Abstract: In a search and database system, a graph generator builds a graph, comprising nodes and edges, and stores that graph in a database or other data structure and uses a repeated extending and culling process to build the graph. From that storage, the graph can be used to generate displays for users interested in learning about the graph and/or for performing queries and the like on that graph data.

Abstract: Navigation instructions are determined using visual data or other sensory information. Individual frames can be extracted from video data, captured from passes through an environment, to generate a sequence of image frames. The frames are processed using a feature extractor to generate frame-specific feature vectors. Image triplets are generated, including a representative image frame (or corresponding feature vector), a similar image frame adjacent in the sequence, and a disparate image frame that is separated by a number of frames in the sequence. The embedding network is trained using the triplets. Image data for a current position and a target destination can then be provided as input to the trained embedding model, which outputs a navigation vector indicating a direction and distance over which the vehicle is to be navigated in the physical environment.

Abstract: The goal of the METHOD FOR ENVIRONMENTAL ANALYSIS AND CONTROL OF SPATIAL AREAS as a continuation of “The Spatial Environmental Control Unit” is a method of logging multi-spectral, multi-pixel infrared radiation data of objects in a spatial area for the analysis and control of heat transfer dynamics in the spatial area that is responsive to feedback for controlling the thermal conditions in the spatial area. The METHOD FOR ENVIRONMENTAL ANALYSIS AND CONTROL OF SPATIAL AREAS further makes the current norm of an “absolute” temperature control approach for thermal control and human comfort obsolete. Ambient environmental conditions and user preference variables makes the current approach to thermal control time consuming, inaccurate and tedious. The Spatial Environmental Control Unit as one of our foundation patents disclosed the physical components make thermal control and analysis more responsive and user friendly.
