Appeal No. 97-0280 Application 08/192,839 and the majority voting circuit will select the output corresponding to these two outputs for transmission to the output terminal 8. In column 2, line 61, through column 4, line 7, Steven discloses an isolating circuit 20 that detects a processor which is producing erroneous outputs at a rate above a first predetermined level and then produces an alarm signal or isolates the processor from the processing arrangement. Therefore, Stevens provides a simple method of isolating the source of errors. On the other hand, Dooley teaches a highly complex signature detecting system for isolating source of correctable errors in a computer system. In column 1, lines 57-62, Dooley teaches that their invention is concerned with maintenance of a computer system constructed of a large number of field replaceable units. Examples of these field replaceable units are edge-connected circuit boards, quick-disconnect cables, rack-mounted replacement boxes and other easily-replaceable components. Dooley teaches in column 5, lines 15-20, that the system provides a signature collection and analysis method which helps field engineers to make more intelligent decisions regarding which field replaceable units is most likely to be responsible for causing an unusual high number of self-correctable errors. We note that Dooley is 6Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
