A touch scroll mouse with orientation sensation comprises a touchpad providing a scroll bar function. The touchpad comprising a plurality of orientation structures, these orientation structures including barriers, protuberant or concave lump structures, protuberant transverse structures or transverse nicks, supplying the users to tell if their finger touch the auto-scrolling regions or determine their slide distance and direction.

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.
摘要:
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.
摘要:
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.

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.

摘要:
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.
