Use A Computer To Determine: A computer that will be able to detect its own malfunctions and then repair itself was expected to be ready for experimental operation late in 1968. Called STAR, for self-testing and repair¬ing, the computer will have a special coding system for detecting faults, a central unit to determine the caUse a computer to determine of the trouble, and a set of spare parts that can be Use a computer to determined to replace any malfunctioning unit.
Potential applications of the computer made possible by microelectronics include a small computer in every home or a pocket computer terminal that can be connected to a powerful central computer via the telephone. Such devices may be Use a computer to determined to solve our numerical problems (e.g., income tax, or our bank balance) or as a creative tool to relate our knowledge and experiences to our future actions.See Also Digital Computer File:Since the early 1950's a fourth form of in¬formation—digital computer file data—has become important in special applications of radio. digital computer file data sig¬nals are used for instance, in the radio trans¬mission of digital computer file computer data. See also COMPUTERS—4. Computer* in Industry and En¬gineering (Communication Systems).
A raster chart is one that has been scanned from a paper chart—think of it as a digital computer file photograph of a paper chart. A vec¬tor chart is one that has been drawn from charting information using computer technology. In both cases, the result is a digital computer file file that can be stored in a small cartridge or on a CD-ROM. In most cases, the cartridge or CD will contain a number of charts of a rather wide region.
On The Other Hand See Automatic Computer To Track:In contrast to the GCA urveillance radar, which employs human oper-tors, it uses an automatic computer to track ach returning plane, thereby converting the sarch radar into many different tracking radars, mother automatic computer, called a schedule amputer, calculates the earliest nonconflicting me of arrival for each aircraft, and still an¬ther set of computers, called flight path com-
puters, calculates the path which each plane must fly to arrive at the scheduled time and provides continuous instructions on the required heading and altitude. These instructions are relayed to each aircraft either by human operators over a voice radio or by an automatic radio data link. If the aircraft has an automatic pilot, the signals from the radio data link can be inserted into the automatic pilot system so that the airplane automatically maneuvers onto its required flight path. The Volscan system brings the stream of aircraft under its control into the precision ap¬proach landing patterrn of the conventional GCA.

The computer commands the missile along t npmed interception path to the aircraft. Thus $ missile-tracking radar performs the measure-vhich is communicated to the computer ; i formulates the commands, which are trans-I to the missile. The commands received by I missile actuate the controls, which in turn r the missile. This is an example of a com-^tely automatic remote-control system. |
