Abstract: A sortation system uses short conveyors or transporter units on a lift to move products or packages to totes in a storage rack. The lift may be a carousel. Automated components remove the totes from the rack and place them on outfeed conveyors. The system to remove the totes can include a transfer vehicle. The sortation system may be modular.

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.

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.
