Abstract: A method of monitoring shopping cart usage. The method involves generating shopping cart event data via two-way radio frequency (RF) communications with each of a plurality of shopping carts associated with a store, the event data including information reflective of zone entry events detected by particular shopping carts, each zone entry event representing entry of a particular shopping cart into a particular zone of a plurality of zones associated with the store, the zone entry events detected by the corresponding shopping carts based on transmissions received by the shopping carts from corresponding antennas mounted in a monitoring area associated with the store, the shopping cart event data additionally including battery level data reported by the shopping carts, the battery level data reflective of battery levels of batteries included in wheel assemblies of the shopping carts. The method further involves aggregating the shopping cart event data associated with the plurality of shopping carts in a data repository, and programmatically analyzing the aggregated shopping cart event data to generate statistical information regarding the shopping carts. The method involves, via circuitry included in the wheel assemblies of the shopping carts, generating received signal strength measurements based on the transmissions, and using the received signal strength measurements to detect the zone entry events.

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: 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: An anti-theft system for an object having a wheel including a navigation system comprising a processor, the navigation system configured to receive a start navigation signal from an exit marker and a stop navigation signal from an entrance marker. The navigation system is operable to determine a relative position of the object with respect to a confinement boundary. The anti-theft system includes a brake system operable to provide a braking force to the wheel and responsive to a braking signal from the navigation system. The navigation system is operable to provide the braking signal to the brake system if the relative position satisfies a first predetermined condition, wherein the first predetermined condition occurs after the navigation system has received the start navigation signal.

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.
