Windshield wipers, which have been standard equipment on most vehicles since 1916, were developed to improve visibility during inclement weather. For nearly 100 years, drivers operated the wipers with manual controls mounted on the dashboard. Today, technology has made possible motorized windshield wipers that automatically recognize a developing visibility problem and clear the glass
before the driver can react to the problem.
The term "rain-sensing wipers" is commonly used for a system designed to clear the windshield of rain, snow, and debris without driver intervention. The system is programmed to automatically activate and alter the speed and rate of the wiper blades to keep outward visibility unobstructed at all times. A rain-sensing wiper system does not clean the windshield any better than a manual system; it simply monitors outward visibility and automatically activates the wipers.
How do they work?
The technology behind rain-sensing wipers is not complicated. A small area of the front windshield glass (usually located on the outside of the vehicle, opposite the rear-view mirror) is monitored by an optical sensor. The sensor is designed to project harmless infrared light at the windshield at an angle and then read the amount of light that is reflected back. A clean windshield will reflect nearly all of the light back, while a wet or dirty windshield will cause the light to scatter. The optical sensor can determine the necessary frequency and speed of the windshield wipers by monitoring the amount of light reflected back into the sensor....
