Ros-Drill Automation: Visual Feedback Control And Rotational Motion Tracking, Jhon F. Diaz Aug 2011

Ros-Drill Automation: Visual Feedback Control And Rotational Motion Tracking, Jhon F. Diaz

Master's Theses

ICSI (intra-cytoplasmic sperm injection) has attracted research interest from both biological and engineering groups. The technology is constantly evolving to perform this procedure with precision and speed. One such development is the contribution of this thesis. We focus on a relatively recent procedure called Ros-Drill© (rotationally oscillating drill), of which the early versions have already been effectively utilized for the mice. In the first part, we present a procedure to automate a critical part of the operation: initiation of the rotational oscillation, Visual feedback is used to track the pipette tip. Predetermined species-specific penetration depth is successfully utilized …


Design Of A Pragmatic Test Lab For Evaluating And Testing Wireless Medical Devices For Deployment On An Integrated It Wireless Network, Allie Paquette May 2011

Design Of A Pragmatic Test Lab For Evaluating And Testing Wireless Medical Devices For Deployment On An Integrated It Wireless Network, Allie Paquette

Master's Theses

In today’s healthcare environment, networking of medical devices is becoming more and more prevalent. There is an increasing need for mobile technology to meet clinical needs. Wireless communication is essential for allowing medical devices to be able to move with the patient, while continuing to record and communicate patient data. A traditional example is telemetry monitoring, but other examples of wireless utilization include sending ECG test results to the EMR or remotely updating the drug library on numerous IV pumps. Each wireless application has varying demands on the connectivity infrastructure and will share radio frequency (RF) spectrum resources with a …


A Comparative Study Of Total Hemoglobin Measurement Technology: Noninvasive Pulse Co-Oximetry And Conventional Methods, Jared S. Ruckman May 2011

A Comparative Study Of Total Hemoglobin Measurement Technology: Noninvasive Pulse Co-Oximetry And Conventional Methods, Jared S. Ruckman

Master's Theses

Hemoglobin can be measured on a variety of devices using different principles of operation. Noninvasive pulse CO-oximetry represents the latest development in hemoglobin measuring technology. The technology uses principles similar to pulse oximetry to measure total hemoglobin, oxyhemoglobin, reduced oxyhemoglobin, carboxyhemoglobin and methemoglobin. Similar to the introduction of pulse oximetry to the medical field, pulse CO-oximetry has been met with skepticism. Since the technology is noninvasive and provides continuous monitoring in comparison to invasive and discrete techniques used in other methods, CO-oximetry purportedly provides an advantage in patient care. The purpose of this research is threefold: (a) to review the …


Noninvasive Assessment Of Joint Motion Over Long Durations: System Evaluation And Data Analysis Methods, Maria J. Qadri May 2011

Noninvasive Assessment Of Joint Motion Over Long Durations: System Evaluation And Data Analysis Methods, Maria J. Qadri

Master's Theses

The development, progression, and treatment of degenerative musculoskeletal diseases, such as carpal tunnel and shoulder impingement syndromes, may be better characterized when joint motions are assessed over long durations outside clinical, laboratory, or rehabilitation settings that involve standardized assessment, exercise protocols, and/or regimented movements. Assessment methods for human movement capture beyond laboratory or clinical experiments are typically limited to short capture times of less than one hour. Noninvasive, long-duration measurements of joint motion in occupational settings provides more insight into movement patterns and quantitative assessments regarding joint usage, which lead to a better understanding of the cumulative effects associated with …
