Merryman holds a patent for a "Security wheel apparatus for deterring theft of manually operated shopping carts." This invention is designed to prevent unauthorized use and removal of shopping carts constructed from steel or steel-and-plastic. The apparatus works by restricting the movement of the cart wheels after a predetermined distance has been traveled. A braking device, which is fully contained within the wheel, measures the distance traveled beyond an activating point by counting the number of rotations made by the cart wheel. This count is then compared to a preprogrammed stored attribute that defines the allowable distance the cart can travel outside the shopping facility. The system is activated when the cart passes over low-frequency magnetic arrays placed at the entry and/or exit of the shopping facility.
