Kaori Sakagami 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).

  • Peripheral device of programmable logic controller
    Patent number: 8060221
    Abstract: A tracing-result optimization processing unit generates an optimized tracing result. A tracing-result collation processing unit collates the optimized tracing result and a time chart as a basis of a sequence processing for an external apparatus and detects shift of the optimized tracing result. A tracing-result storing unit accumulates and stores therein a tracing result obtained by a programmable logic controller at predetermined time intervals. Every time the tracing result is stored in the tracing-result storing unit, the tracing-result optimization processing unit generates the optimized tracing result.
