  • Systems and methods for graphical symmetry breaking
    Patent number: 12287783
    Abstract: A system and method include breaking symmetry in a query graph by converting the query graph into a transformed query graph by generating a symmetry breaking expression that includes detecting one or more orbits in the transformed query graph, selecting an orbit from the one or more orbits having more than one node, generating an automorphism breaking sub-expression for the selected orbit, assigning a node of the selected orbit a unique node attribute, recalculating the one or more orbits in the transformed query graph, repeating the process until each node is in its own orbit, and combining each of the automorphism breaking sub-expressions to obtain the symmetry breaking expression. Using the symmetry breaking expression, the system and method include finding one or more subgraphs of a main graph that match the symmetry breaking expression of the query graph.

  • Techniques for integrated preheating and coating of powder material in additive fabrication and related systems and methods
    Patent number: 12285914
    Abstract: Techniques for improved efficiency of sintering in additive fabrication are described. According to some aspects, mechanisms for depositing and leveling source material are combined with a mechanism for heating the material. In some embodiments, one or more heating elements may be arranged to lead and/or follow a material deposition mechanism such that heat may be applied to the build region in concert with deposition of material. As a result of this technique, the heating and depositing steps may be performed closer together in time and/or heat may be applied more directly to the material than in conventional systems. As a result, greater control over material temperature may be achieved, thereby avoiding excess temperature exposure and subsequent undesirable changes to the material.

  • Natural language dialog system for computer program interaction
    Patent number: 12285688
    Abstract: A video game system provides dialog responses based on a natural language model (NLM). The NLM is a language model that receives a language input, such as a dialog selection, audio recording, or natural language text input provided by a user of the video game system. In response to the language input, and based on a corpus of natural language candidate lines, the NLM identifies one or more potential responses. The video game system selects a final response from the identified potential responses and provides the selected response to the user via, for example, one or more display frames or via an audio output.
