Abstract

An apparatus for use in scanning a material includes a top member having a first body with a first plurality of holes; a bottom member having a second body with a second plurality of holes; and an interconnecting member connecting the top member and the second member to provide a gap between the top member and the bottom member. Each hole in the top member is aligned with a corresponding hole in the bottom member to form a hole-pair.

First claim

What is claimed is:

1. An apparatus for use in scanning a material, comprising:
a top member having a first body with a first plurality of holes;
a bottom member having a second body with a second plurality of holes; and
an interconnecting member connecting the top member and the second member forming a fixture assembly having a gap receptive of the material to be scanned between the top member and the bottom member, the interconnecting member establishing an alignment of the first plurality of holes and the second plurality of holes; and
a plurality of wheels coupled to the top member and the bottom member, the plurality of wheels spanning the gap.

2. The apparatus of claim 1 , wherein each of the first plurality of holes is configured to receive a corresponding shaped sensor.

3. The apparatus of claim 1 , wherein each of the second plurality of holes is configured to receive a corresponding shaped sensor.

4. The apparatus of claim 1 , wherein the interconnecting member is coupled to each of the top member and the bottom member along a longitudinal edge of the apparatus.

5. The apparatus of claim 1 , wherein the interconnecting member is coupled to each of the top member and the bottom member with a plurality of screws.

6. The apparatus of claim 1 , wherein the plurality of wheels are configured for rotational engagement with an edge of the material.

7. The apparatus of claim 1 , wherein the top member is made from a polyethylene or a metal.

8. The apparatus of claim 1 , wherein the bottom member is made from a polyethylene or a metal.

9. The apparatus of claim 1 , wherein the interconnecting member is made from a polyethylene or a metal.

10. A method of scanning a material, comprising:
providing a fixture assembly comprising:
a top member having a first body with a first plurality of holes;
a bottom member having a second body with a second plurality of holes; and
an interconnecting member connecting the top member and the second member to provide a gap between the top member and the bottom member;
wherein at least one of the first plurality of holes is aligned with at least one of the second plurality of holes to form a hole-pair;
inserting an edge of the material into the gap;
inserting a first sensor in the at least one of the first plurality of holes;
inserting a second sensor in the at least one of the second plurality of holes; and
measuring at least an amplitude of a sound wave passing from one of the first and second sensors to the other of the first and second sensors through the material.

11. The method of claim 10 , further comprising:
moving the fixture assembly along a spanwise length of the material to a new scanning location; and
measuring at least the amplitude of a sound wave through the material at the new scanning location.

12. The method of claim 10 , wherein the interconnecting member is connected to each of the top member and the bottom member along a longitudinal edge of the fixture assembly.

13. The method of claim 10 , wherein the interconnecting member is connected to each of the top member and the bottom member with a plurality of screws.

14. The method of claim 10 , wherein a plurality of wheels are coupled to each of the top member and the bottom member.

15. The method of claim 14 , wherein the plurality of wheels are in rotational engagement with an edge of the material.

16. The method of claim 10 , wherein the top member is made from a polyethylene or a metal.

17. The method of claim 10 , wherein the bottom member is made from a polyethylene or a metal.

18. The method of claim 10 , wherein the interconnecting member is made from a polyethylene or a metal.
