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： 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 comprises a plurality of mode based actuators, wherein the plurality of mode based actuators comprises at least a ten-digit keypad actuator set (2000) and a curved scroll device (1903). 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： 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.
