Publication number: 20220408365Abstract: A power optimization method for uplink data transmission is provided. The power optimization method is applied to user equipment (UE). The power optimization method includes the following steps. The UE determines the current application scenario of the UE. The UE determines the data transmission window corresponding to the current application scenario. Data transmission windows corresponding to different application scenarios of the UE have at least one of different period to transmit data and different period to enter suspension. The UE may transmit data based on the determined data transmission window.Type: ApplicationFiled: June 9, 2022Publication date: December 22, 2022Inventors: Chiao-Chih CHANG, I-Wei TSAI, Jun-Jie SU, Ho-Wen PU, En-Jung FARN

Patent number: 9311652Abstract: A method, an apparatus, and a system for generating and verifying a color barcode are provided. The method for verifying the color barcode is adapted to an electronic apparatus to execute verification with use of a color barcode certificate. In the method, direction information of a plurality of boundaries among a plurality of serially connected symbolic elements in the color barcode certificate is read to retrieve first authentication information of a first party. Each of the symbolic elements is one of at least two polygons, and colors of adjacent symbolic elements are different. Color information of the symbolic elements is then read to retrieve second authentication information of a second party. An identity of a holder of the color barcode certificate is verified according to the first authentication information and the second authentication information.Type: GrantFiled: May 19, 2014Date of Patent: April 12, 2016Assignee: Industrial Technology Research InstituteInventors: En-Jung Farn, You-Lin Chen, Chih-Wei Chen, Nien-Chu Wu

Publication number: 20150186429Abstract: A system and a method for data dispatch processing in a big data system are provided. The system includes a plurality of computing machines and a database cluster. The method includes disassembling a computing procedure into a plurality of processing elements. The method also includes identifying a database accessing point for accessing a target data node from one of the data nodes in the computing procedure. The method further includes configuring the processing elements to the computing machines according to the database accessing point, and transmitting a data tuple corresponding to the computing procedure according to the processing elements configured to the computing machines and a data transmitting cost between the computing machines. Accordingly, the method effectively improves system performance for transmitting the big data.Type: ApplicationFiled: September 19, 2014Publication date: July 2, 2015Inventors: You-Lin Chen, Leii H. Chang, En-Jung Farn, Nien-Chu Wu

Patent number: 9001206Abstract: A cascadable camera tampering detection transceiver module has a processing unit and a storing unit, an information controlling module and an analyzing module. The storing unit stores a transceiving module. The detection module analyzes input video, detects camera tampering events, synthesizes the input video with the image of camera tampering result, and outputs the synthesized video. When the input video is an output from the detection module, the detection module separates the camera tampering result from the input video, and the result can be used to simplify or enhance the subsequent video analysis. Performing the existing analysis repeatedly may be avoided, and the user may re-define the detection conditions in this manner. When the camera tampering result is transmitted in the video channel, the detection module transmits the camera tampering result, and hence the detection module may be used in combination with surveillance devices having image output or input interfaces.Type: GrantFiled: August 22, 2011Date of Patent: April 7, 2015Assignee: Industrial Technology Research InstituteInventors: Shen-Zheng Wang, San-Lung Zhao, Hung-I Pai, Kung-Ming Lan, En-Jung Farn

Patent number: 8702011Abstract: A barcode structure includes at least one symbolic element row and a frame arranged at a periphery of the at least one symbolic element row. Each symbolic element row has multiple symbolic elements. Each symbolic element has different color from its adjacent symbolic elements, and the color of the frame is different from that of any symbolic element. A barcode encoding method includes: establishing multiple color combinations where a color of a frame is excluded, and each color combination comprising a main color and a sub color; performing a symbolic element row establishment procedure, which includes using a reference color as a color of a first symbolic element of a symbolic element row; deleting color combinations where the reference color is used as a main color; and selecting a color combination from remaining color combinations for coloring two symbolic elements that are sequentially connected with the first symbolic element.Type: GrantFiled: January 16, 2013Date of Patent: April 22, 2014Assignee: Industrial Technology Research InstituteInventors: En-Jung Farn, Chih-Wei Chen, Chung-Chia Kang, Nien-Chu Wu
