Dispensary embossed character container labeling
First Claim
1. In a dispenser having storage stations each containing at least one container, wherein each said container has a substantially planar outside surface with an embossed character therein and a shape and size different from that of a plurality of other said containers in respective said storage stations, a method comprising:
- for each said container;
retrieving the container from the corresponding said storage station;
moving the container to an inspection station;
directing first light in a first direction across the embossed character to illuminate first parts of the embossed character;
recording first image data representing the embossed character illuminated by the first light;
directing second light in a second direction across the embossed character to illuminate second parts of the embossed character;
recording second image data representing the embossed character illuminated by the second light;
combining the first image data and the second image data to produce combined image data;
comparing the combined image data to reference data;
on the basis of the comparison, identifying the embossed character;
applying the identified embossed character as an identifying label to the container;
retrieving the labeled container from the inspection station; and
moving the labeled container to one of the storage stations;
receiving, from a network, an identifier;
applying a label to the one said labeled container in one said storage station bearing the identifying label that corresponds to the identifier; and
dispensing the labeled container to a user of the dispenser.

Abstract
In a method and apparatus for identifying an embossed character, light of one color is directed in one direction across the embossed character to illuminate certain character parts and light of another color is directed in another direction across the embossed character to illuminate other character parts. Image data for the two colors are captured and are subjected to separate image processing to detect edges highlighted by the directed light. The processed images are combined and supplemented with OCR analysis before being compared with predicted characters. Based on the comparison, a determination is made as to the probable identity of the character.

13. In a dispenser having storage stations each containing at least one container, wherein each said container has a substantially planar outside surface with an embossed character therein and a shape and size different from that of a plurality of other said containers in respective said storage stations, a system comprising:
-
for each container in the dispenser; a mover module operable to; retrieve the container from the corresponding said storage station; and move the container to an inspection station inside the dispenser; an inspection module in the inspection station inside the dispenser having a lighting sub-system for; directing first light in a first direction across the embossed character to illuminate first parts of the embossed character; and directing second light in a second direction across the embossed character to illuminate second parts of the embossed character; an imaging sub-system for recording; first image data representing the embossed character illuminated by the first light; and
-second image data representing the embossed character illuminated by the second light; anda processing sub-system having a filtering module to filter; the first image data to obtain first edge data corresponding to the light directed in the first direction; and the second image data to obtain second edge data corresponding to the light directed in the second direction; a combining module for combining the first image data and the second image data to produce combined image data; and an identification module to identify the embossed character from the combined image data; a labeling module operable to apply the identified embossed character as an identifying label to the container; a first retrieving module operable to retrieve the labeled container from the inspection station inside the dispenser; and a second mover module operable to move the labeled container to one of the storage stations inside the dispenser; a receiver module operable to receive, from a network, an identifier; a picking module operable to pick one said labeled container in one said storage station inside the dispenser bearing the identifying label that corresponds to the identifier; a printing and applying module operable to print and apply to the picked container, a label corresponding to; the identifying label; and the identifier; and a dispensing module operable to dispense the labeled picked container to a user of the dispenser. - View Dependent Claims (14, 15, 16, 17, 18)

19. For a plurality of dispensers in communication with a communication network, each said dispenser having storage stations, each said storage station having therein at least one container, each said container bearing embossed characters, a method comprising:
-
for each said container in each said dispenser; directing a plurality of lights, each being in a different direction, across the embossed characters to illuminate a corresponding part of the embossed characters; recording, for each said light, corresponding image data representing the embossed characters illuminated by the light; combining the recorded image data for each said light to produce combined image data; comparing the combined image data to reference data; on the basis of the comparison, identifying the embossed characters; sending the identified embossed characters in a transmission addressed for delivery to a location on the communications network; receiving, in response to the sent transmission, a transmission from an address on the communication network and containing modified identified embossed characters corresponding to the identified embossed characters in the sent transmission; and applying an identifying label to the container having the modified identified embossed characters; and for one said dispenser; receiving information containing an identifier from the communications network; applying a label to one said container that bears the identifying label that corresponds to the identifier, wherein the label corresponds to; the identifying label; and the identifier; and dispensing the labeled container to a user of the one said dispenser. - View Dependent Claims (20)
