After originally filing for a patent in Singapore in May 2020 and then later in the United States in November 2021, Apple has received its drone controller connectivity patent from the United States Patent and Trademark Office yesterday.
The patent covers systems for pairing/unpairing unmanned aerial vehicles (UAVs) to/from UAV controllers (UACs) while also also involving tech used to switch signals connecting a drone from direct transmission from the controller to cellular networks when distances become too great to maintain contact, or UAVs enter obstacle-heavy areas where blockage becomes a problem.
Patently Apple has showcased an example of the UAS (unmanned ariel systems) in Apple's patent in figures 9 & 13 below.
