A lane divider system includes a guide rail and a lane divider bracket for connecting the guide rail to the loading and unloading ends of a flow bed. The guide rail can be tubular, with a proximal end of the bracket inserted into each end of the tube. Retention devices for releasably securing the distal ends of brackets to the loading and unloading ends of the flow bed can include a pin, inserted through an opening in the distal end of the bracket, beneath where the bracket is inserted through the flow bed. Preferred pins can include a handle portion for inserting and pulling the pin out of the opening in the locking structure, such as a split cotter pin, resilient projection, spring clip and the like, to resist the unintentional withdrawal of the pin from the end of the lane divider.

A conveyor system includes a drive assembly and a plurality of rollers configured to singulate a plurality of conveyed articles travelling on the plurality of rollers along a direction of travel. Each of the plurality of rollers having a drive end and a base end. The drive end having a drive sheave including a plurality of grooves and a plurality of peaks interposed between the plurality of grooves formed on a surface thereof. The drive assembly is coupled to the drive end of at least one of the plurality of rollers by a drive belt. At least a first portion of the plurality of rollers is disposed at an angle with respect to the direction of travel.

An energy harvesting roller for a cargo handling system may comprise a shaft and a sleeve located on the shaft. A piezoelectric member may be coupled to the sleeve. A shell may be located radially outward of the piezoelectric member and configured to rotate relative to the sleeve. A radially inward surface of the shell may define at least one of a plurality of grooves or a plurality of protrusions.

A drone comprises at least one propeller for generating lift and an article containment area for containing an article to be carried by the drone. The floor of the article containment area comprises a dynamic support surface for supporting the article and allowing the article to move into, out of and through the article containment area. The dynamic support surface may be a conveyor belt forming the floor of the article containment area.
