Abstract: An electrical nut assembly for coupling an electrical lug to an electrical post is disclosed. The electrical nut assembly comprises a compression fitting and a compression sleeve. The compression fitting comprises a material comprising a first yield strength and comprises an internal thread operable to electrically couple to the electrical post and a base surface configured to electrically couple to the electrical lug. The compression sleeve comprises a material comprising a second yield strength greater than the first yield strength and is sized to at least partially cover the compression fitting. The compression sleeve is configured to compress the compression fitting in a radial direction when fitted at least partially over the compression fitting and pressed or advanced axially towards the base surface and as the compression fitting makes contact with the electrical lug.

Abstract: A rear-loaded electronics array, comprising a first circuit board assembly comprising a rail and at least one slat assembly. The at least one slat assembly can be operable to be removed from the rail and replaced on the rail from a rearward position. A second circuit board assembly can comprise a rail and at least one slat assembly. The at least one slat assembly can be operable to be removed from the rail and replaced on the rail from a rearward position. The first circuit board assembly can be positioned adjacent the second circuit board assembly, and the first circuit board assembly can be coupled to the second circuit board assembly, thus forming the rear-loaded electronics array. The first and second circuit board assemblies can be installed and removed independent of one another, as well as each of the individual slat assemblies from any circuit board assembly.

Abstract: An anatomical model for simulating internal body structures of a patient, which in one embodiment includes a shell that simulates a body cavity and a length of animal tissue that simulates an organ in the body cavity. A sheath surrounds the animal tissue and is secured at one or more anchor points in the shell to support the animal tissue in the shell. In one embodiment, one or more force sensors are positioned to detect forces on the animal tissue or the shell.
