...gyroscopically stabilized platforms that tilted to compensate for any disturbing motion. But the platforms weighed hundreds of pounds and were both expensive and difficult to install. So engineers at the Dynasciences Corp. in Blue Bell, Pa., decided to take a radically new approach. Instead of steadying the viewing instrument, they decided, it might be more practical to stabilize the image by bending light beams from the target so that they would always hit the camera film or the retina of the viewer's eye at the same point. Using this concept, the Pennsylvania company developed a portable system that...
When an optical instrument is shaken or moved, two tiny gyroscopes in the Dynalens collar sense the motion and send signals that control miniature electric motors connected to the glass plates at each end of the prism. The motors, which respond almost instantaneously to movements of the optical instrument, tilt the plates to change the shape of the prism, thus bending the incoming light beams just enough to compensate for the motion. The result is a clear and remarkably steady image...
...total war, the prison camp has become an extension of the battlefield. Totalitarian nations are not content merely to extract information from a P.O.W. They often hound and harass a man for months and even years in order to win his mind and soul, to reduce him to an instrument of propaganda. It is, of course, a tactic that the Soviet Union devised for use against its own political prisoners, as dramatized with terrifying realism in Arthur Koestler's Darkness at Noon...
...more than a year, pilots of commercial flights serving the southeastern U.S. have carried in their chart bags an approach map for Havana's Jose Marti International Airport, showing electronic navigation aids and the course for an instrument landing approach. The Federal Aviation Agency's Miami Traffic Control Center notifies Havana of the skyjacking. An official of the Swiss embassy in Washington-which handles U.S. diplomatic contacts with Fidel Castro's Cuba-fills in the blanks on a prepared form asking the Cubans for prompt release of the aircraft and its passengers. U.S. air carriers in Miami...
...skyjacker who tried to take over the jet on its final landing approach to Miami International. No one has attempted to disarm a skyjacker. A single bullet fired through the fuselage of a pressurized airliner will not necessarily result in explosive decompression, but one shot in the instrument-packed cockpit could bring disaster even if none of the crew were...
