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).

摘要： The invention concerns a method (200) and a system (100) for ensuring audio safety in an audio device (110). The system includes a processor (112), a sensor (116), an analog safety circuit (114) and a first feedback loop (117). The processor is programmed to output an acoustic output signal (310, 410), the sensor monitors the acoustic output signal and the analog safety circuit is coupled to an output of the processor. The first feedback loop feeds the monitored acoustic signal from the sensor to the analog safety circuit. The analog safety circuit adjusts from a first level (312, 412) to a second level (316, 414) the acoustic output signal when the acoustic output signal exceeds a predetermined safety threshold (314, 420) such that the audio device has an output capacity that is capable of driving a sound pressure level of the acoustic output signal above the predetermined safety threshold.

摘要： A multimodal electronic device (100) includes a shutter enabled dynamic keypad for presenting one of a plurality of keypad configurations to a user. Each keypad configuration, which is presented by an optical shutter (204) that opens or closes windows or shutters that are geometrically configured as alphanumeric or device keys or symbols. Each keypad configuration, in one embodiment, is limited to those needed for the particular mode of operation of the device (100). The optical shutter (204) is a low-resolution display that presents user actuation targets to a user in a low-resolution key area. As each mode of the device changes, the corresponding keypad configuration presented changes accordingly.

摘要： Disclosed is a method (50) and device (100) for providing an equi-potential touch screen. The method can include: providing (52) a capacitive touch screen including transmit electrodes and receive electrodes combined to form a grid structure configured to provide capacitive signals that allow position of touch to be resolved; and driving (54) a substantially central transmit electrode with equi-potential connection points. The method (50) and device (100) provide a touch screen device which allows drive lines to be split on either side of the touch screen device, while being highly linear. For example, the frame area surrounding the touch screen can be made narrower or thinner, for minimal real estate and optimizing design layout.

摘要： A method for dynamically controlling audio signal gain in a communication device starts with determining a level of an input audio signal. The level is then mapped against a table of predetermined corresponding gain targets to determine an appropriate gain target for that level. The gain targets are then applied to the audio signal, which is then output. The invention is particularly suited to speakerphone operation in a communication device, wherein the gain targets provide compression, expansion or limiting so that distant speakers can be heard clearly.
