Abstract: A robotic vehicle can seek markers in one or more zones and take action if the marker so indicates. Systems, methods, and computer-readable media can cause a robotic vehicle to seek and identify a marker, then determine whether action should be taken based on a characteristic of the marker. If an action should be performed, the robotic vehicle can perform an action, and if no action should be performed, a determination can be made whether to seek another marker, move to another zone, or terminate the robotic vehicle's routine.

Abstract: An intelligent traffic control system may be configured to manage autonomous vehicle traffic, such as by communicating with autonomous vehicles. The intelligent traffic control system may be configured to output an indication of a traffic control command to autonomous vehicles and non-autonomous vehicles. The intelligent traffic control system may be configured to determine traffic control commands for autonomous vehicles and non-autonomous vehicles.

Abstract: A cooling system configured to remove heat from a chimney of a server cabinet. The system includes a first heat exchanger unit in the chimney of the server cabinet. The first heat exchanger has a fluid inlet for receiving a working fluid and a fluid outlet for discharging the working fluid. The first heat exchanger also has an upstream surface receiving waste heat generated by one or more servers and a downstream surface that discharges air cooled by the first heat exchanger. The upstream surface is generally perpendicular to the downstream surface.
