TL;DR: In this paper, a wirelessly-chargeable heating pad is coupled to an article in a removable manner and used in combination with a charging device to perform wireless electrical charging, where the charging device converts the electrical power into an alternate current signal that is transmitted to the receiver circuit.
Abstract: The present invention provides a wirelessly-chargeable heating pad, which is coupled to an article in a removable manner and is used in combination with a charging device to perform wireless electrical charging. The wirelessly-chargeable heating pad includes a receiver circuit, a heating element, and a pad body. The receiver circuit includes a rechargeable battery. The heating element is electrically connected to the rechargeable battery. The heating element and the receiver circuit are both mounted to the pad body. The article includes a removable mounting structure, so that the wirelessly-chargeable heating pad is removably coupled to the article through the removable mounting structure. The charging device, after receiving electrical power, converts the electrical power into an alternate current signal that is transmitted to the receiver circuit. The receiver circuit receives and converts the alternate current signal into electrical power that is then stored in the rechargeable battery. The rechargeable battery subsequently supplies the electrical power to the heating element to give off heat.

TL;DR: In this paper, a heating mattress or pad for warming a patient during a hospital procedure can include a heating element positioned between a first foam portion and a second foam portion, at least partially enclosed in a fluid-resistant cover.
Abstract: Personal warming systems and apparatuses for use in hospitals and other settings. In one embodiment, a heating mattress or pad for warming a patient during a hospital procedure can include a heating element positioned between a first foam portion and a second foam portion. The heating element and the foam portions can be at least partially enclosed in a fluid-resistant cover. The heating element can be operably connected to a control unit that allows an operator to select between a plurality of temperature options for the heating pad. In another embodiment, the heating pad can include one or more radiolucent, or at least generally radiolucent, features that will not appreciably obscure x-ray images taken of a patient positioned on the heating pad. In one aspect of this embodiment, the radiolucent features can include one or more of a carbon-based heating element, an optical temperature sensing device, and/or a thermally responsive state-changing device.

TL;DR: In this paper, a thermal-electric heating element sandwiched between the upper and lower foam pads is used to warm a person on a support structure, and a form-fitting waterproof cover encloses at least a portion of the upper foam pad and the thermal electric heating element.
Abstract: A heating pad system useable in one embodiment for warming a person on a support structure. In this embodiment, the heating pad system comprises an upper foam pad, a lower foam pad, and a thermal-electric heating element sandwiched between the upper and lower foam pads. A form-fitting waterproof cover encloses at least a portion of the upper and lower foam pads and the thermal-electric heating element. In one aspect of this embodiment, the heating pad system includes a power unit for providing electrical power to the thermal-electric heating element, the power unit including a control panel having at least one temperature selector, the temperature selector for selecting at least one heating pad temperature.

TL;DR: In this paper, a flexible, electric heating pad with a self-limiting heating element is described, where the heating element includes a pair of relatively spaced conductors surrounded by a positive temperature coefficient (PTC) material.
Abstract: A flexible, electric heating pad having a self-limiting heating element is provided. The heating element includes a pair of relatively spaced conductors surrounded by a positive temperature coefficient (PTC) material. A layer of electrically insulating material surrounds the PTC material. The PTC material includes a polyolefin resin having a relatively low flexural modulus. The heating element is disposed in a generally serpentine configuration within passages formed in the covering material of the heating pad. The passages are formed by joining together layers of covering material using ultrasonic welding or other suitable ways. The temperature of the heating element is controlled using controller circuit which utilizes a solid state timed interval control circuit. A safety circuit is provided for non-resettably disconnecting electrical power from the heating element if short or open circuit conditions occur therein. A temperature indicator and a variable automatic shutoff circuit are also provided with the controller circuit. A method of making the heating pad is also provided.

1 Jun 1977TL;DR: In this paper, a flexible graphite fiber-loaded impregnated paper saturated with a binder is used to ensure and maintain intimate electrical contact between the graphite fibers to provide an extremely thin highly flexible drapable therapeutic heating pad.
Abstract: The heating element includes a flexible graphite fiber-loaded impregnated paper saturated with a binder to ensure and maintain intimate electrical contact between the graphite fibers. In one form, two segments of the graphite fiber-loaded paper are coupled in series through a common bus bar and are electrically coupled to an SCR control circuit using a thermistor as a temperature responsive device. The graphite fiber-loaded paper with thermistor and electrical leads are encapsulated between cover sheets to provide an extremely thin highly flexible drapable therapeutic heating pad. Another form of heating pad includes providing the graphite fiber-loaded paper in the form of strips bonded to a plastic substrate. Electrical leads are attached and the substrate is enclosed by a cover sheet to provide a highly flexible heating pad. Two discrete methods of forming the latter heating pad are disclosed including silk screening and die pressing operations.
