Patent number: 11403993Abstract: A light-emitting diode display device and a light-emission control method thereof are provided. The light-emitting diode display device includes a timing controller, multiple display pixels, and a scanning circuit. The display pixels form multiple display rows. The scanning circuit generates multiple scan signals and multiple light-emission signals that respectively drive the display rows. During a first data-writing time period of a first frame period, the timing controller provides multiple writing data to be respectively written into the display rows. During a light-emitting time period, the scanning circuit drives each of the light-emission signals to generate multiple pulses periodically according to a set period to drive the corresponding display rows. The light-emitting time period is after the first data-writing time period and before a second data-writing time period of a second frame period ends.Type: GrantFiled: March 3, 2021Date of Patent: August 2, 2022Assignee: Au Optronics CorporationInventors: Yu-Chieh Kuo, Yu-Hsun Chiu, Kai-Hsiang Liu, Che-Chia Chang, Shang-Jie Wu, Mei-Yi Li, Peng-Bo Xi, Chin I Chiang, Yan-Ru Chen, Ting-Wei Guo, Chia-Ting Hsieh

Patent number: 10895625Abstract: A computer-implemented method and a server for device positioning. The computer-implemented method includes receiving a control message from a positioning server. The control message indicates a set of channels associated with an area and time periods for monitoring the set of channels. At least one measurement of a signal from at least one of a reference device for the area and a target device is obtained, according to the control message, with the reference device being located at a predefined position with respect to the area. The at least one measurement is reported to the positioning server for determining a position of the target device with respect to the area.Type: GrantFiled: December 3, 2018Date of Patent: January 19, 2021Assignee: International Business Machines CorporationInventors: Yu Bo Li, Yong Hua Lin, Qing Wang, Chao Xue

Publication number: 20190178977Abstract: A computer-implemented method and a server for device positioning. The computer-implemented method includes sending a control message to a detector. The control message indicates a set of channels associated with an area and time periods for monitoring the set of channels. A measurement of a signal from a device for the area and a target device is received from the detector. Position of the target device with respect to the area is determined based on a measurement and a radio map. The radio map indicates signal strength corresponding to positions in the area.Type: ApplicationFiled: December 3, 2018Publication date: June 13, 2019Inventors: Yu Bo Li, Yong Hua Lin, Qing Wang, Chao Xue

Patent number: 9826339Abstract: In one embodiment, a system includes a first tracked device and a second tracked device. The first tracked device includes first known device data, describing one or more previous connections known to the first tracked device. The second tracked device includes second known device data, describing one or more previous connections known to the second tracked device. The first tracked device is configured to connect to the second tracked device, transfer to the second tracked device at least a portion of the first known device data, and receive from the second tracked device at least a portion of the second known device data. The first tracked device is further configured to modify the first known device data to incorporate the second known device data. The second known device data includes data related to a previous connection involving a third tracked device outside a signal range of the first tracked device.Type: GrantFiled: June 22, 2015Date of Patent: November 21, 2017Assignee: International Business Machines CorporationInventors: Yu Bo Li, Tian Cheng Liu, Ke Wei Sun, Chao Xue, Boa Hua Yang
