5114. Forrester, T. F. May 26. Indicating races.-Ornamental devices, such as crests, monograms, names, &c., are formed on textile or like strips, which are secured to the clothing of racehorses, ponies, or animals engaged in contests so as to indicate the animal and its owner.
Abstract:
A compound polyhedral concentrator (CPOC) lens is disclosed with one smooth curved surface facing the sun and an inner surface comprised of a 3D pattern of interpenetrating minimum deviation prisms with a common origin facing the absorber. This new type of stationary solar concentrator is used to extend the acceptance angles by minimizing blocking and tip optical losses that are common with radial Fresnel design forms. Moreover, when considering the extended time period for non-tracking of the sun's movement commensurate with the increased acceptance angles the total energy collected using a combination of a CPOC lens and a photovoltaic device will be greater than the total energy collected using the photovoltaic device by itself.
Abstract:
The present disclosure reveals a reflective, front-projection screen designed to faithfully and accurately display the images from state-of-the-art (SOTA) and next- generation 2D and 3D motion-picture projectors, such as those found in large-capacity public movie theaters, home theaters, offices, and for use with portable projection systems for consumer and commercial applications. In particular it discloses cinema- size light shaping 3D projection screens with front-surface microstructures and horizontal viewing angles in the range of 90 to 120 degrees.
Abstract:
A method and system referred to as PALM (Patterning by Adhesive of Large Relief Three- Dimensional Micro structures) with large reliefs exceeding 1 µm and being as large as 100 µm. The Micro structures can be either deterministic (such as micro prisms), or random (such as diffusers), the first obtained by copying an original super master, and latter obtained by copying a laser speckle pattern. The master process entails copying a super master into the form of the micro structure constituting a pattern on the patterning cylinder (called a drum), to be then continuously multiplied in the PALM system, in a continuous roll-to-roll web process. The latter method, together with the related system, is the subject of this invention. The rolls continuously repeat the master pattern, copying by adhesive with large viscosity on acrylic (hybrid) as well as by a monolithic process. The monolithic process can be accomplished using temperature and pressure, or by UV-cured polymerization. Therefore, the invention comprises three alternative processes: one, hybrid (adhesive on acrylic), and two monolithic ones. In the PALM (hybrid) process, an epoxy is wet-coated on film substrates such as polycarbonate (PC), polyester (PET), (PE), or other flexible material. The adhesive, in liquid form, is applied to the substrate by a self-metered coating sub-process. In the present invention, the adhesive is used for forming the micro structure pattern. The micro structure pattern is replicated from a master roll or image drum onto a coating roll.
Abstract:
A backlight assembly is provided. The backlight assembly includes a light pipe assembly having a thickness of about 90 microns, a light source and a coupler that receives light from the light source and diffuses the received light from the light source into the first end of the light pipe assembly.
Abstract:
A device and method are provided for delivering three-dimensional (3-D) content. The device includes a receiving unit configured to receive a first signal containing at least two-dimensional (2-D) content. The device also includes a processing unit configured to (i) determine an amount of a difference in the content in the first signal to be visualized by a left visual sensor and a right visual sensor, (ii) determine whether the amount of the difference is less than or equal to a predetermined minimum value, and to discard the signal to be visualized by one of the left visual sensor and the right visual sensor when the amount of the difference is determined to be less than or equal to the predetermined minimum value.
Abstract:
An optical impact system controls munitions termination through sensing proximity to a target and preventing effects of countermeasures on false munitions termination. Embodiments can be implemented on in a variety of munitions such as small and mid caliber that can be applicable in non-lethal weapons and in weapons of high lethality with airburst capability for example and in guided air-to-ground and cruise missiles. Embodiments can improve accuracy, reliability and lethality of munitions depending on its designation without modification in a weapon itself and make the weapon resistant to optical countermeasures.
