Abstract: A method for diagnosing and treating urogenital disorders associated with atrophic vaginitis in symptomatic women having vaginal pH of 4.5 or above allows documentation of symptoms, justifies estrogen use and can be used to determine the duration of treatment. The method includes measuring and recording vaginal pH, and intravaginally administering a dose of estrogen using a prefilled applicator. The applicator comprises an elongated curved tubular reservoir for containing a gel, cream or ointment, and a plunger, sealingly seatable within the reservoir and operable to displace estrogen gel, cream or ointment therefrom. The outside diameter of the reservoir ranges from 0.25 to 0.375 inches.

Abstract: A laser driven optical communication apparatus for permitting verbally impaired or disabled individuals having limited physical mobility to communicate with others. A laser device generating a coherent beam of light is provided wherein the individual directs the beam of light upon an interface screen towards forming images understandable by others. The interface screen serves to cause the beam of light to be reflected and made visible. An optical receiver comprising a modified video camera directed toward the interface screen receives the reflected image and serves to enhance the persistence of the image to cause the beam of light directed by the individual to appear as a single continuous image upon an associated display. A video cassette recorder may be incorporated to permit the images to be stored and replayed at a later time. The present invention may also be used to permit a speaker to "draw" images upon a display being projected upon a display screen such as in a conference hall setting.

Abstract: An improved laser pumping apparatus in which a plurality of generally spherical beads are disposed in pumping energy transmitting juxtaposition with the active outer surface of a laser element so as to be positioned between the active outer surface of the laser element and a pumping energy source. in a neodymium doped yttrium aluminum garnet laser element pumped by a flash lamp, the beads are made of silicon. The beads are approximately 50 to 100 microns in diameter and may be attached directly to the active outer surface of the laser element, such as by using a pumping energy transmitting adhesive, or the beads may be attached to an intermediate transparent or translucent pumping energy transmitting member such as a thin sleeve that fits over a laser element configured as a rod.

Abstract: A three-dimensional laser driven display apparatus for the controlled projection and manipulation of laser generated images toward the creation of a three-dimensional display. The apparatus comprises an image signal generator, raster generator, laser beam generator and a varifocal mirror wherein the image signal generator and raster generator spatially encode the laser beam image. The laser beam is reflected by the raster generator onto the varifocal mirror, the vibration of which serves to spatially decode the laser beam image whereby a three-dimensional image is viewable projected in space standing off of the surface of the varifocal mirror. The interposition of an imaging surface between the raster generator and the varifocal mirror causes the three-dimensional display to be viewed directly upon the surface of the vibrating varifocal mirror.
