If you believe the prerelease hype, Sony’s PlayStation 3 is the machine that is going to change the way we experience games. This past May, gamers got a taste of some much-awaited PS3 titles during the E3 conference in Los Angeles. In Resistance: Fall of Man, a first-person shooter set in a devastated England overrun by creepy creatures, bullets zip and thunk with stunning clarity, and blood sprays with gruesome realism. In Heavenly Sword, tables and bodies fly as in a martial arts movie while you face enemy squads controlled by artificial intelligence algorithms. And in Gran Turismo HD, a dozen racing cars speed and skid through the streets of Tokyo or on a dusty rally circuit that has the Grand Canyon as a backdrop.

Sony Corp., in Tokyo, has a lot staked on the success of the PS3—hundreds of millions of dollars, at least, and maybe even its future as the preeminent maker of consumer electronics. “Gamers are expecting a great deal from the PS3, because Sony has promised a lot,” says Brian O’Rourke, an analyst at market research firm In-Stat, in Scottsdale, Ariz. “More realism, good online experience, new and innovative games are probably the primary expectations from gamers.” The console, after one big delay, is supposed to go on sale in Japan on 11 November, and in the United States and Europe on 17 November.

For more than 25 years, Rory Cooper has been developing technology to improve the lives of people with disabilities.

Cooper began his work after a spinal cord injury in 1980 left him paralyzed from the waist down. First he modified the back brace he was required to wear. He then turned to building a better wheelchair and came up with an electric-powered version that helped its user stand up. He eventually discovered biomedical engineering and was inspired to focus his career on developing assistive technology. His inventions have helped countless wheelchair users get around with more ease and comfort.

The next wave of Moore’s Law will rely on a developing concept called system technology co-optimization, Ann B. Kelleher, general manager of technology development at Intel told IEEE Spectrum in an interview ahead of her plenary talk at the 2022 IEEE Electron Device Meeting.

“Moore’s Law is about increasing the integration of functions,” says Kelleher. “As we look forward into the next 10 to 20 years, there’s a pipeline full of innovation” that will continue the cadence of improved products every two years. That path includes the usual continued improvements in semiconductor processes and design, but system technology co-optimization (STCO) will make the biggest difference.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Rohde & Schwarz

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
