Patents by Inventor Tetsuyou WATANABE

Tetsuyou WATANABE 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).

  • Patent number: 10685450
    Abstract: A controller controls operation of a forming machine capable of forming a workpiece. The controller includes: an object determination unit configured to determine an object other than the workpiece and the forming machine based on image data sensed by a sensor; a setting unit configured to set a plurality of determination areas based on a bolster shape of the forming machine included in the image data; a detection unit configured to detect entry of the object into each of the plurality of determination areas set by the setting unit; and a control unit configured to limit operation speed of the forming machine based on the determination area in which the entry of the object has been detected by the detection unit.
    Type: Grant

  • Patent number: 10380732
    Abstract: A system controller serving as a controller for controlling a forming machine acquires, from a sensor which outputs image data for determining a distance in a height direction by sensing a predetermined area including a machining area of the forming machine, background image data not including an image of a workpiece and an operator of the forming machine, and current state image data representing a current state of the predetermined area during operation of the forming machine. The system controller calculates difference data indicating a difference between the background image data and the current state image data, and determines an area of the operator in the predetermined area based on the difference data. The system controller controls operation speed of the forming machine based on a result of the determination.
