A Controlled-Harm Explosive Reactive Armor is made of explosive layered between two plates of material with predetermined fragmentation having controlled harm prevention properties. Methods of using a system comprising such supporting architecture provide application designers access to the functionality included in a machine learning solution, but might also provide additional functionality not supported by the machine learning solution itself. In addition, the detection system can be interconnected to surveillance towers scanning detector cases disposed at seaport docks, freight depots and rail terminals for monitoring containers being prepared for shipment or sitting on docks for long periods of time. An operating handle has a U-shape with two legs having teeth thereon for engaging the two sets of gears by moving the handle up and down to turn the gears and pivot the collector between a first position for receiving and collecting the debris and a second position for transferring the debris in the collector to the waste bin.
