  • Patent number: 10479388
    Abstract: Exemplary embodiments are generally directed to shopping carts and associated systems and methods. Exemplary embodiments of the shopping cart include a shopping cart body and a plurality of wheels supporting the shopping cart body. Exemplary embodiments of the shopping cart include a receiver configured to detect a position of the shopping cart relative to a range of a network or an area defined by a geo-fence. Exemplary embodiments of the shopping cart include an electromagnetic generator operatively coupled to at least one of the plurality of wheels. A resistive load can be selectively connected between an input and an output of the electromagnetic generator to restrict rotation of the at least one of the plurality of wheels as the position of the shopping cart detected by the receiver varies between within or outside of the range of the network or the area defined by the geo-fence.

  • Publication number: 20170221130
    Abstract: Methods and systems are provided for operating a shopping cart communication system. The methods and systems are configured to receive, at an operator terminal of a first shopping cart, operator identifying information. The methods and systems are also configured to generate operator data based on the operator identifying information. The methods and systems are also configured to automatically transmit instructions to configure the graphic user interface of a display device of a second shopping cart to render an image for display to the operator of the first shopping cart, the image comprising a visual representation of the operator data. The methods and systems are also configured to display the rendered image on the display device of the second shopping cart.
