Abstract
A method for activating a remote device is provided. In response to a determination that a remote device is within a first mode signal range of a vehicle and the remote device is moving, the method activates a second mode communication module of the remote device.
Claims20
A method for conserving power in a remote device, comprising:
- receiving, at the remote device, a first signal emitted by a vehicle;
- evaluating motion data from the remote device to determine a movement status of the remote device, wherein the evaluating is performed in response to receiving the first signal;
- and
- transitioning a first wireless communication module of the remote device from a low power mode to an active mode, when the motion data indicates that the remote device is moving.
A method for activating a remote device, comprising:
- in response to a determination that a remote device is within a first mode signal range of a vehicle and the remote device is moving;
- activating a second mode communication module of the remote device.
A system comprising a remote device and a vehicle module, the remote device and the vehicle module being configured to wirelessly communicate with one another using a first mode and a second mode, and the remote device and the vehicle module being further configured to perform a method comprising:
- detecting, at the remote device, presence of the vehicle module within a first mode signal range;
- polling an internal sensor of the remote device to obtain motion data;
- analyzing the obtained motion data to determine whether the remote device is moving;
- and
- activating a second mode communication module within the remote device when the analyzing determines that the remote device is moving.
