    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.

    Abstract: A touch screen device is configured with rows of conductors capable of receiving wireless signals from a stylus. When the stylus touches the touch screen, the stylus emits multiple wireless signals in different directions. The conductors receiving the emitted wireless signals provide the signals to circuitry that filters, amplifies, and digitizes the wireless signals, as received at each conductor. The magnitude of each conductor's received wireless signal is computed, and the computed magnitudes are used to determine the location of the stylus on the touch screen surface. The stylus is assumed to be closer to conductors receiving stronger signals than those receiving weaker signals.
