A method for encrypted authentication of interchangeable parts of a surgical instrument includes providing a surgical end effector at a distal end of a handle of the surgical instrument and electrically connecting an authentication controller within the handle to a receiving portion of the end effector. An interchangeable part is removably placed at the receiving portion. The interchangeable part is authenticated with the authentication controller when the interchangeable part is seated in the end effector.

A portable therapeutic seat exercise apparatus and method that provide a lightweight personal exerciser designed for a person to use to improve physical status, and for the exercise, alignment, and stress reduction of a person's trunk, spine, abdomen, pelvis, and thighs. It encourages and enhances low back mobility in contrast to the static nature of regular sitting. It consists of a lightweight contoured seating surface supported by at least one arcuate hemispherical base that allows unrestricted motion in all directions, including twisting, tilting, and rocking. It can be placed on many seating surfaces including but not limited to sofas, dining chairs, school desk chairs, office chairs, factory benches, and motor vehicle seats. Its use facilitates low back muscular stabilization, conditioning, strengthening, coordination, and enhancement of proprioceptive senses. Interchangeable parts and add-on attachments can be used in differing combination to vary height, depth, position, and arc of the seat-supporting base.

An upper extremity prosthetic device is provided that comprises three main components, namely, an arm cuff, a forearm section and a distal connector. The arm cuff is adjustable to accommodate lower arms of different sizes. The forearm section may be constructed in certain limited sizes to accommodate different sized forearm residual limbs. The distal connector is designed to connect to any of the forearm section configurations, and the distal connector enables any terminal device to be attached to the connector. The components may be mixed and matched in various combinations to fit the physical dimensions of virtually any amputee. The interchangeable parts will accommodate a wide range of residual limb geometries, overall sizes and lengths. Embodiments of the present invention minimize the need for time and resource-intensive customized fitting and create an affordable, relatively low-cost prosthetic interface.

A tool support system is disclose having a yoke; a plurality of concentric rings having at least one ring pivotally connected to the yoke; a tool fastening mechanism to secure a tool in the support system; and one or more rotation components to permit the tool to rotate within a ring of the support structure. One or more of the concentric rings can be added to the system or can replace one or more concentric rings to accommodate tools of different sizes. The invention includes a method of configuring a support apparatus and a support apparatus kit with various interchangeable parts, and parts that can be built out to varying degrees to permit the support structure to be used on numerous types of tools.

A low frequency exponential bass horn enclosure employing a large area unitary throat pathway, bifurcated at a substantially parabolic rearward channel wall, convertible to a front-loaded or rear-loaded configuration by the use of interchangeable parts, with driver access from the front. Intended for corner placement, however, fully enclosed horn channel allows for floor use. The axially-centered throat expands vertically, exhausts rearward, and is bifurcated at the back of the enclosure with two hard reflection points, comprising a single fold, in which the vertically arranged horn terminus exhausts with a forward-canted splay angle around a partially rectangular back chamber.

The current invention comprises a mechanical enclosure capable of unifying a plurality of individual personal organization devices into one interchangeable platform. The apparatus maintains high spatial efficiency by use of materials and geometry allowing miscellaneous items to be carried in single compact space, while also allowing for convenient attachment and removal of modular elements for a variety of applications and uses.
