  • The design and development of the wearable health and activity monitor

    Creator:
    Glover, Neil E.
    Abstract:
    This work describes the development of an accurate, low-cost, expandable and wearable health and activity monitoring platform. Wearable monitors used to track physical activity are becoming an increasingly popular and effective way to combat our dangerously sedentary lifestyles. Unfortunately most existing wearable solutions are either costly, inaccurate or cumbersome. The...

  • Testing of wave energy converters using the Ocean Sentinel Instrumentation Buoy

    Creator:
    Lettenmaier, Terrance
    Abstract:
    Ocean testing of Wave Energy Converter (WEC) prototypes is necessary to facilitate commercial WEC development. The Ocean Sentinel Instrumentation Buoy, completed in August 2012, provides a stand-alone load for WEC prototypes during ocean testing. The first part of this work was to develop the power conversion and data acquisition equipment...

  • Passive health monitoring with wirelessly powered medical devices

    Creator:
    House, Samuel
    Abstract:
    The proliferation of body worn autometric devices has been enabled by advances in low-power electronics and fueled by the quantified-self movement. These devices range in complexity from pedometers to clinical vital sign measurement. They all share the same drawback, typically the most expensive and heaviest component, the battery. The future...

  • On the study of WEC prototype advancement with consideration of real-time life extending control

    Creator:
    Stillinger, Chad J.
    Abstract:
    Renewable energy is a topic of significant interest and importance in the world today. Ocean wave energy, particularly in areas such as the Oregon Coast, has considerable potential as a renewable resource. However, to rightly evaluate the overall cost of energy for wave energy converters, survivability and maintenance issues must...

  • Multiple antenna techniques for pulse-based ultra-wideband system

    Creator:
    Vemulapalli, Sudheer
    Abstract:
    fIndoor wireless local area networks (LAN's) and personal area networks (PAN’s) have evolved very rapidly in the recent past. The indoor wireless LAN's are mainly dominated by narrow-band technologies like the IEEE 802.11a,b which are short range and provide data rates of 1 Mbps to 54 Mbps. The Bluetooth has...

  • Improved efficiency in medium-power flyback converters

    Creator:
    Ruttanapaibooncharoen, Surin
    Abstract:
    Switch-mode power supplies (SMPS's) not only convert energy, they also consume it. Typical operational efficiencies are approximately 25 to 60% for linear power supplies, and approximately 50-90% for switching power supplies. This means that products whose end-use electronics are dc, such as televisions and DVD players, could consume 50% less...

  • Hardware and software methods to improve and accelerate the development cycle of wave energy converters

    Creator:
    Tavakoli, Mike
    Abstract:
    With the ever-increasing demand and competition for global energy resources among nations, it is essential to explore and tap into various energy sources to reduce dependency on global markets. Renewable energy sources offer a significant opportunity to create localized and stable energy supplies. Ocean wave energy can be a promising...

  • Fabrication of Cost-effective Flexible Glucose Sensor for Continuous Glucose Monitoring

    Creator:
    Mullapudi, Sri Sai Kameswara
    Abstract:
    Diabetes is a pandemic that affects nearly 29.1 million Americans and the fourth leading cause of mortality in the US. Type 1 diabetes is a chronic condition which occurs due to little to no production of insulin by the pancreas. This form of diabetes requires constant monitoring of blood glucose...

  • Fabrication of a flexible glucose sensing catheter for human implantation

    Creator:
    Matthews, David J.
    Abstract:
    Flexible electronics processing techniques were applied to integrate a glucose sensor with a hormone-delivery catheter in order to create a cheap and minimally invasive method for patients with type 1 diabetes to continually monitor and control their blood sugar levels. Ultimately, this work intends to move toward the development of...

  • Development of a Collision Detection Module for Avian and Bat Species on Wind Turbine

    Creator:
    Davis, Cassandra L.
    Abstract:
    Renewable energy technology continues to grow in popularity as countries aim to reduce greenhouse gas emissions. Land based and offshore wind turbines are one option for expanding renewable energy sources. However, as wind energy adoption increases, so does the need for enhanced monitoring of wind turbines’ potential effect on local...
