Abstract

An animal tag and methods for making an animal tag include a primary body of material (e.g., that includes a circuit holding portion and an animal attachment portion), a circuit assembly, and a cover configured to cover the circuit assembly. The cover is welded to the primary body of material using light radiation.

Claims

1. An animal tag comprising:

a primary body of material comprising at least a circuit holding portion and an animal attachment portion, wherein the animal attachment portion is configured to be attached to an animal, wherein at least one recess is defined in the circuit holding portion, and further wherein the material of the primary body defining the at least one recess comprises plastic material that absorbs light radiation of at least a first weld wavelength;

a circuit assembly comprising at least an antenna to be received within the recess defined in the circuit holding portion of the primary body of material; and

a cover configured to cover the circuit assembly received in the at least one recess defined in the circuit holding portion of the primary body of material, wherein the cover comprises a plastic material that is transmissive to light radiation of at least the first weld wavelength such that light radiation of at least the first weld wavelength can pass through the flat cover and be absorbed by the plastic material defining the at least one recess so as to join the cover and the plastic material defining the at least one recess to form a sealed cavity in which the circuit assembly is located.

2. The animal tag of claim 1, wherein the plastic material of the cover that is transmissive to light radiation of at least the first weld wavelength is opaque.

3. The animal tag of claim 1, wherein the first weld wavelength is 980 nanometers.

4. The animal tag of claim 1, wherein the at least one recess comprises a first recess in the circuit holding portion configured to receive the circuit assembly and comprises a second recess in the circuit holding portion corresponding to the shape of the cover, and further wherein a sealing interface between edge portions of the cover and the plastic material defining the at least one recess is used to provide the sealed cavity in which the circuit assembly is located.

5. The animal tag of claim 1, wherein the primary body of material comprises a first side surface and a second side surface, wherein the at least one recess is defined in the first side surface to a predetermined depth, wherein the cover is planar with the first side surface when the cover is joined with the plastic material defining the recess to form the sealed cavity in which the circuit assembly is positioned.

6. The animal tag of claim 1, wherein the circuit assembly comprises a flat circuit assembly, and cover comprises a flat cover, wherein the flat circuit assembly and the flat cover are configured to be received within the at least one recess.

7. An animal tag comprising:

a primary body of material comprising at least a circuit holding portion and an animal attachment portion, wherein the animal attachment portion is configured to be attached to an animal, wherein at least the circuit holding portion comprises plastic material that absorbs light radiation of at least a first weld wavelength;

a circuit assembly comprising at least an antenna positioned adjacent the circuit holding portion; and

a cover configured to cover the circuit assembly, wherein the cover comprises a plastic material that is transmissive to light radiation of at least the first weld wavelength such that light radiation of at least the first weld wavelength can pass through the cover and be absorbed by the plastic material of the circuit holding portion so as to join the cover and the plastic material of the circuit holding portion to form a sealed cavity in which the circuit assembly is located.

8. The animal tag of claim 7, wherein the cover is opaque.

9. The animal tag of claim 7, wherein the first weld wavelength is 980 nanometers.

10. The animal tag of claim 7, wherein the circuit assembly comprises a flat circuit assembly, and further wherein the cover comprises a flat cover, wherein the flat circuit assembly and the flat cover are configured to be received within the at least one recess.

11. A method for making an animal tag, the method comprising:

providing a primary body of material comprising at least a circuit holding portion and an animal attachment portion, wherein the animal attachment portion is configured to be attached to an animal, wherein at least one recess is defined in the circuit holding portion, and further wherein the material of the primary body defining the at least one recess comprises plastic material that absorbs light radiation of at least a first weld wavelength;

positioning a circuit assembly comprising at least an antenna within the at least one recess defined in the circuit holding portion of the primary body of material;

providing a cover configured to cover the circuit assembly received in the at least one recess defined in the circuit holding portion of the primary body of material, wherein the cover comprises a plastic material that is transmissive to light radiation of at least the first weld wavelength; and

passing light radiation of at least the first weld wavelength through the cover to be absorbed by the material defining the at least one recess so as to join the cover and the plastic material defining the at least one recess to form a sealed cavity in which the circuit assembly is located.

12. The method of claim 11, wherein the cover is opaque.

13. The method of claim 11, wherein the first weld wavelength is 980 nanometers.

14. The method of claim 11, wherein the at least one recess comprises a first recess in the circuit holding portion configured to receive the circuit assembly and comprises a second recess in the circuit holding portion corresponding to the shape of the cover, and further wherein a sealing interface between edge portions of the cover and the material defining the at least one recess is used to provide the sealed cavity in which the circuit assembly is located.

15. The method of claim 11, wherein the primary body of material comprises a first side surface and a second side surface, wherein the at least one recess is defined in the first side surface to a predetermined depth, wherein the cover is planar with the first side surface when the cover is joined with the plastic material defining the recess to form the sealed cavity in which the circuit assembly is positioned.

16. The method of claim 11, wherein the circuit assembly comprises a flat circuit assembly, and further wherein the cover comprises a flat cover, wherein the flat circuit assembly and the flat cover are configured to be received within the at least one recess.

17. A method for making an animal tag, the method comprising:

providing a primary body of material comprising at least a circuit holding portion and an animal attachment portion, wherein the animal attachment portion is configured to be attached to an animal, wherein at least the circuit holding portion comprises plastic material that absorbs light radiation of at least a first weld wavelength;

locating a circuit assembly comprising at least an antenna adjacent the circuit holding portion;

positioning a cover over the circuit assembly, wherein the cover comprises a plastic material that is transmissive to light radiation of at least the first weld wavelength; and

passing light radiation of at least the first weld wavelength through at least portions of the cover to be absorbed by the plastic material of the circuit holding portion so as to join the cover and the circuit holding portion to form a sealed cavity in which the circuit assembly is located.

18. The method of claim 17, wherein the cover is opaque.

19. The method of claim 17, wherein the first weld wavelength is 980 nanometers.

20. The method of claim 17, wherein the circuit assembly comprises a flat circuit assembly, and further wherein the cover comprises a flat cover, wherein the flat circuit assembly and the flat cover are configured to be received within the at least one recess.
