    Abstract: A mirror holding mechanism includes: a reflection mirror, a mirror holding member, and a cam member. The mirror holding member has two side surface portions sandwiching the reflection mirror in an X direction. In the side surface portion, a guide hole through which a shaft portion protruding from the reflection mirror to an outer side in the X direction is formed so as to pass through the side surface portion. The guide hole is formed into a long hole longitudinally extending in a Y direction. The cam member is disposed on an outer side of the side surface portion in the X direction and rotatably held by the side surface portion. On the cam member, a cam surface with which a distal end part of the shaft portion comes into contact is formed. When the cam member rotates, the shaft portion moves in the Y direction.

  • Patent number: 10227062
    Abstract: A water-droplet detecting apparatus according to an embodiment includes a setting unit, a first extraction unit, a second extraction unit, and a determination unit. The setting unit sets concentric circles having a center at arbitrary one point of a captured image of an image capturing unit. The first extraction unit extracts candidate pixels based on gradients of pixels on a circumference of each of the concentric circles. The candidate pixels are candidates for pixels that are estimated to indicate a water droplet adhered to the image capturing unit. The second extraction unit extracts one or more candidate circles based on the candidate pixels extracted by the first extraction unit. The one or more candidate circles are candidates for circles that indicate a shape of the water droplet. The determination unit determines whether or not the water droplet is adhered based on an extraction result of the second extraction unit.

  • Publication number: 20140198367
    Abstract: This invention relates to a beam steering mechanism with ultrahigh frequency response and high sensitivity, which is based on the translation of two mirrors. Beam steering is achieved by the translations of two mirrors in the X axial mirror group and Y axial mirror group. The two translation mirrors are located at the output ends of two PZT actuators, and are directly actuated by the two PZT actuators. The dynamic characteristics of the two translation mirrors are always exactly the same as the output characteristics of the PZT actuators. There is no mechanical translation loss in this beam steering mechanism, and so, the beam steering mechanism has an ultrahigh frequency response and high angular deflection sensitivity.

    Abstract: A solar powered rainbow-making device produces a visual display that is created by the interplay of light and a light refractive element that form constantly changing patterns from a rotating crystal. The rotating display device includes a circular-shaped refractive element that is mounted on a base and is turned by a motor driven transmission gear train. The crystal rotates about a horizontal axis as sunlight is transformed into a color spectrum that moves in a circular fashion. The color images can include a plurality of distinct rainbow images that are projected onto the walls and other structures in the immediate environment.
