  • Patent number: 10151805
    Abstract: A method includes acquiring magnetic data from a magnetometer, processing the magnetic data to perform robust calibration, and generating optimum calibration parameters using a calibration status indicator. To that end, the method includes generating a calibration status indicator as a function of time elapsed since a last calibration and variation in total magnetic field in previously stored magnetic data, detecting anomalies, and extracting a sparse magnetic data set using comparison between the previously stored magnetic data and the magnetic data. Calibration parameters are generated for the magnetometer using a calibration method as a function of the magnetic data set. The calibration parameters are stored based on performing a validation and stability check on the calibration parameters, and weighted with the previously stored calibration parameters to produce weighted calibration parameters.

  • Patent number: 10152161
    Abstract: A touch screen controller is for a drive line emitting a periodic signal and capacitively intersecting sense lines. A selection circuit, for each of a number of portions of the periodic signal equal to a number of the sense lines, couples a first subset of the sense lines to a first output path, and couples a second subset of the sense lines to a second output path, the second subset being sense lines not included in the first subset. Processing circuitry, for each portion of the periodic signal, measures a capacitance of the first output path, measures a capacitance of the second output path, and sums the capacitance of the first output path and the capacitance of the second output path. The processing circuitry determines a capacitance between each sense line of the first and second subsets and the drive line as a function of the sums.

  • Publication number: 20180348506
    Abstract: Disclosed herein is a mirror controller for an oscillating mirror. The mirror controller includes a processor configured to receive a mirror sense signal from the oscillating mirror and to determine a phase error between the mirror sense signal and a mirror drive signal. The processor determines the phase error by sampling the mirror sense signal at a first time, sampling the mirror sense signal at a second time at which the mirror sense signal is expected to be equal to the mirror sense signal as sampled at the first time, and generating the phase error as a function of a difference between the sample of the mirror sense signal at the second time and the sample of the mirror sense signal at the first time.

  • Publication number: 20180350839
    Abstract: A transistor is fabricated by growing an epitaxial layer of semiconductor material on a semiconductor layer and forming an opening extending through the epitaxial layer at the gate location. This opening provides, from the epitaxial layer, a source epitaxial region on one side of the opening and a drain epitaxial region on an opposite side of the opening. The source epitaxial region and a first portion of the semiconductor layer underlying the source epitaxial region are annealed into a single crystal transistor source region. Additionally, the drain epitaxial region and a second portion of the semiconductor layer underlying the drain epitaxial region are annealed into a single crystal transistor drain region. A third portion of the semiconductor layer between the transistor source and drain regions forms a transistor channel region. A transistor gate electrode is then formed in the opening above the transistor channel region.
