SYSTEMS AND METHODS FOR SAVING POWER IN MONITORING AND TRACKING DEVICES

摘要

This disclosure provides systems, methods and apparatus for wireless data communication. In one aspect, a device communicates with a base station. The device comprises a circuit configured to generate energy based on an environmental input. The device further comprises a storage device configured to store the energy. The device further comprises a clock circuit configured to generate a clock signal. The clock circuit is configured to power on during an active state of the device and power off during a sleep state of the device. The device further comprises a trigger circuit configured to generate a trigger signal that transitions the device into the active state when a level of the energy stored reaches a threshold value. The device further comprises a transmitter configured to transmit a message to the base station in response to generation of the trigger signal.

主权项

1. A device for communicating with a base station, comprising:
a circuit configured to generate energy based on an environmental input; an energy storage device coupled to the circuit and configured to store the energy; a clock circuit configured to generate a clock signal, the clock circuit configured to be powered on during an active state of the device and configured to be powered off during a sleep state of the device; a trigger circuit coupled to the energy storage device, the trigger circuit configured to generate a trigger signal that transitions the device from the sleep state into the active state when a level of the energy stored in the energy storage device reaches a threshold value; and a transmitter coupled to the clock circuit, the transmitter configured to receive the clock signal and transmit a message to the base station in response to the generation of the trigger signal.
