Abstract: In a gesture detection method for a capacitive touchpad, various gesture operations are determined by detecting the touching on the touchpad, leaving from the touchpad, and moving on the touchpad.

Abstract: In a method for window operation on a touchpad, when an object is detected to slide on the touchpad, the position where the object falls down to touch the touchpad is defined as an original point, and a position where the object stops sliding on the touchpad is referred to a relative position, a direction and a difference value are determined upon the original point and the relative position, and a signal is produced according to the direction and the difference value to send to a host to trigger a window operation.

Abstract: In a method for window movement control on a touchpad, the area size of the object sliding on the touchpad is calculated to determine the speed that the touchpad produces a movement signal to control a window such that the greater the area size is, the faster the window scrolls.

Abstract: A touch sensor comprises a plurality of traces in a same sensing layer or in different sensing layers, and the base capacitances of the traces are made uniform by connecting one or more compensation areas to one or more of the traces or selecting the distances between the grounding layer and one or more of the traces. The compensation area and the trace it compensates may or may not in a same layer.

Abstract: In a gesture detection method for a touchpad, various gestures such as tap, drag and double tap are determined by operating an object to touch on the touchpad, leave from the touchpad, and move on the touchpad.

Abstract: In a gesture detection method for a touchpad, according to the present invention, various gestures such as tap, drag and double tap are determined by operating an object to touch on the touchpad, leave from the touchpad, and move on the touchpad.

Abstract: A smart control method for cursor movement using a touchpad comprises detecting the location of an object touched on the touchpad for determining the coordinate information of the object, detecting the movement of the object on the touchpad for generating the location information of the object, and generating a signal representative of moving a cursor if the object is detected to stop moving on and stay on the touchpad for a period longer than a threshold time.

Abstract: In a method for detecting overlapped function area on a touchpad with the overlapped function area overlapped by more than two different function areas, when the overlapped function area is touched by an object, a further function can be correctly performed according to touched duration, touched movement, or a terminal touched area pressed onto the touchpad.

Abstract: A scroll control method using a touchpad comprises predefining a region on a touchpad, whereby a scroll function will be triggered by a landing of an object on the region, and terminated by a leaving of the object from the touchpad. During the scroll function is executed, the moving distance of the object sliding on the touchpad is calculated to determine a corresponding scrolling signal.

Abstract: In an object detection method for a capacitive touchpad, at least one reference time interval is used to distinguish whether a variation of the sensed value on the touchpad is resulted from an operation of an object on the touchpad, actions such as an object touch down to the touchpad, an object lift from the touchpad and an object movement on the touchpad are then determined, and operations corresponding to various gestures are correctly detected.

Abstract: An integrally formed touchpad module comprises a touchpad integrated with peripheral functional buttons and directly attached underneath the equipment case. Therefore, no holes need to be opened on the case and no additional real buttons are required in the touchpad module mechanism. It is thus achieved the goals of integrally formed mechanism, cost reduction, waterproof, anti-dust and good-looking.

Abstract: For supporting two-side operation, a touchpad comprises a sensor, an insulator layer above the sensor for providing an operation area, and a button operation conductor under the sensor to be moved to connect to or approach the sensor for triggering a button function.

Abstract: A touchpad is defined to have a first zone and a second zone, and operated in such a way that a location information of an object is generated when the object is detected to move within the first zone, and a scrolling signal is generated if the object moves into the second zone and stays therewithin for a period longer than a threshold time.

Abstract: A capacitive touchpad with physical key function comprises a soft flexible first conductive layer; a second conductive layer; and a soft flexible insulator layer disposed between the first and the second conductive layers. The insulator layer has at least a through hole for the first conductive layer to connect to the second conductive layer while the touchpad is pressed and cause the voltages on the first or the second conductive layers to change and thus to trigger a predetermined key function.

Abstract: A touch-sense apparatus available for one-dimensional and two-dimensional modes comprises a sensor having a plurality of traces in two directions to sense the position touched by an object to produce a first signal, a two-dimensional coordinate processor to produce a two-dimensional coordinate based on the first signal in the two-dimensional mode, and a coordinate transformer to produce a second signal from the first signal or the two-dimensional coordinate in the one-dimensional mode for a one-dimensional coordinate processor to produce a one-dimensional coordinate in response to the second signal.

Abstract: In a touchpad with single-layered PCB structure, a PCB has a bottom layer with a sensor area and a component area thereon, the sensor area includes two directional traces directly connected to the component area, respectively, and carbon film wires in the sensor area for interconnecting one or more of the directional traces.

Abstract: A storage device with separable data protection comprises a plurality of one-time or multiple-time programmable read-only memory (ROM) blocks, and a protection device having a plurality of protection control areas. The plurality of ROM blocks may be programmed individually at different times, and the plurality of ROM blocks may be then encrypted by the plurality of protection control areas selectively and respectively, after each programming is completed.
