Abstract: Systems, methods, and/or computer-readable media described herein provide technical solutions to aid in the color matching of dental restorations. These systems, methods and/or computer readable media may receive a three-dimensional (3D) model of a tooth, where the 3D model includes a plurality of voxels, set each voxel to a starting optical property, and form a 3D visible light model from the 3D model by iteratively adjusting the optical property of each voxel based on optical properties measured from a scan of the tooth, where the 3D visible light model provides information to generate a color matched dental restoration.

Abstract: Methods and systems are described that mark and/or correct margin lines and/or other features of dental sites. In one example a three-dimensional model of a dental site is generated from intraoral scan data of the dental site, the three-dimensional model comprising a representation of a preparation tooth. An image of the preparation tooth is received or generated. Data from the image is processed using a trained machine learning model that has been trained to identify margin lines of preparation teeth, wherein the trained machine learning model outputs a probability map comprising, for each pixel in the image, a probability that the pixel depicts a margin line. The three-dimensional model of the dental site is then updated by marking the margin line on the representation of the preparation tooth based on the probability map.

Abstract: Systems and methods for a radar-based viral transmission prevention for a protected space are disclosed. The system comprises a gateway screening system 104 configured for remotely screening subjects crossing a boundary of a protected space, an elevator monitoring system 106 configured for monitoring passengers using an elevator system and a social distance monitoring system 108 configured for monitoring social distancing compliance within the protected space. The system also includes a telemedical monitoring system 110 configured and operable for remotely measuring one or more parameters of a patient using a radar-based system. The system further includes a gesture recognition system 112 configured and operable to identify hand gestures remotely.

Abstract: Methods and apparatuses for generating and displaying a model of a subject's teeth. Described herein are intraoral scanning methods and apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth). These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth.

Abstract: A method includes receiving intraoral scan data of an intraoral cavity of a patient; processing the intraoral scan data to determine, for each dental condition of a plurality of dental conditions, whether the dental condition is detected for the patient and a severity of the dental condition; and presenting indications of the plurality of dental conditions together in a graphical user interface (GUI), wherein the indications show, for each dental condition of the plurality of dental conditions, whether the dental condition was detected for the patient and the severity of the dental condition.

Abstract: Calibrating an intraoral scanner includes obtaining reference data of a reference three-dimensional (3D) representation of a calibration object and obtaining, based on the intraoral scanner being used by a user to scan the 3D calibration object, and from one or more device to real-world coordinate transformations of two-dimensional (2D) images of the 3D calibration object, measurement data. Calibrating the intraoral scanner further includes aligning the measurement data to the reference data to obtain alignment data and updating, based on the alignment data, said one or more transformations.

Abstract: Intraoral scanning systems for displaying 3D models of a patient's dental arch and near-IR images from the dental arch. These systems may include a wand with one or more image sensors and processors for processing the 3D models and near-IR information. The 3D models may include surface (e.g., color) information and the near-IR images may include information on internal structures, including enamel and dentin.

Abstract: A processing device is interfaced with an auditory region of the brain of a subject that is responsible for auditory perception. The processing device receives signals associated with nerve impulses that are transmitted to the auditory region of the brain of the subject in response to sound collected by an ear of the subject. The processing device processes the received signals and generates at least one audio signal that is representative of the auditory perception, by the subject, of the sound collected by the ear. In certain embodiments, the processing device processes at least one audio signal that is representative of at least one sound to convert the at least one audio signal to a sequence of nerve impulses, and selectively provides the sequence of nerve impulses to the auditory region of the brain of the subject such that the subject audially perceives the at least one sound.

Abstract: A processing device receives signals associated with nerve impulses that are transmitted to the visual cortex of a subject in response to one or more visual stimuli provided to at least one eye of the subject. The processing device processes the received signals and generates digital image data from the processed received signals that is representative of the visual perception, by the subject, of the one or more visual stimuli. In certain embodiments, the processing device processes digital image data that is representative of a scene to convert the digital image data to a sequence of nerve impulses, and provides the sequence of nerve impulses to the visual cortex of a subject such that the subject visually perceives the scene.

Abstract: A plural chambered container for storing separately a plurality of substances for mixing prior to opening the container. The container comprises a closed outer container having a side wall, bottom and top. It further comprises an inner chamber with a designated opening area, wherein the inner chamber is operatively attached to the bottom of the outer container. In addition the outer container is filled with a first substance and the inner chamber is filled with a second substance. The outer container is filled with a one substance and the inner chamber is filled with another substance. Upon pressing the side walls of said outer container, the designated opening area is opened thereby causing the substance in the inner chamber to mix with the substance in the outer container.
