Abstract:
A remote access device and methods of operation thereof are provided for accessing a physical object or location. The remote access device includes an accelerometer, a wireless transmitter, and control circuitry. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a first change in motion states of the remote access device. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a second change in motion states of the remote access device. The control circuitry further causes the wireless transmitter to transition between the first operating mode and the second operating mode in response to receiving signals from the accelerometer indicating a third change in motion states of the remote access device.
