摘要:
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.

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.

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.

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.
摘要:
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.
摘要:
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.
