Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: An electric drive axle of a vehicle includes an electric motor having an output shaft. An idler assembly is drivingly coupled to the electric motor and a differential. The idler assembly includes a first gear-clutch assembly to facilitate a first gear ratio and a second gear-clutch assembly to facilitate a second gear ratio.

Abstract: A litter lift system includes a winch and a lifting strap. The winch includes a rotatable spool. The lifting strap has one end coupled to the rotatable spool and is movable due to rotation of the rotatable spool. The lifting strap has a first lifting segment and a second lifting segment positioned away from the end of the lifting strap coupled to the rotatable spool. The first lifting segment and the second lifting segment are each forked to interface with a frame of a litter at first lifting segment and second lifting segment distal ends, wherein a coupling is attached to the first lifting segment. Rotation of the rotatable spool in a first direction raises the first lifting segment and the second lifting segment. Rotation of the rotatable spool in a second direction different from the first direction lowers the first lifting segment and the second lifting segment.

Abstract: An occlusion clip comprising: (a) a spring; (b) a first runner including a first open top and a first open end adjacent the first open top, the first runner including a first interior camming surface partially delineating a first interior cavity that is open by way of the first open top and the first open end; (c) a second runner including a second open top and a second open end adjacent the second open top, the second runner including a second interior camming surface partially delineating a second interior cavity that is open by way of the second open top and the second open end, where the spring is configured to be coupled to the first runner and the second runner, where the first interior cavity is configured to receive a first portion of the spring, where the second interior cavity is configured to receive a second portion of the spring, where the first camming surface is configured to engage a first cam of the spring, and where the second camming surface is configured to engage a second cam of the sprin

Abstract: A handle operably coupled to rotating door handle assembly is disclosed. The handle may include a first rotatable member configured to engage a door latch mechanism. The handle may further include a second member mechanically engaged with the first member and the second member may be extended a length between a non-extended position and an extended position. A handle cavity may be defined within at least a portion of the second member and a bar may be enclosed within the handle cavity. Furthermore, an extension mechanism may be incorporated with the bar and the second member and configured to extend the bar from the cavity when the second member is in the extended position and retract the bar within the cavity when the second member is in the non-extended position.

Abstract: A curtain wall system includes a vertical member and a horizontal member coupled to the vertical member at a joint. A vertical bridge gasket is coupled to the vertical member and includes a vertically-extending interior gasket, a vertically-extending thermal break gasket, and a vertical bridge member extending between the vertically-extending interior and thermal break gaskets. A horizontal bridge gasket is coupled to the horizontal member and joined to the vertical bridge gasket at a corner joint, the horizontal bridge gasket includes a horizontally-extending interior gasket, a horizontally-extending thermal break gasket, and a horizontal bridge member extending between the horizontally-extending interior and thermal break gaskets. The vertical and horizontal bridge gaskets cover the joint between the vertical and horizontal members.

Abstract: An apparatus, method and manufacture utilizes additive manufacturing techniques to produce architectural manufactures such as windows and doors. The manufactures may have a composite construction and may feature inclusions like metal plates and reinforcements. The model used for controlling the manufacturing process may be derived from digital scanning of the structure on which the manufacture is used. Optionally, a finite element analysis is used to test the model and alter it in response to stress and/or thermal requirements.

Abstract: A sliding door assembly includes a door panel, a frame that supports the door panel and includes a bottom member with a lower profile and a top member with an upper profile, wherein the lower profile and the upper profile are parallel to one another. A lower sliding assembly is operatively coupled to a bottom of the door panel and engages the lower profile, and an upper sliding assembly is operatively coupled to a top of the door panel and engages the upper profile. A gasket interposes the door panel and a portion of the frame when the door panel is in a sealed position. The door panel is movable between the sealed position, where the gasket creates a sealed interface between the door panel and the frame, and a sliding position, where the door panel is moved laterally relative to the frame while remaining substantially perpendicular to a floor.

Abstract: Various embodiments of the present disclosure address problems associated with non-uniform flow of cooling air by providing a turbine engine including a cooling air chamber in fluid communication with a cooling air source, a turbine chamber, and multiple conduits fluidly connecting the cooling air chamber and the turbine chamber. The system is configured such that, when cooling air is flowing from a cooling air source the static pressure within the cooling fluid chamber is substantially uniform and such that the mass flow rates of cooling air through the conduits and into the turbine chamber are substantially uniform.
