Publication number: 20240077929Abstract: The present disclosure describes systems and methods associated with selective powering of an electronic display in response to sensed data indicating that the electronic display is not visible. By selectively enabling the electronic display between power states based on whether the electronic display is visible, a perceivably always-on electronic display may be provided without the electronic display being always-on, thereby balancing consumer interests with technical requirements of a relatively long battery life and correspondingly low power consumption.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Inventors: Joseph F. Alverson, Brad W. Simeral, Daniel J. Drusch, Daniel P. Kumar, Derek J. DiCarlo, Ricky Wai Kit Yuen, Roberto G. Yepez, Shashi K. Dua, Ardra Singh, Gabrielle Andrea Badie Belzberg, Kartik Venkatraman, Gierad Laput, Archana Venkatesh, Jingran Zhou

Publication number: 20240077930Abstract: The present disclosure describes systems and methods associated with selective powering of an electronic display in response to operating conditions, additional data, and/or predicting that the electronic display is not going to be viewed or visible. By selectively enabling the electronic display between power states based on a prediction of when a viewer is expected to view the electronic display, a perceivably always-on electronic display may be provided without the electronic display being always-on, thereby balancing consumer interests with technical requirements of a relatively long battery life and correspondingly low power consumption.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Inventors: Joseph F Alverson, Brad W. Simeral, Daniel J. Drusch, Daniel P. Kumar, Derek J. DiCarlo, Ricky Wai Kit Yuen, Roberto G. Yepez, Shashi K.

Publication number: 20240019522Abstract: Performing a combination localization technique includes determining a target localization parameter, selecting a combination localization technique in accordance with the target localization parameter, including a first localization technique associated with a first power error time profile, and a second localization technique associated with a second power error time profile. A device location is determined using the first localization technique for a first time period in accordance with the first power error time profile, and an updated device location is determined using the second localization technique in response to a triggering condition. A further updated device location is determined using the first localization technique following the first time period based on the updated device location. At least one of a combined energy value and a combined maximum error rate for the combination localization technique satisfies the target localization parameter.Type: ApplicationFiled: July 17, 2023Publication date: January 18, 2024Inventors: Siddharth S.

Patent number: 11614791Abstract: An electronic device may include a display panel. When content of an image frame is expected to consume relatively higher amounts of power, a controller of the electronic device may operate a switch to change a power supply of the display panel to be a power management integrated circuit of the electronic device. However, when content of an image frame is expected to consume relatively less amounts of power, the controller may operate the switch to change the power supply of the display panel to be a power supply of an electronic display, such as a power supply used to power driver circuitry of the electronic display.Type: GrantFiled: December 3, 2020Date of Patent: March 28, 2023Assignee: Apple Inc.Inventors: Ramana V.
