Yoshikazu Kushimoto 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).

  • Detecting a deflated vehicle tire by comparing angular velocity data of all wheels, a data table, and the directly-measured pressure of a single tire
    Patent number: 5524482
    Abstract: A method for detecting a deflated condition of a tire, comprises the steps of: detecting the angular velocity of each wheel, producing a signal proportional to the angular velocity detected, directly detecting the pneumatic pressure of a tire for only one wheel, producing a signal proportional to the pneumatic pressure detected, and arithmetically processing the signals produced in the preceding steps. A device to which this method is applied is also disclosed.
    Type: Grant
    Filed: July 20, 1995
    Date of Patent: June 11, 1996
    Assignee: Sumitomo Rubber Industries, Ltd.
    Inventors: Yoshikazu Kushimoto, Minao Yanase
