Temperature and windshield crack detector

摘要

An apparatus and method for temperature sensing and for detecting cracks or breakage of a windshield. A resistance element is connected to the windshield and a resistance monitoring circuit is connected to the resistance element for monitoring an electrical property of the resistance element. A physical integrity monitoring device can be connected to the resistance monitoring circuit for determining the physical integrity of the windshield based upon the monitored electrical property of the resistance element. Also, a temperature calculator can be used to determine a temperature based upon the monitored electrical property associated with the resistance element and upon a relationship between resistance and temperature that has been stored in a memory device.
