Abstract: A method for removing artifacts from an electroretinogram, the method comprising: visually stimulating at least one eye of a test subject, and using at least two electrodes to measure electrical responses from the at least one eye of the test subject; recording the electrical responses during, and for a predetermined period of time after, the time at which a visual stimulation is applied, whereby to generate a data set, wherein each electrical response is represented as a sweep comprising a plurality of voltage amplitude values and a plurality of corresponding time values; applying an elevated high pass filter to each sweep, wherein the elevated high pass filter is configured to remove any signal components with a frequency value of <1 hz; and plotting the resulting data set as an electroretinogram, in which the plurality of voltage amplitude values of the remaining signal is plotted on a first axis of an electroretinogram, and the plurality of corresponding time values of the remaining signal is plotted o

Abstract: Apparatus for the assessment of electrophysiological signals obtained from a patient, the apparatus comprising: a housing; a support arch pivotally mounted to the housing, the support arch comprising a plurality of facial contact point supports for supporting contact points on the face of the patient relative to the support arch without supporting the chin of the patient; at least one display screen for presenting a stimulus to a single eye of the patient, the at least one display screen being movable relative to the support arch; and control electronics disposed within the housing for driving the at least one display screen and for amplifying electrophysiological signals obtained from the patient.

Abstract: Apparatus for ophthalmic electrophysiological testing, the apparatus comprising: an EER stimulator for providing an electrical stimulus to an eye so as to evoke an electrophysiological response, wherein the EER stimulator comprises a power source; an amplifier for receiving the electrophysiological response and measuring that response, wherein the amplifier is integrated with the EER stimulator; and at least one switch disposed between the power source and the amplifier for isolating the power source from the amplifier when the electrical stimulus is delivered to the eye.

Abstract: A method for standardizing diagnosis of medical conditions. The method includes defining first order data to collect for a patient having at least one symptom and providing a computing system for assigning a diagnosis of a medical condition from possible diagnoses corresponding to possible medical conditions. The computing system includes a memory system storing analysis modules that include tissue-pathology characteristics databases for the possible medical conditions corresponding to the possible diagnoses. The method includes receiving in the memory system the first order data for the patient, comparing with the computing system the first order data to the tissue-pathology characteristics databases, and assigning fit scores for each of the possible diagnoses based on the comparison between the first order data and the tissue-pathology characteristics databases. The method includes assigning the diagnosis of the medical condition for the patient based on the fit scores.

Abstract: Described is a method and system that facilitates triage of thousands to millions of potential patients within a relatively short period of time by scanning of a substrate of a designated card issued to a victim. The method and the system comprise a plurality of noninvasive self-testing test devices located at a plurality of remote peripheral self-testing sites, and each one of the plurality of noninvasive self-testing test devices facilitates self-testing of the substrate of the designated card. Each of the plurality of noninvasive self-testing test devices provides test results of the scan of the substrate of the designated card, and the potential patients are identified, then subsequently screened and triaged based upon the test results of the scan of the substrate of the designated card.
