  • Apparatus, methods and articles of manufacture to minimize arcing in electrical connectors
    Patent number: 7149063
    Abstract: An electrical connector and methods for minimizing arcing when the connector is connected or disconnected under load are disclosed. The invention provides an arc reduction circuit with one or more regulators, such as transistors, integrated into the connector housing that sense movement of the connector and shunt the current to an impedance circuit when a potential arc condition is sensed.

  • Field telephone system
    Patent number: 5014347
    Abstract: A field telephone system having a widely dispersed set of telephone lines including a page line pair and a party line pair, audio processing equipment including telephone handsets, handset amplifiers, receiver amplifiers and paging speaker amplifiers is designed to have improved voice transmission by provision of a narrow band FM carrier system. The FM carrier system includes a device for generating a carrier frequency signal, a modulator for modulating the carrier frequency with an audio signal derived from one of the handsets at a transmitting station and circuitry for transmitting the modulated signal over a line pair to a receiving station. The receiving station includes circuitry responsive to the transmitted signal and the carrier frequency signal for extracting the audio component of the transmitted signal and for processing the extracted audio signal and for providing the processed audio signal to a handset at the receiving station.
