  • Publication number: 20190204979
    Abstract: A device includes a touch and pressure sensitive screen having touch pressure sensors and a controller. The controller acquires touch pressure data from the plurality of touch pressure sensors. For each touch pressure sensor, the controller determines whether the touch pressure data from that touch pressure sensor is indicative of abnormal operation of that touch pressure sensor. Where no abnormal operation is indicated, the controller sums the touch pressure data from each of the touch pressure sensors to produce a touch pressure output. Where abnormal operation is indicated, the controller sums the touch pressure data from each of the touch pressure sensors and multiply the sum by a correction factor to produce the touch pressure output.

  • Publication number: 20190208240
    Abstract: A channel stream is received and demultiplexed into a video packetized elementary stream (PES), audio packetized elementary stream (PES), and program clock reference (PCR). Indexing circuitry stores the video PES and the audio PES in a buffer, locates a presentation time stamp (PTS) in the video PES and stores that PTS in the buffer, locates a start of each group of pictures (GOP) in the video PES and stores those locations in the buffer, and locates a PTS in the audio PES and stores that PTS in the buffer. Control circuitry empties the buffer of an oldest GOP in the video PES if the PCR is greater than the PTS of a second oldest GOP stored in the buffer, and empties the buffer of each PES packet of the audio PES that has a PTS that is less than the PTS of the oldest GOP stored.

  • Publication number: 20190199986
    Abstract: A light projection system includes a light module emitting a light beam and a movable mirror reflecting the light beam toward a surface. A graphics processing unit processes video data to compensate for a response of the light module. The response is an optical power of the light beam produced by the light module for a given forward current through the light module. A light source driver controls the light module as a function of the processed video data. Colors of the images from the video data produced on the surface by the light beam would otherwise not look as they are intended to look due to changing of the response of the light module, but the processing of the video data alters the video data such that the colors of the images from the video data produced on the surface look as they are intended to look.

  • Patent number: 10331530
    Abstract: Embodiments of the circuits described include a method wherein at least one command signal is activated. The activation of the at least one command signal causes a request to a testing circuit of a memory array to enter a memory test mode. The requested memory test mode permits at least part of the memory array to be read. In response to activation of the at least one command signal, a test control circuit initiates an overwrite sequence to overwrite the data stored in the memory array. The test control circuit enables the memory test mode once the overwrite sequence has been completed.

  • Patent number: 10334168
    Abstract: A method determines a movement of an apparatus between capturing first and second images. The method includes testing model hypotheses of the movement by for example a RANSAC algorithm, operating on a set of first points in the first image and assumed corresponding second points in the second image to deliver the best model hypothesis. The testing includes, for each first point, calculating a corresponding estimated point using the tested model hypothesis, determining the back-projection error between the estimated point and the second point in the second image, and comparing each back projection error with a threshold. The testing comprises for each first point, determining a correction term based on an estimation of the depth of the first point in the first image and an estimation of the movement between the first and second images, and determining the threshold associated with the first point by using said correction term.
