Car Safety: How Airbag Work
Sunday, January 21st, 2007When airbags first became available in vehicles in the 1980s, they had the same dubious reputation as the first seatbelts. Consumers feared that they would cause more harm than good, exaggerating their potential to harm and even kill drivers and passengers. Although these accidents occurred on occasion and still do, though less frequently, the life-saving potential of airbags cannot be disputed. In fact, deaths from front-end collisions are decreased by thirty percent in automobiles with airbags. Better yet, as airbag technology improves, front and rear seat passengers are also more protected. The following provides a brief history of the airbag as well as an explanation of how it works.
The history of airbags began in World War II, when they were first implemented to provide protection during airplane crash landings. Although they had little in common with the modern airbag, these inflatable devices were designed to deploy to limit the amount of damage done to pilots. Decades later, the US government saw their potential in commercial vehicles. Although they found that the introduction of seatbelts provided increased safety, the impact of front-end collisions still often seriously injured or killed passengers. For this reason, they turned their attention to the crude airbags of previous decades. When a car hits an object head-on, it immediately stops. However, any objects that are unrestrained in the vehicle continue to move, including people. This is because they maintain momentum from the moving vehicle, even after it ceases to move. When a body is thrust forward, the impact of hitting a steering column or dashboard can be deadly. (more…)
The S.W.A.T. Auto Alarm is a steering wheel anti-theft alarm with a remote. It is activated by opening a door, breaking a window or even a sharp jolt to the vehicle. It features a flashing strobe light that will light up the inside of the vehicle. When armed, LEDs flash out a warning. Should a thief break a window or open a door, a strobe light flashes, ‘night blinding’ the intruder, and a 130 dB alarm goes off.
People who have Bulldog Security 802 are usually buying it for economic reasons. It sounds not as loud as more expensive alarms. For the cheap price, some consumers are experiencing a few false alarms. 
It had keyless entry and several alarm tones that you could set. The keyless entry is great if your hands are full and you don’t want to put everything down to get the door unlocked. Not to mention that if by some chance you are running for your life from a mad man that you can hit the keyless entry on your way screaming toy our car.
