American schoolgirl came up with a way to get rid of the “blind” areas in carsNovember 4, 2019
A 14-year-old child proposed a special projector that is able to broadcast the image of the space around the car to those elements of the car that create these very “blind” zones.
The safety of modern cars can reach a new level. And it all started with the fact that 14-year-old American Alaina Gassler decided to participate in a competition in mathematics, applied sciences and engineering. The girl devoted her project to the elimination of blind spots in cars. About it writes “Mashable”. Looking ahead, let’s say that Alaina’s work was recognized as the best, and the schoolgirl herself received a cash prize of $ 25,000 for her. So what surprised the adolescent strict jury?
The girl created a prototype system on a 3D printer, which included a webcam and a projector that broadcasts a picture from the street to the front desk of the car. It is she who very often closes the review to the driver. The result was a kind of “transparent” racks. The solution to the problem of “blind” zones turned out to be elegant and simple, like all ingenious.
The webcam is installed at the base of the front car rack, and video from it in real time thanks to the projector is shown on the inside of the rack. The projector is mounted above the driver’s seat.
The hardest part in this work, according to the schoolgirl, is to make a lens that could focus the image on an object located at such a short distance. To make the picture clearer, the rack was “draped” with a special fabric that reflects light only towards its source: the driver and the projector above it. Thanks to this, the driver sees a clear picture, and passengers see only the fabric.
