Abstract: A method and apparatus for a co-located Radio Frequency Identification (RFID) device and ultrasonic device includes an RFID reader loop antenna element oriented parallel to a reflector panel. An ultrasonic emitter is disposed through an aperture in the reflector panel with a horn that extends through the loop element. The horn can serve as a mounting structure for the antenna element. A diameter of the aperture is less than one-quarter wavelength of an operating frequency of the RFID reader loop antenna element. The aperture is located in the reflector panel near a minimum E-field area of the RFID reader loop antenna element.

Abstract: An anti-fraud security tag removal system reads product identifiers on groups of items presented for purchase at a point of sale area. The product identifiers indicate how many of the items include security tags that must be removed. A security tag detacher removes security tags only on items for which the system has detected that the item was present, preventing removal of security tags on items which were not read by the point of sale system. An RF antenna and a security tag detacher are co-located such that the product identifier of the item is highly likely to be read when a sales clerk removes the security tag. The product identifier may be incorporated into the security tag and disabled when the security tag is attached to the item. The product identifier may be shunted by the security tag.

Abstract: Systems and methods for adaptively optimizing RFID-based POS performance are described. In various aspects, one or more processors and one or more image sensors are configured to aggregate images, where the images are captured by the image sensor(s) and where the image sensor(s) are associated with an RFID reader. A first density value and a second density value may be determined based on the image(s), where each of the first density value and the second density value is associated with a respective a first or second set of individuals, or a first or second set of products, located within a respective first and second POS lane. The second POS lane is positioned adjacent to the first POS lane. The first density value and the second density value are used to update a reader parameter associated with the RFID reader to optimize the RFID reader.

Abstract: Systems and methods for identifying new radio frequency identification (RFID) tag events within a particular vicinity of an RFID reader are described. In various aspects, a processor causes image sensors to capture a first set and a second set of video images, where the first set depicts a first RFID tag environment and the second set depicts a second RFID tag environment. The first RFID tag environment is static without a person moving within the first RFID tag environment and the second RFID tag environment is active with at least one person moving within the second RFID tag environment. An environment database may be generated and updated with static analytic information and active analytic information based on the first set and second set of video images, respectively. The processor may determine a RFID tag event based upon the static analytic information and the active analytic information.

Abstract: A radio frequency (RF) identification (RFID) reader is mounted in a venue in proximity to a portal that is openable and closable by a door. The portal reader reads RFID object tags associated with objects that approach the portal. An electrical conductor is associated, and jointly movable, with the door. A portal RFID tag is mounted at the portal. The portal tag is overlain by the electrical conductor in a closed door position and is remote from the electrical conductor in an open door position. The portal tag is readable by the portal reader in either the open or the closed door position. A controller identifies any objects that have passed through the portal based on whether the object tags have been read, as well as whether the portal tag has been read in either the open or the closed door position.

Abstract: Systems and methods for product reader control are described. In various aspects, the product reader control is enhanced with image sensor(s) for steering product reader(s) to determine product attributes associated with scanned products. The product reader control system and methods may capture, with the image sensor(s), one or more images associated with a product. The product may have a product identifier and the product may be located within an onsite venue. Based on the detection of the product identifier in the image(s), a first product reader may be steered in a direction of the product, where the first product reader is located within the onsite venue with the product. The first product reader may scan the product such that the scanning determines at least one attribute associated with the product.

Abstract: A system and method for density-based RFID network configuration. In various aspects, an RFID reader executes a read cycle defined by dwell times for a low RFID tag density and a high RFID tag density setting. Accordingly, a controller may cause the RFID reader to implement one or more RFID protocols. The controller may then receive data corresponding to the RFID tags from the RFID reader to determine a number of RFID tags within read range of the RFID reader. Based on the number of RFID tags, the controller may determine an adjustment to the read cycle executed by the RFID reader. The controller may then configure the RFID reader to execute the adjusted read cycle.
