Patent number: 10712881Abstract: Provided is an input device including a sensor part to detect approaching states of objects at detection positions and an adjacent region specification part to specify adjacent regions of the objects based on detection data from the sensor part. The adjacent region specification part specifies a peak detection position, of which a value of the detection data satisfies a certain peak condition among the detection positions, and conducts a label assigning process that assigns a label applied at the peak detection position to one or more detection positions among surrounding detection positions of the peak detection position. The label is not assigned to the one or more detection positions, and the detection data of the one or more detection positions indicate greater than or equal to a first threshold defined based on the detection data of the peak detection position being specified.Type: GrantFiled: December 13, 2017Date of Patent: July 14, 2020Assignee: ALPS ALPINE CO., LTD.Inventor: Tomoki Yamada

Patent number: 10712883Abstract: Disclosed herein is a touch screen controller operable with a touch screen. The touch screen controller includes input circuitry to receive touch data from the touch screen, and processing circuitry. The processing circuitry acquires mutual capacitance touch strength values from the touch screen, determines when the mutual capacitance touch strength values define a pre-validated donut touch pattern, and reads self capacitance touch strength values for lines that are contained within bounds of the pre-validated donut touch pattern. If the self capacitance touch strength values for lines contained within bounds of the pre-validate donut touch pattern contain a singular peak value, the processing circuitry validates the pre-validated donut touch pattern as representing a single touch.Type: GrantFiled: February 9, 2018Date of Patent: July 14, 2020Assignee: STMicroelectronics Asia Pacific Pte LtdInventor: Manivannan Ponnarasu

Patent number: 10712884Abstract: Examples are disclosed herein that relate to various operational modes of a capacitive touch sensor. One example provides a touch-sensitive input device comprising receive circuitry, a capacitive touch sensor having a plurality of portions, and a controller. The controller is configured to, responsive to not detecting a finger or a pen, operate the touch sensor in a locating mode by successively driving each portion with a fixed DC voltage and multiplexing the portion to the receive circuitry in a predefined sequence, and responsive to detecting the pen, operate the touch sensor in a tracking mode by driving a selected portion with the fixed DC voltage and multiplexing the selected portion to the receive circuitry to track the pen, the selected portion selected based on a detected location of the pen relative to the touch sensor and being varied as the detected location changes.Type: GrantFiled: April 23, 2018Date of Patent: July 14, 2020Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Arie Yehuda Gur, Zohar Nagola, Jonathan Westhues

Patent number: 10712885Abstract: A touch screen device incorporating a display and a capacitive touch sensor. The device has a mode of operation in which a single touch sensor measurement is made up of multiple charge accumulations, which take place in different display cycles, ‘H-sync’, and whose time windows, defined by switch ‘S1’, commence with different time delays, 0, ?t1 and (?t1+?t2) from the drive pulse edge, ‘drive’, whose induced charge transfer they are accumulating. By subdividing the measurement into multiple charge accumulations, the amount of time needed in each display cycle for performing the touch sensor measurement can be reduced to avoid coinciding with periods of high display-induced noise.Type: GrantFiled: August 21, 2018Date of Patent: July 14, 2020Assignee: Solomon Systech (Shenzhen) LimitedInventor: David Keith Bye
