  • Patent number: 11068841
    Abstract: Embodiments presented herein describe a location aware, RFID-enabled pallet mover for tracking inventory moving in a warehouse. The pallet mover includes a RFID system for detecting a pallet currently loaded on the pallet mover and a real-time location system (RTLS) tag for identifying a location of the pallet mover in the warehouse. In one embodiment, the RFID system includes an antenna and an RFID reader for detecting RFID tags in order to track inventory such as a pallet or packages. The RFID reader can communicate with the RFID tags in the environment to identify which pallet is currently loaded on the mover. In one embodiment, the RFID system waits until the pallet mover is moving before activating the RFID reader and monitoring a received signal strength indicator (RSSI) of an RFID tag to determine whether the corresponding pallet is currently loaded onto the pallet mover.

  • Patent number: 10643038
    Abstract: Techniques for monitoring objects being placed onto a plurality of pallets. A controller is configured to analyze images captured by the plurality of camera devices to determine when a first object is placed onto a first one of the plurality of pallets. Upon determining that the first object has been placed onto the first pallet, the controller can determine a first identifier corresponding to the first object using the RFID reader corresponding to the first pallet and can determine an intended pallet corresponding to the first object. Upon determining that the first pallet onto which the first object was placed is not the intended pallet for the first object, the user is notified using the feedback mechanism.

  • Patent number: 10565410
    Abstract: Embodiments herein describe a package management system that uses two operation modes of RFID readers (i.e., an inventory mode and a search mode) to provide feedback to an associate when a package has been mis-sorted. In one embodiment, the RFID readers are attached to one or more RFID antennas which each are disposed overhead a respective container or storage location in a warehouse. For example, each of the antennas may have a beam pattern or read region that covers the container. Using the RFID antennas, the RFID reader can query the RFID tags in the container to identify the packages stored in the container. In one embodiment, the RFID reader switches to the search mode after a new package is identified. Using the search mode, the RFID reader can quickly identify when the package is stored in the container and provide prompt feedback to the associate.

  • Patent number: 10474980
    Abstract: A system for providing access to delivery locations with added security. The system can include a database of images (or other data) of keys associated with a plurality of delivery addresses, or secure delivery locations. When a special handling item—i.e., one that cannot safely be left outside the delivery location—is ordered, the system creates a key to provide access to the secure delivery location. The key can be a one-time use, disposable, shreddable, or otherwise temporary key. The system can also utilize one or more video cameras to record some or all of the delivery process to ensure the delivery driver delivers the item(s), destroys or leaves the key, and leaves the secure delivery location locked, among other things. The manufacturing of a key and/or the choice to use secure delivery can be based on the delivery location, product, delivery value, perishability, or other factors.

  • Patent number: 10460137
    Abstract: A method of interrogating a plurality of RFID tags comprises interrogating a first RFID tag with a read command comprising a masking value for a predefined portion of a User Memory Bank of the first RFID tag. The predefined portion stores state information for the first RFID tag. The masking value corresponds to a non-quiesced state relative to the read command interrogation. The method further comprises receiving a response from the first RFID tag that indicates that the first RFID tag is in the non-quiesced state. The method further comprises interrogating the first RFID tag with a write command that instructs the first RFID tag to write a predefined value to the predefined portion of the User Memory Bank, wherein writing the predefined value to the predefined portion places the first RFID tag in a quiesced state relative to a subsequent read command interrogation comprising the masking value.

  • Patent number: 10366257
    Abstract: The embodiments herein measure the tag to noise ratio (TNR) for a tag on an item (e.g., a package) to determine a location of the item in a warehouse. In one embodiment, the TNR is derived by comparing a measured performance parameter for a tag of interest to the combined measured performance parameters for other tags measured by the same reader or for the same tag when measured by a different RFID reader. The higher the TNR, the greater likelihood the tag is within an area assigned to the reader. In another embodiment, the TNR is derived from comparing the signal strength of a tag as measured by multiple RFID readers. In another example, respective TNR values for a plurality of tags detected by a reader can be compared to determine which tag is being carried by an associate.
