Patent number: 9454415Abstract: In accordance with one aspect of the present description, an indication that a communication failure reported in a predetermined time interval is more likely the result of a software failure than a hardware failure may be made if the number of communication links reporting a communication failure in the predetermined time interval exceeds a communication link failure threshold, and the number of communication link devices such as nodes or communication paths which have been implicated as causing a communication failure, exceeds an implicated device threshold. Other features and aspects may be realized, depending upon the particular application.Type: GrantFiled: November 7, 2013Date of Patent: September 27, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Todd C. Sorenson, Liang Hua Wu

Patent number: 9262982Abstract: A timing controller for a liquid crystal panel and a timing control method thereof are provided. The timing controller includes a timing control unit for analyzing an input signal to generate a system state transition voltage (STV) signal and a base STV signal, and the timing control unit outputs a base trigger signal and a switch trigger signal having asynchronous frame rates to a select unit at the same time. A compare unit determines whether frequencies of the two state signals are same, so that the select unit determines to forward the base trigger signal or the switch trigger signal to a level shift circuit. Finally, a signal-time control unit controls an output time of the base trigger signal, and controls an output time of the switch trigger signal, so that a liquid crystal unit connected to each gate line has an equal charge time.Type: GrantFiled: August 29, 2014Date of Patent: February 16, 2016Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Yu-an Liu, Liang-Hua Yeh
