  • Patent number: 8143559
    Abstract: A heating pad is provided. The heating pad includes a heating element and a control circuit operatively connected to the heating element for providing a predetermined level of power thereto. An isolation device interconnects a power source to the control circuit. The isolation device has a first open configuration preventing transmission of electrical power therethrough and a second closed configuration allowing transmission of electrical power therethrough. The control circuit terminates power to the heating element in response to the heating element exceeding a first temperature limit. The isolation device moves from the closed configuration to the open configuration in response to the heating element exceeding a second temperature limit.
