Patent number: 9523759Abstract: The invention is a system and method for heliostat mirror control. Here, each heliostat mirror generates a low intensity “signal beam”, directed at an angle off from the heliostat mirror's high intensity and sensor blinding “main beam” of reflected solar energy. The low intensity signal beams may be created by reflecting a small portion of the incident solar light at an angle from the main beam, by reflected artificial light, or from lasers shinning onto mirrors from known locations. The signal beams are detected by optical sensors mounted way from the main heliostat receiver focus, and can be used in a closed loop control system to efficiently ensure that individual heliostat mirrors in a heliostat array accurately track sunlight and direct the sunlight to a central receiver. Because heliostat mirrors need not be taken “off sun” for positioning, the system allows heliostat arrays to be run at high efficiency.Type: GrantFiled: April 2, 2015Date of Patent: December 20, 2016Assignee: IDEALABInventor: William Gross

An electronically activated material layer is disposed above the front display surface to substantially cover at least an active display area of the multilayer display portion in which the electronically activated material layer is integrated with the multilayer display portion and activation of the electronically activated material layer alters the native viewing angle. A touch screen portion is disposed above the electronically activated material layer. The touch screen portion is configured to at least react to touch inputs from a user and to substantially cover the active display area.Type: ApplicationFiled: May 14, 2012Publication date: November 14, 2013Inventor: Marcus Bulda

Publication number: 20130279011Abstract: An automatic transaction apparatus (12) has an input unit (18) for entering information and a private view protector (20) including an upper surface member (32) covering the input unit (18) from above. The private view protector (20) has an upper surface member (32) having tilted surfaces formed juxtaposionally thereon. The tilted surfaces are tilted more mildly as away from the operator (22) on the input unit (18) to form a slit member (24) having openings formed. Light fluxes (26, 28) from the input unit (18) are directed to the operator (22) so as not to reach a monitoring camera (14). That prevents the input unit from being visible from above while enabling the operator to view the input unit.Type: ApplicationFiled: April 10, 2012Publication date: October 24, 2013Applicant: OKI ELECTRIC INDUSTRY CO., LTD.Inventor: Akira Kubota

Patent number: 8529075Abstract: An antireflection structure having a high antireflection effect is provided. An antireflection structure (50) reduces reflection of light having a wavelength equal to or larger than a predetermined wavelength, and absorbs the light whose reflection is reduced. The antireflection structure (50) includes a base structure portion (7) which is configured to have a plurality of structural units (70) arranged on a reference plane, and each having a tilted surface (71) so that an angle between the first side surface (71) and a reference plane (51) is a predetermined angle, and a plurality of fine concave/convex portions (8, 8, . . . ) which are formed on a surface of the base structure portion (7), and arranged within a cycle equal to or smaller than the predetermined wavelength.Type: GrantFiled: September 3, 2008Date of Patent: September 10, 2013Assignee: Panasonic CorporationInventors: Kazuhiro Yamada, Takamasa Tamura, Yasuhiro Tanaka

Patent number: 8449166Abstract: An image source unit that can efficiently provide image light emitted from an image source to an observer is disclosed. The image source unit includes an image source; and an optical sheet that disposed closer to an observer side than the image source. The optical sheet includes an optical functional layer that includes a light-transmitting portion having a trapezoidal cross section; and the low refractive-index portion having a wedge shape cross section. An oblique side of the wedge shape cross section of the low refractive-index portion form an angle of ?b with respect to a normal line of the sheet surface.Type: GrantFiled: December 22, 2010Date of Patent: May 28, 2013Assignee: Dai Nippon Printing Co., Ltd.Inventor: Tsuyoshi Kashiwagi

Patent number: 8405895Abstract: An optical system is disclosed that includes a housing that has an interior, a reflective interior surface, and a first opening. The optical system further includes a spatial light modulator that is disposed proximate the first opening and a light source that is disposed within the interior of the housing. The spatial light modulator modulates the light that is emitted by the light source to form image rays. The optical system further includes a first light redirecting film that is disposed proximate the first opening between the spatial light modulator and the light source. The first light redirecting film recycles at least a portion of the light that is emitted by the light source. The optical system further includes an optically absorptive film that is disposed proximate the first opening between the spatial light modulator and the viewing position. The optically absorptive film receives the image rays from the spatial light modulator and displays the received image rays to the viewing position.Type: GrantFiled: November 10, 2008Date of Patent: March 26, 2013Assignee: 3M Innovative Properties CompanyInventors: Guido Hitschmann, Kay-Uwe Schenke
