Abstract: A single camera autostereoscopic recording system includes a single image recorder having a single optical path moved along the scanning path substantially continuously for a plurality of scanning cycles. A path defining structure includes the ability to adjust the convergent point as well as the extent of travel along the scanning path or disparity of the images. The convergent point of the scanning path can be manually or automatically adjusted using a range finder. A unique driver structure provides scanning motion with reduced reactional forces. The degree of motion of the recorded images is used to adjust the amount of travel along the scanning path. Synchronization between the driver and the recorder is bi-directional for double exposures. The recorded image is adjusted in recording or in display as a function of the position in the scanning path.

The spirit level is mounted on a bottom portion of the relector.

Abstract: An inspection apparatus for internally inspecting tubular members has a body having an inspection window. Located inside the body is a camera, a laser and associated reflectives, one of the reflectives being rotatable by a motor such that a beam of light is directed through the window to illuminate an axial extending strip of the entire 360.degree. interior circumference of the tubular member. Light is reflected from the window and the tubular member to be focussed onto the camera lens. The images reflected by the window and the tubular member interior surface are correlated so that, for example, ovality of the tubular member may be detected. The data may also be compared with data stored in a computer.

Abstract: A process and an apparatus for treatment of an analog electric signal, in particular the image signal of bar codes, for obtaining a parametrable binary signal, the process comprising storing certain non-linear filtering parameters (MP) and, after having converted the analog signal into a digital signal (CAN), detecting sequentially the successive extremums of said digital signal (PIC) by an iterative treatment while considering said parameters, and then carrying out in each sequence a sigmentation treatment (BIN) by the detection of each extremum, for extracting and storing (RAM) the length of the representative segments of the succession of extremums.

Abstract: An apparatus for evaluating the alignment of both eyes of a patient objectively in primary, secondary and tertiary gaze, and the Bielschowsky head tilt positions and to diagnose for phorias, tropias and intermittent tropias. The apparatus has a head restraint and a mounted fixation target in a spaced relationship to the head restraint and having adjustments for adjusting the target along three axis. Electronic shutters are used to occlude each eye during the testing. A camera is used for imaging the eye of a patient having his head in the head restraint with his eyes aligned with the target. The camera is mounted adjacent to the target on the xyz mount.

Abstract: An apparatus and a method for assisting in the selection of corrective lenses includes a spectacle frame having at least one test mounting lens emplaced in the eyepiece of the frame. The test mounting lens has a horizontally elongated aperture for releasably and slideable receiving a telescope holder therein. The telescope holder releasably retains a telescope within it and rides in the slot for positioning the telescope in a position that allows a person being tested to see through the telescope.

Abstract: A method and apparatus (2) for inspecting the surface quality of automotive parts (38) having smooth surfaces (44) utilizes a light source (4) and diffusing surface (6) contained in an opaque enclosure (8). The diffusing surface has a convex shape and is arranged relative to the light source to direct a gradient of light through the aperture (10) in the form of a beam. An object to be inspected is placed in the beam at a low angle relative to the inspection apparatus. All extraneous light is controlled and the beam is reflected off the object to an observer. The gradient in the reflective beam exposes any defects on the surface that are located on the beam and the location of the defects is noted. The inspection system and method can be used to inspect objects having surfaces that range from being highly reflective to lowly reflective. The curvature and location of the diffusing surface within the enclousre is adjustable. The size and location of the aperture is also adjustable.

Abstract: An appliance for sterilizing contact lenses or the like includes a reaction vessel for containing the lenses in sterilizing contact with hydrogen peroxide solution and two catalytic elements for decomposing the hydrogen peroxide during the lens sterilization. The first catalytic element decomposes a portion of the initial concentration of hydrogen peroxide in the solution during the lens sterilization, and the second catalytic element accelerates combined decomposition of the reduced concentration of hydrogen peroxide in the solution resulting from decomposition by the first catalytic element, in order to achieve sufficiently reduced terminal hydrogen peroxide concentration at completion of the lens sterilization for safe contact by the eyes of a wearer with residues of hydrogen peroxide at the terminal concentration which may adhere to the sterilized lenses.

Abstract: A magnifying assembly of the type employing a lens surrounded by a plastic or metal holding is placed in a light diffuser, which light diffuser is an annular member having an open top which is associated with a peripheral flange upon which the magnifying lens rests. The member has a bottom opening which is associated with an annular curved flange which is abraded so as to uniformly diffuse light over the surface of a document to be read whereby the area enclosed by the bottom opening of the annual member is uniformly illuminated by a light source.

Abstract: A motor vehicle headlight of the type comprising a lamp having a filament (100), a reflector (200) defining an optical axis (Ox), and a closure glass (300), the filament emitting light freely in all radial directions thereabout and the reflector having a smooth and essentially continuous reflecting surface which reflects the rays emitted by the filament in such a manner as to cause the majority of them to be situated beneath a cut-off (hHc; hh) constituted by two half-planes of given height and slope.

Abstract: A process for releasing leachable substances from a polymeric contact lens blank. the contact lens is confined in a cavity within a carrier to permit the hydration of the lens without permitting it to invert or roll over. A fluid flow is introduced into the cavity about the lens to extract leachable material from the lens. The process significantly reduces the amount of leaching fluid that is used and the amount of time that is needed for hydration, washing and extraction.

Abstract: Compact night vision goggles apparatus (400, 500, 600) which provide the user with both a direct or unintensified image and an intensified image via first and second intersecting optical paths. The apparatus includes secondary image input means (490, 690) for incorporating symbology or other secondary images into the intensified optical path to be presented to the user along with the intensified and unintensified images. In addition, the apparatus includes peripheral imaging means (540) for providing the user with a large peripheral field of view notwithstanding obstructions on the apparatus which would normally interfere with the user's peripheral vision.

The spirit level is situated outside the housing, at least in part.

Abstract: An electronic gaming system for playing games which includes a system base station and a plurality of gaming boards. The system base station downloads game instructions, a game schedule, and game card arrays into the gaming boards. These game card arrays are stored in the system base station as a gaming card library. The gaming card library contains a plurality of game card arrays such that no two arrays are identical. Each game card array is stored as a single record containing the elements of a particular array, while the individual enjoys instantaneous access to a plurality of gaming cards. The game schedule stores symbols which are to be matched with randomly generated symbols, particularly where the symbols are numbers and the pattern is a plurality of elements of a 5.times.5 array. The base station employs an algorithm to generate cards which ensures that numerical arrays of consecutive adjacent gaming arrays in said library differ by more than one array entry.
