  • Patent number: 11903720
    Abstract: A system and method of detecting eye movements of a subject for the diagnosis of neurological disorders. The method includes tracking eye movements of the subject, identifying microsaccades from the tracked eye movements, and characterizing microsaccade dynamics of the identified microsaccades to determine one or more parameters, such as microsaccade direction, microsaccade velocity, microsaccade magnitude, microsaccadic peak velocity-magnitude relationship, microsaccade duration, and intersaccadic intervals. The method also includes comparing the one or more determined parameters with a corresponding control parameter, assessing the comparison to determine differences between the one or more determined parameters and the corresponding control parameters, and generating a report including the diagnosis of neurological disorder based on the assessment.

  • Publication number: 20230389840
    Abstract: Systems and methods for detecting deceptive intent of a subject include observing eye movements of the subject and correlating the observed movements to known baseline neurophysiological indicators of deception. A detection system may record eye movement data from the subject, compare the eye movement data to a data model comprising threshold eye movement data samples, and from the comparison make a determination whether or not the subject is lying. The detection system may create an alert if deception is detected. The eye movements detected include saccadic and intersaccadic parameters such as intersaccadic drift velocity. Measurements may be collected in situ with a field testing device, such as a non-invasive, non-contact device attached to the subject's computing device and configured to non-obtrusively record the eye movement data.

  • Publication number: 20230329547
    Abstract: Systems and methods for detecting a traumatic brain injury (TBI). The system comprises a sensing arrangement and a control unit. The sensing arrangement collects eye movement data of a user. The control unit is in communication with the sensing arrangement and configured to compare the eye movement data to one or more baseline measurements of eye movement dynamics. The control unit is also configured to generate an alert indicating the presence or severity of the TBI for delivery to control unit administrator if the eye movement data diverges from one or more of the baseline measurements by a threshold amount.

  • Publication number: 20230200641
    Abstract: A system and method for determining a subject's attentional response to a stimulus. The method includes measuring microsaccadic eye movement dynamics of the subject, detecting whether a microsaccadic signature (a suppression in microsaccadic rate) is present in the measured microsaccadic eye movement relative to a time of the stimulus, and correlating the subject's attentional response to the stimulus based on the detection. The method further includes determining that the stimulus was sensed if the microsaccadic signature is present and determining that the stimulus was not sensed if the microsaccadic signature is absent.

  • Publication number: 20230009372
    Abstract: Systems and methods for detecting onset, presence, and progression of particular states, including intoxication, include observing eye movements of a subject and correlating the observed movements to known baseline neurophysiological indicators of intoxication. A detection system may record eye movement data from a user, compare the eye movement data to a data model comprising threshold eye movement data samples, and from the comparison make a determination whether or not intoxication or impairment is present. The detection system may alert the user to take corrective action if onset or presence of a dangerous condition is detected. The eye movements detected include saccadic and intersaccadic parameters such as intersaccadic drift velocity. Measurements may be collected in situ with a field testing device. An interactive application may be provided on a user device to provoke the desired eye movements during recording.

  • Patent number: 11123444
    Abstract: The present disclosure is directed to methods and a diagnostic kit for producing pericyte information from a subject for identifying and/or treating a subject condition. In one aspect, a method for identifying a subject condition is provided. The method includes administering intravenously to a subject an effective amount of a solution comprising fluorescent markers to selectively label a plurality of pericytes in the subject's body. The method also includes acquiring fluorescence signals originating from labeled pericytes to produce pericyte information associated with tissues of the subject's body. The method further includes generating a report identifying a subject condition using the pericyte information. In some aspects, a treatment may be adapted using the identified subject condition.

  • Patent number: 10292584
    Abstract: Systems and methods for detecting onset, presence, and progression of particular states, including hypoxia, include observing eye movements of a subject to and correlating the observed movements to known baseline or hypoxic conditions. A detection system may record eye movement data from a user, compare the eye movement data to a data model comprising threshold eye movement data samples, and from the comparison make a determination whether or not hypoxia, fatigue, or other detrimental conditions are present. The detection system may alert the user to take corrective action if onset or presence of a dangerous condition is detected. The eye movements detected include saccadic and intersaccadic parameters such as intersaccadic drift velocity. Measurements may be collected in situ while the subject is performing normal duties, processed to determine indicators of detrimental conditions, and reported to the subject within a few seconds.
