  • Publication number: 20180192868
    Abstract: An ophthalmic examination system of an exemplary embodiment includes a plurality of ophthalmic examination apparatuses, a plurality of examiner terminals, a communication establishing device, an information transmitting device, and an output device. The communication establishing device is capable of establishing communication between at least three apparatuses including at least one of the plurality of ophthalmic examination apparatuses and at least two of the plurality of examiner terminals. The information transmitting device transmits at least part of information transmitted from one of the at least three apparatuses between which the communication has been established by the communication establishing device, to at least one of other two or more apparatuses. The output device outputs information transmitted by the information transmitting device.

  • Patent number: 7597445
    Abstract: The present invention is directed to a program for optometry, which is used for a control device. The program includes a first unit to measure an amount of heterophoria of eyes of an examinee to be examined in a horizontal heterophoria examination, a second unit to display an operating method to allow the examinee to implement a Sheard criterion identifying examination on a display device, a third unit to allow the examinee to implement a convergent or divergent test of the eyes based on the operating method, and a fourth unit to calculate a prism amount for prescriptions based on the heterophoria amount and the convergence or divergence of the eyes.

  • Patent number: 5682831
    Abstract: A water surface glide sailboat utilizing wind power propelling is disclosed wherein the sailboat includes a flat bottom float mounted on a beam at a joint having an axis parallel to the keel line of the sailboat so that the floats are further capable of rolling about the axis. The sailboat can be further equipped with a steering gear including a controlling stick connected to the joint so that the sailboat crew can control a flat bottom float and restrain the fluctuation of the flat bottom float to keep the parallel condition against water surface regardless of the heel of the boat and thereby decreasing the water resistances.
