A secondary power source system, includes a first unit receiving a primary power input and restricting a current used for charging to a predetermined amount, a second unit including a device providing capacitance, receiving a first output from the first unit with restricted current, a third unit generating a second output of a certain voltage, and a fourth unit performing a logical OR operation with the primary power input, first output from the first unit and second output from the second unit, to generate a single third output of a certain voltage.

An energy-reclamation apparatus of the present invention including at least a supercapacitor element connected with a charging source and a controlled circuit. After the supercapacitor element is charged to the potential of the charging source, the supercapacitor element and the charging source will work in series to conduct a repetitive polarity reversal of the supercapacitor element through a controlled circuit. As the supercapacitor element discharges, it is reversely charged concurrently. In other words, while the voltage of the supercapacitor element is decreasing on the side, a negative potential is complementarily developing on the other side. By repeatedly reversing the polarity of the supercapacitor element, more energy from the serially connected charging source can be reclaimed and reused.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To avoid theft and tampering of the portable electrical energy storage devices, by default, each portable electrical energy storage device is locked in and operably connected to the vehicle to which it provides power unless the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as that in a service center. Once within the vicinity of a collection, charging and distribution machine or other authorized external device a locking mechanism in the vehicle or within the portable electrical energy storage device unlocks and allows the portable electrical energy storage device to be exchanged or serviced.

The present invention concerns electrode materials capable of redox reactions by electrons and alkaline ions exchange with an electrolyte. The applications are in the field of primary (batteries) or secondary electrochemical generators, super capacitors and light modulating system of the super capacitor type.

The present invention relates to a supercapacitor, also known as an electrical double-layer capacitor or ultracapacitor, having electrode material comprising single-wall carbon nanotubes. The carbon nanotubes can be derivatized with functional groups. The electrode material is made by preparing a polymer-nanotube suspension comprising polymer and nanotubes, forming the polymer-nanotube suspension into a polymer-nanotube composite of the desired form, carbonizing the polymer-nanotube composite to form a carbonaceous polymer-nanotube material, and activating the material. The supercapacitor includes electrode material comprising activated carbonaceous polymer-nanotube material in contact with current collectors and permeated with an electrolyte, which may be either fluid or solid. In the case of a fluid or compressible electrolyte, an electrolyte-permeable separator or spacer is interposed between the electrodes to keep the electrodes from shorting. The supercapacitor made with electrodes comprising underivatized single-wall carbon nanotubes and polymer that has been carbonized and activated appears to operate as a non-Faradaic supercapacitor.

The present invention provides an electrically conductive electrode comprising particles of an electroactive material and a conductive graphene polymer binder that bonds multiple particles of the electroactive material together, wherein the binder is in an amount of from 0.01% to 90% by weight based on the total electrode weight. Also provided are (a) a precursor solution or suspension to the graphene polymer binder for the electrode; (b) a paste containing electroactive particles and a graphene polymer dispersed in a liquid; (c) a method of producing the electrode from the precursor paste; and (d) an electrochemical cell (a battery or supercapacitor) containing such an electrode.

Wireless game controller can provide variable resistance during strength training exercise and is coupled with off the shelf video gaming system such as Nintendo WII or personal computer by bluetooth or WiFI connection. The resistance is provided by a motor / generator. Electrical recuperation occurs between eccentric and concentric steps of the exercise, electrical energy is stored in a super capacitor between the steps. Video gaming system is configurable to run exercise software that provide reinforcing game experience, coaching, and physical therapy to the user. Exercise software tracks user's pose using fiduciary marks on the controller and data from 3d accelerometer embedded in the controller. The resistance is computed as a function of one or more the following: exercise type, position, velocity, user profile, and repetition number.
