Activating Dormant Wireless Circuitry Using Motion or Incident Light
First Claim
1. A wireless device comprising a controller in communication with a wireless transceiver, the wireless transceiver being configured to transmit and receive data on an antenna, the controller being operative to place the wireless transceiver in a low power consumption mode based on predefined energy saving control policy, the wireless device further comprising:
- an accelerometer generating an output signal indicative of motion or vibration of the wireless device, the output signal of the accelerometer being applied to cause the wireless transceiver to exit from the low power consumption mode and to enter an active mode capable of transmitting and receiving data on the antenna.

Abstract
A wireless device includes a controller and a wireless transceiver where the controller is operative to place the wireless transceiver in a low power consumption mode based on predefined energy saving control policy. In one embodiment, the wireless device includes an accelerometer generating an output signal indicative of motion or vibration of the wireless device where the output signal of the accelerometer is applied to cause the wireless transceiver to exit from the low power consumption mode. In another embodiment, the wireless device includes a photovoltaic module generating an output voltage signal indicative of incident light impinging on the photovoltaic module where the output voltage signal of the photovoltaic module is applied to cause the wireless transceiver to exit from the low power consumption mode.
