Talking Signs solves this problem by providing a repeating, directionally selective message emanating from the sign. The message is sent from a transmitter via invisible infrared light beams to hand-held receivers that decode the signal into speech. To use a Talking Sign system, the user scans the environment with the receiver. As individual signals are encountered, the user hears the messages. Talking Signs are currently being used in San Francisco, New York, Austin, Texas and Washington, D.C., and internationally in Venice, Italy, and Yokohama, Japan.
Weather satellites no longer limit themselves to cloud formations.
The class, taught by Professor Christopher Simpson, teaches nontechnical students to read and interpret satellite images. The course is being offered both online and on campus. With Survey Controller 7.0 field software for TCI data collector and Trimble Survey Office software 1.5, it provides a powerful tool for data flow, flexibility and interoperability between GPS and optical instruments and a laser rangefinder for surveying any situation. The Georgia Institute of Technology is developing a computerized shirt embedded with a motherboard, fiber optics and special sensors that monitor the body's vital signs. Eventually, wireless transmission will allow the wearer to be monitored on the go, making it suitable for police and firefighters.
