It uses the familiar UAV for "unmanned aerial vehicles" and introduces AFC for "aerial fulfillment center."
They have visions of the AFCs not only being placed above metropolitan areas where people can simply browse the inventories of them, but actually moving into place in on demand scenarios:
"An AFC may navigate to an area based on various positioning factors. For example, a temporal event (e.g., a football game) may be expected to produce a demand for certain types of items (e.g., sporting paraphernalia, food products, etc.). In advance of the event, the items may be delivered to the AFC in a quantity sufficient to satisfy the expected demand and the AFC may navigate to a position such that UAVs deployed from the AFC can safely navigate to the location of the event and deliver the items, thereby satisfying the demand. In some implementations, the AFC may navigate to a lower altitude and provide advertising for the temporal event or for other occasions (e.g., product announcements, product releases, sales)."
Very reminiscent of carriers from StarCraft slowly lumbering into position and releasing robotic fleets from their bowels.
But they don't stop at just advertising for these "temporal events." Bringing up visions of the omnipresent geisha blimp from Blade Runner, they describe ways in which ads can be displayed around 2,000 feet in the air above cities as well.
There's language like "docking bays" and "dirigibles" in a world with shuttles going to and from AFCs, charging and repairing UAVs autonomously.
The patent is a long read, as patents tend to be, but definitely fun if you're into this sort of stuff.
