Computer Data: Since the early 1950's a fourth form of information—digital data—has become important in special applications of radio. Digital data signals are used for instance, in the radio transmission of digital computer data. See also COMPUTERS—4. Computer* in Industry and Engineering (Communication Systems).
All data from the various tests are fed into a computer, which then compares the results with previously established standards. Several days later the computer data are all assembled, and the computer prints out for the physician a summary of all relevant information as well as comparisons with the results in previous examinations. At the end of the series of 20 steps in the center, the patient may be recommended for additional tests, for repeating certain tests if the results are unexpected, for immediate referral to his physician, or for a routine visit to his physician at a later date.
For indirect fire and fire at fast-moving targets, angle-measuring sights, oriented upon a reference point of known azimuth, are used to lay the gun in azimuth and elevation. Before the firing data can be applied to the gun, they first must be transmitted from the place of computation to the am. In most cases oral or telephone communi-itions are used; however, when a mechanical or metrical data computer is used, firing data are•nally transmitted electrically to the gun by jtkyn (synchro) motors. Servomechanisms on the gun receive these data and use them to position the gun automatically and continuouslv in zimuth and elevation, and to set on the fuze :-tter the required time of flight. |
