Quick Pitch

This proposal describes a completely integrated wireless imaging system for mobile devices through the use of ultra-wideband technology.


With the current modalities available for cancerous tumor detection being based on expensive, harmful, and outdated technology, research into alternative modalities has become a hot topic. And with the emergence of the wireless age, ultra-wideband (UWB) technology has been viewed as a promising alternative due to its ability to be sensitive and very specific (detect only cancerous tumors), and the use of safer, non-ionizing radiation. UWB imaging is especially applicable to cancerous tumor detection in the breast, where it has been shown experimentally that the dielectric constant and conductivity of cancerous tumors in breasts may be three or more times larger than that of the host tissue. With UWB technology still in relative infancy, there are many issues impacting both the hardware and software aspects of the technology, especially if the UWB transceiver is to perform imaging via mobile devices. This proposal describes the complete design of an integrated wireless imaging system for mobile devices through the use of UWB technology. The hardware necessary to realize UWB capable transceivers suitable for mobile devices is described first, followed by a description of the software innovations necessary to extract images using the UWB transceivers. An artificial neural network is proposed to solve the software issues of the system. An analysis of the commercial viability of the UWB imaging system and target markets is then performed. A plan for the commercialization of the artifact is also discussed. Through the many advantages of UWB technology, the UWB transceiver is capable of reaching a myriad of markets, most notably the medical, military/law enforcement, and general consumer markets. Applications that make an integrated UWB transceiver popular are high data-rate wireless communication, networking, imaging, tracking, and localization.

Personal Statement

As a PhD student at UC, Berkeley and a researcher at the Berkeley Wireless Research Center, I have all the state-of-the-art resources (equipment and colleagues) necessary to realize the proposed idea. Several of my elder colleagues have won prestigious awards at premiere conferences for their designs of circuits optimized for UWB communication. My current research focuses on the use of delta-sigma modulators to perform high-speed A/D conversion for UWB capable transceivers. I have also worked at the Laboratory for Information and Decision Systems at MIT where I developed an algorithm to improve the ranging protocol of UWB transceivers used for UWB localization. I have interned twice at Qualcomm within its Analog/RF design group to design a clock and data recovery circuit and their first all-digital phase-locked loop prototype. While at Qualcomm I also won an employee-wide innovation challenge based on my idea and strategy for utilizing mobile devices to aid our everyday activities.
