Technology Research News August 11, 2004 Kimberly Patch	Projector lights radio tags The Radio Frequency Identity and Geometry system can be used in industry, health care, homes, offices, and libraries -- and in games to integrate real and virtual objects.
Technology Research News August 11, 2004 Eric Smalley	Cell phone melds video and data Researchers in Germany are attempting to bring augmented reality technology to the mass market. It could be practical in the next couple of years.
Technology Research News August 11, 2004 Kimberly Patch	Sound system lets listeners move The headphone-based system could be used in teleconferencing, surveillance and teleoperation so people can hear events as they happen. It could also be used in computer games, augmented reality systems, and industrial and military training.
Technology Research News August 11, 2004 Eric Smalley	Chips measure electron spin Practical quantum computers are at least a decade away, and some researchers are betting that they will never be built. But a pair of recent experiments may prove them wrong.
Technology Research News August 11, 2004	Twisted fiber filters light Researchers have devised a way to control light inside optical fiber communications lines. The method could enable faster data transmission rates in fiber-optic lines and new twists on devices like lasers and sensors.
Technology Research News August 11, 2004	Shifty tiles bring walking to VR A moving floor allows the user to stay in place while walking through a virtual environment. One application? Simulating disaster evacuations and similar operations, according to the researchers.
Technology Research News August 11, 2004	Speck trios make secret codes Researchers have devised a way to use quantum dots -- tiny bits of semiconductor -- to print invisible secret codes onto surfaces. The method could be used to authenticate valuable documents like passports and certificates.
Technology Research News August 11, 2004	Single gold atoms altered The gold atom, positioned on an ultrathin film of sodium chloride, remained stable during the operation, despite the change in charge.
Technology Research News August 11, 2004	Pen writes micro wires Researchers have devised a way to write stripes of gold onto glass to produce microscopic wires. The method could eventually be used to manufacture conductors for tiny electronic devices.
Technology Research News August 11, 2004	Design eases nano locomotion The lack of turbulence at small scales makes it difficult to travel through liquids. A new design could eventually be used to propel machines whose size is in the molecular realm.
