    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.

    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: 10664072
    Abstract: This document describes techniques for, and systems that enable, a multi-stroke smart ink gesture language. The described techniques enable a digital ink user interface that allows a display, that is capable of receiving a digital ink stroke from a passive stylus or an active pen, to receive the digital ink stroke as either a content input or an action input. The digital ink stroke may be determined to be an action input based on proximity to, intersection with, or chronological immediacy to a prior-received digital ink stroke. When multiple digital ink strokes are determined to represent a multi-stroke gesture associated with an action input, the action input is provided to the application, which can then perform the action associated with the action input. The multi-stroke gesture allows users to input both content and actions using the passive stylus or active pen and natural digital inking strokes.

Currents drawn during the active sensor state are substantially constant. During transition, currents decrease from the substantially constant current to a minimum current. During data transfer, currents vary between the substantially constant current and the minimum current. A logical element is configured to monitor the current drawn by the sensor module and, based on variations therein, determine the operating state of the sensor module. A method for using the processor is also disclosed.

  • Patent number: 10635211
    Abstract: A display device includes an input sensing unit. The input sensing unit includes sensors and signal lines connecting the sensors to a driving circuit for sensing a touch. The signal lines may include reception signal lines and transmission signal lines. A resistance value of the reception signal line connected to the sensor relatively far from the driving circuit is smaller than a resistance value of the reception signal line connected to the sensor relatively close to the driving circuit.

  • Patent number: 10627952
    Abstract: Some embodiments of the present invention provide a touch detection method and system. The touch detection method comprises: performing a spread spectrum process on a driving signal to generate a spectrum-spread signal; outputting the spectrum-spread signal to a driving terminal of a touch screen; receiving, from a response terminal of the touch screen, a coupled signal formed by coupling the spectrum-spread signal received by the driving terminal to the response terminal; and performing a de-spread spectrum process on the coupled signal to obtain a touch detection signal. Employing the embodiments of the present invention, an accuracy of a detection of a location on the touch screen can be improved by a spread spectrum technology, so as to enhance an anti-interference ability of a touch-controlled device.
