  • Publication number: 20240106313
    Abstract: A linear motor including a stator assembly, an armature mechanically coupleable to a test specimen configured to be moved relative to the stator assembly by operation of the linear motor, and a suspension system configured facilitate movement of the armature relative to the stator assembly along an axis of movement without physically touching the armature during movement. Further disclosed is a multi-phase linear motor, a linear motor having an armature with an array of flat magnets, and a linear motor having a magnetic damping system.

  • Patent number: 11846609
    Abstract: An electric actuator includes a stationary support and a guide system having a single stationary guide joined to the stationary support having an axis. The actuator also includes a stationary assembly secured to the stationary support. A moving assembly is movable relative to the stationary support on the guide, where the moving assembly and the stationary assembly provide at least two sets of interacting magnetic fields disposed about the guide at equal angular intervals. A test specimen support is joined to the moving assembly and disposed on one side of the stationary support so as to move along the axis with movement of the moving assembly, the axis extending through the test specimen support.

  • Patent number: 10173044
    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.

  • Publication number: 20160032950
    Abstract: A mechanical clamping device can include at least two contact faces, a first of the contact faces configured to travel in response to an applied force, each contact face configured to contact a sample when loaded into the mechanical clamping device. The device can further include a load element configured to cause the two contact faces to apply a clamping force to the sample when loaded into the mechanical clamping device.
