levels at or below the 100% modulation level the diode is forward biased and passes the audio signal to the noise limiter output for further receiver processing. Peak detector levels exceeding 100% modulation reverse bias the diode.

    Abstract: In a squelch circuit(40) adapted for use in the receiver portion(10) of a transceiver having a switching means to select either the transmit or receive mode, the receiver includes the means for providing an AGC signal. The squelch circuit comprises hysteresis means(50) for unmuting the receiver at the first AGC threshold level and decaying means responsive to the switching means.

    IPC: H01L41/04

    Abstract: A unique printer heat employs a plurality of bimorph benders to drive a wire matrix. The blenders are of the circular, high power type, having centrally located coupling washers. A housing supports the benders which are stackally mounted the resin such that the washer openings form a central cavity which is aligned with an opening in the housing. Each wire is coupled with a corresponding bender to be ballistically driven thereby. The wires are routed through the central cavity and wire guides for actuation out the housing opening.

    Abstract: PURPOSE: A method and a device for managing transmission of cellular uplinks are provided to manage transmission of uplinks in an interference cell of a cellular wireless communication system. CONSTITUTION: A controller receives information(305). The controller determines whether a communication device transmits pending data using a data repetition mode(310). The controller determines a specific data repetition mode based on the size of an interference(320). The controller transmits a command to a communication device to transmit pending data using the specific data repetition mode.
