    Abstract: The present invention provides a charging device for a button/coin cell rechargeable lithium ion battery. A receiving inductor coil receives energy from a transmitting inductor coil which is passed to a wireless charging receiving circuit which is in electrical communication with the receiving inductor coil. The wireless charging receiving circuit communicates with a charging control circuit, a voltage regulation circuit, and a battery protection circuit in electrical communication with one another. The voltage regulation circuit includes a 1.8 V to 3.3 V constant voltage output regulator circuit to maintain a constant voltage output in loading currents ranging from approximately 10 μA to approximately 300 mA.

    Abstract: An electronically-activated, self-molding and re-shapeable load-bearing support structure system is provided that includes a first composite structure. The first composite structure includes a first layer of a first thermally-responsive polymer; one or more first heating elements positioned adjacent to the first layer on a first heating element side; a second layer of the first thermally-responsive polymer positioned adjacent to the first heating elements on a second heating element side; a temperature sensor communicating with at least the first layer or the second layer of the first thermally-responsive polymer; one or more electrical connectors electrically communicating with the heating elements; and an electrical controller detachably connectable to at least one of the electrical connectors of the composite for providing an electrical current to the heating elements. A method of molding the load-bearing support structure system is also provided.
