  • Base capacitance compensation for a touchpad sensor
    Patent number: 8115750
    Abstract: For a compensation to the sensed capacitive values of a touchpad sensor, the variance profile of the base capacitance or the sensed capacitive values of the traces in the touchpad sensor is determined, and then a firmware operation based on the variance profile is carried out to modify the sensed capacitive values or the position value when an object touches on the touchpad sensor, such that the touchpad sensor operates as a symmetrical touchpad sensor does.

  • Multi-functional touchpad controller for automobile
    Publication number: 20070185631
    Abstract: A touchpad has a smart man-machine interface. Through a computer system in an automobile, the smart man-machine interface controls systems and multimedia equipments in the automobile, such as an air conditioner and an audio/video player. The interface provides several control modes, such as to control with a keypad, with a writing pad or with a mouse. And the computer system can be connected with a few sets of the touchpad and a display through wire lines or wireless connections.

  • Method for functioning a mouse Zx scroll with a standard mouse driver
    Publication number: 20070171203
    Abstract: In a method for functioning a mouse Zx scroll with a standard mouse driver, a pair of middle-button signals of a mouse are generated by a standard mouse driver of Microsoft to sandwich a horizontal movement amount signal when scrolling a horizontal scroll bar of a window by a Zx mechanism of the mouse. Since the horizontal scroll bar is operated only by the standard mouse driver of Microsoft, there is no need of additional or specific mouse driver for the Zx function of a mouse.

  • Method and device for scroll bar control on a touchpad having programmed sections
    Publication number: 20070075984
    Abstract: A scrolling region is selected on a touchpad and defined several sections each of which corresponding to a displacement signal in a specific direction, such that by touching on the programmed sections to trigger the respective displacement signals, a scroll bar on a window becomes more easily to control for scrolling in desired direction with desired displacement.
