Design Of A Pool Access Device, Linjun Bu, Patrick Graham May 2013

Design Of A Pool Access Device, Linjun Bu, Patrick Graham

Assistive Technology Resource Center Projects

A pool chair was designed using the 2010 ADA standards for accessible design. The design uses a parallel four-bar linkage mechanism and is able to lift the chair with an average weight person in and out of the pool. The motion of the design has been analyzed. The motion is achieved by an electronic linear actuator. The analysis of the motion of this design yields reasonable transmission angles of 73° to 110°.


Design Of A Powered Hand Orthosis, Elyssa Dorenfeld, Robert Wolf, Stephan Zeveska Apr 2013

Design Of A Powered Hand Orthosis, Elyssa Dorenfeld, Robert Wolf, Stephan Zeveska

Assistive Technology Resource Center Projects

The goal of this project was to design and manufacture a fully functional powered hand orthosis, controlled and operated by the contralateral hand, and used by people with diminished hand functions. Linear actuators were used to create the movement of the fingers through a six-bar linkage. The design reduces the twenty seven degrees of freedom in a healthy human hand to six and replicates the motions needed to perform the most common grips including the cylindrical, pinch, and key grips. Results showed that a single finger could exert a force of 50N. This correlates to an approximate hand strength of ...

Motorsports Safety, Anthony Begins, Korapat Lamsam, Kerrie Maron

Assistive Technology Resource Center Projects

The prevalence of neck injuries and basilar skull fractures in motorsports caused many sanctioning bodies in top-tier auto-racing divisions to mandate the use of head and neck restraints. Current devices inhibit drivers from exiting the car in emergencies, such as a fire or situation where emergency medical personnel are needed. The Motorsports Safety group designed and prototyped a new head and neck restraint device that can be removed easily while wearing a racing helmet by releasing a wing via a quick release mechanism. Evaluation of the prototype demonstrated that the time to remove the device via the quick release was ...


Shoulder Mount For A Wearable Arm Orthosis, Richard Downey, Nikole Dunn, Adam Hoyt Apr 2013

Shoulder Mount For A Wearable Arm Orthosis, Richard Downey, Nikole Dunn, Adam Hoyt

Assistive Technology Resource Center Projects

Functionality of the upper limb is vital for performing Activities of Daily Living (ADLs) such as bathing, dressing, and eating. The goal of this project was to design, manufacture, test, and evaluate a shoulder mount to be used in conjunction with a powered, upper-limb orthosis. A prototype was developed that allows completion of all necessary ADLs, is user-friendly, and does not significantly increase the user’s body frame. On average, the device limits the user’s shoulder flexion and abduction by approximately 43% and 50%, respectively, and is reasonably adjustable to both male and female users in the 25th to ...
