Using unmanned aerial vehicles, Amazon Prime Air proposes to deliver packages to customers within 30 minutes or earlier, and Amazon Inc., filed a patent application in India for exclusive rights on multi-scale fiducials to be used on its drones to identify them from different distances.
Business Standard reports that these fiducials will have three or more scales, where the child fiducials are nested or linked by a relative position to the parent fiducials, facilitating target identification and tracking. Another application may be focused solely on an innovation that will enable target identification of other drones or similar aerial vehicles. Earlier, Amazon Technologies had filed a patent application in India for a technology that would ensure a quick response from the propellers of a drone in case it detects an object like a human or an animal in its path.
Amazon will expand its drone operations once it establishes the safety and reliability of these systems.
