1. A vending method for determining whether a product is delivered, the method comprising:
- sending a delivery signal to a product delivery system based on a customer ordering event;
monitoring a delivery path that the ordered product travels to reach a product receiving location with a monitoring system located along the delivery path to detect when the product passes through the delivery path, the monitoring system optically scanning the delivery path for product transition past the monitoring system using a plurality of light emitters and a corresponding plurality of light detectors by (a) separately activating at least one but fewer than all of the light emitters and (b) for each of the light emitters when that light emitter is activated, monitoring at least two of the light detectors; and
determining if the product was delivered to the receiving location.

Abstract
The present invention provides for a vending system wherein a monitoring system verifies that a product ordered by a vending customer is actually delivered through a delivery area to the customer. If the product ordered is unavailable either because of an out of stock situation or a blockage of the delivery path for that product, the present invention allows the customer to request a refund or order a second product. Additionally, the present invention helps to prevent theft of product from the vending system.

11. A method of enabling verification of the delivery of a ordered product in a vending machine, the method comprising:
-
providing a product delivery system for dispensing a product from a product storage position, along a delivery path to a product delivery position in response to a customer order; providing a monitoring system along the delivery path detecting when the product passes the monitoring system, the monitoring system including a plurality of light emitters and a corresponding plurality of light detectors opposite the light emitters, each light emitter, when activated, emitting light across the delivery path onto a plurality of the light detectors, wherein the emitted light from an activated light emitter is detected, unless interrupted, using two or more of the plurality of light detectors. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of monitoring operation of a vending machine comprising:
-
optically scanning a delivery path which a product ordered by a customer travels using an array of emitters on one side of the delivery path and an array of detectors on an other side of the delivery path, wherein a first emitter with the emitter array is actuated alone, a second emitter within the emitter array is actuated alone, and each remaining emitter within the emitter array, if any, is successively actuated alone until all emitters within the emitter array have been actuated, and wherein at least first and second detectors within the detector array are employed to detect light from the first emitter when the first emitter is actuated and to detect light from the second emitter when the second emitter is actuated. - View Dependent Claims (25, 26)

27. A method of enabling control based upon product delivery in a vending machine, the method comprising:
-
providing a row of light emitters; providing a row of light detectors opposite the light emitters, each light detector substantially aligned with one of the light emitters, wherein light from each light emitter, when activated, impinges upon a plurality of the light detectors; providing a controller individually and sequentially activating the light emitters in a cyclic manner; and providing logic generating a first logical signal when portions of light emitted by an activated one of the light emitters are detected at all of two or more of the light detectors and a second logical signal when at least one portion of the light emitted by the activated light emitter is not detected at at least one of the two or more light detectors, wherein the controller is adapted to operate in a calibration mode and in a monitoring mode, and wherein the controller is adapted to operate in the calibration mode prior to receipt of a customer order and switch to the monitoring mode upon receipt of the customer order.
