  • Patent number: 10162465
    Abstract: A method is performed at a touch sensing system that includes a two-dimensional capacitive sense array. The process measures the capacitance of the capacitive sensors, and identifies a first sensor whose measured capacitance is a local peak. The local peak is within a local rectangular array. The process computes column sums for each column of the rectangular array and determines whether to apply a smoothing algorithm. When the smoothing algorithm is not applied, the process computes an x-coordinate of a touch using a plurality of the column sums. When applying the smoothing algorithm, the process computes the x-coordinate of the touch as an average of two x-coordinate calculations. Each of the two x-coordinate calculations conditionally performs a horizontal shift of the local rectangular array based on comparing the peak measured capacitance to an adjacent measured capacitance and computes a respective x-coordinate using a respective plurality of the column sums.

  • Patent number: 10163403
    Abstract: A system may produce images including narrow-bandwidth colors. One or more sets of the narrow-bandwidth colors may be selected to be interpreted as substantially a same color by a user. The system may include a light source configured to produce the narrow-bandwidth colors, and/or narrow-passband filters may create narrow-bandwidth colors from light emitted by broad-spectrum light sources or color sources. Spatial and/or time multiplexing may be used to create separate narrow-bandwidth colors interpreted as substantially a same color by the user. For example, the light source and/or the narrow-passband filter elements may be adjustable and may alternate between emission of two or more narrow-bandwidth colors. A viewing device may include filters allowing the user to selectively filter the narrow-bandwidth colors. The user may filter the narrow-bandwidth colors to separate a stereoscopic image pair, to view a user-specific image, to view desired content obfuscated by an obfuscating image, and/or the like.
