Patent number: 11929018Abstract: A frame generation subsystem renders a sequence of frames and a display control subsystem provides a brightness control signal configured to control a brightness of frames displayed at a display panel via pulse width modulation (PWM) of the brightness control signal and determines a deviation in a duty cycle of a first PWM period of the brightness control signal from a default duty cycle resulting from a delayed rendering of a frame. The display control subsystem adjusts a duty cycle of at least a second PWM period to compensate for the deviation in the duty cycle of the first PWM period. The resulting average duty cycle of the brightness control signal over the two frame periods is approximately equal to a default duty cycle and thereby mitigates viewable flicker resulting from the duty cycle change caused by the delayed rendering.Type: GrantFiled: May 19, 2020Date of Patent: March 12, 2024Assignee: GOOGLE LLCInventors: Sang Young Youn, Sun-il Chang, Wonjae Choi, Hyunchul Kim

Patent number: RE39878Abstract: Disclosed is an apparatus for initiating an over the air parameter administration (OTAPA) of a mobile station without the need for interacting with a mobile station user. A unique service option number included with the initial page indicates to the mobile station that an update is being requested. The mobile station performs a network validation check (SPASM) before permitting the update to take place. Flags are used in the network to alert the system that an attempted update was not completed because a mobile station was not update accessible for any of several reasons. The flags cause the system to update when the mobile station next becomes update accessible. The questions raised in reexamination request No. 90/006,577, filed Mar. 25, 2003, have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e).Type: GrantFiled: February 21, 2003Date of Patent: October 9, 2007Assignee: Nortel Networks LimitedInventors: Athena (Yau-Fan) Leung, Robert E.
