We would like to thank our instructor Carol Sevier, our lab instructor Eric Wallentine, and our lab assistant Kayla Wilson for all their help, suggestions, and encouragement. We would also like to express our thanks to Arvin and the others at the College of Engineering Student Shop, for being so willing to help with the fabrication of our project. Finally, we would like to thank Eileen for being such a great client, for being so cooperative and willing to frequently meet up with us for testing. We couldn't have done it without you!
