Abstract
An electric heating blanket system includes a flexible sheet-like heating element having a substantially uniform watt density output across a surface area thereof, when the heating element is electrically powered. A temperature sensor is coupled to the heating element at a location where the heating element will be in conductive contact with a body when the blanket is draped over the body. The system further includes a temperature controller coupled to the temperature sensor, and an electric power source coupled to the heating element and to the temperature controller, the power source being controlled to provide the watt density output for the heating element according to a temperature sensed by the sensor.
