An inventory system is provided herein, comprising a first inventory system unit and a second inventory system unit. The first inventory system unit comprises at least a configuration transmitter to generate a configuration field inside a first field zone to configure one or more UHF RFID tags within said first field zone into a configured state deviating from a default state. The second inventory system unit therein comprises at least an interrogation transceiver to generate an interrogation field inside a second field zone that is at least partly outside said first field zone to subsequently interrogate a set of one or more UHF RFID tags that are within said second field zone and that are in the configured state as a result of being configured by the configuration transmitter.

A face recognition device includes a screen component, a middle frame and a radio frequency antenna. The screen component is installed on the middle frame, the radio frequency antenna is disposed between the middle frame and the screen component, and the screen component is provided with a clear zone, so that the radio frequency antenna radiates electromagnetic waves outward through the clear zone of the screen component. Since the radio frequency antenna is disposed between the middle frame and the screen component and the screen component is provided with the clear zone, the radio frequency antenna can radiate electromagnetic waves outward through the clear zone on the screen component, so as to establish a communication with an electronic tag.

A system and a method for inspecting components of a turbojet engine using RFID tags and an associated interrogator device. The inspection system includes at least one RFID tag associated with a component of the turbojet engine and an interrogator device arranged so as to be able to communicate with the RFID tag, the interrogator device being equipped with an RFID antenna arranged so as to be able to be inserted into a nacelle compartment of the turbojet engine through an inspection opening intended for the passage of an endoscope probe.

A method for monitoring the surface of a device to physical and/or environmental exposure, the method comprising: • (a) attaching at least one sensor including a reactance autotuning integrated circuit to a surface of a device; • (b) attaching a reader in proximity to the sensor; • (c) measuring a reference reactance of the sensor with the reader at a selected frequency; • (d) continually monitoring for changes in the reactance of the sensor at the selected frequency, wherein changes to the reactance are digitized by the autotuning circuit; and • (e) comparing differences between the reference reactance and changes to the monitored reactance to determine if said surface of the device has been subjected to physical and/or environmental exposure.

A wireless power system includes a primary device and a secondary device. The primary device includes a power conversion unit, a function module, and a transceiver. The peripheral device includes a wireless power receiver circuit, a peripheral transceiver, and a peripheral unit. The power conversion unit converts a power source into an electromagnetic signal. The functional module executes a function regarding peripheral information. The transceiver communicates information regarding the electromagnetic signal and the peripheral information. The wireless power receiver circuit converts the electromagnetic signal into a voltage. The peripheral transceiver communicates the information regarding the electromagnetic signal and the peripheral information. The peripheral unit processes the peripheral information.

An encoding module and related systems and components are provided. The encoding module includes a plurality of encoding elements arranged in an array of columns and rows and one or more switching elements configured to selectively connect the encoding elements to a reader. The connection of the encoding elements may be based on the location of a targeted transponder disposed among multiple adjacent transponders to ensure the selective communication with the targeted transponder only. The module is configured for various types and locations transponders to be used within a system, such as a printer-encoder. Each encoding element may include a loaded conductive strip comprising a loop shape portion and a shield that corresponds to the loop shape portion. In another embodiment, an access control system having an encoding module with the plurality of couplers and an access card having a plurality of transponders corresponding to the couplers is provided.

An electronic voting system is described that utilizes printed vote records (PVRs) in which a voter's vote selections are recorded in voter readable characters. Optical character recognition (OCR) techniques may then be utilized to scan the PVR to record the voter's selections. The OCR data is then utilized to generate the cast vote record. Thus, the electronic voting system directly interprets the voter selections from the PVR just as the voter sees the data. In this manner “what you see is what you get” printed vote record data is provided for a voter's viewing and that same data is used to generate the cast vote record.

The present invention relates to inventory scanning using dual polarization radio frequency identification antennae for automatically reading and locating inventory.

An apparatus can include a plurality of antennas. The apparatus can include a first transceiver coupled to the plurality of antennas. The apparatus can include a second transceiver. The second transceiver can be an RFID transceiver. The apparatus can include a controller coupled to the first transceiver and coupled to the RFID transceiver. The controller can detect the presence of an RFID tag. The controller can retrieve, in response to detecting the presence of the RFID tag, information corresponding to the RFID tag. The information can include radio-frequency shielding information regarding electrically conductive material of an article of clothing. The controller can adjust the first transceiver based on the information retrieved corresponding to the RFID tag.

A system includes a first computing device having a first non-transitory machine-readable storage medium, first communication circuitry, and at least one first processor in communication with the first non-transitory machine-readable storage medium and the first communication circuitry. The at least one first processor is configured to execute instructions stored in the first non-transitory machine-readable storage medium to cause the first communication circuitry to receive a first signal from a first transmission medium, calculate a first authentication value for an object based on data included in the first signal, and cause the first communication circuitry to transmit a second signal to the first transmission medium. The second signal identifies whether the object is authentic based, at least in part, on the first authentication value.
