Consistent with disclosed embodiments, systems, methods, and computer readable media for electronic security systems for retail establishments may be provided. Embodiments may include an electronic article surveillance (EAS) gate and at least one receiver configured to receive transmissions from wireless tags associated with products offered by a retail establishment. Embodiments may also include at least one processor configured to receive, from a device operated by a prospective purchaser, a tag ID associated with a specific product for prospective purchase; perform a lookup of the tag ID in a data structure to identify the specific product; initiate an electronic purchase transaction to debit an account associated with the prospective purchaser for purchase of the specific product; and disable an ability to initiate an alarm when the at least one receiver receives a transmission from a tag associated with the specific product in proximity to the EAS gate.

Consistent with disclosed embodiments, systems, methods, and computer readable media for electronic security systems for preventing theft of returned goods may be provided. Embodiments may include an electronic article surveillance (EAS) gate in an establishment and at least one receiver configured to receive transmissions from wirelessly transmitting tags. Embodiments may also include at least one processor configured to receive, from a mobile communications device associated with a previous purchaser, a notification of intent to return a previously purchased product to the establishment; identify a unique tag ID of a specific wirelessly transmitting tag associated with the previously purchased product; update a data structure to indicate that the previously purchased product was returned to the establishment; and enable an ability to initiate an alarm when the at least one receiver receives a transmission from the specific tag associated with the previously purchased product in proximity to the EAS gate.

An aspect of the present disclosure is related to a medication dispensing device that includes a housing with an interior. A plurality of cartridge slots are located in the interior, and each of the cartridge slots includes a drive mechanism. A plurality of cartridges are removably disposed in respective ones of the cartridge slots. Each cartridge includes a stationary hub and a rotational wheel. The stationary hub has a window, and the rotational wheel has a plurality of medication chambers that contain medications. The rotational wheel is disposed in the stationary hub. The drive mechanism of the respective cartridge slot is operably connected with the drive wheel and is configured to rotate the rotational wheel relative to the stationary hub to selectively align the medication chambers with the window to dispense the medications contained in the medication chambers out of the cartridge.

Systems, methods, apparatuses, and computer program products for backscatter RFID communication security. In some example embodiments, a system may include a RFID reader, and a passive RFID tag. A desired direction channel H.sub.θ.sub.R between the RFID reader and the passive RFID tag is H.sub.θ.sub.R=[e.sup.j2π cos θ.sup.R e.sup.jπ cos θ.sup.R e.sup.−jπ cos θ.sup.R e.sup.−j2π cos θ.sup.R]. In certain example embodiments, a system includes a first RFID reader, a second RFID reader, and a passive RFID tag. The first RFID reader is aware of the location of the second RFID reader and the location of the passive RFID tag. The second RFID reader is aware of the location of the first RFID reader and the location of the passive RFID tag. The first RFID reader and the second RFID reader are aware of each others generated reader signals.

Systems and methods for enhanced fault tolerance for a radio frequency identification (RFID) phased array antenna are provided. The systems include a RFID reader that includes (i) a phased array antenna having N antenna elements; and (ii) a controller operatively connected to the phased array antenna. The controller is configured to (1) monitor a characteristic for each antenna element of a set of the N antenna elements; (2) based on the characteristic, detect a fault of a faulty antenna element of the set of the N antenna elements; and (3) responsive to detecting the fault of the faulty antenna element of the set of the N antenna elements, adjust a parameter of at least one other antenna element of the N antenna elements, wherein the parameter is a weight applied to a signal that is transmitted to or received at an antenna element.

The present invention provides an electronic shelf label communication system, method and apparatus. The system comprises: a processor configured to send update data to a wireless access point corresponding to an electronic shelf label group where an electronic shelf label requiring data update is located; the wireless access point configured to send a group wakeup message to the electronic shelf label requiring data update, and send, after the electronic shelf label requiring data update wakes up according to each of countdown durations for receiving the update data, the unsent update data packages corresponding to the electronic shelf label to electronic shelf labels requiring data update in a same electronic shelf label group simultaneously, until all of the update data packages corresponding to the electronic shelf label are sent; and the electronic shelf label configured to wake up periodically, receive the group wakeup message and obtain the plurality of countdown durations for receiving the update data, and wake up again according to each of the countdown durations for receiving the update data, and receive the unreceived update data packages once, until all of the update data packages are received.
