...four Pioneers that were launched into solar orbit between 1965 and 1968 to monitor interplanetary space, all are still transmitting scientific data-even though they were designed by Pioneer's prime contractor, TRW Inc., to last only six months; only one is experiencing some difficulty with a solar sensor. Signals are also still coming from Pioneer 10, which is now heading out of the solar system. Says Pioneer Project Scientist John H. Wolfe: "We now figure that if they make it for six months, they'll probably last forever...
...project, says Bricklin, began when he asked some frustrated designers from GM, Ford, Chrysler and American Motors to design a car that would handle well yet meet all federal safety and antipollution standards. The car, which looks something like a Maserati, has such safety features as a sensor device to prevent the car doors from closing if a passenger's hand gets in the way. Bricklin considered some 4,000 suggestions for a name, then insouciantly decided to call the car - what else?- the Bricklin...
...recall is doubly irritating for Chrysler because the part causing the trouble was modified on the assembly line at the insistence of the EPA in the first place. The part, designed by Chrysler engineers, is a sensor containing a ball of wax that softens when engine temperature rises to 60° F. The softening frees a valve that recirculates part of the car's exhaust gases through the engine and thereby eliminates some of the harmful nitrogen oxides that are emitted at high temperatures; when the temperature subsides, the wax ball hardens and closes the valve. At first, Chrysler...
Chrysler still maintains that the fire wall is the best place for the sensor. But, perhaps significantly, the company has not asked for permission to make the move back from radiator to fire wall. Instead, Chrysler will fit recalled cars free of charge with a redesigned sensor (retail price: $2) still located in the radiator. The new device consists of strips of metal that bend infallibly at 60° to open the recirculation valve. In other words, Chrysler has abandoned the whole ball...
...addition, the SAM6 is equipped with a heat sensor that can guide it to the aircraft's hot jet exhaust pipe. Finally, in its beam-riding mode, the SAM6 can be directed by its operator, who keeps the aiming dot of an electronic gun sight on the attacking aircraft. That is all it takes to send the missile accurately along a radar beam to the target. To make matters even worse for the enemy, the frequency of the missile's radar systems can be changed quickly, making it difficult to jam or confuse them with electronic countermeasures...
