Rain Aware Windscreen Wipers Push Technology Envelope To The Limit.
The everyday wiper blades model has come a long way since its first inception all the way back at the beginning of the century. The initial wiper blades prototype didn’t even have rubber wiper blades it was manufactured from two groups of brushes, these days wiper blades engineering has gone from strength to strength, with designs in both the material used and in the basic design. For example, the normal rubber wiper blades has long since become superfluous and will one day in my opinion be entirely superseded by the mostly superior silicone based wiper blades models.
But that’s not the only thing which has under gone a quantum jump in technology with the start of flat replacement wiper blades assembled to minimise the aerodynamic drag and moving components the world of motor car wind screens has never had it so good. But the action doesn’t end there, now you can even buy replacement wiper blades which dictate their own action with the design of rain operated replacement wiper blades the driver doesn’t even have to push a switch any more. Things sure have come a long way since the driver had to stick his hand out of the wind screen and wipe it down himself, or since the hand crank operated design which required the driver to supply the muscle himself. Recent developements have driven the scientists to come up with rain detecting technology, which will endeavour to adjust the pace of the replacement wiper blades mechanism alone.
The initial attempts at this resulted in wind screens which attempted to detect individual rain drops hitting the wind screen, or by utilizing a specialised paintjob which would prevent water from even laying on the glass. Other techniques have even tried to change vibrations in order to dislodge water from the wind screen cleanly. Ultimately however none of these systems proved effective in the field and they all fell by the way side to be replaced with more effective and more commercially successful designs. The latest incarnation of this technology utilises optical sensors to detect the volume of moisture which is placed easily near the rear view mirror on the inside of the car. Infrared light is projected onto the wind screen at a particular angle, if the glass is clear most of this light will be reflected back, if not the light will be reflected in all aberrant directions triggering the wipers. The wipers are activated by sophisticated software which can determine how much water is on the wind screen by how much the infrared light has been dispersed. The software will then in turn activate the wipers to right speed settings and voila automatic rain sensing wipers are a reality. If the user decides to do it the old fashioned way if he is just plain old school or something he can avoid the system and do it old fashioned way, this also comes in very handy when you’re cleansing the wind screen. This science is currently mainly available in the United States of America but in this reviewers opinion it wont be long be fore it makes the trip across the Atlantic and into European cars.
