  • Ultra-Wideband Research and Implementation
    Ultra­Wideband Research and Implementation Senior Capstone Project 2007 Final Report by: Jarrod Cook Nathan Gove Project Advisors: Dr. Brian Huggins Dr. In Soo Ahn Dr. Prasad Shastry Abstract Ultra‐wideband (UWB) is a wireless transmission standard that will soon revolutionize consumer electronics. UWB is interesting because of its inherent low power consumption, high data rates of up to 480 Mbps, and large spatial capacity1. Furthermore, the power spectral density is low enough to prevent interference with other wireless services. This new standard has recently been approved by the FCC for unlicensed use and has been gaining interest throughout the consumer electronics industry. The main goal of the project is to increase interest in UWB technology, and to explore its usefulness. The history and benefits of UWB will be discussed, followed by the project goals, implementation, and results. Texas Instruments DSP platforms were used in conjunction with Simulink and Code Composter Studio to implement the scaled‐down baseband modulation scheme. Also, RF microwave components were donated from Hittite Corporation to perform quadrature modulation and up conversion to a frequency of 3.4 GHz. 1 Spatial capacity is defined as bits/sec/square‐meter. UWB is projected at having 6 devices working simultaneously within a 10 m range [16]. ii. Acknowledgements There are some people that need to be acknowledged for their work with this project. They include, but are not limited to: • Luke Vercimak and Karl Weyeneth for work on their 2006 Senior Capstone Project, Software Defined Radio. • Dr. Brian Huggins, Dr. In Soo Ahn and Dr. Prasad Shastry for advising, guidance and general encouragement throughout.

    Oral History of Avram Miller Interviewed by: Dane Elliot Recorded: August 19, 2013 Mountain View, California CHM Reference number: X6923.2014 © 2013 Computer History Museum Oral History of Avram Miller Elliot: All right. I’m here with Avram Miller today. It’s August 19, 2013. And we’re interviewing Avram specifically on how Intel invests in their future. Miller: How Intel invested in their Future Elliot: Very good. I’m Dane Elliot, and this is: Miller: Avram Miller. Elliot: Let’s start off with a little bit of background here. Miller: Okay. Elliot: And the background that I’d like to get is education and significant contributions in your career path that led you to Intel. So education? Miller: Well, I basically am self-educated. I always say that I graduated from Avram U. I studied music when I was in high school and then I became a Merchant Seaman for a while. Eventually, I got into science. I was always interested in electronics, and I started doing science at the University of California Medical School in San Francisco. Long story short, I ended up in Holland, at the Faculty of Medicine, Erasmus University. By the time I was 28, I was in an assistant professor in Medicine (medical informatics). When I was 29, I moved with my family to Israel where I was an Adjunct Associate Professor at the Medical Faculty of the University of Tel Avi and started up a medical computer business. What’s probably most relevant to our discussion is that I returned to the United States in 1979 and joined Digital Equipment Corporation.
