Abstract: A method and apparatus for controlling a display in which the display is provided with an embedded switch with a sensor interface. The switch is adapted to switch the display between an active state and a dormant state based upon sensor input. The display is switched to an active state upon the embedded switch receiving input from the sensor of the presence of a potential viewer. The display is switched to a dormant state in the absence of input from the sensor.

Abstract: A vehicle sensing system for a drive-through retail outlet. The vehicle sensing system includes a building housing a drive-through retail outlet. The building has exterior defining walls with at least one service window. A service lane is provided which is adapted to accommodate vehicular traffic. The service lane is positioned immediately adjacent to at least one of the exterior defining walls. At least one magnetic anomaly detector is positioned along the at least one of the exterior defining walls on the inside of the building. The magnetic anomaly detector is adapted to detect vehicles in the service lane approaching the at least one service window.

Abstract: A method for order verification, the first step of which involves providing a computer processor having both data storage and computing capability. The second step involves storing data as to a weight for each of a plurality of items offered for sale in the computer processor. The third step involves inputting into the computer processor selected items that make up a customer order from the plurality of items stored in data and computing a projected total weight for the customer order. The fourth step involves assembling the selected items that make up the customer order and placing the customer order onto a weigh scale. The fifth step involves comparing an actual weight of the customer order with the projected total weight to verify the order.
