US Patent:

20030132914, Jul 17, 2003

Filed:

Jan 17, 2002

Appl. No.:

10/051503

Inventors:

Calvin Lee - Novi MI, US

International Classification:

G09G005/08

US Classification:

345/163000

Abstract:

An integrated mouse and pad pointing device is thin and compact that can be built into a laptop computer or other portable computational devices such as a personal data assistant (PDA) or a cell phone with a cursor to replace the cursor control devices such as the touch pad or the pointing stick. This integrated mouse and pad pointing device has a mouse sliding in a slot of a pad plate while the pad plate slides relative to or rotates about a stationary base plate. By sensing the movement of the mouse in the slot relative to the pad plate and the movement of the pad plate relative to the stationary base plate, the movement of the mouse and hence the cursor is determined. This mouse works like a conventional mouse so it is ergonomically easy and accurate to use to control the movement of the cursor. This integrated mouse and pad pointing device with the built-in click buttons in a portable computational device such as a laptop computer allows a convenient operation of controlling the cursor movement and the clicking of the buttons at the same time. A stand-alone version of this device may be plugged in to a desktop computer and will work on any condition.

Calvin Chunliang Lee - Novi MI, US

International Classification:

B32B 3/06

US Classification:

428 99

Abstract:

A suction tape with a large number of miniature vacuum suction cups on one side or both sides is invented here. The suction tapes have many of the advantages of the double-sided adhesive tapes, hook-and-loop (Velcro) tapes, and vacuum suction cups without their disadvantages.

US Classification:

180242, 903903, 180 65245

Abstract:

A vehicle drive system comprising three motor/generators, an engine and an electrical energy storage device. The system is arranged so that two axles can be driven at the same time. Each axle can be driven using power generated by the engine or provided by the electrical energy storage device. The system can also be configured to drive one of axles using mechanical power from the engine.

International Classification:

F03D 7/04

US Classification:

416 44

Abstract:

This invention proposes a cross-flow turbine design with airfoil blades and self-alignment mechanisms. The airfoil blade self-alignment mechanisms rotate the airfoil blades at half of the turbine main shaft's speed and dynamically flip the blades after reaching the windward position to realign the airfoil blades or reset the attack angle of each airfoil blade so that the airfoil blade feathers the fluid flow at the windward position, generates maximum drag force at or near the leeward position, and produces both maximum lift and drag forces in between.
