ABCs of Car Tech: Safety tech

You have heard gear heads brag about their car's horsepower, handling, and modifications, but when was the last time you've heard anyone brag about their new whip's crash-worthiness?

This week, we'll be taking a look at the unsung heroes of the automotive industry. Some of this hardware could save your life in the event of a crash, while other elements are there to keep you from dinging up your paint job in the first place. That's right. This week, I'll be explaining passenger safety tech.

Seat belts and SRS: Supplemental restraint system

Seat belts are the oldest bit of passenger safety tech and are basically fabric straps that keep you from bouncing around the cabin in the event of an accident. In the earliest days of motoring, you got a two-point lap belt and padded dashboard, but in the 80s, we saw widespread use of three-point safety belts for all passengers.

Working in tandem with the modern seat-belt system is the "supplemental restraint system," which is basically a technical term for airbags. In the beginning, only the front passengers got airbags--usually located in the steering wheel and dashboard. Modern airbags are triggered by sensors in the car that measure vehicle deceleration. When a car runs into something, it decelerates at a terrific rate, triggering the system's deployment. Gasses from a small chemical explosion are captured by the nylon fabric airbag, creating a cushion of air in as little as 8/100ths of a second. I can tell you from experience that the airbag slap stings, but it's definitely softer than the steering wheel.… Read more

New cars get safety feature that can help prevent fatalities (video)

A certain safety feature in cars could cut the number of fatalities in single-vehicle accidents by almost half and by 20 percent in multi-car crashes, studies have shown.

Car crashes cost $300 billion a year, according to a recent AAA study, and the human cost is even greater. Consumer Reports says a technology known as electronic stability control can dramatically lower the number of deaths in car accidents. Not all vehicles are equipped with the safety feature; in the past, it was often offered as an upgrade. But starting with the 2012 model year, all cars must come with ESC. … Read more

Ford debuts Curve Control on 2011 Explorer

Ford's upcoming 2011 Explorer SUV will feature the industry's first inflatable rear seat belt, but that's not the only new technology that will be debuted with the new model. Curve Control is a driver aid system that is designed to help a driver to maintain control of a vehicle when entering a curve--such as a freeway off-ramp--with too much speed. Wait. How, exactly, is that different from regular stability control?

Here's how the new system works: as the vehicle enters a turn, Curve Control measures the driver's steering input and the speed of that input. … Read more

Gibson's Robot Guitar--exposed!

SAN JOSE, Calif.--For the gathering of curious onlookers eager to see what a Sony OLED TV looks like on the inside, officials at the Embedded Systems Conference had some bad news: The airline (no, they didn't say which one) lost their stuff. Unfortunately, their stuff included that TV.

Instead, as a last-minute replacement, we got Gibson's Robot guitar, which was scheduled for the teardown treatment later this week. (See our earlier coverage of the Robot guitar here and video of it in action.)
