Abstract: In an exemplary embodiment, an apparatus (10) and associated method for sorting a plurality of items includes a plurality of sort destinations and a plurality of delivery vehicles (200/400) for delivering items to the sort destinations. Each vehicle (400) includes a surface (406) for supporting items to be delivered and an edge-detection assembly (402,404) for detecting an edge of an item when the item is conveyed onto or discharged from the vehicle. The edge-detection assembly (402,404) includes an emitter for emitting a beam of light toward the surface. The emitter (104) is positioned below the surface so that the beam of light is projected transverse the surface. The emitter edge-detection assembly also includes a plurality of detectors for detecting the beam of light, wherein an object on the surface of the vehicle affects the beam of light received by the detectors.

Abstract: The apparatus includes a moveable support platform within the container to reduce a distance that items fall into the container when stowed. The support platform is lowered by a movement mechanism as items are placed into the container. The movement mechanism may be a bladder filled with air, a biasing device, a pneumatic device, or a mechanical device. The moveable support may form a bottom portion of the container during transport of the container. In some instances, the movement mechanism may lift items out of the container to empty the container at a destination.

Abstract: In one embodiment, a system has a carousel that has a guiderail that forms a loop that has a loading position and an unloading position. The carousel also has a plurality of buckets, each having an upper end and a lower end. The lower end includes at least one bottom wall that is moveable between (i) a transporting configuration where the at least one bottom wall substantially closes the lower end of the bucket and (ii) a discharge configuration where the at least one bottom wall is moved so as to define an opening in the lower end of the bucket. The buckets are supported by the guiderail such that the buckets can be driven from the loading position towards the unloading position in the transporting configuration. The buckets can be transitioned to the discharge configuration so as to unload inventory items at the unloading position into a packaging material.

Abstract: A packaging system employs a cartridge having moveable walls such that the cartridge discharges or inducts one or more items into a cavity of a package, such as a film that is sealed into a pouch or mailer. A bottom wall of the cartridge is retracted relative to an end panel of the cartridge during the induction process.

Abstract: Embodiments herein describe techniques for operating lighting systems which can be used by associates who are colorblind or are susceptible to optically induced seizures (e.g., photosensitive epilepsy). In one embodiment, the lighting system includes programmable light sources which permit the lighting system to use colors that a colorblind person can easily distinguish—e.g., red, blue, orange, etc. Put differently, the lighting system can choose colors which are easily distinguishable to a colorblind associate when instructing the associate to take an action. Moreover, the lighting system can pulse a light source by changing its brightness or intensity over time. The lighting system can control a maximum gradient change rate and a maximum intensity change to mitigate a risk of optical seizures when pulsing the light sources to mitigate the risk of inducing a seizure.

Abstract: Embodiments herein describe wireless transmission techniques for mitigating interference between wirelessly controlled machines in a shared space. To mitigate interference, the machines may be assigned different channels within the same frequency band. However, if machines using the same channel in a frequency band receive each other's wireless signals, the wireless signals can interfere. To free up additional bandwidth, in one embodiment, the command signals are transmitted using a different frequency band than a heartbeat signal used to stop the machines in case of emergencies. In another embodiment, time multiplexing or directional antennas can be used to mitigate interference. In another example, antenna diversity and multiple-input-multiple output (MIMO) can be used to further focus the radiation pattern onto the desired machine while avoiding transmitting wireless signals to neighboring machines. In one embodiment, the machines may use dual-channels to transmit and receive duplicate data.

Abstract: Described are systems, methods, and apparatus for automated item singulation. The system includes a singulation station in which a plurality of different type items may be transitioned onto a singulation table. The singulation table activates and the movement of the singulation table causes the items to de-shingle, separate in distance with respect to one another and migrate along the singulation table toward a pick conveyor. As the de-shingled and singulated items arrive on the pick conveyor they are detected and individually picked by a robotic unit and transitioned from the singulation station.

Abstract: Disclosed are various embodiments for an automated package unloading system. An automated package unloading system can include an end effector supported by a supporting frame which is mounted to a conveyor system. The end effector and/or the conveyor can be configured to move into and out of a container containing stacked packages. The end effector can be configured to attach to the packages and pull the packages from their original position. The end effector can further be configured to release the packages onto the underlying conveyor.

Abstract: Sortation systems and methods are described, in which the sortation systems may include a cylindrical sortation tower. The cylindrical sortation tower may include a plurality of sortation levels, and each of the sortation levels may include a plurality of sortation positions arranged around a periphery of the level. Each sortation position may include a sortation container. The cylindrical sortation tower may also include one or more horizontal tracks and vertical tracks, and each of the sortation levels may further include a circumferential track. Shuttles may traverse the horizontal, vertical, and circumferential tracks to transport items to desired sortation containers. Further, robotic arms may remove completed sortation containers from and add empty sortation containers to the cylindrical sortation tower.

Abstract: A conveyor for use in an inventory management system includes a body, one or more displacement elements connected with the body for interfacing with and moving the conveyor along rails, and a sorting mechanism for selectively depositing items from the conveyor to either side of the conveyor. A sorting mechanism includes first and second hinge release assemblies for connecting with, and selectively releasing, a panel that supports the item at either of respective first and second panel ends to allow the panel to fully disconnect at one of the ends and swing open in the first or second direction.

Abstract: In one embodiment, a conveyor system reorients objects from a side-by-side orientation to a sequential orientation. The system has an upper conveyor level and a subsequent conveyor level disposed below the upper level. The upper level has an upper conveyor segment that has an upstream end, a downstream end opposite the upstream end along a flow direction, a pair of lateral sides, a top side, and a bottom side. The upper conveyor segment defines an conveying surface that is between the pair of lateral sides and that carries objects aligned therewith along the flow direction. The upper conveyor segment also defines a discharge opening that is between the conveying surface and one of the lateral sides. The discharge opening extends through the upper conveyor segment along a vertical direction so as to discharge objects onto the subsequent conveyor level that are aligned with the discharge opening.

Abstract: In one embodiment, a conveyor system has a conveyor segment and a knock-down device. The conveyor segment has an upstream end, and a downstream end opposite the upstream end. The conveyor segment defines a conveying surface that carries objects along a flow direction that extends from the upstream end to the downstream end. The knock-down device has a knock-down body that is spaced entirely from the conveying surface along a vertical direction by at least a clearance height. The knock-down body has an upstream body end, a downstream body end offset from the upstream body end with respect to the flow direction, and a ramped surface that extends between the upstream body end and the downstream body end. The ramped surface is ramped away from the conveying surface as the ramped surface extends along the flow direction, and knocks down objects that are stacked on top of one another.
