A position detection system 1 identifies position information on the basis of a position signal received from a storage medium 30P disposed in a placement area where a target item is placed, identifies item information on the basis of an item signal received from a storage medium 30Q attached to the target item, and associates the position information with the item information and stores the associated information when the item signal is received during a period of time that starts from a time at which the position information is identified and that does not exceed a predetermined length of time.

Systems, methods, and computer-readable media for adding beauty products to tutorials are presented. Methods include accessing video data comprising images of a presenter creating a tutorial, the tutorial depicting the presenter applying a beauty product to a body part of the presenter. Methods further include processing the video data to identify changes to the body part of the presenter from an application of the beauty product, and responding to identifying changes to the body part of the presenter from the application of the beauty product by processing the video data to identify the beauty product. Methods further include retrieving information regarding the beauty product and causing presentation of information regarding the beauty product on a display device.

A system includes one or more assets disposed within a physical location, where each asset is coupled to a wireless tag. Each wireless tag is configured to wirelessly transmit beacon signals at predetermined intervals. The system further includes a gateway configured to cover the range of the physical location. The gateway is configured to scan the physical location to identify beacon signals transmitted by each of the wireless tags and receive the beacon signals from each wireless tag at the predetermined intervals. The gateway is also configured to dynamically optimize a function of the gateway by adjusting a scan frequency based at least in part on a variability of the wireless tags disposed within the physical location.

In some implementations, a system may receive, from a motion sensor, an inactivity indication that indicates a period of inactivity within a physical environment. The system may store, in a data structure, identifiers of a plurality of RFID tags that a tag reader read during the period of inactivity. The system may receive, from the motion sensor, a motion notification that indicates a period of activity within the physical environment. The system may cause the tag reader to collect an identifier of an RFID tag in the physical environment during the period of activity. The system may determine, based on the identifier and the identifiers of the plurality of RFID tags, a movement status associated with the RFID tag during the period of activity and perform an action associated with the movement status of the RFID tag.

Systems and methods are disclosed for radiolocation using backscatter RFID tags and a special-purpose reader that produces a stepped-frequency continuous wave (SFCW) radio frequency (RF) interrogation signal comprising N carrier frequencies. A backscattered interrogation signal from a backscatter RFID tag is down-converted using at least a portion of the generated SFCW RF interrogation signal. Received signal phases (RSP) corresponding to the N carrier frequencies are determined. Received signal strength (RSS) may be determined to improve performance. A distance between the RFID reader and the backscatter RFID tag may be estimated based on at least a summation of differences between RSPs corresponding to adjacent carrier frequencies.

A wireless tag communication device includes a communication interface device configured to communicate with a wireless tag attached to or included in a sheet conveyed along a conveyance direction in a printer, and a controller configured to acquire light reception information indicating a time period in which light emitted towards the sheet has been blocked by the wireless tag during conveyance of the sheet, compare the acquired light reception information to reference information and determine a direction of the wireless tag with respect to the conveyance direction, determine a polarization direction of a radio wave to be transmitted to the wireless tag based on the determined orientation direction of the wireless tag, and control the communication interface device to transmit to the wireless tag the radio wave having the determined polarization direction.

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.

The disclosure concerns systems and methods for controlling access to a device with barcode-reading functionality. Enabling the barcode-reading functionality of the device may require providing authenticating information. A user may provide the authenticating information using an identification card with an embedded near field communication (NFC) tag. After the device or a charger of the device validates the embedded NFC tag, the device may enable the barcode-reading functionality but track an amount of time since a last barcode scan of the device. If the amount of time since the last barcode scan reaches a present period, the device may disable the barcode-reading functionality. The device may send a connection request from a portion of a local area network (LAN). A server may receive the request. The server may deny the device access to the LAN if the device is not authorized for use in the portion of the LAN.

Methods of detecting scan avoidance events during decode sessions are disclosed herein. An example method includes during a timeout period at one or more processors of the symbology scanner, identifying and decoding a transaction affecting indicia on an object in one or more images to obtain a transaction affecting payload; during the timeout period at the one or more processors, identifying one or more visual features in the one or more images; and in response to identifying a non-transaction affecting indicia associated with the one or more visual features, and failing to identify or decode the transaction affecting indicia, determining a potential scan avoidance attempt and generating a scan avoidance alarm signal.

Techniques for eliminating RFID cross-reads for RFID point of sale scanners using imager object tracking are disclosed herein. An example method includes measuring, by an imager a series of displacements of an object from a center of the field of view (FOV) of the imager, over a timeframe; measuring, by an RFID reader, a series of received signal strengths for an RFID tag over the same timeframe; comparing the series of displacements to the series of received signal strengths over the timeframe to determine a measure of similarity between the series of displacements of the object from the center of the FOV of the imager and the series of received signal strengths for the RFID tag over the timeframe; and responsive to the measure of similarity exceeding a threshold measure of similarity, adding a record associated with the RFID tag to a transaction log.
