Abstract
The inventions involve material handling apparatus developed to operate in radio frequency rich environments. Articles are provided having at least one large compartment capable of enclosing at least one electronic device or a package populated with a plurality of devices. RFID tags are also provided having three antenna arrays situated on three planes to improve electromagnetic and electrostatic coupling with an external distributed network of devices. Pallets are provided with cellular communications devices to provide track and trace functionality. Sensors and actuators are used in connection with the material handling apparatus.
Claims20
A communications system for a material handling apparatus comprising:
- a detectable RFID device having a first memory section and a second memory section,
- said first memory section containing first means to identify the apparatus, and
- said second memory section containing second means to indicate a condition of the apparatus.
A communications method comprising:
- placing a first detectable RFID device having a first memory section and a second memory section onto a pallet,
- providing a first identification code in the first memory section to uniquely identify the pallet,
- using the pallet to transport an object,
- identifying the object with a second detectable RFID device,
- producing a second identification code with the second detectable RFID device, and
- copying the second identification code into the second memory section to indicate a condition of the pallet.
A communications device for a pallet comprising:
- an RFID tag,
- said RFID tag having a first memory section for storing a first level identification code to uniquely identify the pallet, a second memory section for storing a second level identification code to uniquely identify an owner of the pallet, and a third memory section for storing a third level identification code to uniquely identify a user of the pallet, and
- said codes indicating a condition associated with said pallet.
A pallet recycling system for managing a pallet to support pallet recycling comprising:
- a managing section connected to a network to manage pallet distribution;
- a pallet including a radio tag, said radio tag recording and transmitting pallet distribution information;
- a tag reader/writer to read out the pallet distribution information recorded in said radio tag to write the pallet distribution information to said radio tag, and to communicate with said managing section,
- said radio tag having a read-only memory having a serial number of said radio tag recorded therein, a first dedicated memory region where information corresponding to a pallet owner information is recorded using said tag reader/writer, and a second dedicated memory region where user information is recorded using said tag reader/writer;
- and
- said tag reader/writer writing to said first dedicated memory region of said radio tag updated pallet owner information.
A radio frequency identification system comprising:
- a radio frequency identification tag that includes a memory with a first page having a page size that is defined by a first predetermined number of bytes and a second page having a page size that is defined by a second predetermined number of bytes;
- wherein the first page and the second page include data that identifies objects to be tracked by the radio frequency identification tag;
- a radio frequency identification interrogator that is configured to interrogate the radio frequency identification tag;
- a server that communicates with the radio frequency identification interrogator to interrogate the first page and the second page;
- and
- wherein the identified objects are associated based on a relationship between the first page and the second page.
