Currency cassette capacity monitoring and reporting
View Patent ↗An indicator, such as an alarm or warning, is generated to indicate that a document storage cassette attached to a document handling device (e.g., a currency validator) has reached a particular capacity or is approaching its full capacity.
1. A method of providing an indication of the status of a document storage cassette attached to a document acceptor that is coupled to a host machine, the method being performed by the document acceptor and comprising:
monitoring a number of documents in the cassette;
monitoring a feed-rate of documents being inserted into the cassette;
predicting when a capacity of the document storage cassette is expected to reach a specified level based on the feed-rate and the number of documents currently in the cassette; and
generating an indicator or causing a message to be sent when it is determined that the capacity of the document storage cassette is expected to reach the specified level within a specified amount of time,
wherein the indicator is in the vicinity of the document acceptor and is generated when the capacity of the document storage cassette reaches the specified level, wherein generating the indicator includes causing a blinking rate of a light source to change in accordance with a predicted amount of time until the document storage cassette reaches full capacity.
2. The method of claim 1 wherein said estimating includes estimating when the capacity of the document storage cassette is expected to reach its full capacity.
3. The method of claim 2 wherein the document acceptor is a currency validator.
4. The method of claim 1 wherein the indicator comprises a visual or audio indicator.
5. The method of claim 1 wherein the document acceptor is a currency validator.
6. The method of claim 5 wherein the method further includes determining a validity and denomination of currency documents inserted into the currency validator and directing acceptable currency documents to the cassette.
7. An apparatus comprising:
a document acceptor;
a document storage cassette attached to the document acceptor; and
a light source;
wherein the document acceptor is operable to:
monitor a number of documents in the cassette;
monitor a feed-rate of documents being inserted into the cassette;
predict when a capacity of the document storage cassette is expected to reach a specified level based on the feed-rate and the number of documents currently in the cassette; and
generate a signal to provide an indicator or to cause a message to be sent when it is determined that the capacity of the document storage cassette is expected to reach the specified level within a specified amount of time;
wherein the indicator is in the vicinity of the document acceptor and is generated when the capacity of the document storage cassette reaches the specified level; and
wherein the signal causes a blinking rate of the light source to change in accordance with a predicted amount of time until the document storage cassette reaches full capacity.
8. The apparatus of claim 7 wherein the document acceptor is operable to estimate when the capacity of the document storage cassette is expected to reach its full capacity.
9. The apparatus of claim 8 wherein the document acceptor is a currency validator.
10. The apparatus of claim 7 wherein the indicator comprises a visual or audio indicator.
11. The apparatus of claim 7 wherein the document acceptor is a currency validator.
12. The apparatus of claim 11 wherein the document acceptor is further operable to determine a validity and denomination of currency documents inserted into the currency validator and to direct acceptable currency documents to the document storage cassette.
13. The apparatus of claim 7 wherein the document acceptor is operable to re-determine the feed rate on a fixed periodic basis.
14. The apparatus of claim 7 wherein the document acceptor is operable to monitor the feed rate of documents based on a number of stack cycles that occurs during a specified period of time.
15. The apparatus of claim 7 wherein the document acceptor is operable to monitor a number of documents stored in the cassette based on values of motor current.
16. A method of providing an indication of the status of a document storage cassette attached to a document acceptor that is coupled to a host machine, each step in the method being performed by at least one of the host machine or the document acceptor, the method comprising:
monitoring a number of documents in the cassette;
monitoring a feed-rate of documents being inserted into the cassette;
predicting when a capacity of the document storage cassette is expected to reach a specified level based on the feed-rate and the number of documents currently in the cassette; and
generating an indicator or causing a message to be sent when it is determined that the capacity of the document storage cassette is expected to reach the specified level within a specified amount of time;
wherein the indicator in the vicinity of the document acceptor and is generated when the capacity of the document storage cassette reaches the specified level wherein generating the indicator includes causing a blinking rate of a light source to change in accordance with a predicted amount of time until the document storage cassette reaches full capacity.
17. The method of claim 16 wherein said estimating includes estimating when the capacity of the document storage cassette is expected to reach its full capacity.
18. The method of claim 16 wherein the indicator comprises a visual or audio indicator.
19. The method of claim 16 wherein the document acceptor is a currency validator.
