    Abstract: A method of mechanical-to-electrical energy conversion utilizes a mechanical spring (22) in combination with a rapid-action variable inductance magnetic flux switch to convert a spring-loaded mechanical energy into a change in magnetic flux captured by an electrical coil element (32) within the magnetic flux switch. The change in coil inductance and magnetic flux induces a current to flow through the electrical coil in the form of a a pulse of electrical energy that may be stored. The electrical coil (32) is coupled to the mechanical spring (22) so that each time the spring is released, the coil moves with respect to a magnetic core (28) and a change in flux is created. The application of an external mechanical force (such as human locomotion) functions to compress and subsequently "unlock" the mechanical switch, allowing for the electrical energy associated with the application of aperiodic forces to be harvested.

    Abstract: An apparatus providing mechanical-to-electrical energy conversion generates electrical current by moving a conductive fluid in the presence of magnetic field. The motion of the fluid is induced by a mechanical energy source and the generated electrical current is directed to a useful load. The proposed apparatus utilizes a conductive fluid as a "liquid rotor" has substantially different radial velocity distribution than the conventional, prior art solid rotor. The apparatus includes an inverter, controlled by the flow of the conductive fluid, to generate a train of pulses as an output, where the pulses are used by an associated transformer to provide an AC output voltage.

    Abstract: An arrangement for regulating the interior temperature of footwear takes the form of an insole (or midsole) and includes a heat generator and a heat storage and release element. The heat generator may be configured to capture mechanical energy in the form of human locomotion and convert the captured energy into heat. Other types of heat generators may also be used. The heat storage and release element comprises one or more phase change materials that function to absorb generated heat (to keep footwear from overheating), as well as release the stored heat when the ambient temperature of the footwear drops below the transition temperature of the material.

    Abstract: An energy harvesting apparatus is described that utilizes hydraulic actuation and creates a continuous, revolving motion of a chain of energy- producing elements within an energy-producing channel (the channel being in the form of a tube, for example). In particular, the arrangement of the present invention is based upon a specially-designed dual-loop channel topology that allows for efficient conversion of a unidirectional flow of a fluid entering the energy-producing channel into a smooth, continuous revolving motion of a chain of energy-producing elements within the channel.

    Abstract: A closed-loop apparatus for converting mechanical energy into electrical energy utilizes a closed-loop channel including sections of different cross-section (including a first group of sections having a constrained cross-section and a second group sections having an enlarged cross-section). An energy- producing configuration (such as coils and/or electrodes) is formed to surround at least a portion of the channel. A closed-loop chain of energy-producing elements is positioned in channel such that when the chain moves along the channel, the mechanical motion generates electrical energy. The chain is formed to include a set of expandable assemblies that change in dimension as they pass through the different cross-section areas of the channel. An inert liquid is injected into the channel at one or more locations by a mechanical force, resulting in the creation of a pressure-induced force differential that initiates and maintains the movement of the chain with respect to the channel.
