Apple has a knack of filing patents and bagging them even when it has no intents of using a technology in the near future. In fact, many Apple patents don’t see the light of the day and remain just patents. Nonetheless, this can be deemed the company’s strategy to guard its intellectual property rights.
Apple had filed a patent relating to the methods, circuits and apparatus for adapters. The general description of the adapters seem to indicate that the patent is about cable adapters and inserts.
The patent also speaks about docking stations which will make use of reradiating antennas which will help reaffirm the strength of a signal as well as inductive charging circuits. Moreover, these docking stations may also make use of optical data links.
However, so far Apple hasn’t released any inductive charging dock for its iOS devices, although a number of other handset vendors are jumping this bandwagon. The dock is set to receive a device in upright as well as other positions.
The dock is configured so that it is also able to charge the battery of a device through an inductive charge coupling mechanism. According to the patent filed, the inventors of this patent are named as Stephen Zadesky, John Tang and Victor Tiscareno. The patent was originally filed as back a s 2008.
