Autonomous refill station for docking-based fluid transfer in security robots

PendingUS20260116351A1Chemical warfare equipmentSpraying vehiclesThermal monitoringSimulation
An autonomous refilling system for a mobile security robot is disclosed. The system includes a refill station having a fluid reservoir, a pumping mechanism, and a docking interface configured to align with a refill port on the robot. A sensor system verifies docking, while a fluid level sensor on the robot monitors onboard reservoir levels. A control module initiates and terminates fluid transfer based on docking status and fluid conditions. In various embodiments, the station incorporates redundant sealing, leak detection, thermal monitoring, and multi-reservoir support for different fluids such as water, invisible ink, or scent-based deterrents. The system may be integrated with a centralized management platform that coordinates refilling across multiple robots and stations.

Additive printing process for a substrate using invisible fluorescent inks

The invention relates to a method for printing an image on a security document, said method using invisible inks that are fluorescent and visible under ultraviolet light, characterized in that it comprises an additive color synthesis step, consisting of: decomposing a visible digital image into three digital image masks Red, Green, and Blue (R, G, B) such that the superposition of the three masks corresponds to the base image; applying to each digital color mask R, G, B a computer processing consisting of introducing security patterns into each of the digital masks R, G, B; printing these three Red, Green, and Blue masks one on top of the other on a physical substrate (paper, polycarbonate), using luminescent invisible inks so as to form on the substrate an invisible image containing the security patterns previously introduced into the three RGB digital masks.
