Abstract: A launcher device includes a hopper having an open end disposed beneath a stack of UAVs. A retainer retains the UAVs in the hopper and releases one of the UAVs at the hopper's open end. A movable carriage disposed beneath the retainer receives the released UAV. The carriage is operable to be moved along a first direction from beneath the retainer to a terminus and subsequently operable to be moved along a second direction from the terminus to beneath the retainer. When moved in the first direction when the released UAV is on the carriage, the carriage moves the released UAV in the first direction to the terminus. A ramp aligned with the carriage guides the carriage along the ramp as the carriage is moved along the first and second directions.

Abstract: A mine roller includes a bracket having a first end and a second end. The first end is adapted to be coupled to a vehicle. A rigid table has a center section and modular sections with the center section being coupled to the second end of the bracket for rotation about the second end in a first plane. The modular sections are coupled to the center section for rotation therewith. Roller banks are coupled to two of the modular sections for rotation relative thereto in a second plane that is perpendicular to the first plane.

Abstract: A mine roller includes a bracket having a first end and a second end. The first end is adapted to be coupled to a vehicle. A table having a center region is coupled to the second end of the bracket for rotation about the second end in a first plane. The table has first and second telescopic portions coupled to the center region such that the table is extendable relative to the center region in opposing directions of a second plane that is perpendicular to the first plane. A roller bank is coupled to each telescopic portion of the table for rotation relative to the respective telescopic portion in a third plane that is parallel to the second plane.
