  • Publication number: 20160314434
    Abstract: A method and associated system for managing an item in a place. Positional information about an operating object and positional information about the item is monitored at regular intervals by a receiver receiving locational coordinates of a tag associated with the item and a tag carried by the operating object. Based on the positional information, it is detected i) that the item in the place is being moved, (ii) that the operating object inside the place is moving, (iii) a distance between the location of the operating object and the item, and (iv) that the operating object inside the place and the item in the place are within a previously specified distance of each other. After the previous detections, it is determined that the operating object has illegitimately taken the item, which triggers preventing the operating object from removing the item from the place.

    Abstract: A method and associated system for managing an item in a place. The method detects that: (i) the item in the place is being moved, (ii) an operating object inside the place is moving, and (iii) the operating object inside the place and the item in the place are within a previously specified distance of each other. Responsive to the previous detections, it is determined that the operating object does not have a reservation for borrowing the item, from which it is determined that the operating object has illegitimately taken the item, which triggers preventing the operating object from removing the item from the place.
