Abstract
A method for adjusting a power setting of a key fob includes receiving an input signal from a sensor by a processor. The processor determines, based at least in part on the input from the sensor, that a person is holding the key fob. Based on the determination that the person is holding the key fob, the processor adjusts an initial power setting of the key fob by a predetermined amount.
Claims19
A method comprising:
- receiving, by a processor in a key fob, a detection signal from at least one sensor;
- determining that an object is proximate a transceiver antenna in the key fob based at least in part on the detection signal from the at least one sensor;
- and
- adjusting an initial power setting of a transmitter in the key fob by an adjustment factor as a result of determining that the object is proximate the transceiver antenna.

A key fob comprising:
- a memory device;
- at least one sensor programmed to output a detection signal;
- and
- a processor programmed to access the memory device and further programmed to receive the detection signal, determine that an object is proximate a transceiver antenna in the key fob based at least in part on the detection signal, and adjust an initial power setting of a transmitter in the key fob by an adjustment factor if the processor determines that the object is proximate the transceiver antenna.
