A wearable accessory capable of communicating data to actuators or from sensors is disclosed. The wearable accessory includes a conductor wire disposed in a moldable medium according to a predetermined pattern, the moldable medium being an electrically insulating material, the conductor wire terminating at an input and an output.

A heat transfer system may include a heat transfer machine adapted to thermally couple to an heat transfer pack housed within an heat transfer device and transfer heat from the heat transfer pack using a power supply. The heat transfer device may include a housing and a heat transfer pack. The heat transfer pack may be adapted to thermally couple to the heat transfer machine, transfer heat to the heat transfer machine while thermally coupled to the heat transfer machine, and transfer heat from a mammal's skin when the heat transfer device is in contact with the mammal's skin and uncoupled from the heat transfer machine.

Described herein is a perspiration evaporation device (PED) utilizing an evaporative column having an internal channel that can be secured to a garment or other accessory. As air passes over the top opening internal channel the internal air pressure within the evaporative column is reduced causing evaporated moisture from a user's skin to be drawn up the internal channel and away from the skin resulting in improved evaporation of moisture and a reduction in the core body temperature of a user.

A personal cooling enclosing material comprises a garment body; an air cooling system provided on an outside surface of the garment body, wherein the air cooling system further comprises a receptacle and a coolant contained in the receptacle; and an air circulation system provided on an inside surface of the garment body for drawing original air from an internal space inside the garment body for cooling. The air circulation system is separated from the air cooling system to avoid direct contact of the original air with the coolant of the air cooling system. The air cooling system is in thermal communication with the air circulation system.

An apparatus comprises first and second fabric layers having corresponding and aligned elongated rectangular sections, which are stitched together at one or more periphery seams. A water-permeable compartment is located between the first and second elongated rectangular sections at the respective middle portions the first and second fabric layers. The water-permeable compartment has an elongated rectangular topside section and an elongated rectangular underside section, each having a length that is less than the length of the elongated rectangular sections of the first and second fabric layers. The second fabric layer and water-permeable compartment collectively define an opening at the middle portion of the second fabric layer, wherein the opening is configured to receive a cooling medium or a heating medium. The apparatus provides the option of whether to wet the middle portion of the second fabric layer that is in contact with the neck of a user.
