  • Patent number: 11181989
    Abstract: A method performed by a system is provided, wherein the system includes a touch IC executing touch detection and an external processor, which is different from the touch IC and which may include a touch IC support firmware. The system includes a sensor electrode group connected to the touch IC; and a first bus connecting the touch IC with the external processor. The touch IC generates frame data indicative of a detection level of each of two-dimensional positions in the sensor electrode group, and supplies the frame data to the external processor via the first bus. The external processor feeds determination data resulting from performing predetermined processing on the frame data back to the touch IC, and the touch IC performs an operation based on the determination data. Thus, the touch IC can utilize the processing results of the external processor.

  • Patent number: 11169696
    Abstract: Methods and systems are provided for generating, rendering, manipulating (e.g., slicing), and communicating stroke objects that form ink data. In a method of generating a stroke object, pen event data indicative of pen down, pen movement, and pen up events are sequentially received to generate point objects that collectively form a stroke object. The point objects serve as control points for interpolating curve segments. Further, a start parameter indicative of a start point within a starting curve segment of the curve segments at which display of the stroke object starts, and an end parameter indicative of an end point within an ending curve segment of at which display of the stroke object ends, are generated for the stroke object. When rendering the stroke object, a system limits display of the stroke object to a range bound by the start and end parameters, as opposed to displaying the entire stroke object.
