    Abstract: A cart includes a chassis configured to carry a basket and a support structure having a carrier coupled to the chassis, a pair of rear legs coupled to the carrier, and a pair of front legs coupled to the carrier, at least one of the pair of front legs and the pair of rear legs having motor driven wheels coupled thereto, at least one carrier actuator configured to move the chassis relative to the carrier, the pair of front legs including actuators which are configured to extend and retract the pair of front legs, and the pair of rear legs including actuators which are configured to extend and retract the pair of rear legs. The cart includes at least one sensor supported on the cart. The cart also includes at least one processing unit configured with software instructions that enable autonomous self-loading of the cart into a vehicle. The processing unit receives signals from the at least one sensor and providing command signals to any of the wheel motors, the at least one carrier actuator, the front leg actuators, and the rear leg actuators.

    Abstract: Examples of systems and methods for locating movable objects such as carts (e.g., shopping carts) are disclosed. Such systems and methods can use dead reckoning techniques to estimate the current position of the movable object. Various techniques for improving accuracy of position estimates are disclosed, including compensation for various error sources involving the use of magnetometer and accelerometer, and using vibration analysis to derive wheel rotation rates. Various techniques utilize characteristics of the operating environment in conjunction with or in lieu of dead reckoning techniques, including characteristic of environment such as ground texture, availability of signals from radio frequency (RF) transmitters including precision fix sources. Navigation techniques can include navigation history and backtracking, motion direction detection for dual swivel casters, use of gyroscopes, determining cart weight, multi-level navigation, multi-level magnetic measurements, use of lighting signatures, use of multiple navigation systems, or hard/soft iron compensation for different cart configurations.

    Abstract: A bracket assembly includes a bracket for attachment to a shopping cart and a cover connected to the bracket and covering at least part of the bracket. The bracket includes a metal plate having first and second faces, where the length is greater than the width, and the width is greater than the thickness. The bracket has a projection extending outward from the first face and a recess extending inward from the second face and corresponding to the projection. The cover has two walls and a cavity defined between the walls, and the bracket is received within the cavity such that the first and second faces each confront one of the walls. The cover further has a slot in at least one wall, such that the cover is press-fit on the bracket and the projection is received in the slot to retain the cover in connection with the bracket.

    Abstract: A method for mitigating the loss of a cart, and a system which monitors each cart out of an inventory list of a plurality of carts. A cart may support a cart apparatus module, a cart data module, and a GPS tracker module. The system further includes a control station module and a data collection module. The cart apparatus module powers and charges an electronic device which is coupled thereto. The cart data module holds cart data pertaining to the cart, such as a cart identity number. The data collection module includes a plurality of data exchangers to derive cart data when a cart enters in communication range therewith. The control station module is coupled in communication with each data exchanger, and is configured to collect cart data via each data exchanger, store data exchanger location, and for each cart, to process and correlate time data, cart data, and stored data to derive a cart status condition, detect selected cart status conditions and recognize them as cart related event(s), and deliver a report notice in response to such event(s).
