Fluorescent Light Transmitter - 12 September 2001
MIT professor and founder of Talking Lights Steven Leeb has developed a network that transmits data using the fluctuations of fluorescent lights to transmit data. A standard fluorescent light uses a magnetic ballast to regulate the flow of electricity to the light at 60 Hz, causing the lamp to dim 120 times per second. Newer electronic ballast increase the rate into the millisecond range. Leeb realized that the flicker rate no longer depended on the oscillation of electric current, he could control the flicker rate and transmit data both digitally by changing the flicker rate, and analog by adjusting the brightness of the light. A specialized receiver picks up the data signal and turns it into information. The demo system has a small black box receiver hooked up to two speakers. Leeb set up one of his specialized lights to transmit Handles Messiah to the receiver.
Leeb says the system can be used to direct the blind though a complex environment, such as an airport, or to transmit enhanced audio signals (for the hearing impaired) or captioning(for the Deaf) in an auditorium.
