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.

Abstract: A bioreactor system includes a sample chamber capable of receiving a specimen and a cover which can be placed on the chamber to enclose the specimen within the chamber. A first member is movable between (i) a closed position in which the member restricts the cover from being moved away from the chamber in a first direction, and (ii) an open position in which the member does not restrict the cover from being moved away from the chamber. When the first member is in the closed position there is a substantially liquid proof seal between the cover and the chamber.

Abstract: This document provides mechanical seals that include one or more rolling diaphragms. In one example embodiment, this document provides double rolling diaphragm seals that are usable in conjunction with various types of equipment including, but not limited to, accelerated life testing systems. In such a context, the double rolling diaphragm seals facilitate high-speed linear modulation of a variable volume pressure vessel, while maintaining precise volumetric control. Such an arrangement can facilitate an essentially frictionless linear actuation system having a long stroke, long service life, and precise volumetric control. In addition, this document provides linear actuator systems that can be used in adverse environmental conditions.

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 electromagnetic motor includes a stator and an armature arranged to move substantially linearly relative to the stator in an intended direction during operation of the motor. A first and second flexure are connected to a first end of the armature. Each flexure has a longest portion which lies substantially in a plane that intersects a plane in which the armature lies at a substantially right angle. The flexures allow motion of the armature in the intended direction while resisting motion of the armature in one or more other degrees of freedom.

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.
