For example, Apple has announced a high-profile,iPhoneThe 7 and iPhone 7 Plus are the first products with IP67 waterproof and dustproof capabilities. The iPhone XS's waterproof capability has been upgraded to IP68, and the new iPhone, which is expected to be released this year, will remain at this level.
While Apple is developing new ways to stop water and dust from entering its mobile devices, the easiest way is to reduce the number of entry points, which means sealing the body by removing ports and other openings. In addition to the holes required for speakers and microphones, the iPhone is also equipped with a Lightning port.
The Lightning port has two main functions, which can be used to charge the iPhone, or to connect to a computer to transfer data. In terms of charging, wireless charging can be used instead. However, physical data connections are not easily replaced, so it is difficult to completely remove the port.
But according to Apple's patent application filed today, the new technology may pave the way for future iPhones to cancel the Lightning interface, which means data transmission without physical ports.
In the patent application, Apple discloses a waveguide structure that allows the device to determine its orientation. The waveguide may be formed of a dielectric core and a cladding, and the dielectric core may be formed of a solid dielectric material that conducts radio waves at a frequency of a millimeter wave frequency or more. By directing millimeter waves, data can be transmitted at a higher rate than the transmission rate at which conductive wires are typically used.
In order for the waveguide to function properly, the waveguide must be placed in a position that matches its direction of transmission and aligned to be properly transmitted to the receiving device. In order to solve this problem, Apple suggests that such a waveguide can be fabricated from a core of a solid dielectric material capable of conducting radio waves, surrounded by a cladding layer including a conductive portion that can transmit electrical signals. The conductive portion and the electrical signal are only used to determine the direction of the waveguide to the receiving or transmitting device, rather than the user's large-scale data transmission.
The conductive portion is used to determine how one end of the waveguide is connected, while the other end can change the way it is transmitted through the waveguide. Although this may be simple for a square waveguide cable, it also means that the system can work effectively on a round cable. To facilitate calibration, you can also use a magnet to hold the cable in place and ensure that the user places the cable correctly first.
