Patents by Inventor Kouki Uwatoko

Kouki Uwatoko 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).

  • Failure diagnosis method, failure diagnosis apparatus, conveyance device, image forming apparatus, program, and storage medium
    Patent number: 8132049
    Abstract: A failure diagnosis method diagnoses a failure occurring in a diagnosis target apparatus including a drive mechanism having a drive member that receives power supply to operate and a power transmission member that transmits drive force of the drive member to another member. The method includes automatically acquiring by a sensor an operation state signal indicating an operation state during the drive mechanism operating for a predetermined period; and analyzing the automatically acquired operation state signal based on a failure probability model, which is obtained by modeling a cause of failure occurring in the diagnosis target apparatus with using probabilities, to execute failure diagnosis with respect to each of constituent members of the drive mechanism.
    Type: Grant
    Filed: February 23, 2005
    Date of Patent: March 6, 2012
    Assignee: Fuji Xerox Co., Ltd.

  • Failure diagnosis method, failure diagnosis apparatus, image forming apparatus, program, and storage medium
    Patent number: 7243045
    Abstract: A failure diagnosis method diagnoses failure occurring in an image forming apparatus. The failure causes defect in an image output from the image forming apparatus. The failure diagnosis method includes acquiring operation state signals indicating operation states during the image forming apparatus operating in different operation conditions, respectively; and analyzing the acquired operation state signals based on a failure probability model, which is obtained by modeling a cause of the failure occurring in the image forming apparatus with using probabilities, to execute failure diagnosis with respect to each of constituent members constituting the image forming apparatus.
