Abstract:
A circuit integrity detection system for use in detecting the integrity of a sensing wire in a heating pad wherein the integrity of the sensing wire is checking the inputs from a first and second A/D converter connected to opposite ends of the sensing wire.
Abstract:
A controller for use in textile heating devices, such as heating pads, heating blankets, and the like is provided. The controller provides a display system for conveying to a user the selected heat setting. Such display system is useful in low light condition, where a user cannot readily see the heat setting indicia on the controller. The display system includes a plurality of lighted elements. The lighted elements are illuminated at different intensity levels to indicate the selected heat setting, In this manner, a user is provided with a visual frame of reference to indicate the selected heating setting. Namely, the differentiation between the intensity levels enables a user to visual determine the selected heating setting by the position of a higher intensity lighted element in relationship to lesser intensity lighted elements.

Abstract:
A sleep system including a thermal pad and a thermal control unit in thermal communication with the thermal pad. The thermal controller is configured to automatically adjusts a temperature of the thermal pad during a sleep cycle time according a programmed routine. During the preprogrammed routine, the thermal control unit maintains the temperature in the thermal pad at a first temperature T1. After a first time period S1 from the initiation of the sleep cycle, the thermal control unit adjusts the temperature in the thermal pad a ΔT, for example to a second temperature T2. The second temperature T2 is dependent of the first, preset, temperature T1 and the ΔT. The thermal pad temperature is maintained at the second temperature T2 for a majority of the sleep cycle. At a time period S2 before the end of the sleep cycle, the temperature in the thermal pad 12 adjusted a ΔT to a third temperature T3.
