Over time, Apple has made its portable products more resistant to water (and dust). Despite everything, it was not until the iPhone 7 and the iPhone 7 Plus to have the first device certified IP67, then a bit above with the iPhone XS certified in IP68. A level of performance certainly renewed on the iPhone XI of the re-entry.
Fewer holes, fewer worries on iPhone
When you think about it, the easiest way to limit water damage is to limit the holes and other holes. Apple had removed the Home button on the iPhone 7 – by putting a touch zone – but did not resolve the case of the speakers, let alone the Lightning port.
The Lightning port offers two functions: it can be used to recharge the iPhone battery and offer a data connection connected to a Mac, PC or accessory. From the iPhone X, you can inductively recharge your phone. But on the other hand, a good number of accessories absolutely require a socket. Apple has started cutting the cord with AirPods for example, but not all third-party manufacturers are there.
In a new patent application filed with the United States patent and trademark office and identified by AppleInsider, Apple's "conductive coating for waveguides" could allow data to be transferred without a physical port.
A waveguide is a structure intended to channel electromagnetic waves along a trajectory, in particular for those which are generally not able to cross the atmosphere effectively, such as millimeter waves. By containing and guiding the millimeter waves, this can allow data transfers which pass tens or hundreds of gigahertz, higher rates than those generally possible with conductive wires.
For the waveguides to function properly, they must be positioned to match the orientation of their transmission and aligned to properly transmit the data to the receiving device.
To solve this problem, Apple suggests that the waveguide can be created from a core made of a solid dilectric material capable of conducting radio waves, surrounded by a sheath comprising conductive parts that can allow the transmission of signals. electric.
By using the conductive parts to determine how one end of the waveguide is fixed, the other end can change the way it transmits through the waveguide. Although it may be simple for a rectangular waveguide cable, it also means that the system would work effectively for a circular cable, which could have many segmented areas for transmission and conductive parts.
To facilitate alignment, magnets could also be used to hold the cable in place and to ensure that it is correctly placed by the user in the first place.
Every week, Apple files a patent application covering a wide variety of fields. However, while repositories indicate areas of interest to Apple, this does not guarantee that the features will appear in a future product or service.
As a reminder, Apple filed another patent last year on the sealing of the Lightning connector based on rubber rings serving as a seal, deformable sheaths, conical connectors and even a vacuum generator.
