  • Publication number: 20080161015
    Abstract: Replica correlation processing, and associated representative signal-data reduction and reconstruction techniques, are used to detect signals of interest and obtain robust measures of received-signal parameters, such as time differences of signal arrival and directional angles of arrival, that can be used to estimate the location of a cellularized-communications signal source. The new use in the present invention of signal-correlation processing for locating communications transmitters. This enables accurate and efficient extraction of parameters for a particular signal even in a frequency band that contains multiple received transmissions, such as occurs with code-division-multiple-access (CDMA) communications.

  • Patent number: 7130334
    Abstract: The present invention includes a cellular pilot signal detector or searcher for use in a cellular mobile communications unit. The signal detector uses a matched filter to detect a pilot signal transmitted from a cellular base station. The matched filter includes a plurality of taps and a plurality of delays located between adjacent taps. The signal components of a received digital signal are held on the taps of the matched filter by the delays. The matched filter compares the signal components of the received signal to an expected or searched for digital pattern. The matched filter puts out a relatively large signal if the received digital signal matches the expected digital pattern. The matched filter can also be used in parallel with a correlator.

  • Patent number: 7072647
    Abstract: A system and method for parallel programming an electronic device's memory during manufacturing. In one embodiment, the electronic device is programmed in parallel with test code and a portion of the system code prior to board level testing. The test code is then used during board level testing of the electronic device. Once board level testing is complete, the electronic device is programmed with additional system code to complement the existing system code, whereby system level testing is then performed.

  • Patent number: 6453169
    Abstract: A communication device including a power key located on an outer surface of the housing which may provide multiple functions, but is resistant to initiation of undesired handset functions. Control circuitry within the communication device may be configured to ignore any actuation of the power key with a duration less than a determined time period. The control circuitry performs a first function if the power key is depressed for a first duration, and performs a second function when the power key is depressed for a second duration. For example, depression of the power key for a short period of time may silence and incoming call alert, whereas depression of the power key for a longer period of time will turn the communication device on or off.

  • Patent number: 6366241
    Abstract: A method and system for determining with enhanced accuracy a line of bearing and related signal characteristics of a mobile wireless transceiver in a cellular-telephone communications system is presented. Three or more conventionally configured antenna elements are used to provide a high resolution line of bearing estimate through disambiguation of positional parameters associated with inter-element signal characteristics derived from signal products. The high resolution line of bearing estimate can then be used to determine the location of the transmitter.

  • Patent number: 6119013
    Abstract: A system and method for locating a mobile transceiver relative to plural fixed sensor stations. The system includes plural sensor stations that receive a signal transmitted by the mobile transceiver. A probable position of the mobile transceiver is determined based on a time of arrival of the signal and an angle of arrival of the signal received at the plural sensor stations.

  • Patent number: 6108555
    Abstract: A method and apparatus for locating a mobile radio communications transceiver in a cellular-telephone or cellular-like communications system use a simplified system for passive monitoring of the signals emitted by the transceiver. Two receiving base stations can determine the timing of signal arrivals from the remote transceiver. This timing information is then combined with collateral, position-sensitive information to determine the likely location of the transceiver. The present invention has particular applicability to roadway transportation in that it facilitates enhanced emergency services and roadside assistance in response to calls for assistance, and it permits the passive monitoring of traffic flow.
