20090097142 | FACETED MIRROR APPARATUS - A faceted mirror apparatus includes a support plate having a plurality of stepped reception bores into which are fitted the base portions of respective ones of a plurality of mirror facets having mirrored surfaces. An outer surface of each of the facets bears on an inner wall to provide a stable alignment of the optical axes of the mirrored surfaces such that the apparatus generates a beam of rays from impinging rays. | 04-16-2009 |
20090174957 | Polarization Linkage of High Dielectric Constant Pivoted Planar Solar Concentrator Mirrors - This invention deals with novel method and apparatus for highly polarizable high dielectric constant positioning and motion control of the elements (approximately planar mirrors) of a Fresnel reflector solar concentrator tracking heliostat array wherein the elements are suspended with the center of mass above the swivel point, below the swivel point, or have an internal-swivel. This achieves an advantageous natural vertical stability. The torque to produce angular deflection, and rotational motion is provided induced and/or permanent dipole coupling to an electronic grid. The force interaction is greatly enhanced by securing a high dielectric material adjacent to each mirror. Thus forces and torques are produced without the use of motors. The instant invention is ideally suited for maximization of solar energy focused by a low-profile concentrator array onto a receiver. Since there are no motors or mechanical linkages, the instant invention provides less costly and greater ease of manufacture. Dynamic motion can be controlled over a wide range of dimensions from nanometers to decimeters. | 07-09-2009 |

20100177415 | REAR-VIEW MIRROR FOR IMPROVING A DRIVER'S VISION IN A CAR OR MOTOR VEHICLE - The invention relates to a rear-view mirror for improving a driver's vision in a car or motor vehicle. As with standard rear-view mirrors, the inventive dual rear-view mirror, which is positioned inside the vehicle, displays an image of the area to the rear of the vehicle in terms of real distance. According to the invention, the rear-view mirror is articulated with the left mirror which displays the real distance of the external right-hand side area, thereby ensuring safety. It is important to note that the technical-industrial process used to develop the aforementioned dual mirror retains the same technical production principles used in the automotive field since the invention makes use of PVC injection and moulding processes and the huge variety of features offered by plastic materials in this sector for use in structures and joints which are pressure mounted for the above purpose. | 07-15-2010 |

20110235201 | TWO-IMAGE-POINT IMAGING OPTICAL DEVICE - A two-image-point imaging optical device forms a real image in space on the same side as a point light source with respect to one plane on the device and a virtual image in space on the opposite side. In the two-image-point imaging optical device, multiple dihedral corner reflectors each comprising two mutually perpendicular planar specular surfaces are so disposed that the line of intersection between the two specular surfaces of each dihedral corner reflector is parallel with those of the others on a first plane. A virtual image is formed in space on the side opposite to the point light source which the two specular surfaces face with respect to the first plane and a real image is formed in space on the same side as the point light source. This enables the virtual and the real images that lie on a straight line to be observed from a viewpoint in the space on the same side as the point light source. | 09-29-2011 |
