  • Robot and emergency stop method of robot
    Patent number: 9548168
    Abstract: A robot includes a power source of the robot, and a switch section adapted to block electrical power supply to the power source. The switch section is disposed on a front side of the robot arranged to face to a workbench when at work. The switch section blocks the electrical power supply to the power source in a case in which it is detected that a distance between the robot and the workbench is longer than a predetermined distance.
    Type: Grant

    Date of Patent: January 17, 2017
    Assignee: Seiko Epson Corporation
    Inventors: Kaoru Takeuchi, Tatsuya Matsudo
  • Intrusion detection device, robot system, intrusion detection method, and intrusion detection program
    Patent number: 9131121
    Abstract: An intrusion detection device includes: a light emitting unit which forms a plurality of light emitting marks arranged on a boundary of an intrusion monitoring area; an imaging device which images an area including the plurality of light emitting marks, and outputs the captured image; and a detection unit which detects predetermined marks which are different from the light emitting marks, from the output image, sets a masking area on the image based on the detected marks, and detects an intrusion material in the intrusion monitoring area based on the image in an area other than the masking area.

  • Circuit for comparison of signal voltage with reference voltage
    Patent number: 5994927
    Abstract: A circuit includes a middle-voltage-detection circuit which detects a substantially middle voltage between a HIGH level and a LOW level of a signal voltage, and supplies the substantially middle voltage as a reference voltage. The circuit further includes a differential amplifier which receives the signal voltage and the reference voltage.
