Device For Affixation Of Rear-Facing Child Restraint System To Ambulance Cot For Non-Emergent Transport, Matthew Miller, Kendall Rogoff, Troy Kohler, Lily Buchanan
Honors Theses
During motor vehicle travel it is a near-universal practice to transport infants in a rear-facing car seat, formally known as a child restraint system (CRS). Car seats are subject to heavy regulations, extensive testing, and are safe, secure, and familiar environments for infants. The use of a CRS reduces fatalities associated with motor vehicle collisions by up to 71%. Current devices on the market for pre-hospital infant transport are harness-based and do not utilize these car seats. Aversion to use of these harnesses occurs for a variety of reasons. The device becomes visually unattractive after remaining in storage for long …
Development Of Biomechanical Analysis Techniques For Fatigue Of Transtibial Prosthetic Socket And Pylon Interactions, Thomas Z. Sudbury
Development Of Biomechanical Analysis Techniques For Fatigue Of Transtibial Prosthetic Socket And Pylon Interactions, Thomas Z. Sudbury
Honors Theses
The lack of formal, engineering based information is prevalent in the prosthetic industry. Currently, very few prosthetic manufacturing companies can definitively tell their patients how long their products will last. Because of this lack of information, many amputee patients will experience failure of their transtibial prosthetic device during daily activities. One such failure occurs from the fatigue of everyday use. Fatigue failures originate from the repeated application of certain loading conditions. These repeated loads usually occur for millions of cycles before a transtibial prosthetic catastrophically fails. The purpose of this study is to develop a testing procedure and apparatus that …

Subtalar Fusion Fixture Design And Test, Nathan Ortiz
Honors Theses
Subtalar arthrodesis is performed when cartilage in the talo-calcaneal (the ankle) joint is degraded in a patient and there are multiple approaches to this surgery. Using synthetic bone material, fixtures were cast from aluminum, using the process of evaporation pattern casting, and epoxy. This casting was used to grip the calcaneus bone of the foot in order to load it mechanically, simulating different scenarios that would be encountered during walking. The relative displacement of the ankle joint was measured using a digital image correlation (DIC) program that was modified to work in both two- and three-dimensional space. This program can …
