OVEREXTENSION HINGE SYSTEMS FOR GLASSES DEVICES

Systems, methods, and devices, and computer program products are provided for hinge modules for smart glasses systems, and overextension hinge modules usable with one or more electronic components. In an example, an overextension hinge module may include a hinge base, a paddle connected to the hinge base via a travel pin, and a preloaded spring maintaining a base position between the hinge base and the paddle, allowing movement of the hinge base relative to the paddle along a predefined range. Various examples may include a primary pivot axis defining movement between a frame arm attached to a glasses frame, and an external pivot axis along an outer edge of the frame arm defining an over-extension of the pivot arm relative to the frame

Direct View Rendering with Head Tracking Feedback for 3D Video Calling

When participants engage in a video call, discrepancies between the viewing direction from which a participant views other participants and the displayed view of the other participants can lead to a less than satisfactory experience. This disclosure describes techniques to select a subset of available cameras based on head and/or eye movements of participants in a video call to render a corresponding direct view. Cameras capture images of a viewing user that is viewing a display on which a 3D video of a second user (e.g., generated from images captured by a subset of a plurality of cameras) is displayed. Per techniques of this disclosure, with user permission, the head and/or eye movements of the viewing user are tracked based on the captured images of the viewing user. Relationship between the tracked movements of the viewing user and a view of the display of the device is determined. The view of the first display is then updated to render a 3D video based on a subset of individual cameras of a second user’s device that match the movement (which corresponds to an updated viewing position) of the viewing user. The view on the first display is updated to show the second user from a corresponding perspective. The techniques can provide a more accurate experience during a three-dimensional (3D) video conference. Suitable techniques such as machine learning can be utilized to predict the user’s movement and adjust the view accordingly

Electronic Barrier And Enforcement System And Method

Disclosed are systems and methods for implementing an electronic tollway barrier system. Exemplary systems and methods use positive vehicle identification at progressive monitoring locations to determine whether a vehicle has illegally entered a controlled lane across the electronic barrier, ensure that toll locations are not circumvented, and automatically issue citations to violators of the electronic barrier.State Road And Tollway AuthorityGeorgia Tech Research Corporatio

Forward-imaging optical coherence tomography (OCT) systems and probes

Provided are forward-imaging optical coherence tomography (OCT) systems and probes. In one embodiment, a scanning reflector surface is configured to be rotated about two axes in a single operating plane to direct light transmitted along the sample path to a sample to be imaged.Board of Regents, University of Texas Syste

MULTIPLEXED OPTICAL COHERENCE TOMOGRAPHY (OCT) IMAGING SYSTEM

Implementations of systems and methods of multiplexed OCT systems are disclosed herein. The field of view (FOV) and/or the wavelength of multiple OCT systems may be multiplexed. In contexts where the human eye will be imaged, power safety limits constrain the signal-to-noise (SNR) and/or speed of the OCT imaging. For retinal imaging, near-infrared wavelengths of 800 nm - 1100 nm may be used. For non-retinal imaging, 1200 nm – 1800 nm may be more typical. In implementations of the disclosure, a wavelength and FOV multiplexed OCT system generates whole eye biometry. The whole eye biometry may be at a first wavelength (e.g. approximately 1060 nm) and a face-biometry may be at a second wavelength (e.g. approximately 1300 nm). The eye biometry systems may include eye or pupil tracking sub-systems and pupil steering elements. One or both eye biometry systems may be moveable to allow for different inter-pupillary distances
