Abstract: The use of ophthermometers in a new field of ophthermology in the passive detection of thermal discrepance in the eyes of a person and its relation to health impairment and/or alcohol and drug abuse. Ophthermology has many uses. It can be used to initially establish a baseline or normal temperature for reference in identifying future eye problems. Readings can be taken from the pupil iris area or the white of the eye from the optic nerve to the cornea. Taking eye temperature before eye surgery can determine whether blood flow is adequate to permit surgery. Eye surgery can be monitored to determine the extent surgical wounds have healed and when the cease medication. Eye temperature readings can determine the fit of contact lenses, especially in fitting abnormal distorted corneas. Eye socket temperature can be measured to detect infection after traume of eye removal. Eye temperature differential can indicate reduced carotid flow and early detection of risk of stroke.

Abstract: A rotatable detector for continuously monitoring twelve blood samples being evaluated by an instrument is disclosed. Each sample is held in a separate cuvette forming part of a cuvette tray. A single bulb illuminates all twelve cuvettes and the light passing through each cuvette is carried to a separate detector for that cuvette by a respective one of twelve light pipes. The cuvette tray receptacle bulb and twelve detectors all rotate as a unit to permit reagent dispensing at a single station while continuously monitoring the light transmission of each sample.

Abstract: An ophthalmic refracting chart projector having rotary slide discs, the images on which are projected on a screen, having remote operating controls permitting selective showing of the slides in selectable sequence.
