High Energy - Density Hydraulic Accumulator

Vanderbilt inventors propose an inexpensive and easy to manufacture hydraulic accumulator. The proposed hydraulic accumulator technology is intended for energy storage. It is superior to current alternatives in that it provides a simple, efficient and relatively cheap method for storing a large amount of energy in a relatively small volume and mass...

Split-Tube Flexure

This application describes the design of the split-tube flexure, a unique precision revolute joint that exhibits a considerably larger range of motion and significantly better multi-axis revolute joint characteristics than a conventional flexure. The development of this joint enables the implementation of spatially-loaded revolute joint-based preci...

Motion Generator to Transform Linear into Nutation Motion

A nutation motion generator which transforms linear motion into nutation motion. The device employs a spherical, four-bar linkage mechanism. Three four-bar linkage mechanisms are sandwiched between a stationary support surface and a drive plate and arranged at 120-degree intervals about the support surface. Each four-bar linkage mechanism is constr...

Stapes-Seat

New tool for insertion of stapes prosthesis. Holds prosthesis at user defined angle and has one-touch deployment. Advantage over current standard which is to use a surgical alligator (micrograpper). Allows easier insertion of stapes prosthesis by (1) single touch deployment, (2) 2-d site of contact between instrument and prosthesis (current stand...

Powered Leg Prosthesis

Nearly all current commercial transfemoral prostheses are energetically passive devices. That is, the joints of the prostheses either store or dissipate energy, but do not provide net power over a gait cycle. The inability to deliver joint power impairs the ability of these prostheses to restore many locomotive functions, including walking up stair...

A Robotic System for Real-time Tumor Manipulation During Image Guided Breast Biopsy

Three types of technologies have been developed for assisting during breast biopsy procedures. 1) Many robotic systems have been developed to improve accuracy of needle insertions. But these systems do not compensate for tumor movement during the insertion. Hence multiple insertions are typically required to successfully sample the tumor. 2) Steera...

Method and Apparatus for Energy Saving Pneumatic Positioning Systems

The solenoid-based technology provides a four-way valve and double-acting cylinder that are fully interchangeable with a standard four-way solenoid valve and double-acting cylinder combination, do not add significantly to the production costs of these components, and reduce the average airflow requirements by 40% relative to the standard combinatio...
