Tesla is constantly updated for your vehicles. One of its innovations that have surprised the world are the laser wipers, They look like something out of a futuristic movie.
As heard, the company Elon Musk uses a laser that is capable of cleaning glass surfaces that replace the brushes that are currently used.
In addition to being used on the front and rear glass surface of electric vehicles, it could be used to clean the optics of the cameras of ADAS systems, thus keeping the surface always clear.
It should be remembered that in 2019 he applied for a patent that was granted two years later by the US Government Patent Office.to register an invention that eliminates traditional windshield wipers from their cars and replaces them with a laser system.
The laser wiper system consists of three basic parts. Sensors that detect dirt on the glass, laser emitters that, with a certain intensity, they must eliminate it and an electronic control system that regulates the functioning of both parties.
The sensors would be placed on the hoodslightly further away than current conventional windshield wiper water sprays and they would act by directing a beam of laser light towards the windshield in a similar way to the well-known “skunks”. But there is an intermediate step that is vitally important. So that the laser does not hurt or affect passengers of the car, the glass must have a indium tin oxide coatingwhich would fulfill the function of “protective shield”.
indium oxide It is a chemical compound with multiple applications, especially in the electronics, for being a magnetic Superconductor, that when combined with tin dioxide, acquires the character of a transparent electrical conductor. It is often used in LCD screens, smartphones and solar panels due to its properties.
In addition to the laser sensors placed on the hood, Tesla’s patent blueprints show other sensors at b-pillar, between the gates, and on the fendersand it is speculated that they could also be attached as way to keep the cameras clean too of the cars produced in California, which by the way are varied, by the autopilot system autonomous driving.
beyond the essential advantage of better glass cleaning front and eventually the other glass surfaces of a car, remove wipers is a way to contribute clean the environmentbecause they will be removing metal parts, rubber and plastic, but the water deposits for the windscreen wiper function will also be eliminated, with which the contribution to the less water consumptionIt is a contribution of great value.
Previously Volkswagen AG also announced that it will eliminate manual gearboxesa measure that will also contribute to the production of fewer metal and rubber parts, by removing from production a third pedal and the entire system of rods and forks that acted for the driver to change gears manually.
Finally, the absence of a wiper blade will allow for longer life and quality of visibility through the windshields, because there will be no friction element that wear or damage them with the dirt adhered to the glass and because there will be no defects from a low quality cleaning due to a worn brush or with dirt on its rubber band that drags on the glass surface. What’s more, the laser will reach every corner of the windshieldand it won’t leave that section that the wiper blades never clean, naturally reducing the driver’s visibility.
