Abstract
Abstract The mold source of a bottle provided with one or more sectors spanning a circumferential zone with prism-like timing marks thereon is identified by an on-line programmed microcomputer. The bottle is identified by a laser beam and sensor. The sensor generates a series of digital pulses in response to the passage of the laser beam through the timing marks. The leading and trailing edges of the pulses are time stamped by the microcomputer. A microcomputer program identifies the mold source of the bottle based on the time stamped information. The identification of the bottle and its status are stored in the microcomputer memory. A running log of the numbers of defective and acceptable bottles produced by the mold source is printed out based on the contents of the microcomputer memory.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
173 words
A computer controlled system for identifying the mold source of a bottle provided with one or more sectors spanning a circumferential zone with prism-like timing marks thereon including a laser source for passing a laser beam through the sectors and a sensor for generating a series of digital pulses in response thereto, comprising: means for generating a series of digital clock pulses independently of said sensor pulses; means for time stamping said sensor pulses with said clock pulses and for storing the time stamp information; means for digitally computing the pulse widths and inter-pulse spacings of said sensor pulses in terms of said time stamp information. means for digitally comparing the spans of said sectors in terms of said time stamp information to said interpulse spacings of said sensor pulses; and means for digitally weighting the sensor pulses in response to said digitally comparing means to provide a digital signal representing the distribution of said timing marks on said bottle, said distribution of timing marks uniquely identifying the mold source of said bottle.
Claim 2
Dependent Claim
173 words
A computer controlled system for identifying the mold source of a bottle provided with one or more sectors spanning a circumferential zone with prism-like timing marks thereon including a laser source for passing a laser beam through the sectors and a sensor for generating a series of digital pulses in response thereto, comprising: means for generating a series of digital clock pulses independently of said sensor pulses; means for time stamping said sensor pulses with said clock pulses and for storing the time stamp information; means for digitally computing the pulse widths and inter-pulse spacings of said sensor pulses in terms of said time stamp information. means for digitally comparing the spans of said sectors in terms of said time stamp information to said interpulse spacings of said sensor pulses; and means for digitally weighting the sensor pulses in response to said digitally comparing means to provide a digital signal representing the distribution of said timing marks on said bottle, said distribution of timing marks uniquely identifying the mold source of said bottle.
Claim 3
Dependent Claim
45 words

Dependent Claim
29 words
Apparatus according to claim 2 including means for generating a status indicating that said bottle is defective independently of said means for digitally comparing said computed and predetermined numbers.
Claim 5
Dependent Claim
59 words
Apparatus according to claim 3 including first means for digitally counting the number of instances in which said computed and predetermined numbers match, second means for digitally counting the number of instances in which said computed and predetermined numbers do not match, and third means for digitally counting the number of instances in which said status signal is generated.
Claim 6
Dependent Claim
27 words
Apparatus according to claim 4 including means for storing each of said digital counts and means for printing out said digital counts for each computed digital number.

Independent Claim
156 words
A method for identifying the mold source of a bottle provided with one or more sectors spanning a circumferential zone with prisms-like timing marks thereon including passing a laser beam through the sectors and generating a series of digital sensor pulses in response thereto, comprising the steps of: generating a series of digital clock pulses independently of said sensor pulses; digitally time stamping said sensor pulses with said clock pulses and storing the time stamp information; digitally computing the pulse widths and interpulse spacings of the sensor pulses in terms of the clock pulses; digitally comparing the spans of said sectors in terms of said clock pulses to the inter-pulse spacings of said sensor pulses; and digitally weighting the sensor pulses in response to said digitally comparing step to provide a digital signal representing the distribution of said timing marks on said bottle, said distribution of timing marks uniquely identifying the mold source of said bottle.
Claim 8
Independent Claim
156 words
A method for identifying the mold source of a bottle provided with one or more sectors spanning a circumferential zone with prisms-like timing marks thereon including passing a laser beam through the sectors and generating a series of digital sensor pulses in response thereto, comprising the steps of: generating a series of digital clock pulses independently of said sensor pulses; digitally time stamping said sensor pulses with said clock pulses and storing the time stamp information; digitally computing the pulse widths and interpulse spacings of the sensor pulses in terms of the clock pulses; digitally comparing the spans of said sectors in terms of said clock pulses to the inter-pulse spacings of said sensor pulses; and digitally weighting the sensor pulses in response to said digitally comparing step to provide a digital signal representing the distribution of said timing marks on said bottle, said distribution of timing marks uniquely identifying the mold source of said bottle.
Claim 9
Dependent Claim
44 words
