Other products are even more portable and flexible. Intoximeters Inc. of St. Louis produces the transistor radio-size Alco-Sensor, which is being used for roadside tests by police in cities like New York. The $390 device gives a digital readout when the suspect breathes into its plastic mouthpiece. In July, Allstate Distributors of Marietta, Ga., introduced a coin-operated tester for use in taverns...
...smoke-alarm klaxon, which briefly startled the crew. Because a fire or any outpouring of gas in Challenger's confined atmosphere would have lethal potential, the shuttle has seven fire extinguishers primed for instant use. However, a quick check showed that the alarm was set off by a sensor in the cargo area's aft bay No. 1 that had a history of being supersensitive, like a home smoke detector that goes off at the merest cigarette puff. Other sensors on Challenger's control panel were normal, and so, with the approval of flight engineers, the crew...
...York City's Columbia-Presbyterian Center for Stress and Pain-Related Disorders, Dr. Kenneth Greenspan claims to be able to reduce the severity and frequency of migraines in 80% of sufferers. The principal weapon: biofeedback. The patient is connected by sensor wires to a machine with a small screen that feeds back information on such physiological indexes of stress as blood pressure, tension in the facial muscles or, most frequently, the temperature of one's fingers - the colder, the tenser. By loosening their muscles, breathing deeply or letting their thoughts drift, patients learn that they can control their...
...Millionaire Nolan Bushnell, 40, forsees an almost boundless future for the $2,500 machine. Concerned about crime in your neighborhood? Not to worry, "Home security," says Bushnell, "is just moments away." With the proper software, he claims, BOB could patrol a house and call the police when its heat sensor sniffs an intruder. When BOB isn't watching the house, he could be cleaning it. "As soon as we get an arm on him, vacuuming will be easy," says Bushnell. Eventually, he hopes, "BOB will be programmed to fetch things-get the paper, pick up after its master...
...panel traced the troubles with the fan in Allen's suit to the seepage of moisture (probably from breath and perspiration) into a tiny control device. No larger than two pinheads, the sensor regulates the electrical pulses to the fan's motor. Although the investigators still have not found out why water should have penetrated the device's epoxy covering, they have made clear that its porosity should have been uncovered long before the $2.3 million suits ever went into orbit. There was, however, no doubt what went wrong with Lenoir's suit. Despite all efforts...
