Abstract: A system for preserving or establishing an ecosystem comprises an assembly coupled to a guidance component. An assembly comprises an enclosure and a substrate, and is configured to contain one or more organisms within the enclosure. The guidance component causes the assembly to be transported to a destination environment. The assembly is decoupled from the guidance component. The assembly detaches from the substrate, to integrate the one or more organisms into an ecosystem of the destination environment.

Abstract: An underwater positioning system comprises a plurality of underwater beacons. A beacon, in response to a signal sent by an underwater vehicle, responds with a signal comprising one or more characteristics to identify the beacon. Components of an access algorithm are provided to the underwater vehicle. The access algorithm determines a location of the beacon based on the beacon's identity. A position of the vehicle is determined based at least in part on the location of the beacon.

Abstract: Systems and techniques for enhancing the physical games with augmented reality is described. A system identifies a characteristic of a physical object that is located on a physical surface. The system obtains, based on the characteristic, information indicative of a rule set for the game and a state of the game based on the characteristic. A game engine is initialized based on the rule set and game state. The game engine generates a subsequent state for the game. The system renders, based on the subsequent state, an augmented reality display that incorporates the physical surface and physical object.

Abstract: An augmented-reality system classifies a subject observed in video data obtained from a first area. A goal of a user of an augmented reality device is determined based on video data obtained from a second area. A correlation between the goal of the user and the classification of the subject is determined. An augmented reality display is generated to include a visual indicia of the subject, the visual indicia generated to represent the correlation between the goal and the classification.

Abstract: A system for recognizing gestures generates a skeletal model from video data of a subject. A defined subset of attributes of the skeletal model are mapped to defined positions of a vector. A gesture is recognized by evaluating a neural network using the vector as input. The neural network, trained using training vectors generated according to the definitions of skeletal model attributes and vector positions, classifies a gesture based on the input vector.

Abstract: A diagnostic model, adapted to a condition of a patient, is maintained. A monitoring device obtains visual information of a patient. The visual information is converted to a format suitable as input to the diagnostic model. Output of the diagnostic model is used to generate a recommendation for at least one of diagnosis or treatment of the patient. A response to the diagnosis or treatment recommendation is generated.
