Abstract: Various systems for monitoring wheeled vehicles (such as shopping carts) are disclosed. The system can include an RF antenna unit that is buried and is configured for bi-directional communication with the electronics on the cart. In some embodiments, the antenna comprises a plurality of transmitters, which can emit synchronized signals. In some embodiments, the antenna comprises a radiating cable, which can emit a signal along some, substantially all, or all of its length.

Abstract: A system for controlling shopping carts usage in the vicinity of a parking lot, the system comprising: a device that repeatedly transmits a lock command from a directional antenna (282), said directional antenna mounted above ground and angled downward to create a lock zone (286) in which shopping cart use is restricted, said lock zone encompassing an exit area associated with the parking lot; and a plurality of shopping carts, each shopping cart comprising a brake mechanism, and comprising an RF communication circuit that is responsive to the lock command by activating the brake mechanism.

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: Various loop antenna fixture embodiments are disclosed. The fixture can be configured to removably attach with other fixtures, thus changing the overall dimensions of an antenna wrapped around the periphery of the fixture or fixtures. Advantageously, after the antenna is wrapped around the fixture(s) to form an assembly, the entire assembly can be removed and installed without the requirement of removing the antenna from the fixture(s).
