摘要： A gesture sensing device includes a single light source and a multiple segmented single photo sensor, or an array of photo sensors, collectively referred to herein as segmented photo sensors. A light modifying structure relays reflected light from the light source onto different segments of the segmented photo sensors. The light modifying structure can be an optical lens structure or a mechanical structure. The different segments of the photo sensor sense reflected light and output corresponding sensed voltage signals. A control circuit receives and processes the sensed voltage signals to determine target motion relative to the segmented photo sensor.

摘要： Embodiments of the present invention provide systems, devices and methods for detecting both ambient light and proximity to an object. This detection is performed by a double-layered photodiode array and corresponding circuitry such that ambient light and proximity detection are enabled by a plurality of integrated photodiodes. In various embodiments of the invention, ambient light is sensed using a first set of photodiodes and a second set of photodiodes such that a spectral response is created that is approximately equal to the visible light spectrum. Proximity detection is realized using an integrated photodiode, positioned below the first and second sets of photodiodes, that detects infrared light and generates a response thereto.

摘要： A system and method for generating an approximated position signal that is updated and output at a rate higher than a base rate of actual position signals measured using a position transducer. The actual position signals are determined and/or stored by a transducer signal processing circuit at discrete time intervals. The approximated position signals are generated by a high frequency estimated position generating circuit. A rate of incrementing the approximated position signals is adjusted for use during the next discrete time interval by an error correction feedback loop, based on a difference between certain approximated and actual position values. The accuracy of the system may be further improved by utilizing a latch signal to ensure that the approximated and actual position values that are compared by the error feedback loop correspond to the same time.

摘要： A circuit for detecting a phase error between a clock signal and a beam position includes a beam generator, a sensor, and a phase detector. The beam generator directs a beam toward a beam sweeper in response to the clock signal, and the sensor detects the beam as directed from the beam sweeper. The phase detector determines from the detected beam the error in the clock phase relative to the beam position. Such a circuit can automatically detect the phase error in the pixel clock and correct this error, thus eliminating the need for a manual phase-error corrector. The circuit may also be able to adjust the width and/or the height of a scan region, and thus may also be able to adjust the width and/or height of an image frame within the scan region.

摘要： An apparatus for detecting a centroid of a spot produced by electromagnetic radiation, e.g., optic radiation, using an array of PIN photodiodes serving as photodetectors and being organized in columns and in rows. Vertical connections are used to interconnect the PIN photodiodes in the columns in accordance with a first pattern that interconnects two or more adjacent columns. Horizontal connections are used to interconnect PIN photodiodes in the rows in accordance with a second pattern that interconnects two or more adjacent rows. The first and second patterns of interconnections can include just two adjacent columns and two adjacent rows, respectively and form a checkerboard interconnect pattern. The interconnections are made such that there are no anode connections between the PIN photodiodes in the rows and columns. The apparatus has a processing circuitry for rapidly deriving an X-extent of the centroid from current signals obtained from the columns and a Y-extent of the centroid from current signals obtained from the rows.
