Compression of venous tissue enables improved blood flow in the feet. For example, nitinol wire wrapped around a curved footbed is electrically heated and thus shrinks forcing the wire on the top of the footbed into the bottom of the foot. The wire, or group of wires, is successively withdrawn and re-pressed against the bottom of the foot from toe to heel. Athletic recovery and treatment of various medical conditions may be achieved, for example restless leg syndrome, edema, plantar fasciitis, deep vein thrombosis, pulmonary embolism, venous insufficiency, wound care, and the like.

An indicator for a heated article of footwear that includes an outer shell and a removable inner liner is described. The inner liner includes a heating system with an indicator disposed on a forefoot region of the inner liner. The heating system is integrated within the inner liner and is removable with the inner liner from the outer shell. A viewing window is disposed on the outer shell at a location corresponding to the indicator located on the inner liner. With this arrangement, the status condition of the heating system on the inner liner may be communicated to a wearer of the article through the viewing window from within the interior of the article.

A vehicle including a system for transferring energy between on-board vehicle components and/or between on-board and external components. The vehicle is configured to heat various components through induction to provide comfort to the rider and/or to transfer energy for charging one or more vehicle components.

In an embodiment, a method for heating a personal device using a wirelessly-powered heating device includes: wirelessly receiving power with a receiving coil of the wirelessly-powered heating device, the receiving coil located inside the personal device, where the receiving coil is coupled to a capacitor of the wirelessly-powered heating device to form a receiver resonant tank; and heating the personal device with heat produced by a resistance of the receiving coil, where the receiving coil functions as a receiver antenna and as a heat producing element.

A heated article comprises a circuit board; one or more batteries electrically connected to the circuit board; a flexible heating element electrically connected to the circuit board; a control switch electrically connected to the circuit board and configured to selectively adjust the heating element; and circuitry configured to charge the one or more batteries.

Provided are a smart shoe, a smart device and a method for switching functional area. The smart shoe includes a shoe body and a smart device provided on a surface of the shoe body. The smart device includes a processing unit, a locating unit, a communication unit, a solar energy receiving unit and a power supply unit. The locating unit is configured to acquire current position information of the smart shoe and send it to the processing unit. The processing unit sends the received position information to a user terminal or a remote server via the communication unit. The solar energy receiving unit is configured to receive solar energy and converting it into electrical energy which is transferred to the power supply unit. The power supply unit is connected with individual functional units of the smart device to supply the electrical energy to the smart device.

A ski boot (1) includes a base frame (2) for receiving a foot of a skier; a rigid sole (3) connected to the base frame (2); a shaft (4) for receiving a lower leg part of the skier, the shaft (4) being angularly variably connected to the base frame (2); and a traction element (12). The traction element is attached to the sole (3) and/or in a toe area of the base frame (2) and extends from there to a heel area of the sole (3). In the heel area, the traction element (12) is deflected towards the shaft (4) and is then attached to the shaft (4). By inclining the shaft (4) towards a toe region, the traction element (12) can be tensioned and, in particular, traction can be exerted on the sole (3) and/or the toe region.

The disclosure relates to a smart footwear that is capable to maintain the temperature within the set range using Peltier modules (10.i), that are additionally used for energy harvesting. The footwear is equipped with plurality of inner temperature sensors (20.j). Outer temperature is recorded by one or more sensors (30.k). Data processing unit (70) executes a program for heating/cooling and energy harvesting, where only i-th Peltier module is used in time for heating/cooling and other modules (10.1) where i?l for energy harvesting. In the preferred embodiment, the index i is changed consecutively to be 1->2->3-> . . . ->(N?1)->N with time period D that defines a duty cycle of each i-th Peltier module, and with the adjustable time period D1 before each new cycle 1->2->3-> . . . ->(N?1)->N, while all Peltier modules are in energy harvesting mode. Time periods D and D1 are used to regulate delivered power for heating/cooling.
