Abstract

A monitoring system for developing information data, for use in association with an opening that provides access for removal by a customer of articles stored in an article storage area. In one embodiment, the monitoring system includes a beam forming device adapted to be arranged about the perimeter of the opening so as to form at least one radiation beam that spans the opening. The radiation beam has a position with respect to the opening that is sufficient to detect manual removal by the customer of one or more of the articles from inside the article storage area, by the article and hand of the customer causing a temporary blockage of at least a portion of the radiation beam as the article and hand of the customer pass through the opening. A processing circuit coupled to the beam forming device senses the blockage of the radiation beam, and in response to the sensing, develops the information data.

Claims

1. A monitoring system for developing information data, for use in association with an opening that provides access for manual removal by a customer of articles stored in an article storage area, said monitoring system including:

13. The monitoring system of claims 1, 2 or 3, further including a thermal barrier positioned across said opening so as to provide a thermal separation between the environment where the articles are stored in said storage area, and said beam forming device.

14. The monitoring system of claim 13, wherein said thermal barrier comprises a plurality of flexible fingers which are relatively easily deflected so as to allow the passage of the customers hand and/or an article therethrough, yet have a normal, unflexed, position which substantially prevents air flow into and out of the inside of the article storage area.

9.

2. A monitoring system for developing information data, for use in association with an opening that provides access for manual removal by a customer of articles stored in an article storage area, comprising:

a beam forming device adapted to be arranged about the perimeter of said opening so as to form at least one radiation beam that spans said opening, said radiation beam having a position with respect to said opening that is sufficient to detect manual removal by said customer of one or more of said articles from inside the article storage area, by at least one of said article and said hand of said customer causing a temporary blockage of at least a portion of the radiation beam as said article and hand of said customer pass through said opening; and

a processing circuit coupled to the beam forming device for sensing the blockage of said radiation beam, and in response to said sensing developing said information data.

3. The monitoring system of claim 2, where the information data is representative of the inventory condition of the article storage area from which the article was removed.

4. The monitoring system of claim 2, adapted for use in a manual or automatic article dispenser, wherein:

the beam forming device forms a matrix of a plurality of radiation beams that span said opening, said matrix of radiation beams having a beam density across said opening sufficient to prevent an article from being removed from inside the article storage area and to pass through said opening without said article causing a blockage of the radiation in at least two of said beams;

said processing circuit is coupled to the radiation beam matrix forming device for sensing the blocking of said radiation beams, and in response to said sensing, developing information data that identifies the storage position in the article storage area from which the article was removed.

5. The monitoring system of claim 4, wherein said opening is generally rectangular, and has first and second opposed pairs of sides, and the beam forming device includes on each side of said opposed pairs, electronic a plurality of devices, selective ones of which either transmit or receive radiation.

6. The monitoring system of claim 4, wherein the beam forming device includes a plurality of radiation transmitters and a corresponding plurality of radiation receivers.

7. The monitoring system of claim 4, wherein one of each side of said opposed pairs of sides of said beam forming device includes only electronic devices that transmit radiation and the other of each side of said opposed pairs of sides of said beam forming device includes only electronic devices that receive radiation.

8. The monitoring system of claim 4, wherein the beam forming device is adapted to be a retrofitted part to be affixed about the opening to the article storage area of a self-serve merchandiser.

10. The monitoring system of paragraph 9, wherein said storage devices are a plurality of article storage baskets.

11. The monitoring system of claim 4, wherein said beam forming device is adapted to be used in an article storage area having a cooling means which keeps the articles stored therein in a cold environment.

12. The monitoring system of claim 4, wherein said beam forming device includes at least one heating device which heats said radiation transmitters and/or receivers in order to inhibit the formation of condensation or frost thereon.

15. The monitoring system of claim 4, wherein said beam forming device also includes a sensor coupled to said processing circuit for developing information data representative of the opening of an access door, said access door normally positioned over said opening so as to substantially shield the inside of said article storage area from the local environment.

16. The monitoring system of claim 15, further including an alarm signal, developed in responsive to the sensing of said access door being in an opened position for greater than an preset period of time.

17. The monitoring system of claim 16, wherein said processing circuit develops said alarm signal, said alarm signal being used to activate an alarm that is located in close proximity to said article storage area.

18. The monitoring system of claim 4, wherein said beam forming device also includes a sensor coupled to said processing circuit for developing information data representative of temperature inside of said article storage area.

19. The monitoring system of claim 4, wherein said beam forming device also includes one or more sensors coupled to said processing circuit for developing information data representative of one or more operative conditions of said article storage area.
