Abstract: A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

Abstract: A system for use on a shopping cart to enable movement of the shopping cart to be monitored and controlled. The system includes a shopping cart wheel, a braking mechanism configured to inhibit movement of the shopping cart, and electronic circuitry coupled to the braking mechanism, the electronic circuitry configured to detect signals that reflect a current location of the shopping cart wheel, and to transmit status messages via a wireless radio frequency (RF) link, including status messages reflective of the signals detected by the electronic circuitry. The electronic circuitry includes a Very Low Frequency (VLF) receiver configured to detect VLF signals transmitted by a VLF transmitter, and an RF transceiver configured to communicate bi-directionally over the wireless RF link in a frequency band that falls substantially higher than a VLF frequency band. The electronic circuitry further includes a controller coupled to the VLF receiver, the RF transceiver, and the braking mechanism, the controller configured to control the braking mechanism. The electronic circuitry is configured to determine, based at least in part on messages received over the RF link with the RF transceiver, whether to respond to detection of a VLF signal by the VLF receiver by activating the braking mechanism.

Abstract: A system for retrieving shopping carts. The system includes a plurality of shopping carts, each of which includes radio frequency (RF) communication circuitry coupled to a braking mechanism, the RF communication circuitry being capable of receiving RF transmissions of commands. The system further includes a mechanized cart retrieval unit that pushes or pulls a group of nested carts to facilitate retrieval, the mechanized cart retrieval unit configured to communicate with the RF communication circuitry of the nested carts to cause the braking mechanisms of the nested carts to remain unlocked during mechanized cart retrieval. The shopping carts are ordinarily responsive to detection of a lock zone created via a transmitter by locking their respective braking mechanisms, and the mechanized cart retrieval unit is capable, via communication with the RF communication circuitry of the nested carts, of causing the nested carts to disregard the lock zone transmission signal.

Abstract: A vehicle tracking system includes a wheel (32) containing sensor circuitry (88, 90, 92, 94, 96) capable of sensing various types of conditions, such as wheel rotation, wheel vibration caused by skidding, and specific electromagnetic and/or magnetic signals indicative of particular wheel locations. The sensor circuitry is coupled to an RF transceiver (82), which may but need not be included within the wheel. The wheel (32) may also include a brake mechanism (100). In one embodiment, the wheels (32) are placed on shopping carts (30) 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, stopping wheel skid events that occur during mechanized cart retrieval, store planning, and providing location-based messaging to customers.

Abstract: 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.

Abstract: A navigation system uses a dead reckoning method to estimate an object's present position relative to one or more prior positions. In some embodiments, the dead reckoning method determines a change in position from the object's heading and speed during an elapsed time interval. In embodiments suitable for use with wheeled objects, the dead reckoning method determines the change in position by measuring the heading and the amount of wheel rotation. In a preferred embodiment, the heading is determined with reference to the Earth's magnetic field by disposing magnetic sensors in or on the object. Error correction and position reset procedures may be implemented to reduce accumulated navigational error. In preferred embodiments, some or all of the navigation system is disposed within a wheel of the object. In certain embodiments, the navigation system determines whether the object has exited a confinement area and activates an anti-theft system such as an alarm or a wheel locking mechanism. The navigation system can be configured to communicate with external markers and/or RF transmitters. In some embodiments, the markers comprise magnetic elements arranged to produce a magnetic signal indicating a direction or other suitable information.

Abstract: Various embodiments of a system for tracking and/or controlling wheeled vehicles (such as shopping carts), are described. In some embodiments, the system includes an RFID tag on the cart and an RFID reader device external to the cart. The tag can receive an interrogation signal from the reader and reply with a response signal. In various embodiments, the reader or a central control unit can perform various calculations based on the response signal, such as generating a received signal strength indication (RSSI) value. In some embodiments, based on the RSSI value or otherwise, the reader can send a command signal to the tag to take an action, such as to engage a brake mechanism.
