Description

(54) INTERNALLY READABLE IDENTIFYING TAG (71) We, KEITH BARTLETT JEFFERTS and ELAINE RYAh- JEFFERTS, both citizens of the United States of America of Box 363, Shaw Island, Washington, United States of America, do hereby declare the invention, fqr which we pray that a patent may be granted to us and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention pertains generally to a method of and means for identifying nonmetallic objects, the means comprising an internally readable identifying tag including identifying indicia readily readable without removing it from the object sought to be identified.

In my earlier United States Patent No.

3,545,405 issued on December 8, 1970, there is described an apparatus for investigating the migratory habits of maco-organisms and more specifically one wherein the identifying tag contains along the surface thereof coded information. This coded information is in the form of a predetermined pattern which is imparted on the surface of the body by a high energy heat source such as by focusing laser pulses in a predetermined pattern on the surface of the body.

Although this particular identifying tag has been highly successful in its usage, certain instances exist where a more desirable form of identifying tag might be utilized.

The identifying tag described in my earlier issued patent has been used extensively in conjunction with investigating the migratory habits of Pacific Coast salmon.

When such an identifying tag is applied to investigating the migratory habits of Atlantic Coast salmon certain drawbacks have been encountered. For instance, in the case of the identifying tag described in my earlier patent it has been necessary to excise the implanted tag before decoding could be accomplished. In other words, removal of the tag from the salmon is necessary in order to properly decode the information contained thereon. In the case of Atlantic Coast salmon, where generally only a limited quantity are recovered, this requires destruction and loss of the specimen which is disadvantageous. Also, there are certain other instances wherein a tag which could be read, i.e. the information thereon decoded, while still within the body of the object is advantageous and desirable. By the means disclosed herein, such a system is provided which allows for all the advantages of my previously disclosed system and yet which does not necessitate removal of the identifying tag in order to obtain the coded information imparted thereon.

Briefly stated the present invention provides a method of identifying non-metallic objects by means of X-ray equipment which comprises the steps of: forming a unitary metallic cylindrical member having a length significantly greater than the diameter thereof; cutting a plurality of grooves in a predetermined pattern spaced from one another and extending about the circumference of said cylindrical member; implanting said cut cylindrical member into a non-metallic object; and identifying said member implanted in the non-metallic object by decoding the shape and arrangement of said member and said grooves utilizing X-ray equipment while said member is implanted in the nonmetallic object.

The invention also provides an identifying tag which is adapted for use in the method of the invention, the tag being adapted for implanting in the nonmetallic object and being adapted to be identified by means of X-ray equipment while remaining implanted within the object. The tag is in the form of a metallic cylindrical member which has a length significantly greater than the diameter thereof. A plurality of cut grooves are spaced from one another and extend about the circumference of the cylindrical member such that in profile, each of the grooves is readily identifiable by means of X-ray equipment. Thus, identification may be made while the tag remains implanted in the non-metallic object.

The method, in one embodiment, is particularly suitable for use in investigating the migratory habits of fish. In this particular embodiment, the cylindrical metallic body of the tag is of a size approximately 0.010" in diameter and has a length of at least 0.040". Such a size and length has been found particularly suitable for implanting within the body of the fish. The cylindrical body includes a plurality of cut grooves spaced from one another, with the grooves being 0.005" in diameter. The grooves are spaced from one another and extend about the circumference of the cylindrical member such that in profile, they are readily identifiable by means of X-ray equipment. In this manner, the identifying tag of this invention is provided with sufficient coded information so as to allow the object within which the tag is implanted to be identified. Moreover, the identification may readily be accomplished while the tag remains implanted within the object thus, eliminating the necessity for excising the tag prior to decoding.

An embodiment of the invention will now be described by way of example with reference to the accompanying drawings, in which: Figure 1 is a perspective view of an identifying tag in conformance with the invention; Figure 2 is an elevation view of a fish having the identifying tag of this invention implanted therein; and Figure 3 is an elevation view of the identifying tag of Figure 1 illustrating its shape in profile.

With reference to the drawings, the identifying tag indicated generally at 10 has its size dictated by the information density which may be successfully decoded with the X-ray technique. That density is such that in the case of fish, the use of three different lengths of tags in the system is preferred, all made of the same 0.010" diameter stainless steel wire. Tags of lengths of 0.040", 0.060", and 0.080" are preferred to be used simultaneously in the system and have the following information capacities. The smallest size tag has the capacity for 64 different numbers, the intermediate length 1,024 different numbers, and the longest 16.384.

This information capacity is provided on the identifying tag 10 by means of a plurality of grooves 11 spaced from one another. The grooves spaced around the periphery of the identifying tag 10 are located at predetermined positions and allow for the interpreting of the presence or absence of a ring at a given position as a binary number, 1 or 0 respectively. The ring spacing chosen is half of the wire diameter, i.e. 0.005". Two positions are reserved for an index bar which defines the reading direction and starting point with the remaining positions available as the number.

E.g., the 0.040" tag has 8 positions on its length, two reserved, 6 available for data.

Since each position can have either of two values, ring or no ring, interrupted as 1 or 0, the data capacity is 26 or 64 combinations. Similarly, for the tags having a greater length, the data capacity is increased as indicated previously.

The spaced grooves 11 are in ring form having a 0.005" diameter. The grooves are preferably cut by means of rotary spark discharge machinery wherein the grooves are formed by spark erosion of the wire surface. Alternatively, the grooves may be cut by means of a conventional diamond or carbide tool. The grooves 11 might also take a square or triangular shape which shape is such that it is readily identifiable when viewed in profile.

Once the tag is coded in accordance with the predetermined relationship, it is Implanted into the snout or head portion of the salmon. This is illustrated in FIG. 2.

Successful implantation of this nature might be best accomplished by employing the implanting machine disclosed in my earlier U.S. Patent 3,820, 545 issued on June 28, 1974. The identifying tag 10 is preferably fabricated of type 302 stainless steel. This material has been found to have the requisite magnetic characteristics for detec- tion so as to make a preliminary determination that the recovered fish has an implanted identifying tag. Subsequently when the fish has been recovered and it being determined as having an identifying tag 10 implanted therein, a portable X-ray unit may be employed and the identifying tag may be viewed while remaining within the body of the fish. In profile, the identifying tag will appear as depicted in FIG. 3 and the particular grouping of grooves may be readily ascertained and the history of the fish and its migratory habits may then be determined.

In addition to the utility of this invention in conjunction with micro-organisms as described, it has also been found that numerous problems exist in other areas where such identifying tags might also be used to advantage. For instance, manufacturers of wood products have a need to determine whether or not a certain product is one of its own at some later date.

Frequently, the question arises many years later as to the identity of the manufacturer of a certain component utilized in the structure of a building. Under some present practices, manufacturers of laminated beams inscribe identifying marks on the ends of the beam or elsewhere for the purposes of later identification. However, such a system has proven inadequate in that the ends are frequently cut off or destroyed during con destruction. Even when this does not occur, these identifying marks generally cannot be located and read without at least partially dismantling the structure and removing the particular beam in question. Identification in such instances might however, be made without these prior art difficulties by utilizing the means disclosed herein, By following the teachings disclosed herein. under such circumstances, the tags are fabricated in a slightly larger size than those heretofore described and include cut grooves shaped and formed generally in the same manner previously described. For a laminated wooden beam, such identifying tag is preferably in the form of a short nail which is ultimately nailed and thus embedded into the beam and if necessary, the wooden beam can later be idtnified by means of the coded tag or nail embedded therein. Preferably, the nail is of a size of approximately 0.125" in diameter and approximately 1.5 to 2.0 inches long. The grooves are cut and located in the manner previously described to thus incorpohate the coded information onto the nail. For this size nail, the grooves are preferably a 0.025 ring or square type groove. The nail type tag may then be embedded in the laminated beam by nailing in the conventional manner generally at a predetermined location, for instance, one-third the distance from the end of the beam. Thereafter, when it becomes necessary to identify the beam, the decoding takes place while the nail or tag remains within the beam by utilizing a portable X-ray machine. Thus, the utility of this invention encompasses numerous non-metallic objects into which the tag or nail might be embedded without causing destruction of the particular object. It is therefore readily seen, that by utilizing the identifying tag as disclosed herein, products might later be identified simply by subjecting them to an X-ray viewing and then decoding the particular information on the identifying tag or nail contained therein.

Other modifications and variations of the invention as hereinbefore set forth may be made without departing from the scope of the invention as defined in the appended
