Abstract
The invention relates to a method and system for determining the topography for reaction signals of an eye. The reaction signals of cyclic luminous excitations are simultaneously measured on partial surfaces of the retina by using, for each partial surface, another integer number of oscillations in a predetermined time segment. These oscillations are derived from a clock rate. In the time segment, a smaller number of oscillations occur by prolonging a clock pulse by an appointed interval, and a greater number of oscillations occur by shortening the clock pulse by an appointed interval. The cumulative signal recorded on the patient contains the sum of the reaction signals and is digitized in an amplified and filtered manner with the clock pulse for generating the oscillations. The reaction signals of the individual partial surfaces are recovered by cyclic summation. This is effected by, for the corresponding partial surfaces, removing values at the prolonged locations or inserting the mean values of adjacent measuring points at the shortened locations.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
