A new patent from Apple suggests that the windshield of a future Apple car may have a groove for sensors. &Apple cars will have a number of sensors built in to allow it to drive automatically, and some of them need a window or groove to allow them to work through plastic or fiberglass in the car body. < / P > < p > Apple’s patent is called & quot; sensor housing and sensor housing Glass & quot;, which includes how to install many of the sensors needed for autonomous driving, and apple describes how to best secure and expose sensors to make them work. Apple had previously created a fringe on the iPhone so that face ID could work properly. < / P > < p > Apple does not use the word gap in the patent text, nor does it mention face ID. However, apple described how to make holes in the car body to install the sensor. Apple said the installation of an optical grade toughened glass panel through the opening formed by the exterior body panel provides an open interface. At the same time, part of the car chassis can contain the sensor array installed, in addition, it can also install sensors in the car bumper, but Apple still has the same problem to solve, that is, to make the sensor work and to be protected. < / P > < p > Apple said in its patent that sensors can include lidar sensors, infrared emitters, visible cameras, infrared cameras, etc., some of which cannot tolerate the signal attenuation that may occur when transmitting and / or receiving signals through glass, plastic or other transmission materials. However, there is an alternative that protects the sensor but allows the signal to pass through. Optical grade glass with controllable refraction can be used in sensor applications to avoid signal attenuation. Options for this optical grade glass include n-bk7 by Schott AG, s-bsl7 by Ohara corporation or h-k9l by cdgm Glass Company Ltd. < / P > < p > the patent drawing shows that the glass is positioned in the front of the & quot; Apple car, but the drawing is not drawn to scale, so it is not possible to determine how large such a sensor gap is.
