MEMS Sensor Enabled RFID System and Method for Operating the Same
First Claim
1. A method for providing environmental monitoring of an item with an electronic system comprising:
- operating the electronic system in a deep-sleep mode at a minimal level of power consumption by disabling operation of nonessential portions of the electronic system;
activating the electronic system at a monitoring rate to sense an environmental parameter to which the item is subjected;
sensing a value of the environmental parameter to which the item is subjected;
comparing the sensed environmental parameter with the value of the environmental parameter just previously sensed to derive a rate of change of the environmental parameter;
adjusting the monitoring rate to track the rate of change of the environmental parameter;
storing the value of the sensed environmental parameter; and
returning the electronic system to the deep-sleep mode.

Abstract
A method for providing environmental monitoring of an item with an electronic system includes the steps of operating the electronic system in a deep-sleep mode at a minimal level of power consumption by disabling operation of nonessential portions of the electronic system; activating the electronic system at a monitoring rate to sense an environmental parameter to which the item is subjected; sensing a value of the environmental parameter to which the item is subjected; comparing the sensed environmental parameter with the value of the environmental parameter just previously sensed to derive a rate of change of the environmental parameter; adjusting the monitoring rate to track the rate of change of the environmental parameter; storing the value of the sensed environmental parameter; and returning the electronic system to the deep-sleep mode.
