title: Vehicle safety technology text: road accidents. The initial safety features were the safety glass, four-wheel hydraulic brakes, seat belts, and padded dashboards. A scientific approach to vehicle safety began in 1934 when General Motors conducted the first crash barrier test. Gradually, the existing systems were stabilized followed by introduction of disc brakes and anti-lock braking system. Introduction of hi-tech safety systems began in the year 1995 with Electronic Stability Control (ESC). The lane departure warning system was introduced in the year 1999 and the radar assisted adaptive cruise control was introduced in 2005. Theses advanced hi-tech systems are not standard parts in all cars. title: Collision avoidance system text: AEB has three characteristics: Early warning systems were attempted as early as the late 1950s. An example is Cadillac, which developed a prototype vehicle named the Cadillac Cyclone which used the new radar technology to detect objects in front of the car with the radar sensors mounted inside "nose cones". It was deemed too costly to manufacture. The first modern forward collision avoidance system was demonstrated in 1995 by a team of scientists and engineers at Hughes Research Laboratories in Malibu, California. The project was funded by Delco Electronics, and was led by HRL physicist Ross D. Olney. The technology title: Cruise control text: "Auto-pilot") using a speed dial on the dashboard. This system calculated ground speed based on driveshaft rotations off the rotating speedometer-cable, and used a bi-directional screw-drive electric motor to vary throttle position as needed. A 1955 U.S. Patent for a "Constant Speed Regulator" was filed in 1950 by M-Sgt Frank J. Riley. He installed his invention, which he conceived while driving on the Pennsylvania Turnpike, on his own car in 1948. Despite this patent, the inventor, Riley, and the subsequent patent holders were not able to collect royalties for any of the inventions using cruise control. In 1965, American Motors title: Timeline of United States inventions (1890–1945) text: candy bar with microwaves. The first food to be deliberately cooked with microwaves was popcorn, and the second was an egg. In 1947, Raytheon under Percy Spencer demonstrated the world's first microwave oven built at the company which was called the "Radarange". 1945 Cruise control Cruise control automatically controls the rate of motion of a motor vehicle. The driver sets the speed and the system will take over the throttle of the car to maintain the same speed. Cruise control was invented in 1945 by a blind inventor and mechanical engineer named Ralph Teetor. His idea was born out of title: Automotive lighting text: lighting. The Ford Model T used carbide lamps for headlamps and oil lamps for tail lamps. It did not have all-electric lighting as a standard feature until several years after introduction. Dynamos for automobile headlamps were first fitted around 1908 and became commonplace in 1920s automobiles. Silent film star Florence Lawrence is often credited with designing the first "auto signaling arm", a predecessor to the modern turn signal, along with the first mechanical brake signal. She did not patent these inventions, however, and as a result she received no credit for—or profit from—either one. Tail lamps and brake lamps were
