Raymond R. Husted has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Reproduction machine with a chain of sorter modules and a method to perform chaining tasks
    Patent number: 4698772
    Abstract: The present invention is a chain of interchangeable control boards controlling the operation of a sequence of sorters. A first control board responds to a sort command. If a first sorter under the control of the first control board is unable to complete the sort operation, a second control board receives a related command. If the second sorter under control of the second control board is unable to complete the sort operation, a third control board receives another related command. Finally, one of the sorters in the chain completes the sort operation and a notification of the completion is carried back up the chain of control boards.

  • Remote processor crash recovery
    Patent number: 4589090
    Abstract: The present invention is a multiprocessor machine control system in which the failure of one of the processors to reset can be ignored by the rest of the control system. In particular, a software crash or other abnormality on one of the processors will generate a reset procedure. If the processor cannot be reset, this will indicate a processor board failure such as a hardware failure. If the processor and its controlled elements are not crucial to the machine operation, then the control wll ignore the failed processor as though it were not in the control system, and continue with machine operation.

  • Control system job recovery after a malfunction
    Patent number: 4521847
    Abstract: The present invention is a multiprocessor control system that allows full job recovery after a machine power down or after a malfunction or software crash or temporary power outage. In particular, essential variables such as the state and status of the machine and the programmed job at the time of the malfunction are maintained in nonvolatile memory. This information is continually updated in nonvolatile memory. Once the control system has reset and reinitialized all the control elements after a malfunction, the control restores or downloads all the relevant variables in the nonvolatile memory to the various control elements to maintain status. In another embodiment, the essential variables are maintained in RAM locations in a master processor and saved for downloading to the control elements.
