The present invention provides a portable system for cooling that is integrated into a wearable garment or carrying device. The device includes a Peltier thermoelectric cooler coupled to the garment. The thermoelectric cooler comprises a cold side plate and a hot side plate. The cold side plate is oriented proximate to the body of the wearer. The cooling device further comprises a thermal shield. The thermal shield comprises a thermally reflective surface that faces the wearer side of the garment. The device comprises a thermal conduction sheet coupled to the cold side of the thermoelectric cooler. The device further comprises a cold pack thermally coupled to a side of the thermal conduction sheet. The device comprises a blower configured to blow air across the hot side of the thermoelectric cooler and away from the garment.

A heating element composite comprises a substrate of one or more fibers or threads and an electrically-conductive polymer coating comprising an electrically-conductive polymer material deposited onto the one or more fibers or threads. A thickness of the electrically-conductive polymer coating is at least about 100 nanometers and the electrically-conductive polymer coating covers at least about 75% of an external surface area of the one or more fibers or threads of the substrate. The resulting heating element composite has a sheet resistance of from about 2Ω/□ to about 200Ω/□.

An embodiment of the disclosure provides a heater package including a substrate, a first barrier layer, at least one heater, and a second barrier layer. The first barrier layer is disposed on a surface of the substrate and has a first treatment layer on a side away from the substrate. The heater is disposed on the substrate and includes a heating layer and at least one electrode. The at least one electrode and the heating layer contact with each other. The second barrier layer covers an upper surface and a sidewall of the heater and has a second treatment layer on an opposite side or the side away from the substrate. A ratio of a thickness of the first treatment layer to a thickness of the first barrier layer and a ratio of a thickness of the second treatment layer to a thickness of the second barrier layer range from 0.03 to 0.2.

A pPTC heating device having areas with different power densities distributed over the surface of the device. The device is constructed using a base layer composed of a pPTC material having a layer of sectioned conductive plates disposed over and under the layer of pPTC such as to control the path of the current through the device, thereby controlling resistance of the device and the power density of the device.

Disclosed herein are methods and systems to vaporize plant material including utilizing a removable disposable cartridge into a case with a receiver. Multiple zones allow for efficient heating. The receiver is configured to support heating elements and transfers heat to a containment portion of the cartridge. Heat zones can direct heat to different areas of the containment portion at a sufficient temperature to vaporize resins or oils on plant material for inhalation via the cartridge.

A heater system for an LED light assembly having a lens includes a flexible composite positioned around an outer surface of the lens. The flexible composite includes a polymer base layer, a plurality of conductive buses provided on the base layer, and a resistive layer electrically connecting the plurality of buses to form a circuit. The resistive layer includes conductor particles dispersed in a polymer matrix. The resistive layer has a crystalline first condition prior to applying electricity to one of the buses and an amorphous second condition in response to applying electricity to one of the buses.

Embodiments include a heating blanket. The heating blanket may include a heating element and a shell covering the heating element. The heating element has elastic properties and is disposed in the shape of a sheet. The shell may have one or more sheets of polymeric material bonded together adjacent a perimeter of the heating element. One or more wires having malleable properties are secured within the shell. The wires allow the heating blanket to be secured to a patient.

A heated floor panel assembly for aircraft includes an impact layer made from a 2-D or 3-D woven high temperature thermoplastic fiber matrix impregnated with a resin. The impact layer can further include woven metallic fibers. The assembly also includes a stack of structural layers, a heating layer, and a core layer for absorbing shear stress.

An attachable self-resistance heating/super-hydrophobic integrated gradient film material. The film material is made of an adhesive resin, an electrically and thermally insulative resin, a thermally and electrically conductive filler, and a thermally conductive insulating filler. The adhesive resin and the electrically and thermally insulative resin respectively form an adhesive layer and a base body, and the two are bonded together. The thermally and electrically conductive filler and the thermally conductive insulating filler are respectively added to an intermediate layer and an upper layer of the base body, to divide the base body into three gradient regions from top to bottom, wherein a super-hydrophobic structure is constructed on the surface of the uppermost area.
