  • Patent number: 7565222
    Abstract: A monitor and method for reasonable confirmation of a vend from a vending machine includes a set of optical emitters positionable on one side of a dispensing area and a set of optical detectors, adapted to sense the optical energy of the emitters, positioned on an opposite side of the dispensing area. The emitters are spaced apart from each other and mounted on a supporting structure that can be installed on the one side of the dispensing area in a vending machine. The detectors similarly are spaced from one another on a supporting structure that can be installed on an opposite side of the dispensing area. A controller operates the emitters to individually turn on and off in a predetermined sequence. The controller checks for falsing of any detector during the off periods and monitors if any detector is blocked during the on periods. Upon sensed falsing or blockage, the controller generates an output signal.

  • Patent number: 6302292
    Abstract: A storage, display and dispensing apparatus for tickets of various sizes that accounts for the tickets dispensed during a selected time period. The dispensing apparatus includes a bin housing for storing a pack of tickets, a ticket dispensing assembly through which the tickets are dispensed and includes a friction wheel assembly that is actuated as tickets passed through the tear bar assembly so that a count of such tickets is provided. A piezo electric sensing element is also employed to sense perforations between the tickets and to reset the friction wheel assembly count as a result thereof.
