Abstract: Implementations described herein relate to training and refining robotic control policies using imitation learning techniques. A robotic control policy can be initially trained based on human demonstrations of various robotic tasks. Further, the robotic control policy can be refined based on human interventions while a robot is performing a robotic task. In some implementations, the robotic control policy may determine whether the robot will fail in performance of the robotic task, and prompt a human to intervene in performance of the robotic task. In additional or alternative implementations, a representation of the sequence of actions can be visually rendered for presentation to the human can proactively intervene in performance of the robotic task.

Abstract: A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft, the compartment being sized to receive the prosthetic heart valve in a collapsed condition. The inner shaft and the distal sheath may be movable relative to one another. The delivery device may also include a tube member and an outer sleeve overlying the tube member. The tube member may be configured to rotate or twist upon axial movement of the outer sleeve with respect to the tube member, the rotation or twisting of the tube member configured to rotate the prosthetic heart valve when the prosthetic heart valve is received within the compartment in the collapsed condition.

Abstract: The present invention is directed to a computer-implemented method of automatically identifying the presence of one or more elements in a sample via optical emission spectroscopy.

Abstract: A system, method, and computer-readable medium for generating factual and/or counterfactual data are described. This may have the effect of improving the complexity of data available for training machine learning models. The models may include, but not limited to, a probabilistic graphical model (PGM) and/or an agent-based model (ABM). Further aspects may provide for scrubbing actual data to create a data model that does not reveal the content of the underlying source data. Yet further aspects may provide for validating a data model.

Abstract: A method for interlocking precast concrete sections to create a unified whole. The method allows precast pieces to be substituted for in situ castings in certain applications. Each precast concrete piece has an interlocking feature. The interlocking features are pierced by at least one transverse opening. Once the transverse openings are aligned, a user pours a solidifying substance such as wet concrete into the aligned transverse holes. A reinforcing metal bar may also be placed in the holes. Once the concrete hardens, the precast pieces are linked together.

Abstract: Webs carrying RFID antennas RFID modules support high-speed mass production of RFID tags. Preferably, a sprocketed web having a sequence of sprocket holes near at least one margin to be engaged by a sprocket drive in a machine carries a sequence of RFID antennas, and another sprocketed web carries a sequence of RFID modules. Each web may be advanced past a forming station at which a module is separated from its web and attached to an antenna on the other web. The process produces a web of assembled and packaged RFID tags. Optionally, during the process, before RFID modules are attached to antennas, data may be written to each modules and then read and verified prior to the forming station in order to test each module. A module with data failing verification may be removed from the process without being attached to an antenna.

Abstract: A multi-exercise machine includes a frame, a resistance system, a seat connected to the frame to be movable from a first seat position to a second seat position, and an inclined post inclined in a selected direction. The configuration of the present invention provides the multi-exercise machine with a movable seat to create more space for correct ergonomic posture of a user in a standing position. The configuration of the present invention also provides the multi-exercise machine with an inclined post to enable correct ergonomic postures of a user in a sitting position. The present invention enables a user to perform a variety of exercises in both sitting and standing positions.

Abstract: Products are dispensed from a dispensing apparatus in which products marked with transaction information are received in a two-dimensional array of moveable bins. In response to control information synthesized from transaction information on the products in the bins and a dispense request, the array is operated to place a bin at a dispensing station on the dispensing apparatus. At the dispensing station, a mechanism is operated in response to the control information to provide access to the bin. A product in the bin may then be retrieved.

Abstract: Products are dispensed from a dispensing apparatus in which products marked with transaction information are received in a chain of bins. In response to control information synthesized from transaction information on the products in the bins and a dispense request, the chain is moved to place a bin at a dispensing station on the dispensing apparatus. At the dispensing station, a mechanism is operated in response to the control information to provide access to the bin. A product in the bin may then be retrieved.
