Patents by Inventor Peter Derr

Peter Derr has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9367915
    Abstract: A method of analyzing an OCT image. An OCT image has many differently colored dots. The system detects the number of differently colored dots, quantifies them and performs statistical analyses to determine a likelihood of disease. The different colored dots correspond to different retina cell types and structures.
    Type: Grant
    Filed: July 22, 2014
    Date of Patent: June 14, 2016
    Assignee: Diopsys, Inc.
    Inventors: Peter Derr, Alberto Gonzalez, Laurie Cox

  • Patent number: 7578795
    Abstract: A system and method for performing a vision examination includes displaying a series of visual stimuli for observation by a patient and detecting the patient's visual evoked potentials in response to the visual stimuli. Electrical signals representative of the visual evoked potentials for each stimulus of each series of visual stimuli displayed is amplified, converted to digitized data, recorded and measured. The measured visual evoked potential data is then evaluated and compared to certain predetermined values in order to detect whether or not the measured data is reliable. Data outside of predetermined ranges of values is considered faulty data. For example, the measured data is compared to a maximum value of the output of an amplifier used to enhance the electrical signals, to a predetermined value of the Fourier component at 60 Hz; and to certain ranges to determine if the measured data are outside of expected limits. The occurrence of such data outside these ranges is faulty data.
