Abstract
Abstract A forensic sample and tracking system includes a computer system which operates a data base and a read/write station. The assignment of an identifier in the data base and an identification code to be printed on a sample bottle label are coordinated by the computer. An identification code can then be read for verification after it is written. This permits automated verifying of identification codes in a heretofore unavailable manner. The read/write station makes use of an inexpensive, reliable and compact thermal ink jet print head so that a field computer and read/write station can be taken to sample collection sites. The effective linear resolution of the identification code is enhanced using a two-track bar code.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
109 words
A system comprising: a write station; and computer means for receiving, processing, storing and transmitting data and commands, said computer means including: data base means for storing descriptive sample data in association with a sample identifier referable to a sample in a sample container, access means for sending data to be encoded and written by said write station, and processor means, coupled to said data base means and said access means for causing data referable to said sample identifier to be sent via said access means to said write station so that said write station writes a sample identificatiion code referable to said sample identifier on said sample container.
Claim 2
Independent Claim
109 words
A system comprising: a write station; and computer means for receiving, processing, storing and transmitting data and commands, said computer means including: data base means for storing descriptive sample data in association with a sample identifier referable to a sample in a sample container, access means for sending data to be encoded and written by said write station, and processor means, coupled to said data base means and said access means for causing data referable to said sample identifier to be sent via said access means to said write station so that said write station writes a sample identificatiion code referable to said sample identifier on said sample container.
Claim 3
Dependent Claim
18 words
The system of claim 1 wherein said write station includes container receiving means for receiving a sample container.
Claim 4
Dependent Claim
36 words
The system of claim 1 wherein said write station includes a print head and rotation means for rotating said container relative to said print head as said sample identification code is being written on said container.
Claim 5
Dependent Claim
21 words
The system of claim 1 wherein said write station can write said simple identification code in a parallel-track bar code format.
Claim 6
Dependent Claim
20 words
The system of claim 1 wherein said write station includes an ink jet head for printing on said sample container.
Claim 7
Dependent Claim
21 words
The system of claim 1 wherein said write station includes a thermal ink jet head for printing on said sample container.
Claim 8
Dependent Claim
44 words
The system of claim 1 wherein said write station includes read means for reading said sample identification code so that said sample identification code can be verified against said sample identifier and so that said sample can be associated with said descriptive sample data.
Claim 9
Dependent Claim
48 words
The system of claim 7 wherein said computer means further includes an operator interface through which said descriptive sample data can be entered and placed in association with said sample identifier in said data base in conjunction with the writing of said identification code on said sample container.
Claim 10
Dependent Claim
44 words
The system of claim 7 wherein said write station includes a print head and means for rotating said sample container while said sample identification code is being written on said sample container and while said sample identification is being read from said sample container.
Claim 11
Dependent Claim
32 words
The system of claim 9 wherein said read means includes means for detecting ends of a label of said container so that said sample identification code can be written on said label.
Claim 12
Dependent Claim
33 words
The system of claim 9 wherein said print head is a thermal ink jet print head capable of printing parallel track bar code data in a single rotational cycle of said sample container.
Claim 13
Independent Claim
119 words
An apparatus comprising: receiving means for receiving a bottle with a label; an ink jet print head for printing on said label; a sensor for reading said label; rotation means for rotating said bottle relative to said print head and said sensor; interface means for receiving write and read commands and data to be printed on said label from a host computer and for sending data read from said label to said host computer; and control circuitry for controlling said print head so that printing referable to data received from said host computer is printed on said label and for controlling said sensor so that print on said label is converted into data to be transmitted to said computer.
Claim 14
Independent Claim
119 words
An apparatus comprising: receiving means for receiving a bottle with a label; an ink jet print head for printing on said label; a sensor for reading said label; rotation means for rotating said bottle relative to said print head and said sensor; interface means for receiving write and read commands and data to be printed on said label from a host computer and for sending data read from said label to said host computer; and control circuitry for controlling said print head so that printing referable to data received from said host computer is printed on said label and for controlling said sensor so that print on said label is converted into data to be transmitted to said computer.
Claim 15
Dependent Claim
16 words
The apparatus of claim 12 wherein said ink jet head is a thermal ink jet head.
Claim 16
Dependent Claim
41 words
The apparatus of claim 13 wherein said control circuitry includes verification circuitry for causing printing to be read after being written so that the data as read can be compared to the data that was to have been printed for verification.
Claim 17
Dependent Claim
27 words
The apparatus iof claim 13 wherein said control circuitry causes said print head to print parallel track bar code in a single rotation cycle of said bottle.
