Patent ID: 6888108

Claim:
An electrically powered device, comprising: a pliable heating member having a resistive heating element; and a power supply for supplying power to the resistive heating element of the pliable heating member, comprising: a power input arrangement adapted to receive input power having a high voltage exceeding a predetermined low voltage threshold; an isolation-type power conversion device including an input and an isolated output, wherein the input is interconnected with the power input arrangement; a switching arrangement interconnected with the power conversion device, wherein the switching arrangement is configured and arranged to provide continuous intermittent operation of the power conversion device; and a low voltage power output arrangement interconnected with the isolated output of the power conversion device, wherein the low voltage power output arrangement is interconnected with the resistive heating element of the pliable heating member; wherein the intermittent operation of the power conversion device by the switching arrangement is operable to supply continuous low voltage output power having a voltage below the low voltage threshold to the resistive heating element of the pliable heating member through the isolated output of the power conversion device and the low voltage power output arrangement.
