The present disclosure provides an electronic label and a method for driving the same. The electronic label includes: a plurality of display screens; a communicator configured to receive content data to be displayed on the plurality of display screens; and a controller comprising a serial data interface and configured to transmit, through the serial data interface, the content data to be displayed on the plurality of display screens and a control signal generated by the controller for controlling the plurality of display screens to the plurality of display screens respectively, so as to control the plurality of display screens to display the respective content data received according to the control signal.

Systems and methods to co-locate RFID readers with in-band sensor networks, such as LoRa sensor networks, are disclosed herein. An example arrangement is a co-located device that includes a dual-mode transceiver configured to communicate with targets operating in a first protocol (e.g., RFID) and other targets operating in a second protocol (e.g., LoRa). The example arrangement includes a dual-mode controller that operates the dual-mode transceiver to communicate via the first protocol during a first time period while disabling communication via the second protocol and to communicate via the second protocol in a second time period while disabling communication via the first protocol.

Methods, systems, and devices are described herein for reading at least one dice. In one aspect, a method may include transmitting an RFID signal proximate to at least one dice, for example, which is contained within a dice gaming system. The method may also include receiving at least two RFID responses, with each of the RFID responses associated with different faces of at least one dice. A first RFID response may be associated with a first signal strength and the second RFID response associated with a second signal strength. The method may further include determining which side of the dice is facing upwards based on the first signal strength and the second signal strength using machine learning.

An RFID portal reads multiple associated RFID tags on articles in groups moved through an RFID code reader having interrogation/charging and receiving/detection antennas concentrated on the group when in a reading zone. The articles are movable through a passage between the reading zone and an outside area. The passage has conductive walls at the reading zone associated with antennas for applying and collecting focused RF signals, and the walls define a vestibule lined with broadband or specific stopband electromagnetic damping structures as well as elongating signal paths into and/or out of the reading zone. Attenuation by one or more of broadband and stopband damping and signal path elongation can achieve 10 dB attenuation or more, sufficient to minimize interaction with stray RFID tagged articles that may be outside of the group in the reading zone.

A system and method for hands-free stock picking using radio frequency identification (RFID) includes a fixed RFID reader configured to interrogate RFID tags associated with inventory that is disposed on shelving, and an RFID barrier that is configured to substantially inhibit interrogation of RFID tags associated with active inventory on the shelving. The RFID reader receives responses from the replenishment inventory on the shelving which are tabulated. When an item is picked from the active inventory and moved away from the RFID barrier, the RFID reader receives an increased number of responses for that item compared to the tabulated inventory. The system then associates the picked item with the associated customer order.

An identification system is provided employing tags which may be targeted by a coherent energy beam such as a laser emanating from a query device controlled by a user. The tags may be activated with great precision even when tightly grouped and at great distances from the user through the employment of the communicated beam to activate the tags to report an identifier and or data stored thereon. The tags may be enable to rebroadcast a signal intended for another tag or form another tag in response to a receiver. The emanating laser is also adjustable for cross sectional contact area to increase accuracy. Security may be provided through the requirement of a proper query code being communicated to the tag prior to generation of a wireless data or identifier response.

Provided is a tag communication device performing wireless communication with an RFID tag including a light emitting unit. The tag communication device includes a communication unit, an imaging unit, and a control unit. The control unit (i) acquires tag IDs of one or more RFID tags present in a communicable range of the communication unit, (ii) transmits a light emission instruction to at least some of the RFID tags corresponding to the acquired tag IDs, (iii) measures a distance between the imaging unit and a position where the light emitting unit emits light based on the light emission instruction on the basis of imaging information of the imaging unit, and (iv) performs a predetermined operation on the RFID tag to which the light emission instruction is transmitted, in a case where it is determined that the distance is within a predetermined range.

A flexible antenna for a wireless X-ray dosimeter chip is described. The flexible antenna includes a dipole antenna associated with an artificial magnetic conductor, wherein the artificial magnetic conductor includes: a top layer configured to partially act as a reflective surface; a bottom conductive ground plane layer configured to prevent propagation of incident electromagnetic waves and to reflect the electromagnetic waves; and a middle layer including a foam material configured to provide an appropriate phase delay between incident electromagnetic waves from the top layer and the reflected waves from the ground plane layer.

Systems and methods for implementing a radio frequency identifier (RFID) system are provided. The methods include transmitting a radio frequency (RF) signal, by an RFID interrogator with multiple antennas. The methods include receiving a superimposed received signal. The superimposed received signal includes replies from a first RFID tag and a second RFID tag that are overlapping in time. The methods also include separating the replies from the first RFID tag and second RFID tag though spatial processing of the superimposed received signal.
