  • Patent number: 10963098
    Abstract: This relates to methods and apparatus for estimating an object profile to improve accuracy of touch sensor panel input (e.g., reducing input position wobble for a stylus or finger translating on a surface over and between electrodes of a touch sensor panel). In some examples, the object profile estimation can begin with an initial profile estimate that can allow the object profile estimation to converge for a large range of possible input object sizes, shapes, distances, and/or orientations. The object profile information can use data from multiple frames of data acquisition as well as multiple pixels in the panel to construct the object profile estimate based on the input measurement. Specifically, the object profile can be estimated by measuring the object at various positions relative to touch pixels or nodes and gaps between touch pixels or nodes over multiple frames of sensor data and combining the measurement data of the multiple frames.

  • Patent number: 8274429
    Abstract: Computer-implemented systems and methods are provided for source-localization and self-calibration for an array of antenna elements. In one implementation, a method is provided that includes estimating directions of arrival of a plurality of signals received by a plurality of antenna elements of the array of antenna elements and identifying a target signal from among the plurality of received signals. The method may also include estimating complex gain of each of the plurality of antenna elements in a direction of arrival of the identified target signal, wherein the estimation of the complex gain of each the plurality of antenna elements is performed after estimating the directions of arrival of signals received by the plurality of antenna elements.
