Abstract
Abstract In an automatic identification system for reading a remote label containing information in the form of a plurality of vertically arrayed horizontal stripes which may include wide stripes and narrow stripes, a stripe width determining circuit which detects a stripe of known absolute width, measures the relative width of the stripe of known absolute width, stores a representation of the relative size of the stripe of known absolute width, measures the relative width of each of the other stripes, and compares the relative width of the stripe of known absolute width with the relative width of each of the other stripes to determine the absolute width of each of the other stripes.

Claim 1
Independent Claim
210 words
In an automatic reading system for reading a remote label containing coded information in the form of a plurality of stripes which may include wide stripes and narrow stripes, a stripe width determining circuit comprising: detector means for recognizing a specific code contained in a stripe whose width is known; first encounter means; a first source of clock signals occurring at a first clock rate; and first gating means for gating said clock signals at said first rate to said first counter during the interval of a stripe; second counter means; a second source of clock signals occurring at a second clock rate different than said first rate and second gating means for gating said clock signals at said second rate to said second counter during the interval of a stripe whose width is to be determined; storage means, third gating means, responsive to a recognition of said specific code by said detector means, for transferring to said storage means the count accumulated in said first counter means; and comparator means for comparing the accumulated count in said storage means with the accumulated count in said second counter means and producing a first output if the former exceeds the latter and a second output if the latter exceeds the former.

Claim 3
Dependent Claim
30 words
The stripe width determining circuit of claim 1 in which said first source of clock signals produces clock signals at a slower rate than said second source of clock signals.
Claim 4
Dependent Claim
17 words
The stripe width determining circuit of claim 1 in which said detector means recognizes a wide stripe.
Claim 5
Dependent Claim
32 words
The stripe width determining circuit of claim 1 in which said detector means includes an AND gate for recognizing the code contained in the first stripe of known width on the label.
Claim 6
Independent Claim
131 words
A method of automatically reading a remote label containing coded information in the form of a plurality of stripes which may include wide stripes and narrow stripes comprising: detecting a specific code contained in a stripe whose width is known; counting signals occurring at a first rate during the interval of a stripe; counting signals occurring at a second rate different from the first rate during the interval of a stripe; storing the first count if the stripe occurring in that interval has been recognized as the specified code contained in a stripe whose width is known; comparing the second count and the count stored to determine which is larger; and producing a first output if the second count is larger and a second output if the stored count is larger.
Claim 7
Independent Claim
131 words
A method of automatically reading a remote label containing coded information in the form of a plurality of stripes which may include wide stripes and narrow stripes comprising: detecting a specific code contained in a stripe whose width is known; counting signals occurring at a first rate during the interval of a stripe; counting signals occurring at a second rate different from the first rate during the interval of a stripe; storing the first count if the stripe occurring in that interval has been recognized as the specified code contained in a stripe whose width is known; comparing the second count and the count stored to determine which is larger; and producing a first output if the second count is larger and a second output if the stored count is larger.
