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 ink(s) printed in the form of a series of interconnected lines having a definite or definitive pattern and fixedly disposed on a 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 pattern to cause the conductive ink pattern to radiate heat;
a controller operatively coupled to the power source and the conductive ink pattern, 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 portable controllable thermal warming device including a thermal ink heating element having a conductive ink pattern comprised of interconnected lines in a definite pattern fixedly disposed on a substrate, a controller operatively coupled to a power source and the conductive ink pattern, the power source adapted to deliver a voltage to the conductive ink pattern causing the conductive ink pattern to radiate heat, the controller adapted by way of a sensor to control the voltage delivered to the conductive ink pattern and adjust the voltage in response to the operating characteristic and the means for controlling the voltage by a wire link or a wireless remote signal.
