Publication number: 20210364992Abstract: A protective case for smart watch may include a main body disposed around a smart watch to provide the elastic protection effect. The main body formed in a frame shape has two connecting edges, a controlling edge, and an audio edge, which are formed with the same thickness. The two connecting edges are formed in parallel, and each of the connecting edges has an engaging slot to couple with the watch strap of the smart watch. An audio recess concavely formed on an inner surface of the audio edge is configured to couple with a lateral side of the smart watch. The audio recess has a bottom portion communicated with the location of the speaker of the smart watch, and the audio recess is extended to the display of the smart watch to form a top opening.Type: ApplicationFiled: May 20, 2021Publication date: November 25, 2021Applicant: 3DWIND TECHNOLOGY CO., LTD.Inventors: Shih-Cheng Yang, Tsuo-Fei Mao

Publication number: 20190213641Abstract: The present invention discloses a message transmission method. A first portable device transmits an identity information of a first wireless signal transmitter and a message content to a cloud server. The cloud server analyzes the message content to obtain a message tag of the message content, and obtain a wireless signal transmitter tag of the first wireless signal transmitter according to the identity information. The cloud server then obtains at least one target identity information representing at least one target wireless signal transmitter by using the message tag and the wireless signal transmitter tag, to obtain an association between the message content and the at least one target identity information. When receiving a second identity information, a second portable device compares the second identity information with the at least one target identity information and receives the message content from the cloud server.Type: ApplicationFiled: March 6, 2018Publication date: July 11, 2019Inventors: Jia-Ming You, Shih-Cheng Yang, Cheng-Yang Chen

Patent number: 9577947Abstract: Techniques are provided for managing network traffic and alleviating network congestion issues in video conference environments. At a video conference bridge device configured to send and receive communications to an endpoint device in a network, one or more video streams are received from the endpoint participating in a video conference. Each of the video streams is classified as a rate adaptive stream or as a non-rate adaptive stream. For video streams classified as rate adaptive streams, the video streams are assigned to a buffer queue for rate adaptive streams. For video streams classified as non-rate adaptive streams, the video streams are assigned to a buffer queue for non-rate adaptive streams.Type: GrantFiled: July 19, 2013Date of Patent: February 21, 2017Assignee: Cisco Technology, Inc.Inventors: Duanpei Wu, Shih-Cheng Yang, Wenyi Wang, Anand Oswal

Patent number: 9378314Abstract: A system and method for designing integrated circuits and predicting current mismatch in a metal oxide semiconductor (MOS) array. A first subset of cells in the MOS array is selected and current measured for each of these cells. Standard deviation of current for each cell in the first subset of cells is determined with respect to current of a reference cell. Standard deviation of local variation can be determined using the determined standard deviation of current for one or more cells in the first subset. Standard deviations of variation induced by, for example, poly density gradient effects, in the x and/or y direction of the array can then be determined and current mismatch for any cell in the array determined therefrom.Type: GrantFiled: August 25, 2014Date of Patent: June 28, 2016Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Amit Kundu, Jaw-Juinn Horng, Yung-Chow Peng, Shih-Cheng Yang, Chung-Kai Lin

Patent number: 8982702Abstract: An apparatus may receive a plurality of data streams for transmission over a network. The apparatus may adjust packet drop rates in proportion to differences between actual bit rates and target bit rates of the data streams. Information about the adjusted packet drop rates may be provided to rate adaptive endpoints that are generating the data streams. The rate adaptive endpoints may respond to the information by adjusting the bit rates at which the data streams are encoded. Over one or more time intervals, the bit rates are adjusted to levels that yield a transmission of the data streams that is both balanced and unbiased.Type: GrantFiled: October 30, 2012Date of Patent: March 17, 2015Assignee: Cisco Technology, Inc.Inventors: Duanpei Wu, Shih-Cheng Yang, Anand Oswal, Wenyi Wang
