Appl. No.:

10/726261

Inventors:

Sung Choi - Canyon Country CA, US

International Classification:

H01M004/90
H01M008/20
H01M004/96
H01M004/88

US Classification:

429043000, 429105000, 429044000, 502101000

Abstract:

A bio-implantable electrochemical cell system for active implantable medical devices. In one embodiment, the fuel cell includes an electrode structure consisting of immobilized anode and cathode enzymes deposited on nanostructured high-surface-area metal nanowires or carbon nanotube electrodes. The anode enzyme comprises immobilized glucose oxidase and the cathode enzyme comprises immobilized laccase. Glucose is oxidized at the surface of the anode and oxygen is reduced at the surface of the cathode. The coupled glucose oxidation-oxygen reduction reactions provide a self-generating current source. In another embodiment, the nanowires or carbon nanotubes, along with the adjacent surface anode and cathode electrodes, are coated with immobilized glucose oxidase and immobilized laccase containing biocolloidal substrates, respectively. This results in the precise construction of an enzyme architecture with control at the molecular level, while increasing the reactive surface area and corresponding output power by at least two orders of magnitude.

International Classification:

A63B 6936

US Classification:

473224

Abstract:

A practice golf club aids golf players in improving their stroke by indicating whether or not their swing generates an adequate amount of club head speed. This is achieved by utilizing the centrifugal force generated by a golf swing to actuate a piston located at the head of the golf club. If sufficient club head speed is attained and the piston is displaced a certain amount, a lamp momentarily blinks and an audible "click" can be heard to notify the user that the swing was indeed adequate. The components of the club include a piston, holding ball bearings, a return spring and an electrical circuit which contains a lamp and a ball bearing which is contacted by the piston when the piston is displaced by centrifugal force. The piston produces a second "click" when it is returned and strikes an upper piston chamber wall.
