Miki Tobita 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: 10391629
    Abstract: An air pump apparatus is provided which uses an electric actuator that can electrically operate a pneumatic device such as a suction pad or air chuck. The air pump apparatus includes an air cylinder having a built-in piston, and an electric actuator configured to move the piston linearly and relatively to the air cylinder, using the electric motor as a drive source. Air under negative pressure and/or positive pressure generated by the electric actuator causing the piston of the air cylinder to move linearly is used to operate a pneumatic device.
    Type: Grant

  • Patent number: 7984590
    Abstract: At both sides of a pair of doors 10L, 10R, a pair of television cameras (two-dimensional image sensors) 18A, 18B for detecting a moving object, and a pair of spare infrared ray sensors 20A, 20B are provided. A central control unit 16 calculates the position and moving direction of moving object by image processing of outputs of television cameras 18A, 18B, and predicts the passing position of moving object on the vertical plane P when the moving object approaches, thereby calculating the target opening degree of a pair of doors 10L, 10R individually, and determines the target opening degree of doors in full closing when the moving object leaves away, and thus outputs move command signals to motor controllers 14L, 14R so that the pair of doors 10L, 10R may be set at the target opening degree.

  • Publication number: 20060105338
    Abstract: There is provided a method of correcting position and attitude of an object to be held capable of reducing the number of image processing steps and simplifying the method of correcting shifts in the position and attitude of the object with respect to a holding member. The object to be held is detachably held to the holding member and a fiducial mark 1 and a fiducial mark 2 are applied to the object. First, the fiducial mark 1 is subjected to an image processing so as to obtain position data of the fiducial mark 1 (S2). Next, the holding member holding the object to be held is rotated substantially by 180 degrees in a horizontal plane (S3). Then, the fiducial mark 2 rotated by 180 degrees is subjected to an image processing so as to obtain position data of the fiducial mark 2 (S4).
