Abstract:
Malfunction or failure of mechanical, electrical and electro-mechanical equipment, for example equipment used in manufacturing operations, is often preceded by an increase in the operating temperature of at least some portion of the equipment. A temperature-sensitive, active material containing actuator is preselected to operate at a pre-determined temperature indicative of impending equipment failure and placed contact with the equipment. If the equipment achieves the pre-selected temperature' the actuator signals this by displaying a flag or providing some other passive visual indication.
