Asian Contracts for $6 Million for Direction Finding Systems Announced by TCI International, Inc.SUNNYVALE, Calif.--(BUSINESS WIRE)--Aug. 20, 1997--TCI International, Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :TCII TCII Transcobalamin II TCII Technical Committee on Intelligent Informatics TCII Technical Committee on Information Infrastructure (IEEE) TCII TCI International, Inc. ) announced today that one of its subsidiaries, Technology for Communications International (TCI (Trustworthy Computing Initiative) An umbrella term from Microsoft for its efforts to improve security in Windows. TCI was announced in 2002 after viruses such as Code Red and Nimda had succeeded in attacking numerous Windows computers. ), has signed contracts totaling approximately $6 million to provide Direction Finding (DF) Systems to two customers in Asia. Both contracts are to be executed over the next 12 to 18 months. About DF Systems Direction finding systems enable the acquisition of information about radio transmissions, including their frequency and the location of the emitter. A DF system typically includes antennas, multichannel receivers, and specialized workstations that employ Digital Signal Processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). (DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive ) to perform the rapid calculations required to analyze raw signal data to yield useful information such as geolocation of the signal transmitter. DF tasks include scanning the electromagnetic spectrum electromagnetic spectrum Total range of frequencies or wavelengths of electromagnetic radiation. The spectrum ranges from waves of long wavelength (low frequency) to those of short wavelength (high frequency); it comprises, in order of increasing frequency (or decreasing for signals of interest, obtaining data about them, and displaying the results in various formats that enhance their interpretation by trained operators. Wireless communications are currently experiencing a period of explosive growth. DF systems -- a primary means of signal information collection -- have military and commercial applications. "The heart of a DF system is a digital processor," according to Dr. Miso Tkalcevic, Vice President for Advanced Development. "The TCI digital processor uses the TCI-proprietary Wavefront Noun 1. wavefront - (physics) an imaginary surface joining all points in space that are reached at the same instant by a wave propagating through a medium wave front Analysis DF algorithms to control a broad range of antennas and receivers and process data with unparalleled speed and accuracy." About TCI TCI International, Inc. is a holding company whose subsidiaries, Technology for Communications International and BR Communications, provide reliable and innovative systems of communications intelligence collection, specialized radio communication, broadcasting, and spectrum management. Founded 30 years ago in Silicon Valley in California to bring technological advances to the marketplace, TCI was the first company to use the computer in the design of antennas, and BR Communications invented the Chirpsounder, which provides real-time ionospheric measurement.
