Abstract: A self-wound, self-adhesive, resealable tamper-evident tape is provided. The tape is used to seal any container requiring a self-adhesive closure, such as bags or pouches, and provides clear visual evidence if the self-adhesive seal is peeled apart. The tape comprises a backing sheet, the upper surface of which is coated with a release layer, and the bottom surface with an adhesive. The release layer is relatively non-adherent to the adhesive so that the tape may be wound or rolled up without a separating liner. A non-visible patterned varnish layer is applied to the adhesive to create a hard surface onto which an colored ink layer is subsequently applied. The colored ink layer breaks or chips when the self-adhesive seal is peeled apart and retains this appearance if the tape is reapplied to seal the container, thereby providing visible evidence of tampering.

Abstract: An exchange reaction of hydroxyl and alkoxysilane is used as a polymerization avenue yielding hyperbranched polymers. A monomer containing hydroxy alcohol functionality and alkoxy functionality attached to a silicon atom in the monomer is employed, and a simple exchange reaction with driving off of alcohol by-product leads to the desired hyperbranched polymerization and materials.

Abstract: Substrates are rendered water repellent by applying to the substrate a hyperbranched polymer containing a silicon atom made by polymerizing a derivatized aminofunctional organosilicon monomer which is the reaction product of an amine functional silane monomer precursor or an amine functional polysiloxane monomer precursor and a derivative of carbonic acid or a cyclic lactone.

Abstract: A microprocessor based instrument designed to retrofit into existing perimeters utilizing the mechanics and stimulus control aspects of the existing perimeter. The device includes an array board positioned adjacent the perimeter mechanical arm and includes a multiplicity of visual indicators spatially arranged in a composite pattern of testing locations required for one or more ophthalmic testing procedures. A processor is connected to the array board for sequentially actuating the visual indicators in accordance with the testing procedure whereby the operator guides a cursor attached to the perimeter mechanical arm to align with the actuated indicators and control the location of the perimeter test stimulus. The processor includes means for sensing the position of the cursor, silently presenting a light flash to the patient, and a memory which records the patient's responses.

Abstract: First and second electro-optical display devices for displaying visual acuity targets, one of which is adapted to be viewed by a patient and the other of which is adapted to be viewed by an examiner. An electronic memory is connected to the display devices containing a plurality of acuity targets stored in various orientations for presentation to the display devices. Controls are provided in an examiner's console for selecting one of a plurality of available target sizes, "zoom" increasing size or decreasing size, selecting a single or a line of multiple target characters, providing normal or reverse video presentation, changing the orientation of the target characters, and providing a blank screen. The size of the targets is varied by changing the dimensions of each of the targets about its own center and in the case of multiple targets, maintaining proportional spacing between the targets as the size of the targets vary.

Abstract: A portable eye examination system cart is provided with an instrument console which conveniently supports eye examination devices, an electric power system effective to provide electrical power to the eye examination devices which are electrical, including automatic turn on and off switches when removing and replacing electrical eye examination devices, and a monitor panel. The electrical system may include a rechargeable battery system and recharging circuitry. The cart includes storage areas for convenient location of ophthalmic drugs and examination supplies, small instrument accessories, spare lamps and parts, patient record charts and other miscellaneous items. The cart includes easily manipulated, lockable covers to secure all instruments and supplies from threat of unauthorized use, and the cart is constructed of lightweight material for good maneuverability with dimensions appropriate for convenient use between hospital beds, movement through hospital corridors, and the like.
