Abstract
Abstract A method for processing the reading of bar code tags or labels in which a bar code scanner reads a plurality of bar code tags in the field of view of the scanner while in a stationary position generating tag representation for each tag read comprising the steps of storing in a first storage unit the first tag representation, comparing each succeeding tag representation with the first tag representation and generating a count representing the number of times the same tag read was read for use in processing the bar code tags in the minimum amount of time.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
A method for processing the reading of a plurality of bar-code tags or labels in which a bar-code scanner reads each of a number of bar-code tags located in the field of view of the scanner at the same time while in a stationary position generating a tag representation for each tag read, comprising the steps of: storing in a first storage unit data representing the first tag representation; generating a count representing the first tag read; comparing each succeeding tag representation with the first tag representation; increasing the count each time a tag representation is found to be the same as the first tag representation; and storing the count generated in a second storage unit indicating the number of readings of the same tag by the scanner for use in processing all of the tag representations.
Claim 2
Independent Claim
137 words
A method for processing the reading of a plurality of bar-code tags or labels in which a bar-code scanner reads each of a number of bar-code tags located in the field of view of the scanner at the same time while in a stationary position generating a tag representation for each tag read, comprising the steps of: storing in a first storage unit data representing the first tag representation; generating a count representing the first tag read; comparing each succeeding tag representation with the first tag representation; increasing the count each time a tag representation is found to be the same as the first tag representation; and storing the count generated in a second storage unit indicating the number of readings of the same tag by the scanner for use in processing all of the tag representations.
Claim 3
Dependent Claim
28 words
The method of claim 1 which further includes the stop of starting a timeout period to run upon storing the first tag representation in the first storage unit.
Claim 4
Dependent Claim
37 words
The method of claim 1 which further includes the stop of storing second tag representation in a second storage unit when the second tag representation is found not to be the same as the first tag representation.
Claim 5
Dependent Claim
29 words
The method of claim 3 which further includes the stop of starting a second timeout period to run upon storing the second tag representation in the second storage unit.
Claim 6
Dependent Claim
39 words
The method of claim 2 which further includes the step of storing data representing the timeout period generated and clearing the timeout period when a subsequent tag representation is found to be the same as the first tag representation.
Claim 7
Dependent Claim
27 words
The method of claim 5 which further includes the step of detecting if a timeout period has expired when no tag representation is generated by the scanner.
Claim 8
Dependent Claim
38 words
The method of claim 1 which further includes the step of storing in a third storage unit time data indicating the time the same tag was last read to increase the time of reading the bar code tags.
