Patent number: 10726767Abstract: A display apparatus includes a display panel, a gate driver and a data driver. The display panel displays an image and includes first sub-pixels which display a first color, second sub-pixels which display a second color different from the first color, first gate lines to which only the first sub-pixels are connected, second gate lines to which only the second sub-pixels are connected, and data lines. The gate sequentially applies first gate signals only to the first gate lines during a first duration of a first frame, and sequentially applies second gate signals only to the second gate lines during a second duration of the first frame, where the second duration is subsequent to the first duration. The data driver outputs data voltages to the data lines based on input image data in synchronization with a driving sequence of the first and second gate lines.Type: GrantFiled: April 3, 2018Date of Patent: July 28, 2020Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Haengwon Park, Hyeonseok Bae, Myoung Jun Chai, Seunghoon Han, Dongwon Park

Patent number: 10263541Abstract: A single-phase DC/AC inverter has a single-phase inverter bridge with binary switches connected to an RLC low-pass filter. Digital control logic in a control circuit (or in a microcontroller) determines and controls a logic state q determining the position of the switches in the inverter bridge from sensed iL, vC values from the RLC filter. The control logic selects one of multiple possible logic states q based on whether the sensed iL, vC values belongs one of multiple boundary regions of a tracking band in an iL, vC state space.Type: GrantFiled: December 19, 2017Date of Patent: April 16, 2019Assignee: The Regents of the University of CaliforniaInventors: Ricardo G.

Patent number: 10047681Abstract: A method for detecting and controlling a load weight of a vehicle by means of a tire pressure of the vehicle and a device are provided. The method includes the steps of installation setting, detecting the load weight, and controlling an electric switch. The device includes tire pressure detectors installed on rear wheels of the vehicle and connected with a processor which is input with a preset tire pressure value and able to receive the tire pressure detected by the tire pressure detectors. The processor is connected with an electric switch of the vehicle. The processor compares the tire pressure detected by the tire pressure detectors with the preset tire pressure value, and controls the electric switch to turn on/off a power source of the vehicle. The device is capable of detecting and controlling the load weight of the vehicle by detecting a change of the tire pressure.Type: GrantFiled: December 20, 2016Date of Patent: August 14, 2018Inventor: Fang-Jun Chai
