US Patent 11835949 Autonomous device safety system

An example system includes a positioning surveillance system (PSS) to identify locations of objects that are movable throughout a space. The PSS is configured to identify the locations without requiring a line-of-sight between the objects. A control system is configured to determine distances based on the locations of the objects in the space and to communicate information to the objects that is based on the distances. The information is usable by the objects for collision avoidance.
