Background and Summary of the Invention
This invention relates to specific identi¬ fying indicia that can be bonded to a person's ana¬ tomy and, more particularly, to apparatus for per- forming the bonding.
Applicants are aware of the following U.S. Patents, the disclosures of which are incorporated by reference herein: 3,952,438; 3,949,233; 4,027,391; 4,208,795; 4,233,964; 4,239,261; 4,473,353; 4,557,693; 4,439,154; 4,512,744 and Re. 30,594.
This application is a continuation-in-part of United States patent application Serial No. 936,597, filed December 1, 1986, which is assigned to the same assignee as this application. United States patent application Serial No. 936,597 discloses a method of producing an element of personal identifi¬ cation. The element produced is a microdot wnich can be bonded to an individual's teetn, the microdot con¬ taining personal identifying information. while it is understood that the microdot can oe attached to a person's tooth, the attacnment must be accomplished in such a way that the microdot is permanently fixed in place and is not easily dis¬ lodged. In addition, the microdot must be so affixed that the information contained thereon is legible and readable at future dates or else the whole procedure is a waste of time and money. It is desirable to avoid obscuring of the microdot by formation of an opaque layer over the indicia contained on the micro- dot. In particular, the formation of an opaque, air inhibited layer in the adhesive used to cover the • microdot should be avoided.
Therefore, it is an object of the present invention to provide apparatus for attaching a micro- dot containing personal identifying indicia to a per- son's tooth.
It is a further object of the invention to provide apparatus which attaches the microdot per¬ manently.
Another object of the invention is to pro- vide apparatus which insures the attached microdot will be legible after attacnment so the information can be read in place at future dates.
Also, it is an object of the invention to provide apparatus which is easy to operate and rela- tively inexpensive.
Other objects and features will in part be apparent and in part pointed out hereinafter. Brief Description of the Drawings;

Description of the Preferred Embodiment Referring to the drawings, a microdot con¬ taining specific identifying indicia of a person P is to be attached to a tooth T of the person. . The microdot is prepared in accordance with the disclo¬ sure in co-pending United States Patent application 936,597, which is assigned to the same assignee as the present application. United States patent appli¬ cation Serial No. 93b,597 is incorporated Herein oy reference.
The apparatus for bonding the microdot to tne tooth is indicated generally 1 in the drawings and comprises a means 3 for fitting over the tooth and positioning the microdot adjacent to it. Since the tooth typically selected for having a microdot bound to it is an upper rear molar, the means is co - pact in size. As shown in FIGS. 3 and 4 means 3 com¬ prises a jig 5 which is generally U-snaped.
The jig 5 has a circular opening 7 in its base 9 and a pair of legs 11A and 11B whicn form a leg of the U. As shown in FIG. 3, the legs 11A and 11B are spaced apart and each leg has a notch, 13A and 13B respectively, formed therein. The legs and notcnes are sized to accommodate microdot holder 43, as described herein, and thereby comprise means for holding the microdot. Alternatively, the legs can be of an inverted L-shape so the notches essentially extend from the underside of base 9 to the snort arm portion of each L.
Jig 5 also includes a bifurcated plate 51, having legs 61A and 61B, as shown in FIG. 3. Plate
51 is hinged to jig 5 by a pivot pin 55, connected to a depending flange 57, as shown in FIG 4. Legs 61A and 61B receive holder 43, as shown in FIG. 3. A pair of slots 47 in holder 43, shown in FIG. 5, receive legs 61A and 61B by allowing legs 61A and 61B to slide into slots 47.
Because the teeth over which the jig fits vary in size, the jig includes an adjustment means 15 to accommodate the jig to the size of a respective tooth. Means 15 includes a movable jaw 17 located between the legs of the jig. The jaw has a curved inner face 19 to fit against the curved side of a tooth T. One end of a screw 21 is attached to the outer face of jaw 17 and the screw extends through leg 23 of the jig. A sleeve 25 projects outwardly from the outer wall of leg 23 and screw 21 extends through the sleeve and attaches to a knob 27 which is manually operable to adjust the position of the jaw. The screw 21' may be remotely driven by a flexible cable 28, shown in phantom in FIG. 3, if desired.
Apparatus 1 may also include a light trans¬ mission means 28, snown in FIG. 6, for transmitting ultraviolet (uv) light from a source of uv light to the microdot. Means 29 includes a wand 31 which is a long, cylindrical wand or light guide made of a uv light transmitting material. It will be understood that bright, white light may also be used witn some adhesives, as it is known in the art. In operation, a tooth T to which a microdot is. to be bonded is first prepared, for example, by treating its outer surface witn pumice or a similar material, as is described in detail in application Serial No. 936,597. A microdot M is then placed in the cavity 40 of stage 42, as shown in FIG. 6. Hol¬ der 43 is then placed over tne microdot M and the microdot is observed under magnification to check the microdot for correct indicia and tor flaws. Lens 41 of holder 43 may be a multipower lens, for example 2X. However, additional magnification, from an auxiliary lens, may be used to obtain sufficient magnification. The microdot M and holder 43 are aligned with the aligning mark 44 of holder 43 placed at the top of microdot M. Holder 43 is removed from stage 42 and a drop of transparent adhesive A is placed in holder 43. Holder 43 is again placed over microdot M with aligning mark 44 at the top of micro- dot M. Light wand 31 is then placed in holder 43, for example, as shown in FIG. 5, and uv or bright light is transmitted through lignt wand 31, through lens 41 and into the adhesive A. Adhesive A cures in contact with lens 41 and holder 43 and is at least temporarily bonded thereto. The contact between adhesive A, lens 41 and holder 43 excludes air from the surface of adhesive A. Adhesive A cures without an air inhibited layer at its surface and remains transparent.
After adhesive Ά is cured, holder 43 is removed from stage 42. Microdot M remains bonded in nolder 43. A drop of a second adhesive B is placed on the back side of microdot M and the holder 43 is placed in legs 61A and 61B o.f jig 5. Adhesive B may be an opaque adhesive, for example white, to provide a suitable background to read microdot M. The orien¬ tation mark 44 insures proper alignment of the micro- dot on tooth T. Jig 5 is positioned over tooth T, as shown in FIG. 4. Jaw 17 of jig 5 is adjusted so that jig 5 fits properly over tooth T. Then legs 61A and 61B are pivoted to place holder 43 in contact with tooth T, as shown in FIG. 4. When jig 5 and nolder 43 are in place light wand 31 is positioned on nolder 43 and light is introduced through lens 41 and adne- sive A to cure adhesive B. Lens 41 is glass and holder 43 is con¬ structed of a self-lubricating material, such as TEF¬ LON (TM, DuPont), as is stage 42. Consequently, the bond between the adhesives, microdot M and tooth T is much stronger than the bond between adhesive A, hol- der 43 and lens 41. Holder 43 and lens 41 are read¬ ily separated from the microdot and adhesive assembly by pulling outwardly on holder 43.
It will be appreciated that cavity 40 and holder 43 are sized to provide means to meter a suit- able quantity of adhesives A and B to microdot M.
For example, adhesive A is preferably about 0.3 mm in thickness and adhesive B is preferably about 0.5 mm in thic ness. Moreover, holder 43 and jig 5 accur¬ ately position microdot M on a tooth T in proper alignment and suitable orientation so that the micro- dot M can be easily read to obtain information from the indicia thereon.
It will be appreciated by those skilled in the art tnat various cnanges may be made in the in- vention disclosed herein without departing from the spirit of the invention. The invention is not to be limited to the specifics disclosed herein for pur¬ poses of illustration, but only by the scope of the claims appended hereto and the equivalents thereof.
