Claim Text:
1. A shopping cart wheel comprising: a non-rotating component; a rotating component configured to rotate relative to the non-rotating component unless the shopping cart wheel is in a braking configuration where a moveable interposer is in a position between at least a portion of the rotating component and at least a portion of the non-rotating component preventing the rotating component from rotating relative to the non-rotating component; electronics configured to place the shopping cart wheel in the braking configuration in response to a wireless signal by allowing the moveable interposer to move to the position in response to the wireless signal; a wheel hub; and a clutch mechanism between the rotating component and the wheel hub, the clutch mechanism providing friction between the wheel hub and the rotating component such that the wheel hub can rotate relative to the rotating component only when a force between the wheel hub and the rotating component exceeds the friction.
