Abstract: A computing device retrieves a stabilized weight and a weight-based item count for one or more items to be purchased. Responsive to retrieving the stabilized weight, the computing device retrieves an image-based item count and an expected weight based on the image-based item count for the one or more items to be purchased. The computing device selects between authorizing and blocking checkout of the one or more items based on the weight-based item count, the image-based item count, the stabilized weight, and the expected weight.

Abstract: The window anti-icing/deicing apparatus and method spreads deicing agents onto the outside surface of the windshield and windows of a mobile vehicle and aircraft. The device includes deicing agents, a storage container, power supply, motor, pump, nozzles, and switching system circuitry. The device quickly provides a clear, defrosted window surface on each window prior to the time the vehicle is in motion. The system includes a container connected to a pump or a solenoid for directing the deicing agent to a suction side of the pump through an outlet in to the container. The deicing agent is supplied to a propeller and then via a distributor distributed onto targeted surfaces. Nozzles are provided for expressing the deicing agents onto surfaces. A power supply is connected to the system to operate the pump and the propeller for activating the deicing system. The system may be provided anywhere on a vehicle or an aircraft, such as trunks, roof racks, engine compartments or the like.
