A method for providing data to a group of devices on a pallet includes: positioning a set of NFC antennas at different locations around a perimeter of the pallet, each antenna of the set of NFC antennas being configured to surround the pallet; broadcasting, by an NFC reader/writer utilizing the set of NFC antennas, an identification command simultaneously to the group of devices on the pallet, each device of the group of devices including an NFC tag storing a unique ID indicator; receiving, by the NFC reader/writer, unique ID indicators from each device of the group of devices that receives the identification command, transmitting, by the NFC reader/writer, individual commands to each device of the group of devices to enable energy harvesting by the NFC tag. The energy harvested by each device provides power to operate a processor and a nonvolatile memory of the device in a low power mode.

A method includes receiving, by an RF receiving circuit of a passive wireless sensor of a wireless communication system, an RF signal. When a sensing element of the passive wireless sensor is exposed to an environmental condition, the method further includes affecting, by the sensing element, resonant frequency of the RF receiving circuit. The method further includes determining, by a processing module of the passive wireless sensor, a first value for an adjustable element for a known environmental condition, determining a second value for the adjustable element for an unknown environmental condition, determining a difference between the first and second values that correspond to a change, generating a coded value representative of the change, and transmitting the coded value. The method further includes receiving, by a second processing module of a sensor computing device of the wireless communication system, the coded value and determining a sensed environmental condition.

A method for tracking the activity of animals confined in a facility including at least one cage, a plurality of antennae arranged underneath the at least one cage, an RFID reader to which the plurality of antennae are connected, a computer capable of controlling transmission and reception by the RFID reader, and an RFID tag to be fitted to an animal confined in the cage, the method including that the following steps are carried out:—the animal is fitted with the tag,—the RFID reader generates the transmission of an electromagnetic wave at the plurality of antennae,—the RFID reader identifies which antenna(e) has/have received the response transmitted by the tag,—the computer analyses over a given period which antennae have received a signal transmitted by the tag, thus determining the consecutive positions of the animal.

The present invention broadly relates to a multi-layer electromagnetic coupler arrangement, for encoding an RFID tag, suitable for being used in a printing device. The coupler arrangement employs a differential transmission line loop, as a coupling element arranged on a top surface layer of the multi-layer arrangement, which is arranged close to a metallic ground plane layer for shielding on the side opposite the top surface. Coupling is achieved by inductive coupling in the reactive near field and based on the fact that each RFID tag comprises a current loop, itself. The differential property of the transmission line loop is achieved by feeding the terminals of the loop with signal parts having a phase shift of 180° with respect to each other. The feeding components are arranged on the opposite side of the ground plane with respect to the top surface layer comprising the current loop. It is possible to arrange plural differential transmission line loops on the top surface layer, in form of a one-or two-dimensional array.

A charging connection is provided for charging a battery of a vehicle using an external power source. The first connector is coupled to the external power source with an electric cable. The second connector is coupled to the vehicle. The first connector is automatically guided for connection to the second connector using radio frequency signals to couple the first and second connectors so that electrical energy is supplied to the vehicle from the first connector to the second connector.

The present invention provides for a RFID tag assembly that is suitable for operation with at least one RFID reader assembly. The RFID tag assembly comprises, inter alia, an antenna member for transmitting and/or receiving an RFID signal, and at least one integrated circuit (1C) for processing the RFID signal and which is configured to communicate, alternatingly and sequentially in time, a first signal transmission and at least one second signal transmission, each defined by a plurality of predetermined signal transmission parameters, to the at least one RFI D reader assembly, utilising time-division multiplexing, wherein the at least one first signal transmission differs from the at least one second signal transmission in at least one of said plurality of predetermined signal transmission paameters.

An RFID system includes an RFID antenna assembly configured to be positioned on a product module assembly of a processing system. The product module assembly is configured to releasably engage at least one product container. A first RFID tag assembly configured to be positioned on the at least one product container. The at least one product container is configured to position the first RFID tag assembly within a detection zone of the RFID antenna assembly whenever the product module assembly releasably engages the at least one product container.

An apparatus for managing an inventory of goods stored in multiple bins on a shelving system includes an RFID antenna disposed on an upper shelf of the shelving system. The RFID antenna communicates with RFID tags disposed above the upper shelf RF shielding is disposed between the RFID antenna and lower shelves. An RFID tag is attached to a bin configured to contain the goods. The RFID tag is encoded with information identifying the goods stored in the bin. An RFID reader performs scans to detect RFID tags disposed above the upper shelf. An inventory computer generates a bin detection confirmation message based on the RFID tag being detected by the RFID reader at least a first number of times during a predetermined detection period. The inventory computer also generates a product reorder message based on the RFID tag being detected by the RFID reader at least a second number of times during the predetermined detection period, wherein the second number of times is greater than the first number of times. The product reorder message includes the information identifying the goods stored in the bin.

A planar conductor device and RFID chip are folded to create a coil to form an RFID tag. The result is the formation of a solenoid coil, not planar, which allows the device to be placed against metal. Specifically, the planar structure is folded into a concertina fold. After folding, a spiral conductor is formed in the Z direction, forming a coil with the RFID chip connected to both ends. This structure operates as a resonant RFID tag.

An airport baggage recording system. The airport baggage recording system comprises a telescopic robotic arm that loads airport baggage. The robotic arm has one end connected to an upright by a pivot and a second end connected to a disc. A radio frequency identification (RFID) reader is located in the disc that reads RFID tags on the airport baggage when the airport baggage is placed on the disc during loading. Another RFID reader is located on the pivot that reads the RFID tags on the airport baggage when the airport baggage is placed on the disc during loading. The RFID reader in the disc and the RFID reader on the pivot both read the RFID tags on the airport baggage to prevent errors in reading the RFID tags on the airport baggage during loading.
