Patent number: 9645887Abstract: A system and method for firmware upgrade in an AMI are provided. A remote server provides a firmware image file. After receiving the firmware image file and verifying the remote server, a data concentrator transmits at least one encoding symbol generated from the firmware image file to at least one meter through broadcasting and a retransmission mechanism of minimum retransmission contents. Upon receiving a predetermined number of encoding symbols, each meter recovers the original firmware image file from the received encoding symbols. Then, each meter receives and verifies an activation code generated by the remote server before carrying out the firmware upgrade.Type: GrantFiled: September 16, 2014Date of Patent: May 9, 2017Assignee: Industrial Technology Research InstituteInventors: Yao-Hsin Chen, Ping-Hai Hsu

Patent number: 9449352Abstract: An exemplary embodiment provides a load management system, including a detecting module and a determining module. The detecting module creates at least one activated one of a plurality of loads located in a predetermined space as an activation set, and creates a group set including a plurality of sub-groups according to locations and activation times of the activated ones of the plurality of loads. The detecting module creates the activated ones of the plurality of loads which have been activated within a predetermined time period as one of the sub-groups. The determining module determines whether each of the activated ones of the plurality of loads is an essential load or a non-essential load according to the group set and the activation set to produce a determining result.Type: GrantFiled: July 30, 2012Date of Patent: September 20, 2016Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Wen-Shiang Tang, Ping-Hai Hsu

Patent number: 8417665Abstract: An information extraction method for extracting dynamic information is provided. The method includes using a plurality of information extractors extracting reference values corresponding to the dynamic information from a plurality of information sources, and determining a most reliable value corresponding to the dynamic information based on the reference values. The method further includes determining whether each of the information extractors is abnormal according to the most reliable value and removing the information extractors determined as abnormal. The method further includes rebuilding new information extractors for replacing the removed information extractors. In such a way, reliable dynamic information can be extracted and the information extractors can be maintained for normal operation.Type: GrantFiled: December 17, 2009Date of Patent: April 9, 2013Assignee: Industrial Technology Research InstituteInventors: Yen-Yu Chen, Ping-Hai Hsu

Publication number: 20080153317Abstract: Disclosed is a fabric interfacing architecture for a node blade. The fabric interfacing architecture comprises a fabric interface unit and a control unit. The fabric interface unit includes a switch and an E-keying element. The control unit receives control signals from an external web server to control the fabric interface unit. The control unit respectively controls the switch and the E-keying element through different control signals. The fabric interfacing architecture is utilized together with a back plane of a shelf and one or more physical layers of the node blade. This allows flexible PHY-to-Channel/Port routings, thereby achieving the support for multiple topology modes. The invention may on-line adjust the assignments of communication channels and ports according to the needs for physically applied bandwidths, which optimizes the bandwidth utilization.Type: ApplicationFiled: May 21, 2007Publication date: June 26, 2008Inventors: Ping-Hai Hsu, Yen-Liang Liu, Kuo-Pao Fan
