  • Patent number: 10120460
    Abstract: An optical computer mouse senses movement by detecting the variations in intensity of reflected primary colors from a surface over which the mouse is moved. The surface is illuminated by a plurality of colors of light. An image sensor is formed from an array of photodiodes covered with a color filter array that matches the primary colors of the lights and is used to detect intensity of reflected light of the primary colors from the surface on which the optical computer mouse rests. Variations in the intensity of at least one of the primary colors of reflected light are used to determine movement by the computer mouse. Both the intensity of the individual lights and sensitivity of the array of photo diodes are controlled by a controller.

  • Patent number: 10067575
    Abstract: A touch sensitive device can be capable of detecting signals generated by a stylus and correcting the detected stylus signals for effects due to noise present on the device. In one example, signals are taken from one or more electrodes that are a pre-determined distance away from an electrode in which a stylus signal is detected. The pre-determined distance can be empirically determined such that a noise estimate can be generated such that the electrodes have a higher probability of containing only noise that is highly correlated to the noise present on a detected stylus signal. The generated noise estimate is then subtracted from a detected stylus signal to reduce the effect of noise on the stylus signal.

  • Patent number: 9996196
    Abstract: A touch-sensitive apparatus comprises a panel configured to conduct signals from a plurality of peripheral incoupling points to a plurality of peripheral outcoupling points. Actual detection lines are defined between pairs of incoupling and outcoupling points to extend across a surface portion of the panel. The signals may be in the form of light, and objects touching the surface portion may affect the light via frustrated total internal reflection (FTIR). A signal generator is coupled to the incoupling points to generate the signals, and a signal detector is coupled to the outcoupling points to generate an output signal. A data processor operates on the output signal to enable identification of touching objects. The output signal is processed (40) to generate a set of data samples, which are indicative of detected energy for at least a subset of the actual detection lines.
