    摘要: A proximity sensor system includes a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed.

    摘要: An apparatus for touchpad-based scroll control and method for scroll control comprising a data packet processor working in conjunction with a touchpad. A scroll zone, having a central axis, is defined on the touchpad. After detecting a user running a finger on the touchpad in a direction substantially parallel to an axis running the length of the scroll zone, the processor software sends scrolling messages to the operating system or application that owns an active window. The packet processing software is configured to not scroll on motions that are not substantially parallel to the axis of the scroll zone, thereby avoiding unwanted interference with normal program function, and also stops scrolling when the user lifts the scroll-activating finger or moves it in direction substantially perpendicular to the scroll zone.
