  • Avalanche victim locating transceiving apparatus
    Patent number: 6484021
    Abstract: A rescue transceiver apparatus for transmitting a signal to and receiving a signal from another rescue transceiver apparatus is provided. The apparatus comprises a housing and a radio signal transmitter for the transmission of a radio signal in a transmitting mode with a first predetermined frequency with the radio signal transmitter being mounted within the housing. A receiver is provided for selectively receiving the first predetermined frequency from the radio signal transmitter in a receiving mode. The receiver comprises a first antenna mounted completely within the housing, a second antenna mounted completely within the housing with the second antenna being disposed substantially perpendicular to the first antenna, and a virtual third antenna mounted completely within the housing with the virtual third antenna being derived from phase information generated by the first antenna and the second antenna.

  • Communications system utilizing FSK/PSK modulation techniques
    Patent number: 5521602
    Abstract: A passive transponder incorporating non-volatile ferroelectric memory is powered by inductive coupling to a proximately located controller. A communication system and method utilizes the controller to send data and commands to the transponder by an FSK modulated RF signal in order to cause the transponder to either read selected data from, or write selected data to, the non-volatile memory and transmit the same back to the controller utilizing PSK RF modulation. The communication system and method operates either full duplex or half duplex with the controller causing the transponder to simultaneously write data to its non-volatile memory as the memory is read out and transmitted to the controller thereof. Features of the invention include, signal transmission between the controller and transponder occur concurrently; the controller's FSK signal is modulated between 125 KHz and 116.3 KHz; the transponder's PSK signal is 62.
