Controllable thermal warming devices
First Claim
1. A portable heating system comprising a controllable thermal warming device, the controllable warming device comprising;
- a thermal heating element comprised of conductive inks printed in the form of a series of interconnected lines having a definite or definitive pattern and fixedly disposed on a single sheet of nonconductive substrate;
a power source operatively coupled to the conductive ink pattern, the power source adapted to deliver a voltage to the conductive ink to cause the conductive ink pattern to radiate heat;
a controller operatively coupled to the power source and the conductive ink, the controller adapted to control the voltage to the conductive ink pattern whereby the heating element, the power source and the controller comprise a portable unit.

Abstract
A controllable thermal warming device for delivering heat to an object by radio frequency signal. The controllable thermal warming device may include a thermal ink heating element comprising a substrate and a conductive ink fixedly disposed on the substrate, a power source operatively coupled to the conductive ink, the power source adapted to deliver a voltage to the conductive ink to cause the conductive ink to radiate heat, a controller operatively coupled to the power source and the conductive ink, the controller adapted to control the voltage delivered to the conductive ink and to detect an operating characteristic of the conductive ink and adjust the voltage in response to the operating characteristic, and means for controlling the controller by radio frequency. The controllable thermal warming device may also include a sensor to provide the operating characteristic to the controller.
