  • Patent number: 11984003
    Abstract: Devices, systems, and methods for removing a security tag from an article are disclosed herein. A device for removing a security tag includes a housing including an opening positioned to receive the tag and at least a portion of the article. A magnet is supported adjacent the opening to retain a tag body and to release a retainer pin therefrom when the tag is inserted into the opening. A pin retractor is positioned in the housing opposite the magnet to capture the retainer pin and retract it from the tag body. The pin retractor is retracted into a collar to strip the pin from the pin retractor. A release frame is positioned proximate the magnet and movable between a first position wherein the magnet retains the tag body, and a second position wherein the tag body is moved away from the magnet, thereby releasing the tag body from the magnet.
    Type: Grant

  • Patent number: 11448508
    Abstract: Systems and methods for generating maps for retail environments and other indoor locations, such as via autonomous or other automatic processes, are described. In some embodiments, the systems and methods access images of a retail environment captured via multiple security cameras placed within the retail environment, and generate a two- or three-dimensional digital, virtual and/or interactive map that depicts a layout of the retail environment based on features extracted from the accessed images. For example, the systems and methods may extract and/or determine walkable paths within the images, and generate a two- or three-dimensional map that is based on placing the walkable paths within the retail environment.
