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 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.

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.
