System and method for detecting motion of an object
First Claim
1. A system to detect movement of an object, comprising:
- a sensor that is operative to sense at least a pressure condition within an enclosed space of the object based on an operating mode of the system; and
a control system that controls the operating mode of the system based at least in part on whether movement of the object is detected, the movement of the object being detected based on a variation in the at least a pressure condition over time.

Abstract
Systems and methods are disclosed to for detecting movement of an object. In one embodiment, a system is disclosed to detect movement of an object (e.g., a tire). The system includes a sensor that is operative to sense at least a pressure condition within an enclosed space of the object based on an operating mode of the system. A control system controls the operating mode of the system based at least in part on whether movement of the object is detected. The movement of the object is detected based on a variation in the at least a pressure condition over time. The system can be implemented as part of a tire pressure monitoring system.

10. A tire pressure monitoring system comprising:
-
a pressure sensor that is operative to sense a pressure condition associated with a tire;
a control system that controls the pressure sensor to sense the pressure condition at a sample rate that varies based on whether movement of the tire is detected; and
a variation detector that detects the movement of the tire based on determining at least a predetermined level of variation in the sensed pressure condition over a plurality of samples of the sensed pressure condition. - View Dependent Claims (11, 12, 13, 14, 15)

16. A tire pressure monitoring system comprising:
-
means for sensing pressure of a tire and for providing an indication of the sensed pressure;
means for controlling the means for sensing pressure to sense the pressure based on whether movement of the tire is detected; and
means for detecting movement of the tire as a function of variation in the indication of the sensed pressure over time. - View Dependent Claims (17, 18, 19)
