Abstract: A sight-facilitating apparatus is provided capable of providing magnifications of about 4X to 8X in an aesthetically pleasing manner. An elongated casing has a light entry at one portion thereof and a light exit at an opposite portion thereof. A prismatic telescopic lens system including an objective, an ocular, and the like is mounted within the casing so that light entering the casing throught the light entry passes through the lens system and exits the light exit, with provision for adjusting the focus of the lens system. The objective is mounted within the casing so that the majority of the focal length thereof extends parallel to the direction of elongation of the casing, the light from the first optical element of the lens system being directed along the direction of elongation of the casing.

Abstract: A field of vision enhancement device having a mounting on an article of headwear adjustable with respect to a straight ahead, normal line of sight including optics for displaying at least one field of optical information either normally occluded by the headwear article or not readily discernable with binocular vision whereby the field of vision is enhanced.

Abstract: A pair of rotatable optical image deflector assemblies are disclosed which are detachably mounted via an adapter bracket to a conventional eye testing apparatus. Each optical image deflector assembly has a fixed light reflecting optical element, and a pivotal reflecting optical element. The optical image deflector assembly directs light onto a peripheral area of an eye, and scans an arcuate portion of the area upon pivotal movement of the pivotal optical element.

Abstract: A method and apparatus is described for modulating a color display in which the blended color is dependent upon the magnitude of N electrical signals which vary with the parameters of an audio signal. Known color pattern generators contain too many variables for a watching subject to be able to correlate them. This invention displays a single blended color which is related to the characteristics of the sound input.

Abstract: An optical device for mounting either a mirror or magnifying lens at a predetermined position in front of a wearer's eye which permits the mirror or lens to be adjusted to variable operative positions, the device includes alternative connectors for permitting it to be mounted on the wearer's eyeglass frame or on the rim of a safety helmet.

Abstract: A device for producing images of a plurality of speech information symbols associated with speech sounds produced by a speaker into the field of view of a hearing-impaired person with one or more light emitting or illuminated arrays mounted paraxially with the viewer's line of sight on a transparent plate which subtends and mounts an adjacent eyeglass lens. A mirror is mounted on the lens to produce a magnified image in the field of view and reflect the image back to the viewer. The interior surface of the lens may be coated to form the mirror or spherical dimples may be ground into the surface before coating and the coated dimples then filled with a material having substantially the same refractive index as the lens.

Abstract: A rear view mirror for being personally worn by a user; the mirror including a clip for attachment either to the person's eyeglasses, hat, helmet, shoulder or the like, and a universal joint between the mirror and clip, for directionally aligning the mirror.

Abstract: A rear view vision mirror attached to a pair of spectacles.

Abstract: A removably mounted, slidably engagable, pivoting rear view mirror attachment for use on the temple portion of most conventional eye glasses.

Abstract: An eyeglass frame fitted with mirrors so as to direct the vision from each eye to a different point when both eyes are similarly focused. Each of the two lens frames of the unit are mounted by a hinge to a bridge joining the two lens frames, and each temple of the unit is fitted by a turnbuckle to the side of one lens frame. A pair of mirrors are pivotally mounted to each lens frame with each mirror fitted to an axle that is rotatably mounted to the frame and with both axles being mounted along parallel axes. The mirrors are oriented so that the first mirror of each set reflects light to the eye from the surface of the second mirror of the set, which second mirror is set to reflect from in front of the observer to the first mirror.

Abstract: A rear-view mirror assembly for mounting on various types of apparel such as the frame of eyeglasses, the peak of a cap, a helmet, etc is disclosed. The device includes a body which has an attachment member at one end thereof. A U-shaped mirror supporting arm is provided having a ball and socket connection at the end of one arm of the U-shaped arm swivelly connected to the end of the body member. The other arm has a ball and socket connection with a mirror mounting device in which is mounted a mirror.

Abstract: A personal information system wherein an illuminated information source is viewed in a mirror located closer to the eye than the shortest focal length to present in focus a visual image to the eye so that it can be viewed unobtrusively superimposed over the existing visual scene during normal activities. In a further aspect, the invention provides reflected illuminated symbolic presentation for speech interpretation assistance.
