    Abstract: An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events on a surface. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. Touch events on the surface disturb the optical beams received by the detectors. Based on the disturbed beams, a map of the touch activity on the surface is generated. Touch characteristics and touch types for each touch event are determined from the map. By applying the touch characteristics and touch types to contextual information, a machine learned model, or a set of predefined rules, touches can be classified as wanted or unwanted touch events. Unwanted touch events may be ignored to improve user experience.

    Abstract: Improved sensing can include modified sampling and/or processing to improve performance against noise due to environmental variations and interference. In some examples, improved interference rejection can be achieved by sampling a sensor multiple times during settled periods. In some examples, the excitation signal and sampling window can be dynamically adjusted to satisfy drift and/or interference specifications based on various operating conditions or the operating environment. In some examples, drift performance can be traded off to improve interference performance. In some examples, improved immunity to environmental variations can be achieved by equalizing sensor outputs in accordance with characterization of the sensing system. In some examples, improved performance can be achieved by sampling the sensor continuously and using an optimized window function to improve performance against noise.

  • Patent number: 10810404
    Abstract: Embodiments relate to bioimpedence-based spoof detection in an optical biometric reader. For example, embodiments operate in context of a biometric reader having a platen integrated with substantially transparent bioimpedance source and receiver electrodes covered by a substantially transparent protective layer. A multi-frequency input signal can be injected from the source electrode into a purported skin site (through the protective layer), so that a response signal is received by the receiver electrode. The response signal is interrogated to formulate a dispersive bioimpedance response of the purported skin site to the input signal over multiple frequencies. A biometric spoof determination can then be made according to the dispersive bioimpedance response. The spoof determination can be used for spoof detection, presence detection, and/or other functions.

  • Patent number: 10795491
    Abstract: A position detecting device obtains information from a stylus when the stylus moves at high speed, while removing influences of noise. The position detecting device includes a differential amplification circuit that amplifies and outputs a difference in a signal at a first terminal and a signal at a second terminal, and a selection circuit that selects at least a first electrode of a sensor, connects at least the first electrode to the first terminal of the differential amplification circuit, selects at least a second electrode of the sensor, and connects at least the second electrode to the second terminal of the differential amplification circuit. The selection circuit selects electrodes separated by a first interval in a period in which a position indicated by the stylus is detected, and selects electrodes separated by a second interval that is shorter than the first interval in a period in which data is detected.
