  • System and method for testing retinal function
    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.
    Type: Grant

  • Process and apparatus for examining the visual functions of the eye
    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.

  • Mobile telephone and method for its manufacture
    Patent number: 7010121
    Abstract: A mobile telephone having a single piece molded housing or shell includes a core assembly for supporting the functional components of the mobile telephone. The core assembly may further include ancillary hardware components such as an electrical power source, user interface input/output devices, and the like required for operation of the telephone. The single piece molded shell molded about the core assembly so that the core assembly is substantially enclosed by the shell.
