The basic wiper blades design has undergone a variety of changes since it was designed at the beginning of the twentieth century. At the beginning it was just a pair of brushes wiping down a horizontal sheet of glass and now they come in all shapes and sizes such as the flat wiper blades and the silicone wiper blades. Even the numerous different types come with a category of modes and options in regard to the speed at which they run.
These sorts of wiper blades are often called intermittent wiper blade and can be set to a variety of speed settings to suit the prevailing weather conditions.

These days you can even cut out the human completely and just have rain sensing science installed. We are truly living in an enlightened age where technology has become so pervasive that we routinely take it for granted. In fact it is a testament to the excellence of these technological marvels that we take so little time to even notice them, simply forming a subtle backdrop to the delicate fabric of our lives. This is the era of computing and rain sensing technology is no different it utilises a computer to calculate the amount of rainfall and how fast the replacement wiper blades should respond. One day computers will become so pervasive in our society they may even be sewn into out clothing or even surgically placed into our own bodies. Just like the replacement wiper blades designed by a single lone inventor using her individual craftmanship to oil the engine of progress, the computer has been the brain child of a few acclaimed scientists, Charles Babbage for one, he was the first to engineer a mechanical calculating device. Another inventor of note is John von Neumann who was the start of all contempory personal computers converting theory into the hardware which drives all modern day digital computers. Like other sciences the replacement wiper blades has its own pantheon of designers who are liable for its great impact upon the world. People like Mary Anderson who was the designer of the first functioning replacement wiper blades device and Robert Kearns who made intermittent windscreen wipers technology.

While not quite as revolutionary as the modern computing age, the wipers has still made a massive impact on the world in a more subtle manner. Most people agree that the number one cause of accidents on the roads is caused by having bad visibility. Now the only real way to remedy this situation as best as possible giving the present atmospheric conditions is to use good wipers. In fact, although often ignored as an after thought the modern day wipers is no doubt responsible for saving many lives around the world and since the wipers is as old as the motorcar, these probably number in the millions. The first large technological jump in wipers design harks back to Robert Kearns who having lost his sight after getting a champignon cork lodged in his socket on his own wedding day, found the wipers motion quite harassing and sought a way to make it more changeable.
