摘要： A method and system for determining a camera-to-display latency of an electronic device (100) having a camera (134) and touch-sensitive display (108) are disclosed. In one example embodiment, the method (500) includes receiving (511) first light (136) at the camera, and essentially simultaneously receiving second light (138) at a first photosensitive structural portion (102, 602). The method (500) further includes detecting (512) a first simulated touch input at the display (108) in response to a first actuation of the first photosensitive structural portion (102, 602), receiving third light (140) at a second photosensitive structural portion (104, 604), the third light being generated based at least indirectly upon the received first light (136), detecting (514) a second simulated touch input at the display (108) as a result of the receiving of the third light (140), and determining the camera-to-display latency based at least indirectly upon the touch inputs (516).

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).
