In a wide variety of manual labor industries, workers are often unaware that they are approaching dangerous vital thresholds until they have already overexerted themselves. According to a 2012 white paper by the Occupational Safety and Health Administration (OSHA), over 4,500 workers lose their lives, and more than 4 million are seriously injured each year. There is an immediate need to improve the safety and monitoring of manual workers to reduce the number of workplace injuries and fatalities. Millions of laborers around the globe go to work every day relying on basic safety devices, such as harnesses and steel ...


Reducing Fretting Corrosion At The Femoral Neck To Taper Junction In Total Hip Arthroplasty, Andrea M. Carly, Nicholas S. Moyer, Abel S. Pietros Jan 2016

Reducing Fretting Corrosion At The Femoral Neck To Taper Junction In Total Hip Arthroplasty, Andrea M. Carly, Nicholas S. Moyer, Abel S. Pietros

Fretting corrosion due to micromotion between the femoral head and neck of hip implants is a growing concern of surgeons and patients. Debris from corrosion can lead to severe adverse effects for patients of total hip arthroplasty and reduce the lifespan of the product. Previous studies conducted by Zimmer Biomet show a connection between higher impaction force and reduced fretting corrosion and debris. This design project explored this issue and developed a training device using a current technology, a dynamic force sensor, and data analysis software for surgeons to obtain muscle memory of a 4kN strike on the head impactor ...


A Software Application For Cardiac-Gated Computerized Tomography Scanning, Stephen Caldwell, Trevor Engelsman Jan 2016

A Software Application For Cardiac-Gated Computerized Tomography Scanning, Stephen Caldwell, Trevor Engelsman

Computerized tomography (CT) scans are a common clinical imaging procedure used worldwide. Operating in the X-Ray spectrum, these machines rotate scanners around a stationary body in order to compile two-dimensional images into a unified three-dimensional image. With adjustment to scan frequency and intensity, internal features such as muscles, organs, and tendons can easily be viewed. However, the heart has long evaded CT use due to its near-constant motion. Recently, cardiac-gated scans have entered the market as a technique to image the heart at a specific moment in time when it is nearly still - the quiescent period. Occurring during rapid depolarization ...


Pediatric Electrical Stimulation For Limb Lengthening: A Non-Invasive Approach, Corey J. Schurko, Sofia Chinchilla, Amanda E. Pinheiro, Jacob A. Brock Jan 2016

Leg Length Discrepancy (LLD) is a problematic ailment for children as the differences in limb lengths can lead to scoliosis, hip, knee, and ankle problems, and back pain. If LLD is untreated, the symptoms will worsen as the child matures. Today LLD is corrected by using the Ilizarov Method, which uses pins that are externally attached to the broken bone for extension over time using a fixator or by using internal plates that do not require externalization. In our project we aim to use external electrical stimulation to correct the limb discrepancies. Several companies, such as Zimmer Biomet, have created ...

This project is focused on creating a system to increase patient satisfaction in hospitals. My senior design team has been working hand in hand with the emergency department of Akron General to design this system called EMlighten. The goal is to create an experience for patients where they exit the hospital feeling more satisfied than they currently are. Patient satisfaction is a key performance indicator used by many hospitals to determine how much additional funding each hospital department is granted. If patients feel more satisfied, not only is that indicative of better care, but departments will receive extra funding. EMlighten ...


Hydroband: The Continuous Hydration Monitoring System, Karina E. Atkinson, Catherine P. Benedict Jan 2016

Hydroband: The Continuous Hydration Monitoring System, Karina E. Atkinson, Catherine P. Benedict

Dehydration is defined as a mild, moderate, or extreme loss of water in the body. It can result in fever, muscle cramps, headaches, dizziness, or heat stroke in athletes. Ways to determine hydration levels include analysis of the urine, blood, or sweat, body weight changes, skin elasticity tests, and increases in core temperature. Patent search, research journals, and outside studies in the health and fitness market showed that a convenient and continuous hydration monitoring system was not available. Changes in core body temperature proved to be the quickest way to measure hydration levels. The HydroBand system is geared towards athletes ...
