摘要： A system for monitoring and controlling shopping cart usage comprises a wheel assembly that attaches to a shopping cart. In some embodiments the wheel assembly includes a wheel, a brake that can be activated to inhibit rotation of the wheel, a controller that controls the brake, a VLF receiver, and an RF transceiver. The RF transceiver may, for example, operate in a 2.4 GHz frequency band. In some implementations, the RF transceiver may be used to detect entry of the shopping cart into a checkout area of the store, and the VLF receiver may be used to detect that the shopping cart is exiting the store. The controller may activate the brake if the shopping cart attempts to exit the store without first passing through a checkout area.

摘要： 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.

摘要： A system for monitoring shopping carts or other human-propelled carts includes wireless access points that communicate on a wireless network with wheel assemblies of the carts. The system is capable of monitoring a path followed by a cart in a store or building, and using the path (optionally together with other criteria) to determine whether to authorize the cart to exit. For example, if a shopping cart fails to pass through a checkout lane of a store, the system may perform an action that blocks or inhibits the shipping cart from exiting the store. The wheel assemblies may include LEDs or other visual indicators that alert store personnel when a wheel assembly is in a particular state.

摘要： Examples of systems and methods for controlling or monitoring a fleet of human-propelled, wheeled carts and cart retrievers are described. The carts can be shopping carts at a retail facility, and the cart retrievers can be used to collect and return the shopping carts from a parking lot near the facility to a cart collection area. The carts or cart retrievers can monitor various status or usage parameters (such as retriever battery charge, cart collection trip speed, cart collection path or duration, etc.) and transmit the parameters to a central control unit. The central control unit can analyze and process the status or usage parameters. The system can provide a user interface for access to the status or usage parameters of the cart and cart retriever fleet.

摘要： A vehicle tracking system includes a wheel containing sensor circuitry capable of sensing various types of conditions, such as specific electromagnetic and/or magnetic signals indicative of particular wheel locations. The sensor circuitry is coupled to an RF transceiver, which may but need not be included within the wheel. The wheel may also include a brake mechanism. In one embodiment, the wheels are placed on shopping carts and are used to collect and monitor shopping cart status and location data via a wireless network. The collected data may be used for various purposes, such as locking the wheel of an exiting cart if the customer has not paid, estimating numbers of queued carts, and stopping brake activation events from occurring during mechanized cart retrieval.

摘要： A vehicle tracking system includes a wheel unit containing RF communication circuitry. The wheel units communicate with fixed nodes of a monitoring system. In some embodiments, the wheel units are placed on shopping carts and are used to track the shopping carts in a vicinity of a store. The system may implement a variety of tracking-relating features, including detecting unauthorized store exit events, estimating the number of shopping carts that are clustered together, and inhibiting shopping cart theft.

The wheel units communicate with fixed nodes of a monitoring system. In some embodiments, the wheel units are placed on shopping carts and are used to determine whether particular shopping carts are authorized to exit a store. For example, if a shopping cart that has not passed through a checkout lane is approaching a store exit, the system may activate a shopping cart braking unit, and/or initiate another action to inhibit push-out theft.
