A controlling light source (20) illuminates the photoconductive substrate (14) in correspondence of an active region, wherein the light source is arranged for selectively illuminating the substrate (14) by emitting at least an optical beam (B) adapted to generate in an area of the substrate (14) a local electrical charge density proportional to the spatial light intensity of the beam (B) and responsible for a local deformation of the membrane structure (10).Type: ApplicationFiled: October 30, 2009Publication date: August 30, 2012Applicant: Consiglio Nazionale Delle RicercheInventors: Stefano Bonora, Stefania Residori, Umberto Bortolozzo

Patent number: 8220965Abstract: A laser device including a concave mirror converging beamlets from a plurality of high efficiency diode lasers to a focal point, an integrating convex mirror placed at or near the focal point reflects a first portion of the beamlets back to the concave mirror and allows a second portion through to a light transmitter. The second portion of beamlets exists the light transmitter as a homogenized uniform laser beam having substantially uniform convergence and focus.Type: GrantFiled: April 20, 2010Date of Patent: July 17, 2012Inventor: Martin A. Stuart

Patent number: 8157397Abstract: A foldable reflector screen includes a flexible, cloth-like reflective element having an inside and an outside, a supporting and tensioning structure arranged to support the reflective element on the outside, and a carrier element including at least one lamp and mounting the supporting and tensioning structure. The reflector screen has an open state in which the reflective element forms an essentially rotationally symmetrical body having an axis of rotation and has a light outlet opening. The reflective element comprises at least two reflective sections. The two reflective sections have in each case a different geometrical shape in a section containing the axis of rotation of the reflective element.Type: GrantFiled: June 25, 2008Date of Patent: April 17, 2012Inventor: Hans-Werner Friedrich Briese

Patent number: 8157404Abstract: A visible light transporter (1) having a carrier (25) for holding a plurality of lighting devices (L1 through L4). The lighting devices frequently employed as road flares emit a light usually concentrated into a horizontal light beam (HB) and pulsing. Carrier (25) has body 9 constructed of a light transmitting resin which permits light from the held lighting devices to be transmitted with attenuation through body 9 of the carrier. Carrier (25) also includes openings (01 through 04) which permit lighting devices (L1 through L4) to be removeably installed in pockets (S1 through S4) provided for holding the lighting devices. Openings also permit some light to pass unattenuated exterior to carrier (25).Type: GrantFiled: June 22, 2009Date of Patent: April 17, 2012Inventor: Kevin F McDermott

Patent number: 8002430Abstract: One embodiment relates to a portable article illumination system with an enclosure disposed between openings in the interior and external surfaces of a portable article. A removable illumination device may be disposed within the enclosure such as a selectably engageable portable lighting device. The interior and exterior openings may each be substantially covered by transparent and opaque members respectively. The transparent members cover the interior and exterior openings and are disposed proximal to the enclosure with respect to the opaque members. The transparent members may further provide optical pathways between the enclosure and the interior and/or exterior region. The opaque members substantially cover the transparent members thereby optically obstructing the optical pathways which extend from the enclosure through the corresponding transparent member to the interior or exterior region.Type: GrantFiled: April 17, 2009Date of Patent: August 23, 2011Assignee: Tactical Lighting Solutions, LLCInventors: Greg Kennedy, Douglas Kennedy

Patent number: 7993029Abstract: A backlight module includes a light guide plate and a flexible, looped strip. The light guide plate includes a light emitting surface for emitting light outwardly therefrom. The strip loop includes a brightness enhancement portion and a light-pervious base portion connected end to end. The strip loop is rotatable relative to the light guide plate such that the brightness enhancement portion and the light-pervious base portion can be selectively aligned with and face towards the light emitting surface. The light guide plate is positioned between the brightness enhancement portion and the light-pervious base portion.Type: GrantFiled: May 21, 2009Date of Patent: August 9, 2011Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Han-Lung Lee

Publication number: 20100232161Abstract: An optical apparatus includes a first membrane, a second membrane and at least one electromagnetically displaceable component. The first membrane includes an optically active area. The first membrane and the second membrane are coupled by a filler material disposed in a reservoir. At least one electromagnetically displaceable component is coupled to the filler material via the second membrane, such that a displacement of the at least one electromagnetically displaceable component is operative to cause a deformation of the optically active area of the first membrane by movement of the filler material.Type: ApplicationFiled: March 9, 2010Publication date: September 16, 2010Inventors: Manuel Aschwanden, David Niederer, Thomas Schmidhausler, Christoph Romer, Thomas Kern, Shu-Heng Yang, Charles King, Dennis Ray Kirchhoefer, Daniel Warren

Patent number: 7780303Abstract: An apparatus and methods that includes a gel holder and an optional shade holder that allows a user to add color or eliminate or reduce reflected color and to shape, shade, diffuse, soften, absorb, block, reflect, retract and dim light inside photographic reflectors such as photographic umbrellas or other reflective apparatus. The invention allows a user to mix, blend or shape light at the source and the resulting light can be symmetrical or asymmetrical. The invention allows a user to more efficiently add texture, eliminate hotspots and create shadows by changing positions of a gel holder with a gel and one or more shade holders with shades on a reflector focus tube.Type: GrantFiled: November 8, 2007Date of Patent: August 24, 2010Inventor: Sergio Alejandro Ortiz-Gavin
