Abstract: A power head for a powered concrete roller screed includes a handle and a driver housing at a distal end of the handle. A cordless, battery-operated driver is received in the driver housing. A head actuator includes a translatable link extending along the handle and an eccentric cam. The eccentric cam is operatively connected to the translatable link within the drive housing such that translation of the translation link imparts rotation of the eccentric cam about a rotational axis of the eccentric cam to an actuated position. The eccentric cam is adjacent a trigger of a cordless, battery-operated driver and is configured to depress the trigger when the eccentric cam is rotated about its rotational axis to the actuated position.

The catheter assembly may include a first shaft around which a valve-receiving compartment is defined, the first shaft being operatively connected to the housing, and a distal sheath operatively connected to the piston, the distal sheath being moveable between a closed condition covering the compartment and an open condition uncovering the compartment. Longitudinal movement of the piston may move the distal sheath between the closed and open conditions.

Abstract: Methods and systems are provided herein for modifying playlists of media assets. In some aspects, these methods and systems are provided by way of receiving a user input that causes a media asset in a playlist to cease from being played back and to be removed from the playlist. User interactions associated with the playlist may subsequently be monitored, where, in response to detecting a user interaction while monitoring, a number of user interactions that have been received subsequent to the user input may be determined. The number of user interactions may be compared to a threshold number, and, when the number of user interactions corresponds to the threshold number, the media asset may be inserted into the playlist.

Abstract: A tangible, non-transitory machine-readable medium includes machine readable instructions that, when executed by processing circuitry, cause the processing circuitry to receive an inquiry regarding digital content. The inquiry is indicative of a request for the digital content or a request for a determination to be made regarding the digital content. The instructions, when executed, also cause the processing circuitry to process the inquiry by analyzing aggregated result data generated using a series of neural network layers based on the digital content and metadata associated with the digital content. Furthermore, the instructions, when executed, cause the processing circuitry to generate response data to the inquiry using a neural network based on analyzing the aggregated result data.

Abstract: A contract generation system that automatically generates cost models for new business contracts is provided. The system receives a new contract comprising a set of key-value pairs, each key-value pair comprising a question and an answer that correspond to a field of information in a document for the new contract. The system computes a similarity measure between the new contract and an existing contract based on a set of variance definitions for determining differences between the set of key-value pairs of the new contract and a corresponding set of key-value pairs of the existing contract. The system generates a cost model of the new contract based on the similarity measure and a cost model of the existing contract.

Abstract: A guidewire may be configured for insertion into a heart of a patient during a procedure such as a transcatheter aortic valve replacement procedure. The guidewire may include a proximal end and a distal end portion. The distal end portion may include (i) a leading section, (ii) a loop structure at a terminal distal end of the guidewire, and (iii) a transition section extending between the leading section and the loop structure. In the absence of applied forces, the leading section is not tangential to the loop structure. With such a configuration, the guidewire may avoid contact with the ventricular septum of the heart when the loop structure is seated within the left ventricle, which may mitigate potential interference with conduction pathways in the ventricular septum, which may in turn mitigate the need for a pacemaker.

Any embolic debris entering the bloodstream during the prosthetic heart valve deployment may be trapped within, or deflected by, the deployed embolic filter(s) to reduce the risk of stroke.

Abstract: Apparatuses, systems, and methods for determining and verifying operational states of fifth wheels. Certain methods for determining the operational state of the fifth wheel may include sensing, with at least one sensor, magnetic flux caused by a magnet on a movable component movable to lock the fifth wheel to a kingpin of a towed vehicle and determining an end position of the movable component based on the magnetic flux. The end position of the movable component is then compared to a threshold position and an operational state of the fifth wheel is determined based on the comparison of the end position of the movable component to the threshold position.
