  • Patent number: 10372265
    Abstract: Touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals, along detection lines across a touch surface. A signal processor operates in a sequence of repetitions to: generate data samples that represent detected signal energy on the actual detection lines; generate based on the data samples, an interpolated sinogram comprising interpolation samples that represent fictitious detection lines which have a desired location on the touch surface; and reconstruct a signal interaction pattern for the touch surface based on the interpolated sinogram. The signal processor implements an error correction to counteract the influence of a change in validity status for a data sample among the data samples, by identifying interpolation samples affected by the change in validity status, and by setting each identified interpolation sample to a value that maintains a relative signal transmission of the fictitious detection line from a former repetition.

  • Patent number: 10318041
    Abstract: A signal processor implements a technique for detecting objects on a panel which transmits signals inside the panel such that the objects are allowed to interact with (e.g. attenuate) the signals by contact with a touch surface of the panel. The signal processor operates to define cells that have a given location on the touch surface and are associated with a respective set of intersecting paths for the signals across the touch surface. The signal processor operates to obtain (90) an output signal from a signal detection arrangement that measures a signal property for each path; process (91) the output signal to obtain an interaction value for each path; and generate (93-95?) a cell value of a selected cell among the cells as either a robust measure of central tendency (e.g. a median) or a minimum/maximum among the interaction values for the intersecting paths. The signal processor determines (97) presence or absence of an object in the selected cell based on the cell value.
