Abstract
Abstract A system for identifying a moving railway vehicle or any other object upon which is fastened an identification label having a number of vertical columns of light retransmitting medium, each column representing a digit number obtained by coding the column by insertion of a metal plate in front of the column. A wayside light transmitter/receiver unit provides a source of light beam directd toward the path of travel of the vehicle and also provides a light beam receiver responsive to retransmitted light signals from the label. The receiver decodes these signals using a control means such as a microprocessor and transmits all pertinent information in digital form to other data processing equipment employed by the user.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
271 words
A system for identifying objects moving along a path past a stationary location comprising: means adapted to be placed at said location for defining a source of a radiation beam, said defining means being operable to direct a radiation beam in the form in a generally vertical column across the path of travel of the moving object when the source is at said location; a label adapted to be mounted on an object moveable along said path for identifying the same, the label having at least a pair of side-by-side radiation receiving and transmitting columns alignable across the path of the radiation beam when the label is on the object and when the source is at said location, each column having means selectively located thereon for blocking at least a portion of the light beam to thereby define a radiation entrance port and a radiation exit port for the column, each column further having radiation transmitting means therein for connecting the entrance and exit ports thereof so that a radiation beam entering the entrance port can pass into the column and exit therefrom at the exit ports; and radiation receiving means adapted to be placed at said location adjacent to said radiation source for receiving the radiation beam leaving each column through the exit port thereof, said radiation receiving means being operable to generate electronic signals in response to the radiation transmitted from each column, whereby the locations of the entrance and exit ports relative to a specific reference point on the corresponding column, provide a coded identification for each object to distinguish it from other objects moving past the location.
Claim 2
Independent Claim
271 words
A system for identifying objects moving along a path past a stationary location comprising: means adapted to be placed at said location for defining a source of a radiation beam, said defining means being operable to direct a radiation beam in the form in a generally vertical column across the path of travel of the moving object when the source is at said location; a label adapted to be mounted on an object moveable along said path for identifying the same, the label having at least a pair of side-by-side radiation receiving and transmitting columns alignable across the path of the radiation beam when the label is on the object and when the source is at said location, each column having means selectively located thereon for blocking at least a portion of the light beam to thereby define a radiation entrance port and a radiation exit port for the column, each column further having radiation transmitting means therein for connecting the entrance and exit ports thereof so that a radiation beam entering the entrance port can pass into the column and exit therefrom at the exit ports; and radiation receiving means adapted to be placed at said location adjacent to said radiation source for receiving the radiation beam leaving each column through the exit port thereof, said radiation receiving means being operable to generate electronic signals in response to the radiation transmitted from each column, whereby the locations of the entrance and exit ports relative to a specific reference point on the corresponding column, provide a coded identification for each object to distinguish it from other objects moving past the location.
Claim 3
Dependent Claim
20 words
A system as set forth in claim 1, wherein the label has a plurality of side-by-side prisms defining respective columns.
Claim 4
Dependent Claim
41 words
A system as set forth in claim 2, wherein each prism has a front face, said blocking means including an opaque plate coupled to the face in at least partial blocking relationship to radiation directed from the source toward the column.
Claim 5
Dependent Claim
38 words
A system as set forth in claim 1, wherein said label is formed from a plurality of fiber optics bundles, each bundle having a pair of opposed end faces permitting radiation to enter and leave the bundle, respectively.
Claim 6
Dependent Claim
27 words
A system as set forth in claim 4, wherein the fiber optics bundles are substantially U-shaped segments arranged in a vertical stack to define a respective column.
Claim 7
Dependent Claim
29 words
A system as set forth in claim 4, wherein said blocking means comprises a plate for blocking the end faces of at least certain of the fiber optics bundles.
Claim 8
Dependent Claim
38 words
A system as set forth in claim 1, wherein said light receiving means includes a column of photosensors, the height of the photosensors column being at least substantially equal to the height of the columns of the labels.
Claim 9
Dependent Claim
15 words
A system as set forth in claim 1, wherein said source is an infra-red source.
Claim 10
Dependent Claim
44 words
A system as set forth in claim 1, wherein said label has a plurality of columns, one of the columns being at one end of the label and being free of said blocking means, each of the other columns having said blocking means thereon.
Claim 11
Dependent Claim
215 words
In a system for identifying objects moving along a path past a stationary location having a radiation source operable to direct a radiation beam across the path and radiation receiving means for receiving radiation transmitted from the object and converting the transmitted radiation to electronic signals, the improvement comprising: a lable adapted to be mounted on an object moveable along said path for identifying the same, the label having at least a pair of side-by-side radiation receiving and transmitting columns alignable across the path of the radiation beam when the label is on the object, each column having means for blocking at least a portion of the light beam to thereby define a radiation entrance port and a radiation exit port for the column, each column further having radiation transmitting means therein for connecting the entrance and exit ports so that a radiation beam entering the entrance port can pass into the column and exit therefrom at the exit ports to said receiving means at said location, whereby the electronic signals will be generated by said receiving means and the location of the entrance and exit ports relative to a specific reference point on the corresponding column will provide a coded identification for each object to distinguish it from other objects moving past the location.
