I think the Apple car is the device that has been talked about the most and we don't even have an approximation of whether it will be real. Two new patents hint that the Californian company has the ability to include a new technology by which Apple's car could automatically tint the windows.
The Apple car could automatically tint the windows is an idea that is reflected in two patents
Apple's car could automatically tint the windows through an intelligent polarization system. Liquid crystal technology would be used to block sunlight from looking inside the vehicle. This lens darkening technology is very useful. For some drivers it is a question of safety behind the wheel as strong lights are avoided. For others it also means a plus of privacy inside the vehicle.
The patent itself speaks of the use of liquid crystal tint. The record is called "Devices with host-host liquid crystal modulators". The car could have windows with multiple layers, designed to block different types of light. This can be divided into visible and non-visible wavelengths. On the non-visible side, selective filtering could block ultraviolet light and both near and far infrared light.
Apple suggests that a "Light modulator of that liquid crystal". These polymeric substrates could be thermoplastic, moldable to confirm window surfaces and shapes, while the tint could be dichroic or a mixture of tints.
The possibility of a "System and method for dynamic privacy and window tinting". This second patent mentions that conventional tints do not "adequately protect occupants from sunlight and other forms of light" from the exterior of a vehicle, in addition to not providing "adequate privacy." The patent suggests the use of a computing device connected to tinting hardware modules Able to adjust the tinting level on the other, generally by adjusting the voltage level of the adjustable tinting film.
Whenever we talk about patents, it may happen that they do not actually materialize. They can be just ideas. Apple registers many of these ideas a year and not too many are seen in the market. We will remain attentive to these ideas related to the Apple car.
