  • Patent number: 11142319
    Abstract: A tool includes a handle, an extension member extending from the handle, and an anchor assembly coupled to the extension member opposite the handle. The anchor assembly is configured for selective anchoring to a seat track of an air cargo pallet, and the anchor assembly includes at least one locking member that is movable between an unlocked position and a locked position. In particular, when the at least one locking member is in the unlocked position, the at least one locking member is configured to advance into a slot of the seat track. When the at least one tool is in the locked position, the at least one locking member is configured to mechanically interfere with at least a portion of the seat track in a manner retaining the at least one locking member in the slot, thereby anchoring the anchor assembly to the seat track.

  • Patent number: 11091182
    Abstract: Disclosed are various embodiments for a multi-surface cart that can be modified or configured to move along different underlying surfaces. The cart can include a transport unit and an adjustable base unit that extends below a bottom surface of the transport unit. The adjustable base unit can be adjusted such that the cart is movable along a first surface in a first configuration with a plurality of wheels on the first surface and is moveable along a second surface in a second configuration with an underlying panel of the adjustable base unit on the second surface.

  • Patent number: 10745213
    Abstract: In one embodiment, a sortation system has a conveyor system and mobile drive units. The conveyor system has a conveyor surface that carries payloads along a direction that extends from a first conveyor end to a second conveyor end. The conveyor system has support structure that supports the conveyor surface above a floor so as to define a space between the conveyor surface and the floor. The space is sized so that the mobile drive units can drive under the conveyor surface towards the second conveyor end. The conveyor system has sensors supported that are positioned to detect positions of the mobile drive units under the conveyor surface. The conveyor system moves at least a portion of the conveyor surface based on the sensors detecting the presence of each mobile drive unit so as to synchronize movement of the payloads from the conveyor surface to the mobile drive units.

  • Patent number: 10689200
    Abstract: In one embodiment, a sortation system at a facility has a conveyor system and a mobile drive unit system. The conveyor system has a conveyor surface that transfers payloads to the mobile drive units, and a controller that communicates a payload identifier for each payload to the mobile drive unit system. The payload identifiers are masked such that information about the local destinations are unknown to the conveyor system. The mobile drive unit system determines the local destinations from the payload identifiers by unmasking the payload identifiers, and delivers the payloads to determined local destinations at the facility.
