The invention provides a real-time verification system for operators of aircraft, vehicles, and other modes of transportation for safety and security before commencing travel. The system comprises a processing device installed in the preferred mode of transportation, and includes a processor, memory, and an AI model. The processor integrates modules for receiving biometric data (fingerprint, facial, or retinal scans), verifying identities against a cloud database of operator data and the Terrorist Screening Database (TSDB), and communicating results to Air Traffic Control (ATC). The AI model performs advanced analytics, monitoring verification data against comprehensive databases, and predicting potential issues by analyzing historical trends. It generates detailed reports and alerts for ATC and other authorities, contributing to both immediate safety and long-term improvements. This system ensures that only authorized operators can control the vehicle while fostering ongoing safety enhancements through predictive analytics and trend identification.

A method for projecting image content onto the retina of a user using an optical system. Image data are captured using the image processing device. A first subset of the image data is blanked, thereby generating an active second subset of image data. The first and second subsets make up the total amount of the image data. The projector unit is controlled using the image data such that there is always only one eye box, generated on a common imaging path, with the same active image data arranged in the region of a first pupil region of the user. The first pupil region surrounds the pupil center. A portion of the eye box is arranged with a portion of the active image data within a second pupil region of the user. The second pupil region surrounds the pupil center. The second pupil region is arranged within the first pupil region.

A clinical decision support system for retinal diseases processes OCT retinal scan images to enhance certain aspects of speckle, which has been found to include relevant information that can be used to enhance the diagnosis and classification of the severity and progression of any disease found in the retina scan image. A copy of the original OCT retinal scan image is processed using a shifted window transformer block to enhance the relevant speckle information, and combine it with the original image, which is then evaluated by a trained system to classify the retinal features, including the speckle.

SOLUTION: A multi-instance light emission system for a retinal scanning near-eye display is disclosed. And at least one light direction modifier for modifying a light emission direction of the plurality of light emitting units such that optical paths of a first collimated light signal and a third collimated light signal from the plurality of collimated light signals emitted by the plurality of light emitting units have optical paths or optical path extensions that converge to form a first convergence point, and such that optical paths of a second collimated light signal and a fourth collimated light signal from the plurality of collimated light signals have optical paths or optical path extensions that converge to form a second convergence point.SELECTED DRAWING: Figure 4A
