Patent number: 11474641Abstract: In certain embodiments, a method includes performing a first positive integration by sensing a first rising edge of a charging signal of a touch sensor during a first synchronization period and performing a first negative integration by sensing a first falling edge of the charging signal during a second synchronization period. The method also includes toggling the charging signal, resulting in a second rising edge of the charging signal during the second synchronization period. The method further includes performing a second negative integration by sensing a second falling edge of the charging signal during a third synchronization period and performing a second positive integration by sensing a third rising edge of the charging signal during a fourth synchronization period. The first integrations are associated with a first sample measurement and the second integrations are associated with a second sample measurement.Type: GrantFiled: October 20, 2020Date of Patent: October 18, 2022Assignee: Atmel CorporationInventors: Grahame Reynolds, Hammad Syed

Patent number: 10162464Abstract: In certain embodiments, a touch sensor controller estimates an area of a display screen that a display controller will update at a first time and estimates an area of a touch sensor that the touch sensor controller is expected to scan at the first time. The touch sensor controller further identifies an expected interference based on a comparison between the update of the estimated area of the display screen by the display controller at the first time and the scan of the estimated area of the touch sensor by the touch sensor controller at the first time. Based on the expected interference, the touch sensor controller suspends, for a first time period, the scan of the estimated area of the touch sensor for touch events based on the expected interference. The touch sensor controller resumes the scan after the first time period.Type: GrantFiled: February 5, 2018Date of Patent: December 25, 2018Assignee: Atmel CorporationInventors: Samuel Brunet, Grahame Reynolds, Hammad Syed

Patent number: 9727168Abstract: In one embodiment, a method includes receiving a request to refresh a display for a refresh period, wherein the display is coupled to a touch sensor operable to detect touch input at the display. During a first phase of the refresh period, a first portion of the display is refreshed while the touch sensor a second portion and a third portion of the display is activated. The second portion and the third portion are a half screen distance apart. During a second phase of the refresh period, the second portion of the display is refreshed while the touch sensor at a fourth portion and a fifth portion of the display is activated. The fourth portion and the fifth portion are a half screen distance apart.Type: GrantFiled: July 29, 2016Date of Patent: August 8, 2017Assignee: Atmel CorporationInventors: Andrew Fuller, Samuel Brunet, Christopher Hill, Vivek Pant, Grahame Reynolds
