(FORTUNE Magazine) – VEHICLE LOCATOR It's 3 A.M. Do you know where your car is? With the Stolen Vehicle Locator Service you do. Run by PacTel Teletrac, a combined venture of Pacific Telesis and International Teletrac Systems, it can come within 100 feet of tracking your car's precise location. You turn on a hidden paperback-size paging unit when you park. If a thief drives away it sends an emergency signal to receiving antennas around town that triangulate the signal and pass it on to a control center. The folks there help the police retrieve your wheels. An outfit called LoJack runs a similar service in Massachusetts, but can only start searching after you tell them the car is gone. The radiolocation units will cost about $500. Teletrac will also charge a monthly fee of $10 to $15 for consumers, and roughly double that for companies that want to keep track of corporate fleets. Teletrac is testing in Los Angeles and expects to have networks in 41 cities within three years.

COLD-WEATHER CLOTHING Planning a trek to the North Pole? Well, what about that lake up in the woods? Northern Outfitters' Expedition Series clothing can keep you warm and dry for as long as you're out there -- even months -- at frigid sub-zero temperatures. Standard cold-weather gear traps perspiration, and the accumulated moisture eventually starts draining off body heat. In the Expedition duds, a single- layer of polyurethane foam retains the heat while releasing the moisture. Cost: $1,800 for the works, everything from boots and mittens to hats and sleeping bags. Engineer Gil Phillips and his son Jim, the chairman of the Orem, Utah, clothing manufacturer, say users range from Alaskan oil rig workers and film makers to ice fishermen.

ISOSTATION B-200 Here's a back-breaker for employees trying to skip out of work by feigning pain. The B-200, made by Isotechnologies Inc. of Hillsborough, North Carolina, determines the strength and flexibility of the lower back. It is mostly used to help diagnose and treat real back injuries -- but it can also detect the fakers. A patient is strapped into the machine and asked to bend forward and backward, side to side, and twist while a therapist applies different levels of hydraulic resistance. The B-200 can monitor all three planes of movement simultaneously. Test results show up on a computer screen. If an employee is ) injured, his movement is restricted in a consistent manner during each exercise and the therapist can pinpoint a muscular strain or other malady. Someone without an injury, on the other hand, will move haphazardly. Results from the B-200 have been admitted as evidence in worker-compensation cases. Isotechnologies, which has sold some 400 machines to U.S. medical facilities, is now marketing the B-200 to corporations as a device to screen workers before they tote that barge and lift that bale. Cost: $66,900.

HUFFY TRITON Limber up Lamborghini-lovers; here's your kind of bike. Huffy's custom- designed Triton will set serious triathletes or bulging businessmen back $8,000 to $10,000. Each bike is built from scratch by the same gang of technicians that constructs cycles for U.S. Olympians. Customers provide their complete measurements and fill out a detailed morphology -- from their favorite handlebar wrap (leather, cork, or anything else) and wheel preference (disc or spoke) to the terrain they traverse (hilly, flat, rolling). Using the specs, Huffy constructs a mold to determine the precise angle of each carbon-fiber tube. It takes 60 to 90 days to complete a bike. The Dayton company expects to sell just 200 a year, but hopes Triton will cast a halo over everyday Huffys.
