Accomplishments, New Opportunities and Challenges
--Ruzena Bajcsy

In this presentation we shall first describe the genesis of the Center, its scientific goals and organization. The second half describes the most recent technical accomplishments, notably related to the network of MOTEs, and their applications.

A MOTE is an assembly of sensors, a small computer and a radio. It has the capability of sensing some physical property, such as temperature, light, velocity or acceleration, chemical sensors, strain gage sensor and their like. The computer has a small operating system, called TinyOS, which enables the user to program and control some of their activity. The radio transmits the sensed and processed information in 36 byte packets. The MOTEs operate on 2AA batteries.

We shall present several examples of applications of these reconfigurable networks. However we shall also show the outstanding technical problems and issues of privacy and reliability.

AI Goes Quantitative
--Michael Jordan

In recent years AI has become more of an engineering discipline, aiming at solving real-world problems, and more tightly integrated with other areas of engineering and computer science. Superficially, the change is heralded by the increasing presence of vectors and matrices on AI researchers' whiteboards, but more deeply the change reflects the fact that AI researchers have embraced probability and statistics. The statistical nature of current AI makes it well equipped to exploit the increasingly copious data that are available to modern computers, and to cope with the uncertainty and noise inherent in real-world applications. I will describe a number of such applications and provide some hints as to the exciting algorithmic and mathematical developments behind them.

Great Moments in Computing Systems at Berkeley
--Dave Patterson

Berkeley has a proud tradition in Computer Systems, reflected in part by our top ranking in Systems by the most recent U.S. News and World Report. The projects are stories of both the technology innovations and the people who built them. I'll start the story telling with a few pictures that may be nostalgic to some of the audience, but I'm sure the that others in the audience will share their rememberances too.

IT in Fire Fighting: Better tools for those on the frontline
of home defense

--Paul Wright

This project began in a Berkeley class (sponsored by Ford, CITRIS and Intel) called “High Tech Product Design and Rapid Manufacturing”. The class was in progress when the shocking events of September 11th, 2001, took place. As a result, one of the design teams began to reformulate the communications and information systems needed in a large fire, based on the recognition that the heroes of that day did not have the equipment they needed and deserved. We have thus been creating wearable computing systems that are integrated into standard fire-fighting masks. We refer to them as “Heads Up Display (HUD)” units that can show the wearer a postage-stamp-size “You Are Here” map of the building-floor. The same map can be seen on the Fire Chiefs laptop as he or she coordinates the fire with the deployed fire crew. Using wireless sensor platforms as the research base, we have also created rudimentary ‘beacons’ for each fire fighter to wear. This allows each fire fighter to be tracked on the HUD-maps as a moving ‘red-dot.’ Such tracking allows further coordination with the Chief’s laptop that monitors the main location of fire and smoke. Improved designs of wireless smoke and CO alarms are also integral to the project and we will be powering these with some novel “energy scavenging devices” that will also be described in the presentation.
