Abstract: A system includes an article supply location, wherein the article supply location includes a plurality of articles to be sorted, first and second transport vehicles, each having a first position in which an article is stowed about the vehicle and a second position in which the article is deposited into a proximal container. And a control system. The control system is configured to receive an order for a plurality of disparate articles, determine one destination container of a plurality of destination containers to direct the transport vehicle to deposit a selected article, direct the first transport vehicle to transport a selected article to the destination container and deposit the article by manipulation of the first transport vehicle from the first position to the second position for deposit of the selected article in the destination container.

Abstract: A multi-pulse propulsion system includes at least one pulse chamber containing at least one propellant for igniting during at least one pulse of the multi-pulse propulsion system, at least one additional pulse chamber containing at least one additional propellant for igniting during at least one additional pulse of the multi-pulse propulsion system, and at least one passive fuzing system configured to initiate the at least one additional pulse. The at least one passive fuzing system includes a sensor and an igniter. The sensor is configured to sense an environmental condition and/or a ballistic condition. The igniter is configured to provide a stimulus that causes ignition of the at least one additional propellant in response to the sensor sensing that the environmental condition and/or the ballistic condition has reached or exceeded one or more threshold values.
