  • Patent number: 6554444
    Abstract: A gazing point illuminating device is provided with: a light source; a direction changing mechanism for changing the lighting direction of the light source; a gazing direction detector for detecting the direction of the user's gazing line; and a controller for changing the lighting direction corresponding to the detected gazing direction. When, LEDs are used as the light source, and the light source is attached to the goggles worn by a user, the goggles can be useful gazing point illuminating device by themselves even if they do not include gazing point or direction detectors, because a person normally look straight ahead except for unusual occasions where he/she purposefully avert his/her gaze. Thus, an illuminating device fixed to a person's head for lighting forward is a gazing point illuminating device. It is preferred to provide an LED panel at the left and right ends of goggles.

  • Patent number: 6530677
    Abstract: A method and apparatus for instructing a procedure for manufacturing a wire harness are provided. A plurality of work positions is simultaneously illuminated with the visible light, and a procedure related to each work position is displayed with an optical image formed by scanning the work positions. Optical images may be consecutive numerical values formed of the visible light in correspondence to the order of works, or an outline drawing G of the wire harness WH may be displayed with an optical image formed of the visible light. Thereby, it is possible to display the order of stages without detecting the progress of an operator's work one by one. Further, utilization of the optical image allows the order of stages to be recognized easily and prevents errors from being made. Furthermore, a first holder pivotally holds a light source on a first axis. A light source-driving member for pivoting the light source on the first axis is provided on the first holder.

  • Patent number: 6527407
    Abstract: A system for the protection of airport runway light fixtures and markers is disposed at or near the edge of aircraft runways, taxiway and airport signs. The system includes a thin flexible mat having an axial opening proportioned to enable placement of a runway light fixture or marker therethrough; and peripherally disposed apertures within the mat. The system further includes several anchors for the mat, each of which comprise a planar head, and means for penetration and engagement of earth upon which the mat is positioned. The penetration and engagement elements of each anchor integrally and rigidly depend from a lower surface of the planar head at a central axis. A greatest transverse cross-section of the engagement element is proportioned for complemental insertion within the peripheral apertures of the convex mat. The planar heads of the anchors each engage the mat when the engagement means have fully penetrated the earth upon which the mat is to be secured.

  • Patent number: 6527425
    Abstract: A first reflection surface of a reflector is set up for a first brightness-intensity distribution pattern to be projected through a flat lens to conform to a target brightness-intensity distribution pattern. A displacement between the target brightness-intensity distribution pattern and a second brightness-intensity distribution pattern is calculated, the second brightness-intensity distribution pattern being reflected by the first reflection surface and to be projected through a curved lens. A second reflection surface of the reflector is set up for the displacement to become substantially a zero.
