  • Patent number: 7050906
    Abstract: A method, computer program product and system for monitoring and locating an object using secure communications without relying on GPS. A monitoring device may activate a monitored unit (unit monitored by monitoring device) by transmitting a seed of an algorithm and a time synchronization to the monitored unit. The seed and time synchronization may be used in conjunction with an algorithm, e.g., frequency hopping table, stored in both the monitoring device and the monitored unit, to allow both the monitoring device and the monitored unit to communicate with one another at a uniquely synchronized time and frequency thereby making it more difficult for a third party to locate the monitored unit. An alert may be generated when the monitored unit is located beyond a predetermined zone. The monitored unit may be located by activating a directional antenna in conjunction with a digital compass on the monitoring device.

  • Patent number: 6114897
    Abstract: An electronic switch is disclosed that comprises a switch element and compensation circuitry. The switch element is operable to pass a signal between signal terminals responsive to a voltage applied to its control terminal. The compensation circuitry applies a bias voltage to the control terminal that tracks an average of a voltage at the signal terminals and is offset by a substantially constant voltage magnitude. The bias voltage insures a substantially uniform resistance across the switch element as the signal varies. In one implementation, the switch element is a field effect transistor. Further, in another embodiment, compensation circuitry can be coupled to a backgate of the switch element. In this case, the compensation circuitry can apply a bias voltage to the backgate that tracks an average of the voltage at the signal terminals and is offset by a substantially constant voltage magnitude. The second bias voltage offsets the backgate to back bias the backgate to channel semiconductor junction.
