  • Publication number: 20090032516
    Abstract: The technical nature of this invention is the development of a flexible bag, which has a flexible-reflective interior foil that is protected from being damaged by the objects to be placed inside the bag for warming such as fabric items, gloves, pajamas, baby clothes, or construction materials that need to be kept warm. Items are kept warm by a heating pad which is plugged into a standard 120 volt outlet or into a 12 volt DC converter. The bag is portable or can be left in a location where the warmed items need to be used. In industrial or construction applications, the addition of a strap to the bag allows it to be easily carried or hung over a railing for easy dispensing of the items that are being kept warm in the bag. The bag retains heat for an extended period of time when unplugged.

  • Patent number: 7132630
    Abstract: The use of conductive polyaniline fibers for resistive heating applications is described. Unlike metal wires and conductive-polymer coated fibers, under certain conditions, electric voltages or currents used to generate heat in the fibers were found to produce irreversible changes to the polymer backbone that destroy its electrical conductivity but not its structural integrity. The temperature that these changes occur varies with dopant and fiber diameter, and can be tailored to specific applications. Since these changes occur at lower temperatures than the temperature at which dopant molecules within the conductive polymer are lost or decomposed, both of which lower the conductivity of the material, polyaniline fibers can be used for resistive heating applications where the heating element is in the vicinity of the skin of the wearer thereof.

    Abstract: An electric load control device of a heating unit of a heating blanket comprises an actuating unit; a power supply for supplying power to the device; a microprocessor as a control center of the device for generating at least one pulse signal; the microprocessor being actuated by the actuating unit; and a driving unit; the driving unit receiving the at least one pulse signal from the microprocessor for actuating the heating unit to generate heat to heat the heating blanket; the driving unit serving to actuate the heating unit. An actuation time period of the heating unit is controlled by the pulses from the driving unit. In the driving unit, the negative parts of the pulses from the microprocessor are converted into positive pulses so that all the pulses become positive pulses; after the pulses pass through the driving unit, only selective positive pulses are passed.

  • Patent number: 7060950
    Abstract: The invention provides a linear and/or plane heating element, and a thawing mat, and a hot mat comprising the linear and/or plane heating element that provides necessary heat quantity at low electric power without burning fossil fuel and the like. A heating element is provided produced by coating laminated polyester on a plane painted by paint that adds nickel-indium compound oxide to the upper surface of polyester film to solderlessly connect electrodes to both ends to connect a power supply to the electrodes. The present invention provides a thawing mat and hot mat that entirely and uniformly coat the heating element having high conductivity and heating efficiency by adding nickel-indium compound oxide having high conductivity and heating efficiency to thermally deposit. Thus, maintenance cost and electricity expense can be saved, and both high quality and social cost can be achieved.

  • Patent number: 7038177
    Abstract: A fabric article that generates heat upon application of electrical power is formed, for example, by knitting or weaving, to form a fabric prebody. An electrical resistance heating element in the form of a conductive yarn is incorporated into the fabric prebody, e.g., laid in, e.g., in the knit-welt or tuck-welt configuration, the electrical resistance heating elements extending between opposite edge regions of the fabric. Conductive elements are provided for connecting the electrical resistance heating elements to a source of electrical power.
