CIRCUIT INTEGRITY DETECTION SYSTEM FOR DETECTING THE INTEGRITY OF A SENSING WIRE IN ELECTRICALLY HEATED TEXTILES

摘要

A circuit integrity detection system for use in detecting the integrity of sensing wire in a heating pad wherein the integrity of the sensing wire is checking the inputs from a first and second A/D converter connected to opposite ends of the sensing wire.

1. An electrically heated textile comprising:
a heating element in communication with an NTC material, wherein a first signal is generated through the heating element at a first frequency; a sensing wire for detecting a hotspot created by the heating element; a first A/D converter connected to a first end of the sensing wire; a second A/D converter connected to a second end of the sensing wire; and a signal detector for detecting the signal from the first and second A/D converters.
