Publication number: 20240045518Abstract: Disclosed herein is a method executed by a device that is configured to be able to detect a pointed position of a stylus on an operation plane being superimposed on a displaying part. The method includes receiving feedback information relating to a display position of a predetermined pattern on the displaying part from a host processor, updating at least some of plural position calibration values stored in a correction table that stores therein the position calibration value for each of plural positions arranged on the operation plane, on a basis of the received feedback information, detecting a tentative pointed position of the stylus, reading the position calibration value that corresponds to the tentative pointed position from the correction table and deriving an output position by correcting the tentative pointed position on a basis of the position calibration value, and reporting the output position to the host processor.Type: ApplicationFiled: October 20, 2023Publication date: February 8, 2024Applicant: Wacom Co., Ltd.Inventors: Shunya Saito, Shigeyuki Sano, Igor Karsuntsev, JuiMin Liu, Jun Kadowaki

Patent number: 11842000Abstract: A sensor system, which detects a stylus and is provided in an electronic apparatus, includes a first integrated circuit, a second integrated circuit, and an integrated circuit connection line that couples the first integrated circuit and the second integrated circuit to each other. The first integrated circuit is connected to a first sensor electrode group, and detects a position of the stylus on a panel face of a first housing. The second integrated circuit is connected to a second sensor electrode group, and detects a position of the stylus on a panel face of a second housing. When the first integrated circuit detects a presence of the stylus, a notification indicative of the detection is issued to the second integrated circuit through the integrated circuit connection line such that transmission of an uplink signal through the second sensor electrode group by the second integrated circuit is stopped.Type: GrantFiled: October 5, 2020Date of Patent: December 12, 2023Assignee: Wacom Co., Ltd.Inventors: Igor Karsuntsev, Shigeyuki Sano, Kenichi Ono

Patent number: 10795468Abstract: A sensor system that detects a stylus is provided in an electronic apparatus, which includes a first housing, a second housing, a connector that connects the first housing and the second housing to each other, and a host processor. The sensor system includes a first sensor electrode group fixed to the first housing, and a second sensor electrode group fixed to the second housing. When the stylus is not detected, an uplink signal is transmitted through each of the first and second sensor electrode groups. When a downlink signal by which the stylus is detected that is transmitted from the stylus is detected by the first sensor electrode groups, the transmission of the uplink signal through the first sensor electrode group is continued while transmission of the uplink signal through the second sensor electrode groups is stopped.Type: GrantFiled: January 18, 2019Date of Patent: October 6, 2020Assignee: Wacom Co., Ltd.Inventors: Igor Karsuntsev, Shigeyuki Sano, Kenichi Ono

Patent number: 10678392Abstract: A push determination determines whether an indicator has pushed or touched a local region of an interface in a touch sensor used with a display panel that displays a graphical user interface. A method according to the present disclosure includes: outputting area data corresponding to a size of a tracking region and sum total data corresponding to a sum total value of level values at positions included in the tracking region; and, in a case where the sum total data indicates the sum total value is greater than a predetermined sum total value, determining an event corresponding to a push operation is to be output when the area data indicates a second area value smaller than a first area value and determining an event corresponding to a touch operation is to be output when the area data indicates the first area value.Type: GrantFiled: March 4, 2019Date of Patent: June 9, 2020Assignee: Wacom Co., Ltd.Inventors: Shigeyuki Sano, Igor Karsuntsev
