An automated system and method, capable of detecting, analyzing and summarizing a person's eye movements is used to detect (diagnose) (either before or after symptoms of said neurological disease are apparent), confirm a prior diagnosis, and/or to monitor the treatment effectiveness for a variety of neurological diseases, neurological movement disorders and potential brain injuries. The analyzed and summarized eye movements are cataloged, interpreted and utilized in a diagnostic matrix in order to highlight and distinguish abnormal eye movements, and to provide an objective clinical or pre-clinical/pre-symptomatic diagnosis based on the non-invasive testing procedures. | 01-28-2016 |

20160073945 | METHODS AND SYSTEMS FOR RAPID SCREENING OF MILD TRAUMATIC BRAIN INJURY - The disclosure provides for easy, reliable, and rapid screening of a mild traumatic brain injury (mTBI) based on a modeling of a subject's tracking of a dynamic target during the course of a simple motor tracking task. The gathered tracking data can be used to calculate tracking errors between the subject's actual input (e.g., grip force) and the intended target input. The tracking errors may be used to generate numerical values for model parameters that correlate the subject's responses to the tracking errors during the course of the dynamic motor tracking task. A classification model may be used to compare the model values to multi-subject model values of known diagnoses for mTBI. The entire screening process can be effectively administered in a matter of minutes or less, and with a high degree of accuracy. | 03-17-2016 |

20160089018 | A METHOD FOR MEASURING VISUAL ACUITY - The invention is a system and method for measuring visual acuity. The system comprises a computer or projector adapted to project a computer generated image of an optotype on a surface, e.g. a computer display screen or a screen on a wall, and a control unit. The computer or projector is adapted to project the optotypes with a steadily changing size as a continuum of images. The testing is carried out by changing the optotype size in both directions in order to compensate for the reaction time of the patient. For example, starting with a large optotype, the size is steadily decreased until the patient signals that he can no longer read the optotype. The test then continues starting from a small optotype and steadily increasing the size until the patient signals that he can read the optotype. | 03-31-2016 |
