摘要： Touch-screen controllers, particularly those in mobile telephones, are prone to erratic behavior when the mobile telephone is plugged into devices, such as AC power adapters, that create electrical noise. To more intelligently mitigate noise in these and other electronic devices that include capacitive touch-screen displays, the present inventors devised, among other things, a touch-screen controller that measures noise level in the touch-screen display and increases its drive voltage only when necessary to exceed the measured noise level, thereby reducing the chance of noise signals being misinterpreted as touch events while also reducing power consumption over prior techniques. Moreover, for electronic devices that include radio receivers, intelligently increasing the touch-screen voltages based on measured noise, avoids the sensitivity-reduction (desense) issues that providing constant higher operating voltage creates.

摘要： A touch sensor integrated with a keyboard spacebar. A touchpad zone can be defined on a portion of a planar surface of a spacebar. The touchpad zone can be configured to detect movement of a human appendage across the touchpad zone, or above the touchpad zone, and generate a corresponding signal from the keyboard that causes corresponding movement of a cursor presented on a display. In another embodiment, a touchpad can be positioned over the spacebar. The touchpad can be slidably engaged to the keyboard to facilitate user positioning of the touchpad over a desired portion of the spacebar.

摘要： A method and apparatus for activating a function of the electronic device is disclosed herewith. The method includes detecting a first input by a motion sensor. Further, the method activates a touch sensor of the electronic device in response to detecting the first input. The method then detects a second input by the motion sensor within a predetermined time period from the first input. Next, the method determines, in response to detecting the second input, whether contact has occurred at the touch sensor and activates a function of the electronic device in response to determining that contact has occurred at the touch sensor when the second input is detected.

摘要： Touch sensor panels (104) have 2-D periodic arrangements of electrodes (304) connected together forming a plurality of horizontal and vertical logical lines (506, 514) for measuring X-Y coordinates of a user's touch. Electrodes forming the horizontal logical lines are interleaved with electrodes forming the vertical logical lines. Each of the vertical and horizontal logical lines includes multiple tracks (502, 504, 510, 512).

摘要： A circuit (800) for controlling at least one piezoelectric actuator (142) includes a piezoelectric drive circuit (802) that generates unidirectional voltage drive signal, also referred to as Vout, at node (804). The piezoelectric actuator drive circuit (802) includes a boost switcher circuit or charging circuit (806), a buck switcher circuit or pulsed current sink discharge circuit (808) and a control signal generating circuit (810) that receives an input control signal (812) from, for example, a keyboard processor or other suitable processor (604) indicating that the device has requested generation of haptic feedback utilizing the piezoelectric actuator (142). The control signal generating circuit (810) provides at least two pulse-with-modulated control signals, one to control the charging circuit and one to control the discharging circuit to produce the unidirectional voltage drive signal, that in one example is a raised cosine drive signal (904).
