Abstract: A surgical instrument for removing a cataract from a patient's eye including a hollow vibrating needle surrounded by two hollow infusion sleeves. The outer sleeve conforms to the incision in the eye and the inner sleeve prevents the outer sleeve from collapsing onto the hollow, vibrating needle.

Abstract: A pair of non-prescription eyeglasses is mounted on a cantilevered support by a hanger that includes an element constructed of relatively stiff resilient plastic material. Such element includes a relatively wide main section having an aperture which receives the support arm, and a relatively narrow extension. The latter passes through the nose gap of the eyeglasses and is reversely bent to form a loop that surrounds the eyeglass frame bridge. In a first embodiment of this invention a rivet maintains the loop closed and prevents casual removal of the hanger from the eyeglasses. In a second embodiment a snap-type device holds the loop closed. This snap-type closure cannot be opened casually, at least for the first opening thereof.

Abstract: A magnifying device that can be attached to a retail store shelf where a product on the shelf, such as a can, a medicine bottle, etc., can be placed beneath the magnifying glass of the magnifying device so that the small print contained on the label of the product can be read.

Abstract: A muscle exercise and rehabilitation apparatus including a patient chair having a first side and a second side is disclosed. Structure is provided for the rehabilitation and exercise of a patient seated in the patient chair. Structure is provided to move the rehabilitation and exercise structure between a first position adjacent the first side of the patient chair and a second position adjacent the second side of the patient chair in a first linear path. Structure is provided to support the patient chair for movement along a second linear path toward and away from the exercise and rehabilitation structure.

Abstract: Optical transceiver apparatus for detecting angular misalignment between a pylon and fuselage of a helicopter, includes an optical transmitter secured to one of the pylon and fuselage and which transmits three spaced optical beams; an optical receiver which receives the optical beams from each optical transmitter, the optical receiver being mounted on another one of the pylon and fuselage, the optical receiver including a two linear detectors which detects angular twist between the pylon and fuselage from a null position in response to two of the optical beams, substantially irrespective of the distance between the pylon and fuselage, and a radially variable detector which detects elevation and azimuth changes of the pylon with respect to the fuselage from a null position in response to the third of the optical beams, substantially irrespective of the distance between the pylon and fuselage.

Abstract: A soccer training device including a soccer ball located within a net. The net is attached to one end of a bungee cord and the other end of the bungee cord is attached to a strap which is placed about a person's wrist or ankle. The person kicks the ball within the net and by having the strap fastened to his limb the ball is propelled away from the person and then returned to his vicinity allowing the person to play soccer by himself.

Abstract: Methods and apparatus for monitoring and training eye position under clinical conditions are provided in accordance with the teachings of the present invention. An infrared optometer is employed to measure a patient's corneal and retinal reflection and outputs therefrom are employed to generate tone information and viewable patient information indicative of eye position and the state of focus. A patient is trained until a predetermined proficiency in the voluntary control of eye position is achieved.

Abstract: A portable television camera and recording device is provided for generating, monitoring, and recording still and motion picture information. The device is provided within a single housing permitting the housing to be pointed at an object or scene to be recorded. A television camera or flying spot scanner, a television recorder such as a magnetic tape video recorder, and a visual monitor such as a cathode ray tube are supported within the housing. Manually operable controls such as switches which may be selectively actuated to perform such functions as monitoring and/or recording are provided. The major components of the portable unit, such as the television camera, magnetic tape recorder, monitor and electronic control units, are preferably modular and capable of being removed and replaced without difficulty.

Abstract: Adjustable ring structure is provided in accordance with the teachings of the present invention wherein a ring shank is hinged to define first and second arcuate elements having an aperture therebetween. According to one preferred embodiment, a ring top having first and second slider members is disposed within the opening with the first and second slider members slideably mounted within interior groove portions in each of the first and second arcuate elements. First and second arms are provided for connecting the ring top to corresponding locations on the first and second arcuate elements adjacent to the opening to allow the ring top to be displaced to expand and contract the ring shank while an overall round configuration is maintained.

Abstract: An hollow sphere, in accordance with the preferred embodiment of the invention, has a slot formed on a somewhat less than semicircular portion of the great circle that separates the sphere into two hemispheres. A shower curtain grommet support is spaced inwardly of said slot to engage a shower curtain grommet and support a portion of the curtain. A pair of diametrically aligned small circles in the plane of hemispherical separation enables the holder to move freely on a shower curtain rod.

Abstract: Adjustable ring structure is provided in accordance with the teachings of the present invention wherein a ring shank is hinged to define first and second arcuate elements having an aperture therebetween. According to one preferred embodiment, a ring top having first and second slider members is disposed within the opening with the first and second slider members slideably mounted within interior groove portions in each of the first and second arcuate elements. First and second arms are provided for connecting the ring top to corresponding locations on the first and second arcuate elements adjacent to the opening to allow the ring top to be displaced to expand and contract the ring shank while an overall round configuration is maintained.

Abstract: Methods and apparatus for performing accommodation training under clinical conditions are provided in accordance with the teachings of the present invention. An infrared optometer is employed to measure a patient's accommodation and outputs therefrom are employed to generate tone information and viewable patient information indicative of the state of focus in a rapid manner. A patient is trained at an empirical rate determined by the viewable information until a predetermined proficiency in the voluntary control of accommodation is achieved. Thereafter, stimuli to accommodation, the accommodation convergence reflex and blur cue information are selectively introduced to generalize the voluntary control of accommodation achieved to a conventional environment so that the same may serve to reduce various visual acuity problems in a patient being trained.

Abstract: A circuit produces a control signal which is input through a bi-directional communication device to a removable circuit. The removable circuit is set to a first logic state which is a function of the control signal and thereafter steps through a sequence of logic states with each logic state being a function of the previous logic state. The entire sequence of logic states is represented by a state signal or code word which is a function of the control signal. The produced state signal is compared to a predetermined stored state signal. Access is enabled in response to the production of a proper sequence of logic states, as indicated by the comparison of the produced state signal to the predetermined stored state signal. Security is improved because without knowledge of the control signal input to the removable circuit, an unauthorized user cannot ascertain the code word.
