Patents by Inventor Wei-Chuan Wang

Wei-Chuan Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7916122
    Abstract: The present invention relates to a roller mechanism for generating a plurality of control signals, for example to scroll an image on a computer display in multiple directions. The roller mechanism has a carriage, and a roller rotatable within the carrier. The roller can drive an encoding unit to output the control signal. The carriage has a coupling portion, and the coupling portion is pivoted to a bottom support. Thus the roller and the carriage are turnable relative to the coupling portion in a fan-shaped movement while the roller is also being rotated within the carriage.
    Type: Grant

  • Patent number: 7295185
    Abstract: A multi-directional roller assembly for an input device includes a housing and a carrier supported within the housing. The carrier has a roller that can be rotated so as to scroll an image vertically on a display. The carrier can also be tilted left and right so as to execute a command or scroll the image on the display in a horizontal direction.

  • Patent number: 7012594
    Abstract: A Z-axis device for an input device has a rotatable roller having a first side and a second side, the second side of the roller having a plurality of grooves. The Z-axis device also has a support mechanism that positions the roller for reciprocating pivoting movement, a first axle extending from the first side of the roller and supported by the support mechanism, and a second axle extending from the second side of the roller and supported by the support mechanism. The second axle has a resilient element coupled thereto, with the resilient element constantly engaging one of the grooves, and engaging different grooves as the roller is rotated.

  • Patent number: 6967645
    Abstract: An encoder device coupled to a roller or “scroll wheel” includes a mechanism to convert a rotating movement of the roller into a reciprocating movement that causes intermittent electrical conduction between two metal contacts so as to output an intermittent electrical signal indicative of roller movement without continuous power consumption.

  • Patent number: 6176730
    Abstract: An electrical connection cable manufacturing method includes the steps of (1) providing a first insulator defining a plurality of channels for receiving and retaining conductive pins, a tail section of each pin having a sharpened edge; (2) providing a second insulator defining a plurality of channels each receiving a leading end of an electrical wire, each channel having a slot communicating therewith; and (3) bringing the first and second insulators toward each other whereby the tail ends of the pins are inserted into the corresponding slots of the channels of the second insulator and the sharpened edge of each pin cuts through an insulative sheath of the wire to electrically engage a conductive core thereof. An electrical connection cable manufactured from the above-described steps comprises a positive displacement connection between the sharpened edge of the conductive pin and the conductive core of the wire thus soldering is not required.
