Methods and apparatuses for manipulating the temperature of a surface are provided. Devices of the present disclosure may include a thermal adjustment apparatus, such as a controller in electrical communication with one or more thermoelectric materials, placed adjacent to the surface of skin. The device may generate a series of thermal pulses at the surface, for providing an enhanced thermal sensation for a user. The thermal pulses may be characterized by temperature reversibility, where each pulse includes an initial temperature adjustment, followed by a return temperature adjustment, over a short period of time (e.g., less than 120 seconds). The average rate of temperature change upon initiation and upon return may be between about 0.1° C./sec and about 10.0° C./sec. In some cases, the average rate of the initial temperature adjustment is greater in magnitude than the average rate of the return temperature adjustment.

A composite light weight, flexible and energy efficient, thermal source energy transfer assembly for the transfer of thermal energy in articles of warmth or cold and its method of construction is described. The assembly comprises a thermal energy generating membrane having opposed top and bottom surfaces. A first thermally insulating flexible down material sheet is secured to the top surface. A second thermally insulating flexible down material sheet is secured to the bottom surface and wherein the first thermally insulating flexible down material sheet has a thermal insulating value superior to the second thermally insulating flexible down sheet to thermally insulate the thermal energy generating membrane from an ambient temperature side of the thermal source energy transfer assembly when retained adjacent a surface area of a user person to be heated or cooled by heat or cold released by the thermal energy generating membrane. The second thermally insulating flexible down material sheet absorbs and distributes thermal energy transferred thereto by the thermal energy generating membrane. Several assembly examples and applications are described.

An electrically powered warming sleeve comprised of multiple fabric layers enclosing one or more planar heating panels arranged for positioning the panels over major muscle groups. Operation of the warming sleeve is controlled by a switch, preferably with multiple “on” positions to adjust the level of heating. The switch is conveniently accessible on the exterior of the sleeve and may be made integral with LED indicators to signal the active level of heating. In some embodiments, a receptacle positioned at the proximate posterior portion of a sleeve houses a power receiving means which may be electrically connected to a rechargeable battery. Preferably, the heating panels of the sleeve are engineered to eliminate hot spots and incorporate material to emit far infrared radiation that will penetrate soft tissues of a wearer. The warming sleeve may be used to warm extremities while maintaining dexterity of the digits or as a therapeutic device.

The utility model discloses water pants with a hand warming function, comprising waterproof pants; the bottoms of the waterproof pants are connected with waterproof boots; the waterproof pants are provided with a belt; clips are installed on the front side of the waterproof pants; straps are installed on the rear side of the waterproof pants; a hand warming bag is fixedly sewed at the inner side of the waterproof pants in a position of a chest; the hand warming bag is connected with a power line; and the power line is electrically connected with a mobile power supply. The water pants comprise pants, a jacket and a power bank; the pants are provided with the belt; the pants are provided with the hand warming bag; a heating wire is arranged in the hand warming bag; and pockets are arranged on both sides of the jacket.

A portable body surface air cooling method and a device thereof are disclosed. A portable air compression and heat dissipation set at least composed of an air compression unit, an air heat dissipation passage set and a power unit. The device compresses air with normal temperature in an environment to form compressed air, transfers the compressed air through a transfer passage, dissipates the heat of the compressed air and lowers the temperature of the compressed air in the transfer process, making the compressed air with lowered temperature continuously self-expand to reduce the pressure and lower the temperature in the transfer passage, guiding the compressed air to a terminal expansion spraying/spreading position, The compressed air is directly sprayed to the body surface of the user to spread hot air layer and perform the processes of final expansion, heat absorption and temperature lowering. Accordingly, double cooling effects are achieved.

A waterproof wearable heated cape blanket designed for portability and operated by rechargeable battery pack for heated use outdoors and indoors. The cape blanket comes in a variety of sizes and colors. It is rectangular and about 72 inches or 1.829 meters in length, and about 50 inches or 1.27 meters high, but can be constructed in larger dimensions. It can be constructed from a variety of fabrics and materials. When folded an attached strap is visible and provides a grip surface so that the user can transport the blanket. The weight of the is determined by its size, but easily provides for portability by hand.
