  • Publication number: 20240321163
    Abstract: An information processing apparatus performs face detection processing to detect a face area with a face captured therein from an image captured by an imaging unit, brightness reduction processing in which, when the face area is no longer detected from a state where the face area is detected by the face detection processing while the screen brightness of a display unit is controlled to a first screen brightness, the screen brightness is reduced from the first screen brightness to a second screen brightness after first time has elapsed, and imaging state determination processing to determine whether an imaging state is a first imaging state where the imaging unit can capture an image in an image brightness capable of detecting the face area or a second imaging state where the imaging unit cannot capture any image in the image brightness capable of detecting the face area.

  • Patent number: 8590766
    Abstract: This invention provides a method for inspecting a joined region and joining strength of a joined object formed by a spot friction stir joining process. In this method, an ultrasonic wave is introduced into the joined object from a backing face 25 opposed to a joining tool plunging face 24 and the ultrasonic wave reflected from the joined object 20 is taken in. In this case, the joining region 21 and the joining strength is estimated by observing a reflected wave of the ultrasonic wave in the vicinity of a position, along a reference direction Z, corresponding to an interface 27 of two joining members, without using the reflected wave of the ultrasonic wave reflected from the joining tool plunging face, thereby inspecting the joined object based on the estimation result.

  • Patent number: 6657156
    Abstract: A weld portion detector (20) and a laser beam projector (10) disposed a predetermined distance behind the weld portion detector (20) are moved together. The weld portion detector (20) detects a weld line and the laser beam projector (10) projects on the weld line detected by the weld portion detector (20) for laser welding. Pieces of data on weld positions sequentially detected by the weld portion detector (20) are stored sequentially in combination with times when the pieces of data on the weld positions are obtained and moving speeds of the weld portion detector (20) in a memory. A time when the weld portion detector (20) passed a point at which the laser beam projector (10) has just arrived is calculated on the basis of the times and the moving speeds stored in the memory. The laser beam projector (10) projects a laser beam on a weld position detected at the thus calculated time.

  • Patent number: 6633018
    Abstract: A laser-welding head is capable of applying a fixed pressure to parts to be welded of workpieces regardless of the undulation of the surfaces of the parts to be welded. The laser-welding head includes a pressing device (12) having a roller (16) which rolls along parts of workpieces near a weld line (40) to press together the same parts of the workpieces, a pressing unit (6) for applying a predetermined pressure to the pressing device (12) to press the pressing device (12) toward the parts of the workpieces near the weld line (40), and a laser beam projecting unit (17) mounted on the pressing unit (6) for movement together with the pressing device (12). The pressing unit (6) is provided with a pneumatic cylinder actuator for applying the predetermined pressure to the pressing device (12).
