Abstract: Computer-implemented methods and systems for processing recorded data for storage is provided. An auditable device, such as a digital video camera, stores a set of recorded data. The auditable device also stores auditable event entries that represent auditable events detected by the auditable device. One type of auditable event is the receipt of information from a computer-aided dispatch (CAD) system that indicates an event. The auditable device marks at least one subset of the set of recorded data based on the auditable event entries, and uploads the marked at least one subset of the set of recorded data to an evidence management system.

Abstract: A knockdown, portable lift is relatively compact and lightweight for transport and use where there is no existing means for lifting a load between a lower surface and an upper surface or where the existing means cannot be used. Components of the lift are stored in a base portion of the lift and are assembled on site for forming a lift frame extending between the upper and lower surfaces. A platform and drive assembly are supported on the lift frame and are driven together up and down tracks on each side of the lift frame using a rotary drive, such as a hand crank or electric motor, to power the drive assembly. The drive assembly is operable by a person on or off the platform from either the upper or lower surface or traversing stairs over which the platform is moving. The drive assembly incorporates a unique overspeed braking system and a unique clutch arrangement.

Abstract: Embodiments relate to in-situ process monitoring of a part being made via additive manufacturing. The process can involve capturing computed tomography (CT) scans of a post-built part. A neural network (NN) can be used during the build of a new part to process multi-modal sensor data. Spatial and temporal registration techniques can be used to align the data to x,y,z coordinates on the build plate. During the build of the part, the multi-modal sensor data can be superimposed on the build plate. Machine learning can be used to train the NN to correlate the sensor data to a defect label or a non-defect label by looking to certain patterns in the sensor data at the x,y,z location to identify a defect in the CT scan at x,y,z. The NN can then be used to predict where defects are or will occur during an actual build of a part.

Abstract: A prosthetic heart valve includes a frame, a valve, and an expansion element. The frame is movable between contracted and expanded configurations and includes first struts and second struts non-hingedly coupled together. The second struts are configured to pivot relative to the first struts as the frame moves between the contracted and expanded configurations. The valve is coupled to the frame and includes leaflets. The expansion element extends through a lumen of the first struts. The expansion element is slidable relative to the lumen of the first struts and is configured to move the frame incrementally from the contracted configuration and the expanded configuration and from the expanded configuration to the contracted configuration.

The increase in torque applied to the second shaft is configured to increase a rate at which a rotational speed of the second shaft decreases, e.g., in combination with the reduction in engine thrust or during the stall/surge of the engine.

The motor control circuit is for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end effector, and for adjustably controlling the electric motor based on the monitored parameter to thereby adjustably control movement of the moveable member of the end effector during forward rotation of the electric motor.

Abstract: Technologies are disclosed for dynamic authorization of users for distributed systems. A permission service allows authorized users to specify permissions for users of different systems, such as physical access security systems (PACS) and easier for users to interact with the authorized resources of the PACS. A manager may select a role for the user to specify the allowed permissions for the user. Changing the permissions/resources of a role automatically changes the permissions for users that are associated with the role. A scope may also be assigned to the user that specifies the locations of the physical resources that the user may access (e.g., a particular data center, a region, globally, . . . ). Instead of having to locate specific resources that the user is authorized to access, a graphical user interface (GUI) displays the authorized resources. When the resources change, the GUI is dynamically updated.

Abstract: Viscosity and other properties are determined at desired temperatures in drilling mud and other fluids by using a versatile cavitation device which, operating in the cavitation mode, mixes and heats the fluid to a specified temperature, and, operating in the shear mode, acts as a spindle for application of Couette principles to determine viscosity as a function of shear stress and shear rate. The invention obviates the practice of adjusting rheology of a drilling fluid by passing it through the drill bit. Drilling fluid may be managed by a “straight-through” method to the well, or by placing the cavitation device in a loop which isolates an aliquot of known volume and circulating the fluid through the loop including the cavitation device.
