Patent number: 11061793Abstract: Circuits, methods, and apparatus that may estimate the power being consumed by an OLED display screen of an electronic device, may provide further information about that power usage, may modify or change functions performed by the electronic device based on that power usage, and may inform an application's developer about the amount of power being used by the electronic device while the electronic device is running the application. One example may estimate the power being used by an OLED display screen of an electronic device by determining the content of images being displayed during a duration. The estimated power may then be presented to a user. The estimated power may be used in decisions to modify or change parameters of the screen or other device components.Type: GrantFiled: February 20, 2018Date of Patent: July 13, 2021Assignee: Apple Inc.Inventors: Abhinav Pathak, Conor J.

Patent number: 9025676Abstract: A method, system and device are provided for pre-filtering device for filtering a video signal prior to digitally encoding. The method includes receiving at least one input picture and at least one reconstructed picture from an encoding process and performing an in-loop temporal filtering process using at least one input picture and at least one reconstructed picture from an encoding process to output a pre-filtered video signal for use in an encoding process. The result is enabling an encoding process to produce an output with increased temporal correlation between adjacent pictures regardless of the coding type, since the artifacts introduced by the encoding process are also considered by the process.Type: GrantFiled: July 10, 2012Date of Patent: May 5, 2015Assignee: GEO Semiconductor Inc.Inventors: José Roberto Alvarez, Lulin Chen, Alexandros Michael Tourapis

Patent number: 8355536Abstract: A passive electro-optical tracker uses a two-band IR intensity ratio to discriminate high-speed projectiles and obtain a speed estimate from their temperature, as well as determining the trajectory back to the source of fire. In an omnidirectional system a hemispheric imager with an MWIR spectrum splitter forms two CCD images of the environment. Three methods are given to determine the azimuth and range of a projectile, one for clear atmospheric conditions and two for nonhomogeneous atmospheric conditions. The first approach uses the relative intensity of the image of the projectile on the pixels of a CCD camera to determine the azimuthal angle of trajectory with respect to the ground, and its range. The second calculates this angle using a different algorithm. The third uses a least squares optimization over multiple frames based on a triangle representation of the smeared image to yield a real-time trajectory estimate.Type: GrantFiled: February 22, 2010Date of Patent: January 15, 2013Assignee: Light Prescriptions Innovators LLCInventors: Ilya Agurok, Waqidi Falicoff, Roberto Alvarez

Patent number: 8311094Abstract: A video stream is digitally encoded such that the rate at which individual segments of data are encoded varies according to the amount of data required to generate each segment. Frames are selectively omitted from transmission (32) such that the cumulative frame rate does not fall below a predetermined value. This process can be used to ensure that the next frame to be displayed is always available in the buffer store 6 associated with the decoder (2). The decoder (2) is arranged to identify where frames have been omitted from the decoded transmission, and to perform a resynchronisation (7) on the decoded stream by comparison between time stamps in the video stream and a corresponding audio stream. Resynchronisation may be performed by extending the durations of individual frames, or by repeating frames.Type: GrantFiled: December 8, 2005Date of Patent: November 13, 2012Assignee: British Telecommunications PLCInventors: Othon Kamariotis, Rory Stewart Turnbull, Roberto Alvarez Arevalo
