Energy Harvesting Of Human Kinetic Movement, David Marusiak, Julia Carrillo
Electrical Engineering
Development of kinetic energy scavenging applications from the human body necessitates additional research to assist in designating a mounting position for a potential device. A data acquisition system adequately provides a parametric average power comparison among four locations on the body (waist, upper arm, hand, and calf) for both a male and female subject. Experimentally, the hand-held device provided the highest average power. Thus, subsequent investigation at set speeds provides further analysis of the output’s characteristically linear behavior. The physical energy-harvesting device features a plastic tube casing wrapped with the stationary coiled wire through which a neodymium magnet oscillates. While …

Polygrasp: Reach; Myoelectric Prosthetic Hand Iteration, Devon Patrick Augustus, Mighells Blaed Deuel, Ian Noel Fraser, Nicholas Philip Moesser
Mechanical Engineering
Amputations are a common occurrence in soldiers returning home who have suffered the effects of IED and munitions explosions. For upper limb amputees, trans-radial amputations are the most common. Traditional hook devices do not offer an adequate level of normalcy for users, prompting the use of myoelectric devices. While current myoelectric devices do offer a more natural experience, they come with a host of other problems that makes their adoption by service personnel not desirable or not permitted by the VA. PolyGrasp Reach seeks to reduce weight and cost and improve performance. This addresses several of the issues with devices …
Control System For Glucose Detector System, David Smith
Control System For Glucose Detector System, David Smith
Electrical Engineering
In this paper I design and test on a prove of concept level a control/timing circuit for a blood glucose detector built in a previous senior project. The specifications of the design given are to properly power the detector with a low power source. The design is completed on a transistor level basis using Cadence Virtuoso Software. The system is design from the ground up; designing, building, and testing smaller circuits first then combined into increasingly larger circuits till the completed circuit is finished. The design used to based off of the 555 Timer and uses differential pairs, CMOS designed …

Multi-Circle Detections For An Automatic Medical Diagnosis System, Dingran Lu
Master's Theses
Real-time multi-circle detection has been a challenging problem in the field of biomedical image processing, due to the variable sizes and non-ideal shapes of cells in microscopic images. In this study, two new multi-circle detection algorithms are developed to facilitate an automatic bladder cancer diagnosis system: one is a modified circular Hough Transform algorithm integrated with edge gradient information; and the other one is a stochastic search approach based on real valued artificial immune systems. Computer simulation results show both algorithms outperform traditional methods such as the Hough Transform and the geometric feature based method, in terms of both precision …
