    Abstract: A touch screen controller provides a host interrupt to a host device operating in a low power consumption mode. The touch screen controller uses gesture templates to detect gestures input via a touch screen. Each gesture template is associated with an event identifier, and each event identifier is associated an application. Each gesture template includes a template identifier, a matching threshold, a criterion, and coordinates corresponding to locations on the touch screen panel. If at least one of the coordinates corresponding to a gesture input via the touch screen satisfies the criterion included in a particular gesture template, the touch screen controller provides a host interrupt with the event identifier corresponding to that gesture template to the host device. In response to receiving the host interrupt with the event identifier, the host device exits the low power consumption mode and opens the application associated with the event identifier.

    Abstract: An electronic device includes a processor that acquires touch data values corresponding to different locations of a touch display, and identifies an island in the touch data that has touch data values acquired from adjacent locations of the touch display that indicate a potential touch. A first area of the island is determined from touch data values that exceed a first threshold value, and a second area of the island is determined from touch data values that exceed a second threshold value. If the first area is less than a multiple of the second area, coordinates of a location of the island are determined from the touch data values indicating the potential touch. If the first area is at least the multiple of the second area, coordinates of a location of the island are determined from the touch data values indicating the potential touch that exceed a third threshold value.

    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.

    Abstract: A digital video rescaling system is provided. The system includes an image data input configured to receive input support pixels y1 to yn and a sharpness control module configured to generate a sharpness control parameter Kshp. The system further includes an interpolated pixel generator configured to use an adaptive interpolation kernel to generate an interpolated pixel ys based on the input support pixels, and adjust a sharpness of the interpolated pixel ys based at least partly upon the sharpness control parameter Kshp. The system also includes a de-ringing control unit to adjust the ringing effect of the interpolated pixel based on a local image feature Kfreq, and an output module configured to output the adjusted interpolated pixel for display.
