Apple files patent to automatically block oncoming high beams

#AccheDin for our children when this technology trickles down to Bharat in another decade?
Apple was awarded patent 11,130,391 for "Active glare suppression system" on 28th Sep

Here's what a gentleman Ajay Kumar just posted on LinkedIN (yes, sometimes LinkedIN serves useful stuff, LOL).

If you like this post, don't thank my post, click the above link and like it on LinkedIN for him to see!

I am merely re-sharing it here - it is entirely his explanation for this patent and photos from this page.

Quote:
Why, he is not lowering the headlights?

I am sure that you generally say this while driving at night.

Because the sharp lights (direct into the eyes) from upcoming vehicles can make us blind for a while.

Isn’t it a serious issue, every time you have to lower your headlamps. Even if someone doesn’t, it also causes problem to others. It makes driving tougher at nights.

Well, Apple came up with a solution for this problem. (Wait, is this for Apple car ?) Three days back, Apple granted the patent 11,130,391 on this. Let me explain you in detail-

This latest patent win covers a next-gen system designed to block blinding sunlight or nearby vehicle lights from distracting a driver. This next-gen safety feature will darken areas of a vehicle's windows and mirrors to block blinding light and could one-day replace the traditional yet archaic sun visor system.

The solution includes a control circuit, may gather eye location information indicating where the eyes of the driver are located (using a sensor such as a camera mounted in the vehicle). It may also gather information on where an external object that produces glare (such as the sun, a street lamp, a reflective portion or headlight of a vehicle). Based on this information, the control circuit may direct a light modulator on a window or vehicle mirror to selectively darken an area that prevents the glare from reaching the eyes of the driver.

The camera system (camera) 28 of FIG. 6 may be used to perform triangulation operations that help control circuitry accurately determine the location of driver 92, the driver's eyes (eyes 64), and the direction of view of the driver (direction of view 94 in the example of FIG. 6). FIG. 5 is a flow chart of illustrative steps involved in using a light modulator to reduce glare in a vehicle.

The light modulator may be patterned to form a series of strips, rectangular regions, or areas of other shapes that extend along the upper edge of the front window of a vehicle and that therefore allow the light modulator to serve as an electrically adjustable sun shade. The light modulator for a window or vehicle mirror may have a photochromic layer that is adjusted by shining light onto the photochromic layer, may be a liquid crystal modulator, may be an electro chromic modulator, or may be formed using other types of light modulator structures.

FIG. 7 below is a perspective view of an illustrative window with multiple locally darkened portions to reduce glare, and in FIG. 8 we see a single darkened portion to reduce glare.

Isn’t it an awesome innovation ? Apple never fails to amaze us (have you heard about the macro photography feature of iPhone 13 pro?).

My simple solution to this is to use anti-glare eyeglasses with a mild tint that your own cars headlights easily overcome for clear visibility. Cost-effective and cheaper!
