Abstract: This invention is an apparatus consisting of components that can be assembled and reassembled in various configurations allowing students to perform multiple physics and engineering experiments, with sensors and electronics integrated into the apparatus that allowing extraction of data via integrated data links, while computing and displaying results graphically in near real time. The principal component of the system is a linear drive system with a movable carriage, the position of which is measureable by various rotary and linear encoders. Load cells are able to measure forces of compression and tension. Temperature and Pressure sensors are able to measure gas pressure and the thermal conductivity of materials. The various components of this flexible educational tool can be disassembled and stored in a portable “toolkit”, the size of a small briefcase.

Abstract: This invention provides new above knee (AK) and below the knee (BK) orthotic devices and implements specific manufacturing processes for the production of orthotic devices through the automated, computer controlled bi-axial and tri-axial braiding of orthotic devices, over a mold or mandrel made of carved foam, plaster material or wax that is a replica of the patient's limb, and is created by a Computer Aided Design (CAD) file controlling a Numerically Controlled (CNC) machine tool. This method of manufacture using aerospace fibers such as graphite or Kevlar, and high performance resins, is used to create a orthotic device which is stronger and lighter weight than conventionally manufactured orthotic devices. Braiding also allows incorporation of woven cloth, tapes and other reinforcements into the braiding process for added strength at selected areas. The method dramatically decreases the production time and cost of the relative to conventional methods.

Abstract: The present invention relates to standardizing the manufacture above-the-knee (AK) and below-the-knee (BK) prosthetic sockets and attached hardware using specially designs alignment jigs that can record position of components, with micro-encoders embedded in the jig, to quantify various degrees of freedom (rotations and translations) during integration of a temporary check socket or prosthesis. These records, together with a digital record of the shape of the truncated limb, in the form of a CAD file, can provide a complete digital record or “prescription” of the prosthesis. The digital record is then transferable to a central fabrication facility which uses a jig augmented with motors, drives systems, and encoders to robotically position and align fixtures and clamps to streamline integration and production of the prosthesis in a standardized manner.
