Abstract: A ball sports training system has a processor(s) and a memory storing program instructions that, when executed by the processor(s), causes the one or more processors to: cause a ball passing system to move between a first position and a second position different from the first position; (b) determine when the ball passing system is in the second position; and (c) responsive to the determining, cause the ball collection station to release the at least one of the first plurality of sports balls, whereby the at least one of the first plurality of sports balls is moved on a delivery travel path. The second position is selected to position the second receiving portion in the delivery travel path of the at least one of the first plurality of sports balls, whereby the second receiving portion is configured to receive the at least one of the first plurality of sports balls.

Abstract: An air bag on a surface is gathered by opposing faces of first and second gathering elements that are moved together from opposing edges of the air bag, and which are adapted so as to limit a height of at least one associated edge portion of the air bag to be less than a height proximate to a center of the resulting gathered air bag. In one aspect, a surface is extended from at least one face, or at least one face is shaped so as to limit the edge portion height upon gathering. In another aspect, at least one gathering element incorporates a holder adapted to hold an edge of the air bag during gathering.

Abstract: An airbag assembly includes a module with a base plate, an airbag, and a housing for the airbag; and a cover removably attached to the module.
