Remote Multiplexer Terminal With Redundant Central Processor Units
US Patent:
4610013, Sep 2, 1986
Filed:
Nov 8, 1983
Appl. No.:
6/549776
Inventors:
James R. Long - Huntsville AL
Roy L. Harrill - Walton Beach FL
Roy L. Harrill - Walton Beach FL
Assignee:
Avco Corporation - Huntsville AL
International Classification:
G06F 1120
US Classification:
371 9
Abstract:
An approach is disclosed for accomplishing redundancy in the central processor units of a remote multiplexer terminal (RMT). Through execution of a stored software program the RMT receives data from input/output devices, processes that data and transmits it to external equipment. The system uses two central processor units (CPU's), each with its own input/output (I/O) bus. Both CPU's actively and continuously monitor the status of the I/O subsystems. The software program designates one CPU as the "Master", the other CPU as the "Slave". The CPU designated as "Master" performs active control functions so long as error detection circuitry within each CPU determines that the operational status of the "Master" is good. Error detection is accomplished by incorporation of a "Watch Dog Timer" in each CPU. A failing CPU is redesignated to be a Slave (and is halted) and the previously designated Slave CPU is redesignated as a Master.
Programmable Binary Counter
US Patent:
4158767, Jun 19, 1979
Filed:
Apr 24, 1978
Appl. No.:
5/898904
Inventors:
James R. Long - Huntsville AL
Assignee:
Avco Corporation - Huntsville AL
International Classification:
H03K 2136
US Classification:
235 92PE
Abstract:
This invention concerns a programmable counter which can be preset to provide an output indication one pulse after the count of the incoming signal pulse train has reached the integer M, where M equals any binary real number over the range (0, 1, 2, 4, 8, 16,. . . , 32,768). The programmable counter can be preset to any one of the binary numbers using a 4 digit word.
