    Abstract: This document provides fluid handling components. For example, this document relates to taper interface connections such as, but not limited to, luer taper interface connections used to couple fluid handling components in a medical or laboratory setting. In some embodiments, the threaded connection on the male portion of the taper interface is comprised of one or two opposing tabs, rather than a 360° collar like conventional luer lock fittings. As such, the taper interface components provided herein are readily manufacturable with a lower cost than conventional fittings that have a collar. In some embodiments, the taper interface components provided herein are configured for coupling by way of a quick connection technique.

    Abstract: A chamber assembly for testing a valve includes a proximal chamber portion that defines a proximal interior space, and a distal chamber portion that defines a distal interior space. The distal interior space includes a gas space. When a liquid is inserted into the proximal and distal chambers there is an interface between the liquid and a gas in the gas space. A valve holder is disposed adjacent to the proximal interior space and the distal interior space. The valve holder is configured to receive the valve in a bore of the valve holder. A shortest distance between a center of the valve when in the bore and the interface is at least about 45 mm.

    Abstract: An apparatus includes an electric machine. The electric machine includes an internal housing, an armature coil disposed within the internal housing and separated from the internal housing by a gap, and a magnetic core associated with the armature coil. The apparatus also includes a fan configured to cause air to flow in the gap between the armature coil and the internal housing.

    Abstract: Systems, methods, and devices are provided for testing a drug eluting prosthesis. A drug eluting prosthesis is placed within a conduit that is coupled at one end to a first conduit frame and at a second end to a second conduit frame. The first conduit frame is coupled to the second conduit frame using a movable shaft, such that the first conduit frame and the second conduit frame can move relative to each other. When the first conduit frame and the second conduit frame are moved relative to each other, they expose the conduit and the drug eluting prosthesis to compressive or tensile forces. While the drug eluting prosthesis is being exposed to compressive or tensile forces, a fluid flow is provided through the conduit to test the particle shed rate of the drug eluting prosthesis.

    Abstract: In a mechanical test system, a method of compensating for acceleration induced load error in a load sensor in a mechanical communication with a component comprises measuring an acceleration of the component to obtain an acceleration measurement. A load sensor measures a force applied by the mechanical test system to a test sample in substantially a same direction of the acceleration to obtain a force measurement. The force measurement is modified with a transfer function that includes at least one of a gain correction and a phase correction to compensate for an error value in the force measurement attributed to movement of at least the load sensor when the force is applied to the test sample.
