Abstract: The present disclosure relates to a dental scanning system for acquiring scan data of a physical three-dimensional dental object during a scanning session. The dental scanning system includes a scanning device and a first processing device for generating a 3D model. The dental scanning system may further include one or more second processing devices for rendering and/or displaying the 3D model. The dental scanning system is preferably suitable for continuously acquiring, processing, and transmitting images such that a video is streamed during the scanning session.

Abstract: Examples of the present disclosure describe systems and methods for ontology-based graph query optimization. In an example, ontology data relating to a graph or isolated collection may be collected. The ontology data may comprise uniqueness and topology information and may be used to reformulate a query in order to yield a query that is more performant than the original query when retrieving target information from a graph. In an example, reformulating a query may comprise reordering one or more parameters of the query relating to resources, relationships, and/or properties based on uniqueness information. In another example, the query may be reformulated by modifying the resource type to which the query is anchored based on the topology information. The reformulated query may then be executed to identify target information in the isolated collection, thereby identifying the same target information as the original query, but in a manner that is more performant.

Abstract: Controlling access to nodes in a relational graph at query time by using an approximate membership query (AMQ) filter and ordered queries based on historic grants or denials of access according to security context enables a more efficient querying of the relational graph while preserving access controls. Security contexts that grant or deny access to a node are stored in an associated AMQ filter and are queried according to the subject's security context in an order based on the frequency at which the security contexts have previously granted or denied access to nodes in the relational graph.

Abstract: Embodiments are directed to a packet capture ring that provides a single network tap for packet capture and a series of processors (or appliances) for handling serialization and search request processing in a confederated and highly scalable manner. One such appliance (a “primary” appliance) maintains a tap port to the network. Each packet capture appliance has a locally attached repository that stores raw packets and a juxtaposed index that allows for retrieval of those packets. The primary appliance sends a single copy of encapsulated packets in opposite directions around the ring to its descendants. A designation is made across the system as to a “currently designated” appliance for servicing requests for indexing and storage of captured packets. This current designation shifts from appliance to appliance in the system, as a “previously designated” appliance has its storage capacity filled.
