Amazon files patent for deploying exclusive drones in India

As part of its efforts to use drones to handle some of its operations, online marketplace giant Amazon Inc has filed a patent application in India for exclusive rights on multi-scale fiducials, black and white marks on any object for the self-operating aerial vehicles to identify them from different distances. The proposed drones can also be used to identify other such objects, along with aircraft, plying within Indian skies, said the company.

According to the specifications filed with the Indian Patent Office, the multi-scale fiducials will have three or more scales, where the child fiducials are nested or linked by a relative position to the parent fiducials, thereby, facilitating target identification and tracking. Another application may be focused solely on an innovation that would enable target identification of other drones or similar aerial vehicles.
