    • A system and method of passive approach detection is provided. The method comprises: transmitting a plurality of data signals corresponding to multiple power levels respectively from a fob device based on motion detected in the fob device; each of the plurality of data signals includes initial bytes encoded with a power level and transmitter identification (ID); receiving one or more of the plurality of data signals at a receiver based on the distance between the fob device and the receiver; filtering out signals at a secondary processor by comparing one or more of the plurality of data signals received to a predetermined list of signals valid for reception; and transmitting a wake-up signal to a primary processor based on the comparison, the wake-up signal enabling the primary processor to transition from a sleep mode to a wake-up mode.

    • A vehicle transceiver module is provided for use in a synchronous communication system including the vehicle transceiver module and one or more key fobs, each of the key fobs including a key fob transceiver for transmitting and receiving signals. The vehicle transceiver module includes transceiver circuitry, a controller, a storage device and power control circuitry. The transceiver circuitry receives the signal transmitted by the key fob transceiver and provides it to the controller. The controller is coupled to the transceiver for determining an offset value associated with one of the key fobs in response to an offset time duration between a reception time of the signal from the key fob and a first expected reception time of the signal from the key fob. The storage device is coupled to the controller for receiving the offset value associated with the key fob from the controller and stores the offset value along with information identifying the key fob. The power control circuitry is coupled to the transceiver circuitry for providing operational power thereto. In addition, the controller is also coupled to the power control circuitry and provides a begin transmission signal thereto to power up the transceiver circuitry for transmission of a signal to the key fob at a transmission start time determined by the controller in response to the offset value associated with the key fob and a second expected reception time.

    • A handheld electronic device of the present invention includes a display, a memory, a motion sensor, and a controller. The memory is configured for storing a viewable output of at least one software application. The controller is in communication with the display, the memory, and the motion sensor. The controller includes a first control logic that generates a first image on the display representative of a portion of the viewable output of the software application. The first image has a field of view (FOV), where the viewable output includes an inner region and an outer region. A second control logic adjusts the FOV of the first image based upon movement of the handheld device. A third control logic displays a second image of a cursor in the inner region. A fourth control logic displays the second image of the cursor in the outer region.
