Abstract: An automated method for generating a final setup for orthodontic treatment. The method includes receiving a digital 3D model of teeth in an initial state. The method computes a scoring function based upon metrics related to the initial state to generate a corresponding score, perturbs the state of the teeth through translations and rotations of a tooth or set of teeth to generate a perturbed state of the teeth, and updates the state of the teeth based upon the score and the perturbed state of the teeth to generate one or more final setups representing a final state of the teeth after the orthodontic treatment.

Abstract: A product authentication system includes one or more image capture devices that provide video data representative of an enhanced safety environment. The product authentication system can determine the continuous presence of a designated product during a time period, for example, during performance of a task in an enhanced safety environment. The video data can be spatiotemporally sliced according to multiple orientations with respect to the time axis and the two spatial axes. A plurality of data streams are created where the slices of each respective data stream have the same orientation. The data streams are processed according to one or more machine learning models, such as convolutional neural networks trained to determine whether the designated product is continuously present in the video data. An indicator of the continuous presence of the designated product can be provided to a downstream system and used to indicate whether functions of the downstream system are to be performed.

Abstract: Systems and methods for sensing and alerting nearby workers to the presence of objects within areas there they are prohibited. The objects have smart tags associated with them, and transceivers monitor an exclusion zone for the entry of objects into the exclusion zone. An alert system provides notification of the detection of the entry of such an object into the exclusion zone.

Abstract: A fit detection system for a respiratory protection device is presented. The system includes a camera that captures an image sequence of a user wearing the respiratory protection device. The system also includes a feature extractor that analyzes the image sequence and extracts features from the image sequence. The system also includes a fit score calculator that analyzes the extracted features and calculates a fit score indicative of how well the respiratory protection device fits the user. The system also includes a communication component that communicates the fit score.

IPC: G06N20/00
Abstract: The present invention relates to a computer-implemented method of generating a final setup for orthodontic treatment using supervised machine learning for direct mapping, comprising receiving, by one or more computer processors, a training set of patient case data which includes malocclusion states and ground truth images representing final setup states for the teeth of one or more patients, wherein the final setup states represent orthodontic post-treatment positions of a person's teeth and the malocclusion states are pre-treatment positions of the teeth and are represented by digital 3D models of teeth in an initial state, generating, by the one or more computer processors using a deep neural network, a generated output image, computing, by the one or more computer processors, a distance between a generated output image and the ground truth image representing the final state using a loss function, and minimizing, by the one or more computer processors, the distance to train, at least in part, the deep neural network.
