What the filing covers
A closed-loop UAV landing-safety system that projects directional warnings to detected bystanders, verifies the projection actually emitted, and binds the event to a tamper-evident hash-chain. I filed this because a landing warning needs to reach the people near the drone. The system detects bystanders and projects directional warnings toward them. It then checks that the projection actually emitted. A tamper-evident hash-chain binds the warning event to a record for later review.
Why it matters now
People walking or waiting near a landing area may not know a drone is about to land. A notice to the operator reaches a different person from the bystander at the site. Requesting a projection and confirming its emission are also different events. The warning and its emission record both matter when reviewing activity around a landing.
A real-world example
Imagine a delivery drone approaching an area where a person is waiting. The person is close to the landing activity. A directional projection is aimed toward the detected bystander. The system then checks whether that projection emitted and records the event.
I connect those steps because the warning has a physical purpose. It needs to be directed toward a person at the landing location. The emission check addresses what the warning equipment actually did. That creates a clearer account than a record of a request to project a warning by itself.
Now imagine someone reviewing the landing activity afterward. They want to know about the warning event at the location. The hash-chain makes later changes to the recorded account evident. The record concerns the projection and its emission; the person's response remains a separate part of what happened at the site.
Where it applies
This work applies to drone delivery, UAV operations and facilities that host landings. I focus on the interaction between an approaching drone and people who are already using the space. A landing location is also a place where someone can be walking or waiting for an unrelated reason.
For a facility operator, I would ask how the landing activity reaches the attention of people nearby. I would also ask how the emission of that warning is recorded. Those are connected operational questions.
A bystander-facing projection serves a different purpose from an advisory to a pilot or a protected corridor around a crewed aircraft. Here, the safety interaction happens at the landing site, between the drone's activity and the person near it.
