Abstract: A metadata-driven merchant feed processing system is described herein. A merchant providing an online marketplace for the sale of items by a variety of sellers implements a feed processing mechanism driven by feed metadata. The feed metadata consists of declarative metadata statements that model the semantics for transforming seller-facing feed data describing the seller's items to customer-facing listings data to be loaded to an item catalog. The feed metadata captures differences between different versions of the item catalog by maintaining the semantics of the product categories and attributes of the item catalog as of a certain version. Similarly, semantics in the feed metadata modeling new product categories and/or attributes are utilized to support supplemental feeds from sellers to support new features and improvements in the item catalog. The metadata driven feed processing system also provides support for multiple types of seller-facing data entities and feed formats through metadata mapping.

Abstract: Method and apparatus for multi-destination pick using motes. In embodiments, each receptacle may be assigned to a destination and may have a sensor that detects when an item is placed in the receptacle to deactivate the indicator and/or to verify that the item was placed in the correct receptacle. The sensor may be coupled via a wired or wireless connection to a mote that may include a communication interface for communicating with a control system and with other motes in an ad-hoc network. In some embodiments, each mote may also include an indicator that may be activated by a control system to indicate to the agent that the receptacle is the destination receptacle for a picked item. The agent may then place the item in the indicated destination receptacle. In one embodiment, the mote on the destination receptacle may be activated when the picked item is scanned by the agent.

Abstract: A visible-light based display system may be used to project visual guidance to picking and/or stowing agents in a materials handling facility dependent on their current location. The system may comprise a plurality of fixed-location display devices and/or mobile display devices coupled to a control system. The control system may send messages to particular ones of the display devices for projection of visual guidance usable to direct an agent to a particular inventory area in which an item is to be stowed or from which an item is to be picked, to identify a particular position within an inventory area, and/or to identify a particular item stored within an inventory area. The messages may include location, position, and/or descriptive information associated with an item to be stowed or picked. The projected visual guidance may include light or laser beams, text, graphics and/or images, and may be agent-specific, item-specific, and/or order-specific.

Abstract: A method and system for agent exchange-based materials handling. According to one embodiment, a method of agent exchange-based order fulfillment may include a number of agents moving along respective paths through an inventory storage area of a materials handling facility. While moving through the inventory storage area, a portion of the number of agents may respectively select one or more of a number of items stored within the inventory storage area, where each one of the selected items is specified in a corresponding customer order or materials request. The method may also include conveying the selected items to one or more corresponding processing areas of the materials handling facility in order to fulfill the corresponding customer orders. Further, at least some of the selected items may be exchanged one or more times among the agents in the course of being conveyed to corresponding processing areas.

Abstract: Positional placement guidelines for storing items in an inventory area may allow determination and tracking of the position of the items in the inventory area. Position information may be associated with each item in a materials handling facility to assist in locating an item in an inventory area. The position information may represent a position relative to the inventory area and/or to the other items therein. Position information may be determined based on a count of items in the inventory area or based on a time stamp corresponding to the time the item was stored in the inventory area. Position information may be presented to an agent to facilitate picking the item with or without descriptive information. Feedback may provide an indication that the position information is incorrect and may trigger a review or a reset of position information for one or more items in the inventory area.

Abstract: A method and system for transferring selected items among agents within a materials handling facility. According to one embodiment, a method may include a number of agents moving along respective paths through an inventory storage area of a materials handling facility. While moving along a respective path, a first agent may select items from the inventory storage area to be delivered to a corresponding order processing area, where each of the selected items may be specified in a corresponding customer order and at least two of the selected items may be delivered to two different corresponding order processing areas. After the first agent selects a particular item, the first agent may transfer the particular item to a second agent, and the second agent or another one of the agents may deliver the particular item to the corresponding order finalization area.

Abstract: Images may be captured of items being processed at a processing station of an order fulfillment center and made available electronically for review to verify quality assurance polices for the items. Alternatively, a short video clip may be captured of the items being processed. The images may be made electronically available for review from remote locations. The images may be associated with a customer order and the images may be reviewed to ensure that the order has been correctly processed. The processing station may be a shipping station and the images may be reviewed to ensure adherence to shipping quality assurance policies. The processing station may also be a receiving station and the images reviewed for defects in the shipping container or the items. The items may be associated with a returned customer order and the images may be reviewed to verify the validity of a customer complaint.

Abstract: One or more images of items for an order being processed at processing station of an order fulfillment center may be captured and associated with the order. Alternatively, a short video clip may be captured of the order being packaged. An electronic notification that the order has been processed may be sent to a customer associated with the order. The electronic notification may include a reference to one or more of the captured images or video clips. The customer may use a reference included in the notification to view the captured images. The customer may view captured images to verify that the order has been correctly processed. The captured images may include images of the items being packaged for shipment and may show the shipping address on the package allowing the customer to verify that indeed it is his package in the images.

Abstract: Method and apparatus for indirect asset tracking in materials handling environments with Radio Frequency Identification (RFID). In one embodiment, receptacles in a materials handling facility may be equipped with RFID tags. Agents within the materials handling facility may be equipped with RFID readers, which may be integrated in or attached to gloves, wristbands, or other devices. The location of each receptacle to which an RFID tag is attached may be associated with the unique identifier of the RFID tag. When an agent's hand approaches or enters a receptacle equipped with an RFID tag, the RFID reader may detect the presence of the RFID tag. This information, in combination with known information such as the location of the receptacles, may be used, for example, for information gathering and/or for quality checking in picking, stowing, rebinning, and/or other materials handling processes.
