Annual competitions are held each year with a $2000 prize for the best program on a restricted Turing test. Sponsors of previous competitions include: Apple Computer, Computerland, Crown Industries, GDE Systems, IBM Personal Computer Company's Center for Natural Computing, Greenwich Capital Markets, Motorola, the National Science Foundation, The Alfred P. Sloan Foundation, and The Weingart Foundation. The 1995 and 1996 events were unrestricted Turing Tests, requiring computer entries to converse indefinitely with no topic restrictions. So far, even the best programs give themselves away almost immediately, either by simple grammatical mistakes or by repetition. Complete transcripts and IBM compatible diskettes that play the 1991, 1992, and 1993 conversations in real-time are available for purchase from the Cambridge Center for Behavioral Studies (telephone: +1 (617) 491 9020, Fax: 1072).

  • optical fibre — (communications)   (fibre optics, FO, US "fiber", light pipe) A plastic or glass (silicon dioxide) fibre no thicker than a human hair used to transmit information using infra-red or even visible light as the carrier (usually a laser). The light beam is an electromagnetic signal with a frequency in the range of 10^14 to 10^15 Hertz. Optical fibre is less susceptible to external noise than other transmission media, and is cheaper to make than copper wire, but it is much more difficult to connect. Optical fibres are difficult to tamper with (to monitor or inject data in the middle of a connection), making them appropriate for secure communications. The light beams do not escape from the medium because the material used provides total internal reflection. See also FDDI, Optical Carrier n, SONET.
