  • Patent number: 8382286
    Abstract: A method of measuring retinal or visual pathway function comprises stimulating optokinetic nystagmus by presenting a visual stimulus to a patient; modifying a first parameter of the visual stimulus; modifying a second parameter of the visual stimulus; and using the modified visual stimulus to determine a threshold stimulus for optokinetic nystagmus; wherein the first and second parameters are selected from a group of parameters comprising a pattern for the visual stimulus, a width of the visual stimulus, a distance between the visual stimulus and the patient, a spatial frequency of the visual stimulus, a rate of change or temporal frequency of the test face of the visual stimulus, and a contrast between elements of the visual stimulus.

  • Patent number: 7396128
    Abstract: The visual function is determined with the help of test images, comprising inducing photostress induced by illuminating the eye with an intense light, then measuring the time needed for the recovery of the visual function before the illumination. The test images are periodically moving test images, and the visual function is determined on the basis of detecting the phenomenon of optokinetic nystagmus. According to another process the visual function is determined by measuring critical fusion frequency (CFF) before and after the photostress.

  • Patent number: 5199711
    Abstract: A three-dimensional logical toy having regular, irregular or amorphous composite members of various shapes as symbol-bearing components and forming a unit, whereby the shaped members making up the composite body may be allocated to three main groups within which the configurations are identical, and whereby the shaped bodies may be rearranged by rotation along the axis traversing the geometrical central point of the composite body. The composite enclosing body (1) is made up of 18 shaped members (2, 3, 4) falling into three different groups and arranged in three mutually parallel layers, which are delimited by two surfaces, viz. one having the configuration of a regular hexagram and one parallel thereto having the configuration of a regular hexagonal. The body is shaped as a composite, form-locked enclosing body along the surface of hexagram configuration.
