  • Patent number: 11137841
    Abstract: Devices and methods are disclosed for determining relative motion. In one implementation, an interferometer is provided. The interferometer may include a body, a light source configured to project a coherent light to an opposing surface, a plurality of pairs of light detectors configured to convert reflections of the coherent light into photocurrents, and a processor. The processor may be configured to detect changes in the photocurrents, wherein a first change in the photocurrents, which occurs in response to a relative motion between the body and the opposing surface, represents a motion signal, and a second change in the photocurrents represents a noise signal. The processor may also determine the relative motion between the body and the opposing surface based on the first change in the photocurrents when a ratio between a power of the motion signal and a power of the noise signal is below about 10.

  • Patent number: 9916041
    Abstract: An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. Touch events disturb the optical beams. Detection schemes define the operation of the touch capability. Different detection schemes consume different amounts of power and may be used in combination to reduce overall power consumption.

  • Patent number: 9778762
    Abstract: The information processor includes an input unit having an illuminating part and an image pickup part, and an input medium having an input surface on which inputting of information is carried out by the input unit which has position coordinates on the input surface coded by a dot pattern. The input unit irradiates light from the illuminating part onto input surface of the input medium. The irradiated light reflects off the dot contained in the dot pattern which is picked up by the image pickup part, and position information of the dot pattern is obtained. The input unit further has an input unit angular position measuring part that measures an angular position of the input unit when the light is irradiated. Based on corrected position information obtained by correction processing based on the angular position, input information, that is specified by the position coordinates is obtained.
