    摘要: An ocular system for detecting ocular abnormalities and conditions creates photorefractive digital images of a patient's retinal reflex. The system includes a computer control system, a two-dimensional array of infrared irradiation sources and a digital infrared image sensor. The amount of light provided by the array of irradiation sources is adjusted by the computer so that ocular signals from the image sensor are within a targeted range. Enhanced, adaptive, photorefraction is used to observe and measure the optical effects of Keratoconus. Multiple near-infrared (NIR) sources are preferably used with the photorefractive configuration to quantitatively characterize the aberrations of the eye. The infrared light is invisible to a patient and makes the procedure more comfortable than current ocular examinations.

    摘要: A digital eye data bank contains digital eye information concerning a plurality of different eyes in the form of schematic eve models. Each model contains a quantitative and qualitative description of the optical performance of a human eye that can be used to simulate the eye's optical performance. Each schematic eye model is associated with at least one of an age, race, gender, geographic residence, or medical diagnosis of a group of individuals. The digital eye data bank also contains personal information such as body height, weight, education background, and physical, chemical, and mental status that may correspond to an eye condition associated with the eye model. The digital eye data bank is used to evaluate the performance of ocular instruments through computer simulation and predict a measurement outcome among a population of subjects.

    摘要: The invention discloses a wool raw wool washing device for chemical fiber production, which includes a washing machine. The washing machine is provided with a working cavity. A front end wall of the working cavity is provided with a storage cavity with an upward opening. The wool raw wool is installed in the washing machine. Two dispersing mechanisms are symmetrically arranged in the working cavity in the storage cavity, and the dispersing mechanism includes a connecting shaft rotatably connected to the rear wall of the working cavity. A rotating wheel is fixed at the front end of the connecting shaft. The connecting shaft is provided with a collar that can slide back and forth, and the rotating wheel is provided with a slidable dispersing rod. The rotation of the connecting shaft can drive the rotating wheel to rotate, and the device can disperse the raw wool in the lump. After washing into small balls, it has a high washing efficiency, and by dispersing into small balls, it helps to discharge the stones and branches in the wool, and has a good washing effect. The overall mechanical linkage of the device is relatively good, High, more energy efficient.
