    摘要： 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.

    摘要： A power management system is disclosed. Embodiments of the power management system may be configured for use with an electric generator that produces AC or DC voltage from an energy source, which may be intermittent or fluctuating. One embodiment of the power management system includes an energy storage reservoir configured to be electrically coupled to the electric generator. The energy storage reservoir includes at least one ultracapacitor and at least one rechargeable battery. The power management system also includes an electronic controller configured to control storage in the reservoir of energy generated by the electric generator and to control power usage from the reservoir and the generator. The electronic controller is configured to control energy storage and power usage in response to one or more control signals.
