Patent number: 8760750Abstract: The thermally switched absorptive optical shutter may be a self-regulating “switchable absorber” device that may absorb approximately 100% of incoming light above a threshold temperature, and may absorb approximately 50% of incoming light below a threshold temperature.

This has energy-efficiency implications as it can be used to regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. The shutter device has unique optical properties that are not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or other building materials.Type: GrantFiled: April 25, 2012Date of Patent: June 24, 2014Assignee: Ravenbrick LLCInventors: Richard M.

Publication number: 20120154884Abstract: A light quantity adjustment apparatus includes a pair of substrates having a light-path aperture; a plurality of diaphragm blades disposed between the pair of substrates; a driving ring that opens and closes the plurality of diaphragm blades; and a driving device. The plurality of diaphragm blades is supported by the substrate via a first guide plate made of a resin film. The substrate and the first guide plate are provided with guide grooves fitted into protrusions formed in the plurality of diaphragm blades to guide the blades. Guide grooves of the substrate are formed of concave grooves. Guide grooves of the first guide plate are formed of through holes. The through holes of the first guide plate have a narrower width than the concave grooves of the substrate to engage in the protrusions of the diaphragm blades and to guide the diaphragm blades in the open and close direction.Type: ApplicationFiled: October 27, 2011Publication date: June 21, 2012Applicant: Nisca CorporationInventors: Naoto Mochizuki, Kenji Masuyama, Yosuke Sajiki, Takahiro Nishimoto

Patent number: 8184354Abstract: A light-amount adjusting apparatus includes a plurality of light-amount adjusting blades that causes a size of a light-passing aperture to change by rotation thereof. Each of the light-amount adjusting blades includes a base portion on which a rotation center portion and a driven portion are formed, and a blade portion that overlaps another light-amount adjusting blade in a light-passing direction so as to form the light-passing aperture. A thickness of the blade portion is thinner than that of the base portion. When the plurality of light-amount adjusting blades is rotated to set the light-passing aperture to be smaller than a full-opened aperture, a thickness of a portion that overlaps an adjacent stop blade is thinner than that of a portion that does not overlap the adjacent stop blade in each of the light-amount adjusting blades. The blades have high dimension accuracy, and deterioration of the optical performance of the apparatus is reduced.Type: GrantFiled: February 9, 2011Date of Patent: May 22, 2012Assignee: Canon Kabushiki KaishaInventors: Masao Mizumaki, Hiroshi Akada

Patent number: 8169685Abstract: The thermally switched absorptive optical shutter may be a self-regulating “switchable absorber” device that may absorb approximately 100% of incoming light above a threshold temperature, and may absorb approximately 50% of incoming light below a threshold temperature. The shutter may be formed by placing a thermotropic depolarizer between two absorptive polarizers. This control over the flow of radiant energy may occur independently of the thermal conductivity or insulation of the shutter device and may or may not preserve the image and color properties of incoming visible light. This has energy-efficiency implications as it can be used to regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. It also has aesthetic implications since the shutter device has unique optical properties that are not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or walls.Type: GrantFiled: December 19, 2008Date of Patent: May 1, 2012Assignee: Ravenbrick, LLCInventors: Richard M.
