Abstract: The OculoKinetic Device is used to test an individual to evaluate brain function including, but not limited to, identifying the presence of a traumatic brain injury or central nervous system disease which manifests itself through abnormal ocular responses to stimuli by using the high-speed tracking of an individual's eye movements (monocular or binocular, and either conjugate or disconjugate in horizontal, vertical, or torsional directions or combinations thereof), pupil size and reactivity, eyelid position, and blink parameters, and optionally along with other ocular elements, i.e., eyeball pressure, temperature, blood flow, etc. The eye movement stimulus protocol uses a target that moves in any direction of a two- or three-dimensional plane and may use a color display or geometric shapes. In addition, the stimuli can be used in conjunction with cognitive testing, balance assessment, and other non-eye tests.

Abstract: The present system for analyzing eye responses accurately and automatically tracks the size, location, and movement of a subject's pupil(s) in response to a predetermined test protocol. These eye responses include both ocularmotor and pupillary responses to illumination and target tracking for either eye or both eyes simultaneously. The series of digital image frames of a subject's eyes, taken during the execution of a predetermined stimulus protocol, are automatically processed to determine pupil location, size, and responsiveness to changes in illumination.

Abstract: The impairment determination system automatically determines impairment of a subject based on pupil movement, as well as pupil responses to illumination and target tracking for either eye or both eyes simultaneously. The impairment determination system automatically processes a series of digital image frames, taken during the execution of a predetermined test protocol, to determine pupil location, size, and responsiveness to changes in illumination, which data are used by the impairment determination system to determine impairment of the subject. The present impairment determination system uses a method for quickly and accurately localizing the subject's pupils, as well as their boundaries, area, and center coordinates, which data is used as part of the impairment determination process.

Abstract: The present system for analyzing eye responses to automatically detect deception obtains a series of digital image frames from a headset. This system precisely controls the illumination generated by the headset to bias the subject's pupils and automatically and precisely determine the subject's pupil location, size, and responsiveness. These measurements enable the system for analyzing eye responses to automatically detect deception by accurately measuring the subject's involuntary pupillary responses to questions posed by an examiner. These measurements can be used exclusively or in combination with one or more of the standard elements of the polygraph machine to automatically detect deception.

Abstract: The image-based system is used to observe and document eye responses which can be used to implement the procedures defined in the Standardized Field Sobriety Test as well as the Drug Recognition Expert Program. These eye responses include pupil movement as well as pupil size and responses, for either one or both eyes simultaneously. The system includes a headset against which the subject places their face. The faceplate has two eye openings through which illumination devices transmit beams of infrared light to illuminate the subject's eyes. Two imaging devices are mounted on the headset opposite the eye openings to generate images of the subject's illuminated eyes. The generated images are transmitted to an image recording device for storage and an image display device for display to a test administrator.

Abstract: A non-invasive apparatus for monitoring physiological responses for detecting the presence of drug impairment. The oculomotor and pupillary system is monitored and evaluated to detect the ingestion of drugs and the impairing effect or influence thereof. The horizontal, vertical, oblique and torsional eye movement, eye lid blink activity as well as the size and reactivity of the pupil are the primary data sources. An enclosed chamber surrounds each of the eyes of the subject, and thereby precludes the admission of ambient light. Within each chamber are disposed point sources of infrared radiation specifically oriented with respect to the subject's eye. An infrared sensitive video camera is positioned to minimize the effect of cosine compression within each chamber relative to the subject and is positioned with respect to the infrared radiation sources in order to provide maximum contrast between the pupil and iris of the eye.

Abstract: A system for viewing and recording eye movement. Enclosed spherical eye pieces form goggles which are adapted to cover each of the eyes of the user to preclude the admission of ambient light. An infrared radiation source impinges upon the user's eye, the radiating energy being in the non-visible portion of the energy spectrum. The interior surface of each eye piece is coated with a surface adapted to reflect and disperse the radiating infrared energy. An infrared sensitive video camera is directly coupled to the goggle eye pieces, the camera being sensitive to infrared radiation. The output of the video camera is connected to monitoring apparatus for monitoring and recording the real-time observation of the user's eye movements.
