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: 8283612
    Abstract: The invention provides a planar element which is intrinsically heatable and which is particularly suitable for attachment to multi-dimensionally curved surfaces. For this purpose the planar element features particularly high deformability, achieved in accordance with the invention through a planar element having a layer sequence comprising a heating layer and a contacting layer, each of these two layers being composed of a polymeric material based on elastomers and/or on plastic polymers which have a particular elongation at break and at the same time a particular tensile elasticity modulus. Furthermore, the invention provides an adhesively bonded assembly comprising a bonding substrate and a planar element of the aforesaid kind, a method of producing a planar element of the aforesaid kind, and the use of such a planar element for heating an adhesively bonded assembly.

  • Patent number: 8217308
    Abstract: A more comfortable seat is provided by detecting whether or not a person is in a seat. A seat has a heating element 1, a seat surface temperature detector 5 that is situated below a seat surface cover and that detects the temperature of the seat surface, and a seating determination unit 6 for determining whether or not a seat is occupied. A determination is made as to whether or not a seat is occupied according to an amount of temperature change detected by the seat surface temperature detector 5 for a predetermined period of time, whereby a determination can be readily made as to whether or not a person is seated. When no one is seated, application of power to the heating element 1 is stopped, and the like, which in turn contributes to energy saving and enhancement of fuel efficiency.

  • Patent number: 8217318
    Abstract: The invention is a submersible hand warmer apparatus for warming a diver's gloved hands. The apparatus includes a sleeve having a center portion with an elongate chamber with a right access port and a left access port; and right and left sleeve portions with elastic cuffs. The cuffs can be stretched allowing the diver's gloved hands access to the chamber, and then retract, forming a seal against the diver's arms. The chamber is sized for enough heat transfer fluid, such as water, so that the temperature of the diver's hands is raised to at least 54° F. upon immersion of his hands in the water. The apparatus also includes a heating component; an energy source, such as a battery; a housing which provides structural support; an insulation that slows the loss of heat to the cold ambient water; and a controller that controls the rate that energy is consumed.

  • Patent number: 8197621
    Abstract: A planar heating element using for carbon micro-fibers and its manufacturing method have developed. The high-resistant carbon micro-fibers and carbon powder are efficiently coated to completely replace a conventional heating element using resistance heat of a nichrome wire. A single heating element is possibly formed to have a large width and an ultra thin heating element without temperature restriction by overcoming drawbacks of a carbon powder printed heating element serving as an initial module of the planar heating element. Thus, it is possible to produce the various convenient heating elements or heating modules using DC and AC electricity without restriction by solving problems in installation and use, for example, space restriction, thereby various convenient heating elements.

    Abstract: The invention relates to a flat heater, which is used for applications in the range of heating voltages of up to 1000 V, produces attainable powers of up to 2 kW/m2 and is characterized by the fact that the electrical resistance required for the heating is formed by an electrically conductive cellulose nonwoven. Metallic contacts which are incorporated ensure the connection of the conductive cellulose nonwoven to a voltage source. Polymer films applied on both sides provide mechanical and electrical protection and prevent the ingress of moisture into the cellulose nonwoven.

  • Patent number: 8143554
    Abstract: A heating element includes a plurality of folded surfaces which can be resistively heating using electrical current. The heating element can advantageously function both as a heating source and a heat transfer device, as the need for separate fins or other heat dissipation members is eliminated. In some embodiments, the heating element can be included in a fluid heating system. The fluid heating system can include a fluid transfer device configured to deliver a volume or ambient air or other fluid through the heating element. As air moves past the heated folded surface of the heating element, it is heated. Heated air can then be discharged to one or more desired locations.
