Abstract
Abstract A method and apparatus for testing bar code reader devices. A computer is programmed to receive data indicative of output signals of input devices for reading symbologies and to produce signals representative of those corresponding to the output of an input device. The computer then sends these representative signals to a subject bar code reader and receives the resulting signals produced by the reader. The computer also compares the received resulting signals with the representative signals to determine any differences. If the differences are judged to be significant, the computer produces an indicative signal.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
122 words
A method for testing a subject symbology reader against a standard symbology reader, comprising the steps of: (a) producing test input signals substantially identical to predetermined input signals produced by symbology input device in response to the input of a predetermined symbology, the predetermined input signals being known to cause the standard symbology reader connected to the symbology input device to produce predetermined desired response signals; (b) directing the test input signals to the subject symbology reader; (c) recording the test response signals that the test input signals cause the subject symbology reader to produce; and (d) comparing the predetermined response signals and the test response signals to determine whether the test response signals are substantially identical to the predetermined response signals.
Claim 2
Independent Claim
122 words
A method for testing a subject symbology reader against a standard symbology reader, comprising the steps of: (a) producing test input signals substantially identical to predetermined input signals produced by symbology input device in response to the input of a predetermined symbology, the predetermined input signals being known to cause the standard symbology reader connected to the symbology input device to produce predetermined desired response signals; (b) directing the test input signals to the subject symbology reader; (c) recording the test response signals that the test input signals cause the subject symbology reader to produce; and (d) comparing the predetermined response signals and the test response signals to determine whether the test response signals are substantially identical to the predetermined response signals.
Claim 3
Dependent Claim
42 words
The method of claim 1 wherein step (a) comprises programming a computer to produce the test input signals on an output port of the computer and wherein step (b) comprises connecting the output port of the computer to the subject symbology reader.

Claim 6
Dependent Claim
31 words
The method of claim 1, further comprising the step of producing an indicator signal when the response signals of the subject symbology reader are significantly different from the predetermined response signals.
Claim 7
Dependent Claim
124 words
Apparatus for testing a subject symbology reader against a standard symbology reader, comprising: source means for producing test input signals substantially identical to predetermined input signals produced by a symbology input device in response to the input of a predetermined symbology, the predetermined input signals being known to cause the standard symbology reader connected to the symbology input device to produce predetermined desired response signals; means for directing the test input signals to the subject symbology reader; means for recording the test response signals that the test input signals cause the subject symbology reader to produce; and means for comparing the predetermined response signals and the test response signals to determine whether the test response signals are substantially identical to the predetermined response signals.
Claim 8
Dependent Claim
124 words
Apparatus for testing a subject symbology reader against a standard symbology reader, comprising: source means for producing test input signals substantially identical to predetermined input signals produced by a symbology input device in response to the input of a predetermined symbology, the predetermined input signals being known to cause the standard symbology reader connected to the symbology input device to produce predetermined desired response signals; means for directing the test input signals to the subject symbology reader; means for recording the test response signals that the test input signals cause the subject symbology reader to produce; and means for comparing the predetermined response signals and the test response signals to determine whether the test response signals are substantially identical to the predetermined response signals.
