Abstract: Disclosed herein are systems and related methods for reducing speckle on display screen. More specifically, screen vibration is used to reduce speckle, and in accordance with the disclosed principles, the vibration may be achieved by using wave-based actuation (e.g., acoustic or electromagnetic waves) to vibrate the screen. In an exemplary embodiment, a speckle reducing system may comprise at least one actuating element located proximate to, but not in physical contact with, a display screen. In addition, the at least one actuating element may be configured to generate waves directed towards the display screen. When the waves impact the display screen, the waves impart vibration to the display screen.

Abstract: A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.

Abstract: Directive projection screens described herein are configured to selectively direct incident light depending upon an angle of incidence of the light. Such direction improves projection screen gain. Incident light within an acceptance cone is configured to be presented to a viewer. Light outside of the acceptance cone is directed away from the user or absorbed. As a result of this selectivity and the gain, presentation of images on the directive projection screen is improved in the presence of non-projector light sources.

Abstract: An image forming apparatus performs first control, while rotating an image bearing member at a first speed during non-image-formation, to apply a plurality of alternating-current voltages differing in peak-to-peak voltage to a charging device and to detect the value of each alternating current flowing through the image bearing member. When rotating the image bearing member at a second speed during image formation, the image forming apparatus performs second control, while rotating the image bearing member at the second sped before the start of image formation, to apply an alternating-current voltage determined based on the first control to the charging device. In the second control, the image forming apparatus detects the value of the alternating current flowing through the image bearing member, and determines a peak-to-peak voltage of the alternating-current voltage applied to the charging device at the time of image formation based on the detected alternating current value.

Abstract: A solar light distribution system includes a solar light concentrator that is affixed externally to a light transfer tube. Solar light waves are processed by the concentrator into a collimated beam of light, which is then transferred through a light receiving port and into the light transfer tube. A reflector redirects the collimated beam of light through the tube to a light distribution port. The interior surface of the light transfer tube is highly reflective so that the light transfers through the tube with minimal losses. An interchangeable luminaire is attached to the light distribution port and provides light inside of a structure. A sun tracking device rotates the concentrator and the light transfer tube to optimize the receiving of solar light by the concentrator throughout the day. The system provides interior lighting that uses only renewable energy sources, and releases no carbon dioxide emissions into the atmosphere.

Abstract: An accessory clip is shown which can be used to provide an attachment point for an associated strap for carrying an object by the strap. The accessory clip has a base with an inner planar surface and an outer planar surface separated by a thickness which forms a sidewall for the clip. A bail element is attached to the sidewall and can move relative to the clip base. A carrying strap can be attached to the bail element. The accessory clip has a threaded shaft which extends outwardly from the base inner planar surface. The threaded shaft has a thru bore provided therein which transverses the threaded shaft at a generally right angle thereto, the thru bore being filled with a resilient plastic material which protrudes slightly at either of two opposite ends of the thru bore. The resilient plastic material helps to secure the threaded shaft within a mating threaded receptacle of an object to be carried.

Abstract: A macro photographic apparatus for creating focus stacked images of a specimen may include a rigid longitudinal member having a longitudinal axis and including a camera mount thereon. A translation device may be fixed to the member for translating the specimen along the member toward and away from the camera mount. A rotation device may be mounted on the translation device. The rotation device may support the specimen and enable rotation of the specimen around first and second axes that are perpendicular to the longitudinal axis of the member. At any single position of the translation device along the longitudinal axis of the member, as the specimen is rotated around the first and second axes, the spatial location of the specimen remains substantially the same.

The method includes steps of mechanical slitting of the flexible sheet with a blade, elastic stretch-elongation of the sheet along a direction perpendicular to the slits, and making at least a portion of the sheet elongation irreversible.

Abstract: A rotational shake compensation calculation unit in an image capturing apparatus calculates rotational shake produced by apparatus rotation about an axis orthogonal to an optical axis of an imaging optical system, thereby calculating a compensation amount for image shake. A translational shake compensation calculation unit calculates a compensation amount for image shake resulting from translational shake produced in a travel direction of the apparatus along a direction orthogonal to an optical axis of the optical system. An estimating device estimates translational shake using a vibration model. A translational shake compensation amount calculation unit calculates a translation shake compensation amount based on the estimation amount and varies the translation shake compensation amount in response to the compensation range of the shake compensation unit of the focal distance of the optical system.

Abstract: An anisotropic projection screen accepts light projected at non-normal angles and redirects the light as high quality images along a viewing path that is near normal to the screen. This allows side projection of images in a manner that avoids the potential viewer obstruction of the projection path. The images may be projected onto the screen from any angle (e.g., sides, top, bottom, etc.) relative to the screen surface, and then redirected to the viewer who is viewing the screen essentially normal to the screen surface. The screen has arrays of passive elements that are oriented to collect and redirect light from one direction, while rejecting or absorbing light received from another direction.

Abstract: A method and device for improving natural lighting within buildings is provided. The device comprises a controllable shelf having an upper, specular reflective surface for directing natural light into interior spaces and against interior ceilings. The shelves can be static or pivotable to redirect light based on the day and time of year. The pivotable shelf can be rotated downward or upwards to change the angle with which the light is reflected into the adjacent window, while its position is below the window and along the exterior of the building. This improves interior natural lighting and reduces electrical lighting costs using either a static shelf or movable shelf, wherein the assembly is deployable in a commercial or residential environment without blocking any naturally entering light through the window itself.

Abstract: Systems and methods for improving quality assurance in pathology using automated quality assessment and digital image enhancements on digital slides prior to analysis by the pathologist are provided. A digital pathology system (slide scanning instrument and software) creates, assesses and improves the quality of a digital slide. The improved digital slide image has a higher image quality that results in increased efficiency and accuracy in the analysis and diagnosis of such digital slides when they are reviewed on a monitor by a pathologist. These improved digital slides yield a more objective diagnosis than reading the corresponding glass slide under a microscope.
