Abstract: Systems and methods for delivering and implanting heart valves are disclosed. The delivery systems can include an integrated introducer. The integrated introducer can include a sheath having an inner diameter that is smaller than the outer diameter of a delivery capsule of the delivery system and an outer diameter that is approximately equal to the outer diameter of the delivery capsule. The integrated introducer can include a hub having a hemostatic seal. The hub can have a locking mechanism configured to fix the integrated introducer in place on the delivery system.

Abstract: An agricultural planting machine includes a frame and a planting system supported on the frame and configured to plant seeds in a row. The planting system includes a ground-engaging element movable relative to the frame and configured to engage a ground surface of a field. A field contour detection system is configured to receive in-situ sensor data representing a location of the ground-engaging element, generate field contour data representing a contour of the ground surface based on the in-situ sensor data, and generate a control signal based on the field contour data.

Abstract: Work machines, control systems for work machines, and methods of operating work machines are disclosed herein. A work machine includes a chassis, a header, and a control system. The header is coupled to the chassis and positioned to remove crop material from the ground. The header includes a reel to draw crop material into the header so that the crop material may be conveyed rearwardly and a plurality of actuators to move the reel relative to a frame of the header in use of the work machine. The control system is coupled to the chassis and includes a controller communicatively coupled to the plurality of actuators and a single user input communicatively coupled to the controller that is configured to provide an input signal to the controller.

Abstract: An agricultural combine (100) has a windrow control circuit that controls the profile of windrow (154) based upon signals received from a sensor (152).

Abstract: A shroud for the infeed section impeller in a rotary combine. The shroud includes a rear converging wall cone and a front diverging wall cone. A feed plate extends transversely across the front of the shroud and a sump is formed in the shroud behind the feed plate. The front diverging wall cone comprises top and bottom, rearwardly diverging walls. Transitions castings separate the top and bottom walls on left and right sides and have rearwardly converging front faces.

Abstract: The present invention relates to novel organocyanohydroborate compounds which may be employed as reducing agents. For example, organocyanohydroborates having the following general formula are contemplated:M.sup.+ BH.sub.3 CR.sub.1 R.sub.2 CN.sup.-In this formula, R.sub.1 and R.sub.2 may be, for example, H, CH.sub.3, or C.sub.6 H.sub.5, or may be represented jointly, for example by C.sub.5 H.sub.10, while M.sup.+ is a cation which is capable of forming a salt. The organocyanohydroborate compounds of the present invention include a --CR.sub.1 R.sub.2 -- moiety between the BH.sub.3 moiety and CN moiety to provide a new class of hydroborate reducing agents.
