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.

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.

A capacitive touchpad includes a controller, a plurality of scan lines and a plurality of sensor pads distributed over a one dimensional touch sensor. Each of the sensor pads is connected to the controller by a respective one of the scan lines to transmit a sensed value to the controller. The controller uses the sensed values and the positions of some of the sensor pads in an interpolation to determine the two dimensional coordinates of one or more touched positions. Based on the sensed values, the controller selects one or more of the sensor pads as one or more reference points for the interpolation.

In a gesture detection method for a touch control bar with button and scroll bar functions, according to the present invention, various gestures such as tap, drag and double tap are determined by detecting an object that touches on the touch control bar, leaves from the touch control bar, and moves on the touch control bar.

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.

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.
