Why Won’t Amazon’s Drone Tether Swing?

The video of Amazon landing a delivery drone on a happy father’s front lawn has made the rounds, but Amazon is hedging its technology footprint and pursuing tether delivery by drone as well. This patent application is about the flawless final step of delivery, dropping the item at its destination. Apparently, it’s not as easy as it sounds.

Amazon Quells Drone Noise with Anti-Noise

Phase cancellation is an interesting acoustic phenomenon. If two identical signals are 180 degrees out of phase, they will completely cancel each other out. With the eventual proliferation of delivery drones, noise will be an issue. As Amazon puts it, “the net effect of the noises generated by the unmanned aerial vehicle may be annoying at best, or deafening at worst.”   Behold: the Silent Drone. Amazon has presented a patent application “directed to actively […]

Virtual Fences for Drones, Among Other Advantages

On a quest to find drone geofencing, this interesting invention appeared. Essentially, the application describes a database of property lines. The database would make it possible to assign certain permissions to users for various uses (mineral rights, etc.) of real estate. The virtual fencing would come with the real estate’s title, and would give the rights-owner legal permission to tell someone to get off their lawn. What does this have to do with drones, you […]

Amazon’s Narrow Patent Application for Drone Delivery

It’s been the talk of the town since Amazon ‘leaked’ its drone-delivery service, but in reading the patent application for this invention, there is plenty of room to maneuver around Amazon. The application is well-written as far as understanding the concept of drone delivery: “The final, or last mile delivery of physical items to a user specified location is traditionally accomplished using a human controlled truck, bicycle, cart, etc. For example, a user may order […]

Drones Navigate RFID Highway

As more and more UAVs clutter the sky, navigation becomes a real issue. Delivery by drone sparks some of these questions: how do you prevent collisions? Optimize efficiency? Keep track of inventory? Certainly, GPS-borne navigation is the flavor du jour, but it’s not the only nav protocol. Along comes Azure Sky Group LLC, and their patent application for radio frequency identification (RFID) method. RFID is nothing new, and most new credit cards have a chip that works on RFID. […]
