SELECTIVE CURRENT REDUCTION ENABLED WITH ELECTRICALLY DEACTIVATED KEY FOB

摘要

Smart key fob with an integrated rechargeable battery and a replaceable battery. Transfer of charge from the replaceable battery to the rechargeable battery is configured to occur only during a period of time when the key fob remains motionless to reduce RF interference with polling operation of the key fob's transceiver to determine presence of the mother-vehicle nearby. Optionally, the poling operation of the transceiver is reduced or ceased during periods of motionlessness of the key fob.

主权项

1. An electronic device, comprising:
a first electrical battery integrated therewith; a second electrical battery in electrical communication with the first battery; a motion sensor configured to detect a movement of the electronic device; and a processor operably connected to the first and second batteries and the motion sensor and configured to effectuate charging of the first electrical battery using energy from the second electrical battery only when the electronic device is stationary, based on results of detection performed by the motion sensor.
