Publication number: 20240147596Abstract: A two-way load control system comprises a power device, such as a load control device for controlling an electrical load receiving power from an AC power source, and a controller adapted to be coupled in series between the source and the power device. The load control system may be installed without requiring any additional wires to be run, and is easily configured without the need for a computer or an advanced commissioning procedure. The power device receives both power and communication over two wires. The controller generates a phase-control voltage and transmits a forward digital message to the power device by encoding digital information in timing edges of the phase-control voltage. The power device transmits a reverse digital message to the controller via the power wiring.Type: ApplicationFiled: January 12, 2024Publication date: May 2, 2024Applicant: Lutron Technology Company LLCInventors: Mark S. Taipale, Timothy P. Gredler, Akshay Bhat

Patent number: 11145249Abstract: A display may include pixels (such as light-emitting diode pixels) that are susceptible aging effects (burn-in). To help avoid visible artifacts caused by burn-in during operation of the display, compensation circuitry may be used to compensate image data for the display. An optical sensor may be included behind the pixels to directly measure pixel brightness levels. The optical sensor may provide optical sensor data from testing operations to the compensation circuitry. The optical sensor may gather data during burn-in testing operations. During the burn-in testing operations, pixel groups including both high-usage pixels and low-usage pixels may sequentially emit light while the optical sensor gathers data. Brightness differences between the high-usage pixels and low-usage pixels may be used to characterize pixel aging in the display and compensate image data to mitigate visible artifacts caused by burn-in. The optical sensor may also gather data during global brightness testing operations.Type: GrantFiled: July 15, 2020Date of Patent: October 12, 2021Inventors: Wanglei Han, Akshay Bhat, Michael H. Lim, Kyung Hoae Koo, Jiayi Jin, David A. Doyle, Tae-Wook Koh, Jared S. Price, Yifan Zhang, Mahdi Nezamabadi

Patent number: 10720126Abstract: A color ambient light sensor may gather ambient light measurements during operation of an electronic device. The color ambient light sensor may have a color ambient light detector and an adjustable neutral density filter. The electronic device may have components such as a camera and display that are adjusted using ambient light information from the color ambient light sensor. The display may have a display cover layer. Pixels in an active area of the display may display images through the display cover layer. An inactive area of the display may have an opaque masking layer on an interior surface of the display cover layer. An opening in the opaque masking layer may form an ambient light sensor window for the color ambient light sensor. The adjustable neutral density filter may be interposed between the color ambient light detector and the ambient light sensor window.Type: GrantFiled: August 31, 2018Date of Patent: July 21, 2020Assignee: Apple Inc.Inventors: Akshay Bhat, Rui L.
