  • Patent number: 5175727
    Abstract: The present invention discloses a communication system network that comprises a plurality of communication systems and a processing multiplexer. The communication systems, which may be either conventional communication systems and/or trunked communication systems, transmit digitized audio signals and communication system data to the processing multiplexer. Based on signal destination data, which is part of the communication system data, the processing multiplexer processes the digitized signals and routes the resultant signals to the appropriate signal destinations of the communication systems.
    Type: Grant

  • Patent number: 5070499
    Abstract: In a communication system network that comprises a plurality of communication systems and a processing multiplexer, the processing multiplexer comprises a processing module, a buffer module, a multiplexer module, and a buffer address module. The buffer module temporarily stores processed audio information, which is produced by the processing module, in one of several sections. The processed audio information is stored in section of the buffer module based on which signal destination it is for. If the processed audio information is destined for a signal destination that is assigned to a slot in the first distination interface bus, the processed audio information is stored in the first buffer location. When the processed audio information is placed onto the destination interface buses, it done so in a round robin fashion such that the communication system may operate in a real time frame.

  • Patent number: 4961070
    Abstract: A radio console having a CRT display that allows channel control windows (CCWs) to be moved about a work area or from a summary list to a work area and back again. The CCWs may be of various sizes, and the display provides helpful indications of suitable locations to where selected windows may be moved. The display also allows preselected windows to be linked one to another, and to ensure that when one of the linked windows is moved, the remaining linked windows are moved in tandem with it. Also, if a window is manipulated to cause it to occlude an adjacent window, a distinct border is provided for the occluding window to indicate to the user that such occlusion heat occurred.

  • Patent number: 4570261
    Abstract: There is disclosed a system and a method for isolating faults and recovering a distributed system of the type including a plurality of modules to optimized operation. At least some of the modules are active fault recovery modules and include fault detecting means for initializing a fault check routine and sensing faults within the distributed system. Voting means are associated with each active module for placing a vote during each fault check routine in response to a detected fault. Collective vote determining means record the votes of the active modules after each fault check routine and recovery sequence initializing means initializes a fault isolation and recovery sequence in response to a given number of consecutive collective votes exceeding a predetermined value.

  • Patent number: 4514703
    Abstract: An automatic level control system is described for use with a voice processor which generates an AGC control signal to vary the gain applied to an audio input signal. The system includes a dynamically adjusting peak detector for detecting noise peaks and voice peaks while ignoring voice lulls which occur after a voice peak. Detected peaks are processed by an improved voice/noise sensor which develops a first output signal when voice is detected and a second output signal in the absence of detected voice. These output signals are received by a gain control circuit which is adapted to prevent the AGC control signal from increasing system gain for an indefinite interval in response to the second signal, and to permit normal variation in the AGC control signal in response to the first signal.
