  • Patent number: 7808398
    Abstract: A transformer system for sensing load requirements and controlling a transformer accordingly to reduce power consumption when the load is in a stand by mode. One embodiment of the system includes a transformer implemented to receive an input and transform the input for use by a load, a sensor connected between an output of the transformer and the load, a communication link including the sensor and being connected between the transformer and the load, and a control switch connected to the transformer and sensor through the communication link. The sensor detects a mode of load operation and communicates a corresponding load mode signal over the communication link.

  • Patent number: 7573373
    Abstract: An anti-carjacking system includes a transmitter programmed to receive a selected vehicle identification number or other code for use with a car assigned with that particular number or code. The system further includes a receiver associated with the computer system of the car so identified by the selected vehicle identification number and means for disabling normal driving operation of the car. There is further provided means for sending a disable command from the transmitter to the receiver so that the particular car with the selected vehicle identification number is rendered non-operational. The system may be implemented in various embodiments including a modified car radio system and a RFID embedded license plate configuration. Methods related to vehicle operation and occupant safety are also provided.

  • Patent number: 7394397
    Abstract: Methods and apparatus for controlling power to a load device. The apparatus include a standby loss prevention module or a transformer system including the module. The module and system are directed to sensing load requirements and controlling a transformer accordingly to reduce power consumption when the load is in a stand by mode. One method includes interposing a control switch between an electrical supply and a load device, determining when the load device requires full-level operational power, activating the control switch to interpose a step-up transformer between the electrical supply and the load device, providing full-level operational power to the load device, and deactivating the step-up transformer when the load device is not in use.
