Emerging Body Area Network standard, IEEE 802.15.6
Arthur Astrin, PhD

Area Networks (BAN) devices operate in close vicinity to, on, or inside body and can enable a wide range of applications, including medical support, healthcare monitoring and consumer electronics with increased convenience or comfort. Due to strong demands of medical, healthcare and information technology industries, IEEE was requested to standardize the Body Area Network. IEEE 802.15 task group 6 (TG6) was set up to develop an IEEE international standard for BAN in January 2008. This talk reviews major issues, history and current status of TG6. Early on, the TG6 invited representatives from industry to present applications which require body area networks. We then developed an application matrix, and summarized it into a single document, which was issued to proposers. The proposers were asked to propose a communication protocol that would accommodate this application summary document. The other issue facing TG6 was to have a detail understanding of available spectrum for BANs. And finally we needed at an accurate model of the channel; in this case the human body. This channel is much more difficult than free space/air to measure and to correctly model. The draft of the standard is in Sponsor Ballot stage and is being worked on by the team. We expect comments resolution in the next IEEE 802 meeting and completion of the standard in 2012.

Dr. Astrin received the Ph.D. E.E. from U.C.L.A. in Communication Engineering in 1984. He has worked for Apple Computer, Inc., IBM (100% club), Siemens, ROLM, Memorex and Citicorp in technical and management positions, where he developed several computer and communication systems. At Apple, he assisted in birthing the Wi-Fi industry, delivering first consumer oriented, wireless solution to the PC industry, AirPort, as well as creating industry compatibility with the Wi-Fi testing organization. In 1969 he built world's first DSP and hardware FFT processor. He also has been a professor at SJSU and UC Berkeley, teaching communication and computer engineering. Keeping one foot in academic world has allowed him to work on theoretical engineering problems, such as coexistence of Bluetooth and Wi-Fi wireless communications, as well as mentoring many students into the Silicon Valley industry. He is the Chair of the IEEE Information Theory Group in Santa Clara, a recipient of the IEEE Third Millennium Medal, the 2011 recipient of the Hans Karlsson award and a Senior Member of IEEE. He was a member of Bluetooth SIG and has been a member of IEEE 802.11/15 standards committee since 1997. He currently chairs the Body Area Network Task Group 6 of IEEE 802.15.

Decentralization of Care: The Circle of Enabling Technologies
Gregory T. A. Kovacs, M.D., Ph.D.
Stanford University

We are witnessing the ongoing decentralization of medical care, and three intertwined technologies are enabling this. First, information technologies &mdash storage, analysis and communication of medical data &mdash have grown ever more powerful and cost-effective. Computational advances in healthcare are manifold and potent, appearing across the continuum of handheld devices through cloud resources. Second, smart medical devices enabled by embedded computation are poised to become ubiquitous in the clinic and home, allowing for both contextual monitoring and titration of care. Lastly, molecular diagnostics have rapidly progressed from slow and manual tasks for humans to automated, fast and data-rich instruments delivering effective, quantitative clinical insights. Such advanced medical devices and diagnostic systems are poised to create a tsunami of data, which will be managed, interpreted and mined via application and advancement of computers. This will in turn enable the next generation of devices and diagnostics. That self-perpetuating circle of enabling technologies is opening the door for huge benefits for both ill and healthy populations and is the inevitable outcome of applying modern electronics to the problems of medicine.

Gregory T. A. Kovacs was born and raised in Vancouver, BC. He received a BASc degree in electrical engineering from the University of British Columbia, an MS degree in bioengineering from the University of California, Berkeley, a PhD in electrical engineering and an MD degree from Stanford University.

Since 1991 he has been a member of the Electrical Engineering faculty at Stanford University. His research areas include biomedical instruments and sensors, cardiac physiology, in vitro models for stem cell tissue repair, and medical diagnostics. He has co-founded several companies, including Cepheid in Sunnyvale, CA, a public company that develops and manufactures automated clinical nucleic acid diagnostics.

In 2003, he served as the Investigation Scientist for the debris team of the Columbia Accident Investigation Board, helping reconstruct the space vehicle to determine the cause of the mishap. From 2008 through 2010 he was Director of the Microelectronics Technology Office at the Defense Advanced Research Projects Agency (DARPA), leading his office's investment of approximately $600M/year in high-risk/high-payoff projects in electronics, sensors, photonics and medical devices.

Kovacs is a Fellow of the IEEE and of the American Institute for Medical and Biological Engineering. He received the Office of the Secretary of Defense Medal for Exceptional Public Service in 2010. He is a pilot, scuba diver, mountain climber, and a Fellow National of the Explorers Club.

NEW Technologies and Applications of Simulation in Healthcare
Sandra J. Feaster, RN, MS, MBA
Stanford University

Tour of the Goodman Immersive Learning Center in the Li KaShing Center for Learning and Knowledge in the Stanford School of Medicine

The last decade has seen explosive growth of technologies and applications of simulation in healthcare. This growth was based on a number of prior, often independent, developments of device and curricula. There is now a wide diversity of simulation methodologies ranging from low tech ones (verbal simulation, role-playing, using food products -- such as beef hearts and chickens-- for practice) to higher tech ones (part-task trainers, computerized mannequins) to truly high-tech ones (virtual reality). These have been linked to an equally wide diversity of applications.
This talk will provide an overview of the modalities and applications of simulation. There will be a brief review of some of the history and why healthcare is different from the analogous industries that have been used as models of simulation (aviation, nuclear power, spaceflight, military).

There will also be a detailed tour of the new 28,000 sq. ft. Goodman Immersive Learning Center in the LKSC. This center is the newest of 4 dedicated simulation centers at Stanford and its associated hospitals and opened its doors for teaching in late 2010. Stanford is one of the world leaders of all varieties of simulation in healthcare.

Ms. Feaster is the Assistant Dean for Immersive and Simulation-based Learning and the Director for the Center for Immersive and Simulation-based Learning (CISL - pronounced sizzle) at Stanford University School of Medicine in California. She is responsible for facilitating collaboration and coordination between all simulation activities and the four simulation facilities at Stanford University. She also has operational responsibly for the newly constructed 28,000 sq. ft. Goodman Immersive Learning Center in the Li-KaShing Center for Learning and Knowledge.
She is active in the Society for Simulation in Healthcare as vice-chair of the Public Affairs and Government Relations Committee as well as the co-chair for the Administration and Management Committee of the American College of Surgery Accredited Education Institutes.
Ms. Feaster has worked in several medical device and medical service companies in addition to her clinical work. She has a Master's Degree in Nursing and an MBA, and has completed course work in LEAN and Six Sigma at the black belt level.

Integrated Food and Activity Sensors Provide Behavioral Feedback for Successful Weight Loss with abiliti® Gastric Stimulation System in Obese Subjects
Rose Province
Principal Scientist: Intrapace, Inc

Obesity is a chronic disease which has become pandemic. The prevalence of worldwide obesity has more than doubled since 1980. In 2008, 1.5 billion adults were overweight. Of these 500 million were obese. While non-surgical management of obesity is favorable, numerous studies have shown that it is ineffective in producing and maintaining clinically significant weight loss. Surgical approaches are thus considered the only viable options for long term success in weight loss. There is a need for alternatives that are less invasive and devoid of severe complications. Gastric electrical stimulation (GES) has been recently introduced as an obesity treatment, and while clinical outcomes have been mixed, significant reductions in food intake and weight loss have been demonstrated. This talk will present the abiliti® system which was developed by Intrapace, Inc to treat obesity with GES, and in addition promotes behavioral change by providing consumption and physical activity data to patient and physicians. The intragastric and activity sensor technology will be discussed, as well as the clinical evaluation.

Rose Province received an MS in Biomedical Engineering from Johns Hopkins University in 1991. She has worked in the medical device industry for 20 years including the areas of cardiac rhythm management with St. Jude Medical, sleep apnea therapy with Inspiration, Inc., and at IntraPace, Inc in the area of obesity treatment. At IntraPace, her main involvement has been development of algorithms to provide exercise diagnostics from the implanted 3D accelerometer, and basic research to develop improved means for detecting food intake and enhance the efficacy of the gastric stimulation.
She does clinical and basic research to further develop medical device therapy, and is a named inventor in 10 patents related to defibrillation technology, and 3 patents in the area of breathing control with electrical stimulation.

3D Printing, Prosthetics, and Design: New Tools and New Opportunities
Scott Summit
Founder and CTO of Bespoke Innovations

The range of technology tools we call 3D Printing represent for more than merely new fabrication methods. Instead, they open the doors to an entirely new approach to product design, innovation, business, and problem solving for human needs. The vast flexibility now achievable in part design, and the natural dovetail with 3D body scanning, invite new approaches to addressing a broad range of musculo-skeletal needs. And as costs drop for 3D printing, it stands to grow ever more applicable to lower-income patients.

Scott Summit is an industrial designer and founder/CTO of Bespoke Innovations, a technology company researching applications where 3D scanning, parametric modeling, and 3d printing can solve human needs. Before Bespoke, Summit taught design at Carnegie Mellon and Stanford, and continues to lecture at Singularity University. Summit holds over 20 patents, and has designed products for Apple, Silicon Graphics, Palm and Nike.
