  • Patent number: 12008568
    Abstract: An example method includes receiving an encrypted biometric enrollment data and user identifier data. The encrypted biometric enrollment data includes at least one biometric enrollment sample from a user encrypted using an encryption key. The encryption key is generated based on a user secret and the user identifier is associated with the user. The user identifier is matched with a stored user secret. A decryption key is generated based on the stored user secret. The encrypted biometric enrollment data is decrypted using the decryption key. The at least one biometric enrollment sample is retrieved from the decrypted biometric enrollment data. The at least one biometric enrollment sample is processed using a biometric processing algorithm to generate a biometric reference template. A biometric reference template identifier uniquely identifying the biometric reference template is generated. An encryption key is generated based on the stored user secret and encrypts an enrollment confirmation message.

  • Publication number: 20240177397
    Abstract: Methods and systems are described that use a three-dimensional (3D) model of a dental site to generate a panoramic two-dimensional (2D) image of the dental site. In one example, a method includes receiving a 3D model of the dental site generated at least in part from an intraoral scan, generating a surface shaped to substantially surround a dental arch represented by the dental site, computing a surface projection by projecting the dental site onto the surface, and generating the panoramic 2D image from the surface projection.

  • Patent number: 11979471
    Abstract: A push gateway brokers messages between backend services and client devices connected to the gateway. The gateway includes a plurality of messaging frontend servers, a messaging database, and a plurality of topic servers. The messaging frontend servers manage the socket connections connecting the client devices to the push gateway. The messaging frontend servers may further monitor the socket connections, collecting analytical data on the client devices and the connections. The messaging database is a key-value database that subscribes messaging frontend servers to topics. The topic servers receive publish requests from the backend servers to identify subscribed messaging frontend servers in the messaging database to push messages out to. The frontend messaging servers subsequently push out the message to the client devices subscribed to the topic.

  • Publication number: 20240075391
    Abstract: A location-based game helps players interact with their environment without interrupting the game. For example, while a player is playing the location-based game on a client device, the client device displays a virtual content item adjacent to a location (or building) associated with the content item. The content item may provide information about the location. The content item may be displayed without obscuring virtual objects of the game, thus allowing the player to continue playing the game and simultaneously learn about and interact with their environment.

  • Publication number: 20240065807
    Abstract: The present disclosure is directed to capturing a 3-dimensional representation of a patient's face from multiple angles to be integrated with (fused) with at least a 3-dimensional intra-oral mesh of the patient's teeth for purposes of visualizing a dental treatment plan. In one aspect, a method includes capturing media of a patient's face from multiple angles, using at least one device; transforming the media into a 3-dimensional representation of the patient's face; and transmitting, the 3-dimensional representation of the patient's face to one or more processing components to be integrated with a 3-dimensional representation of the patient's intra-oral scan to visualize a dental treatment plan for the patient.

  • Publication number: 20240033057
    Abstract: A method may include obtaining a first 3D model of an upper jaw of a patient using an intraoral scanner and obtaining a second 3D model of the lower jaw of the patient using the intraoral scanner. The method may also include capturing a series of 2D images of the upper and lower jaws of the patient as the patient is moves the upper jaw and lower jaw in dynamic occlusion and processing the captured series of 2D images to identify features associated with the upper jaw of the patient and the lower jaw of the patient. For each 2D image in the captured series of 2D images, the method may include identifying a relative position of the first 3D model and the second 3D model based on alignment of features in the first 3D model and second 3D model with the features identified in the 2D image to generate a series of relative positions of the first 3D model and the second 3D model.

  • Patent number: 11856214
    Abstract: One or more computing devices, systems, and/or methods for video encoding are provided. For example, a video file may be segmented into at least a first portion and a second portion. The first portion may be analyzed to determine that the first portion is associated with a first level of complexity, and the second portion may be analyzed to determine that the second portion is associated with a second level of complexity. A first bitrate associated with the first level of complexity may be determined, and a second bitrate associated with the second level of complexity may be determined. The first portion may be encoded at the first bitrate to generate a first encoded portion, and the second portion may be encoded at the second bitrate to generate a second encoded portion. The first encoded portion and the second encoded portion may be assembled to generate an optimized video file.
