Expanding the reach of robotics

11/29/11 — From flying and crawling through quake-ravaged wreckage to performing dexterous feats of minimally invasive surgery and enabling paraplegics to walk, the vision of what robots and intelligent machines can do has come a long way since I first began the robotics effort at Berkeley in 1983.

A Cal ‘Kinect-ion’

11/29/11 — In the fall of 2008, Jack Kang (B.S'04 EECS) was settling into a new marketing position at Marvell, a Santa Clara-based semiconductor company, when Microsoft came knocking with a mysterious assignment for the company. Working on an undisclosed product, the computing giant needed a team to design a complex chip for manufacture on a massive scale. “This project was very secretive,” recalls Kang. Many months into the development of a specialized microprocessor, he got his answer. The mystery chip was destined for Kinect, Microsoft's controller-free and immensely popular electronic game sensor device.

Berkeley Lab research sparks record-breaking solar cell performances

11/07/11 Berkeley Lab — Theoretical research by scientists at LBNL has led to record-breaking sunlight-to-electricity conversion efficiencies in solar cells. The researchers showed that, contrary to conventional scientific wisdom, the key to boosting solar cell efficiency is not absorbing more photons but emitting more photons. "A great solar cell also needs to be a great Light Emitting Diode," says Eli Yablonovitch, the UC Berkeley professor of electrical engineering who led this research.

Seeds of social change

10/17/11 — In Vietnam, less than five percent of women finish college-often because they can't afford the relatively small fees. Without skills, many young women have no choice but to take work that pays poverty-level wages. But thanks to a Seattle startup called Vittana, the brainchild of EECS alum Kushal Chakrabarti (B.S'04 EECS), some will benefit from a micro-loan that finances their education. "Education is the single most powerful tool we have to fight global poverty, enrich communities and transform lives," says Chakrabarti.

An intelligent approach to mobile news

09/12/11 — Do you read news on your cell phone? According to a 2010 Pew Research Center study, 33 percent of cell phone owners now check news, weather and sports headlines on their mobile phones. Yet searching for and reading news on a 3.5-inch screen isn't easy. Earlier this year, EECS Ph.D. students Taylor Berg-Kirkpatrick and Mohit Bansal teamed up on a project that may alleviate the problem.

To catch a speeding bullet

08/18/11 — In 1992, East Palo Alto, a city of 24,000 on the San Francisco Peninsula, logged the highest homicide rate in the nation per capita. The sounds of gunfire worried Robert Showen (B.S'65 EECS), who worked at SRI International in Menlo Park, just two miles from East Palo Alto's border. Showen specialized in acoustics and radio wave propagation, and it occurred to him: What if technology could locate the gunfire and tell police where it's coming from? Today, Showen's ShotSpotter systems are located in more than 70 sites across the nation and around the world. Think of a ShotSpotter system as an electronic citizen calling 9-1-1.

At Qualcomm, rise of founder’s son defies hazards of succession

06/12/11 The New York Times — When Paul E. Jacobs took over from his father as chief executive of the chip maker Qualcomm in 2005, mobile phones were just beginning their transition from tools for talking to hand-held computers delivering data and entertainment. "We talk about the future of computing being mobile, but I don't feel that way," said Mr. Jacobs, 48. "I feel the present of computing is mobile." Mr. Jacobs received his Ph.D. in electrical engineering and computer sciences from UC Berkeley and is the current chairman of the UC Berkeley College of Engineering Advisory Board.

A pillow fight on auto-pilot

06/07/11 — The breezeway between McLaughlin and O'Brien halls looks like an electronic components store after an explosion. Color-coded wires, screwdrivers, white sprockets and power tools litter the floor-wherever there isn't a student standing, squatting or lying. In teams of fives and sixes, these local high school engineers are working hard to build robots for the final competition of Pioneers in Engineering (PiE), a robotics competition run by Berkeley Engineering students.

The origins of Intel’s new transistor, and its future: Q&A with Chenming Hu

05/09/11 IEEE Spectrum — Intel has announced a big change to the electronic switches at the heart of its CPUs. Going forward, the firm will be using three-dimensional transistors to take the place of long-used planar devices. The new transistors are a variation on the FinFET, a transistor design that substitutes the flat channel through which electrons flow with a 3-D fin. How did this 3-D design win its way into production? Spectrum asked the coinventor of the FinFET, Chenming Hu, a professor emeritus at UC Berkeley, how the new transistors got their start.

Building the bio toolkit

05/04/11 — In the 1970s, the Berkeley-bred SPICE (Simulation Program with Integrated Circuit Emphasis) revolutionized microelectronics by creating a toolkit now used worldwide as the standard for circuit design. Our new Synthetic Biology Institute (SBI), launched on April 25, aims to repeat this feat with biological and chemical engineering.

Sun-driven and Australia-bound

05/04/11 — To build a car powered completely by the sun, a team of Berkeley students is burning lots of midnight oil. A year-and-a-half in the making, a sleek vehicle called Impulse was unveiled at Cal Day and is on track to compete in the world's premier solar car race this October. Behind the effort is the 73-member crew of CalSol, the campus's student-run solar vehicle team. This fall, 15 to 20 students will withdraw from school for the semester to participate in CalSol's first-ever entry in the World Solar Challenge, an 1,800-mile road race across Australia.

Security in a networked world

03/02/11 — Nearly two billion people-more than the population of China-now use the Internet. With its vast capacity for communication and information, the web has become a powerful tool for transformative change: from new financial services and poverty alleviation to political change, as we are seeing in North Africa and the Arabian Peninsula.

Engineers applaud as Watson beats humans in Jeopardy!

02/17/11 New Scientist — In the battle between human and machine, our silicon opponents just notched up another victory. The new digital champ is Watson, a supercomputer designed by IBM to play Jeopardy!, a US quiz game famous for its strangely worded clues. The 200 or so engineers who watched the final show in an auditorium at UC Berkeley revealed in a show of hands that around three-quarters of the audience were rooting for Watson. "It's fun to see a computer beat a human," said one student. IBM was represented by Jean Paul Jacob, a computer scientist who spent 42 years at the company and who also holds a position at CITRIS at Berkeley.

Laser-quick data transfer

02/14/11 Technology Review — Researchers have learned how to make lasers directly on microchips. The result could be computers that download large files much more quickly. Connie Chang-Hasnain, professor of electrical engineering and computer sciences at UC Berkeley, has overcome the incompatibility between silicon and laser materials by taking advantage of the properties of nanostructures and by carefully controlling the growth process.
