摘要:
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.

An apparatus comprises a case, one or more capacitive touchpads mounted on the case for serving as the input interface of the apparatus, and a microprocessor within the case connected to the capacitive touchpads. Each of the capacitive pads generates a signal representative of capacitance change in response to a touch thereon, and the microprocessor determines the displacement, moving speed, relative position, or continuing and discontinuing time of the touch from the signal representative of capacitance change, to accordingly generate corresponding output as a button, Z-axis or scrolling signal.

A mode switch apparatus for an optical mouse comprises a capacitive touchpad mounted on a housing of the optical mouse, and a microprocessor connected to the capacitive touchpad. When a user's hand touches or leaves the capacitive touchpad, a signal representative of capacitance change is generated in response thereto, and the microprocessor switches the optical mouse from a first mode to a second mode, or from the second mode to the first mode, in response to the signal representative of capacitance change.
摘要:
In a capacitive touchpad, a plurality of sensing zones are defined, and a controller is connected with a plurality of scan lines for sensing a movement of an object slipping on the plurality of sensing zones, wherein at least one of the plurality of scan lines is connected to at least two of the plurality of sensing zones. The distance, speed and direction of the movement are determined by detecting the object on the touchpad at two positions upon two scans, and thereby the control of a scroll bar is accomplished. The capacitive touchpad is applied for a Z-axis arrangement on a mouse and a scroll arrangement on a keyboard.

A capacitive touchpad integrated with key and handwriting functions is provided for operation in key, handwriting and mouse modes. Several regions are defined on the panel of the touchpad and have several patterns printed thereon for the operation modes thereby. In the key mode, the key patterns among the printed patterns simulate a keyboard. In the handwriting mode, the handwriting region among the defined regions serves to handwriting input. In the mouse mode, the defined regions provide a cursor moving region and a horizontal and vertical scroll bars for input operations.

For power saving, a structure of a capacitive touchpad comprises a soft board having a bottom surface with a first conductor thereon, a printed circuit board having a top surface with a second conductor thereon, a flexible insulator between the soft board and printed circuit board, and a control circuit having an I/O port connected to the second conductor, such that a pressing on the soft board may move the first conductor down to contact the second conductor to thereby generate a voltage change signal present on the I/O port, causing the control circuit to wake up the capacitive touchpad.
摘要:
A capacitive touchpad provides operational modes including key input, graphical input, handwriting input, and mouse control. The touchpad comprises a panel having several programmed regions thereon, several patterns in the regions are programmed for the operational modes, and a pattern on the panel is programmed as a mode switch to switch the touchpad between the operational modes. In the graphical input mode, the regions include a graphical input region for graphical input. In the key input mode, the patterns include ones for keys to simulate a keyboard. In the handwriting input mode, the regions include a handwriting region for handwriting input. In the mouse control mode, the regions include a cursor control region as well as horizontal and vertical scroll regions.
摘要:
A capacitive touchpad comprises a membrane and a printed circuit board combined together. The membrane comprises an X trace and a Y trace with an insulator layer inserted therebetween, and the printed circuit board has connection pads on a top side of a substrate that are electrically connected to the X and Y traces. The printed circuit board further comprises vias connected between the connection pads and a conductor layer on the bottom side of the substrate. To form the capacitive touchpad, the membrane and printed circuit board are individually produced in advance, and then combined together. Alternatively, the membrane is printed on the printed circuit board.
