    Abstract: A circuit includes a force driver configured to apply a force signal to a force node associated with a mutual capacitance to be sensed. A sensing circuit receives a sense signal from a sense node associated with said mutual capacitance to be sensed. The sensing circuit operates to generate an output signal indicative of the sensed mutual capacitance. A control circuit controls generation of the force signal to alternate between at least two different frequencies and generate said output signal for each half cycle of the force signal.

    Abstract: A capacitive sensing system includes a capacitive sensing panel with drive lines and sense lines. Each drive line includes a drive circuit. A code generator operates to generate modulation codes. A drive controller generates drive signals wherein each drive signal is modulated by one of the modulation codes. The generated drive signals are applied to the drive lines through the drive circuits. The drive controller operates to simultaneously generate the drive signals for application to a corresponding group of drive lines during a drive period. Separate groups of drive lines are sequentially driven with the same drive signals during drive periods that only partially overlap.

    Abstract: Embodiments of the present disclosure are directed to techniques for adjusting the amplitude of a digital audio signal in the frequency domain to control the perceived loudness of the audio signal at a desired level. In one embodiment, a method first adjusts the audio signal to a desired loudness level by applying an adaptive wideband gain and thereafter a multi-band compression is applied to further reduce a dynamic range of the audio signal, and noise analysis and temporal masking operations are also performed to provide a pleasant sound for a listener or listeners.

    Abstract: A microelectronic short circuit detection module is disclosed that locates and distinguishes among different types of short circuits in touch screen panels. Individual short circuit detection circuits are coupled to force and sense lines throughout a wire matrix within the touch screen. If the line is shorted to a neighboring line or any other line carrying an opposite logic state, its logic state will be corrupted by the short and will be held at a value opposite that of the intended input signal. Comparing the input and the output therefore provides an indicator of a short circuit to another force or sense line in the wire matrix. A pair of pull up/down stages is engaged to detect whether the short is coupled to power or ground. A threshold resistor can be varied to adjust detection sensitivity. By conducting a serial test, matrix coordinates of the short circuit can be identified.

    Abstract: A video display includes a video display panel and a video display drive circuit configured to control a display on condition. A touch screen includes a touch screen panel (mounted on top of the video display panel) and a touch panel control and sense circuit configured to operate the touch screen panel in a self-capacitance mode. The touch panel control and sense circuit includes sense drive circuits configured to generate sense drive signals for application to sense lines of the touch screen panel. A controller controls actuation of the sense drive circuits so that the sense drive signals are synchronized to the display on condition. In an implementation, the leading edges of the sense drive signals are synchronized to the display on condition. In another implementation, a window is synchronized to the display on condition and the leading edges of the sense drive signals exhibit jitter within the window.
