...good buddies" are sure learnin' fast how to outfox Smokey the Bear. The sophisticated way to beat speeding tickets is to use a miniaturized radar-emission detector. Mounted on a dashboard, it flashes a light and then sounds a high-pitched beep when the vehicle approaches a radar trap. "This is the fastest-growing area of consumer electronics," says Cy Robinson of a Richardson, Texas, firm called Autotronics that sells "Snoopers" ($89.95) and "Super Snoopers" ($149.95). Super Snooper claims to be able to sniff out "over-the-hill and around-the-corner detection...
...imprisonment. Last week the Pennsylvania Supreme Court disagreed with Nash, arguing that "his certainty is not shared by all commentators and scientists in the field." Unlike fingerprints, the court noted, spectrograms may vary according to such things as the speaker's health or age. And like a lie detector test there is a risk that the jury will give too much weight to such testimony. Though top courts in two states admit voiceprints as evidence, the court decided that Pennsylvania would not join them until there was "general acceptance" of the precision of voiceprints among experts. The court then...
...overdone roast can set it off. Easy to install, the bowl-shaped sensors can be simply plugged into house current. Even better, some are powered by batteries; these generally last a year and chirp insistently when they are running down. Smoke sleuths can be used in conjunction with heat detectors (cost: $100 plus for a complete system). Heat detectors are slower to sound a smoke alarm and are used mainly in closed areas such as basements and garages, where a quick heat buildup is likely. Says Fire Marshall Rex Jordon of Olympia, Wash.: "Heat 36 detectors are fine...
...federally sponsored study of the "chance of escape after alarm" in several deliberately ignited homes showed that one heat sensor in every room provided only an 11% escape potential, while one smoke detector at each level of the house gave an 89% chance of escape. Many states and cities now require smoke detectors in all houses and apartments before they are sold or resold. The Federal Government will not approve a VA or FHA new housing loan unless the structure has detectors; Montgomery County, Md., will require all homes to be equipped with the sensors by July 1, 1978. Most...
First, the sleep clinicians probe deeply into a patient's sleep habits−for example, by questioning his bed partner. They also video-tape his slumber behavior in special sleeping rooms, where patients spend the night hooked up to a polygraph, a lie-detector-like machine that monitors sleep-related physiological functions (breathing, muscle twitching, rapid eye movement...
