The PTC device contains crystalline polymer and metal or ceramic conductive filler dispersed therein. The PTC device has a resistivity less than 0.1 ?·cm. The over-current protection device has the relation: It (heating)<Ih (60° C.)×10%, where Ih (60° C.) is a hold current of the over-current protection device at 60° C. when the heating element is not activated; It (heating) is a trip current of the over-current protection device when the heating element is activated to heat the PTC device. The PTC device has high hold current, thereby allowing a battery containing the device can be fast charged with a large current. In a specific situation, the heating element heats the PTC device to decrease the hold current of the over-current protection device of low resistivity, and accordingly the PTC device can trip by a small current.

  • Patent number: 8712227
    Abstract: Fluid conduit segments are provided that include, but are not limited to integrated heating systems for protection against freezing. To this effect PTC-fabric heating elements are provided that are integrated in the fluid conduit segments and that in the negative temperature range include, but are not limited to a PTC-temperature-dependent resistance. The heating system thus provides a higher output in the negative temperature range and a lower output in the positive temperature range, i.e., the heating limits itself until temperature equalization has been reached.

  • Patent number: 8692168
    Abstract: Infrared heating panels are provided with an electrically insulative substrate that carries one or more infrared heating elements. Each heating element includes an elongated first segment attached to a first surface of the substrate and an elongated second segment electrically connected in series with the first segment. At least the first segment is a strip of an electrically resistive material adapted to emit infrared radiation in response to a current. The second segment is attached to the second surface of the substrate opposite from and in a parallel arrangement with the first segment such that a first current flowing through the heating element flows through the first segment in a first direction relative to the substrate and flows through the second segment in a second direction opposite the first direction. Saunas, heating systems, and methods for reducing electromagnetic emissions in an infrared sauna are also provided.

  • Publication number: 20140091074
    Abstract: A carrier, in particular a plastic film, comprising an electrical heating layer is described. The heating layer is applied to at least a portion of a carrier surface. The heating layer is electrically divided by one or more first separating zones, each of which is designed such that a current path changes the direction of flow thereof at the free zone ends, and one or more second separating zones, which are designed such that the current path changing the direction of flow thereof at the free zone ends is divided in at least some sections into a plurality of electrically parallel current sub-paths. One or more second separating zones are associated with at least one free zone end of a first separating zone, with the second separating zones arranged in an aligned extension to the first separating zone.

  • Patent number: 8674271
    Abstract: A breathable electrical heater element for a topical application device such as a wound dressing or a therapeutic heating pad is disclosed. The heater element is formed by photochemically etching a track pattern onto a porous metallised fabric (e.g. nickel coated woven polyester). The heater element has a skin or wound contact layer laminated to the front face of the heater element. An adhesive layer is laminated to the back face of the heater element. The adhesive layer forms an overhang to provide an adhesive border around the wound contact layer to adhere the device to the skin of a patient. Therapeutically active drugs (optionally microencapsulated) may be incorporated into the skin or wound contact layer. Operation of the heater element causes the skin or wound contact layer to release the active drugs to the skin or wound of the patient. Appropriate control of the temperature of the heater element allows control of the release of the active drugs.

  • Patent number: 8624164
    Abstract: A blanket for warming patients during surgery and other medical procedures. The blanket includes one or more temperature sensors and a shut-off timer to prevent prolonged exposure of excessive heat to a patient. Embodiments of the present invention provide a safety feature that cuts power to a heating blanket after a certain period of time has elapsed, irrespective of the feedback provided by a temperature sensor concerning the blanket temperature. That period of time is longer than it takes for the blanket to reach its threshold temperature but shorter than it takes to cause thermal burn injury.
