What is claimed is:
1. A laser range finder comprising:
a laser transmitting section for producing a series of transmitted laser pulses directable towards a target and producing a plurality of returned laser pulses at least partially reflected therefrom in response thereto;
a laser receiving section for receiving at least a portion of said plurality of returned laser pulses;
a central processing section coupled to said laser transmitting and laser receiving sections for determining a distance to said target based upon a time of flight of said transmitted and returned laser pulses;
a user viewable display coupled to said central processing section for displaying said determined distance to said target; and
a user actuatable mode switch coupled to said central processing section for indicating a specified distance less than which returned pulses from an object intervening between said laser range finder and said target will be ignored in said distance determination.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A mat comprising:
a rubber layer comprising rubber particles and a matrix material proximate the rubber particles, wherein the matrix material comprises a barrier material and a binder material; and
a textile layer thermally bonded to the rubber layer;
wherein the textile layer comprises a backing layer comprising polyester; and
wherein the textile layer further comprises a tufted textile surface coupled to the backing layer.
2. The mat of claim 1, wherein the rubber particles comprise recycled rubber and the barrier material comprises titanium dioxide.
3. The mat of claim 1, wherein the binder material comprises an isocyanate binder.
4. The mat of claim 1, wherein the binder material is adapted to bond with a polyester material at elevated temperatures.
5. The mat of claim 1, wherein the backing layer is thermally bonded to the rubber layer.
6. The mat of claim 1, wherein the textile surface comprises an olefin material.
7. The mat of claim 6, wherein the olefin material comprises at least one of nylon, cotton, polyester, polypropylene, and polyethylene.
8. The mat of claim 6, wherein the textile surface is a blended material.
9. The mat of claim 6, wherein the textile surface also comprises monofilament fibers.
10. The mat of claim 1, wherein the rubber layer comprises a first surface and a second surface, wherein the textile layer covers at least a portion of the first surface.
11. The mat of claim 10, wherein the textile layer covers the entire first surface.
12. The mat of claim 10, wherein the textile layer covers at least a portion of both the first and second surfaces.
13. The mat of claim 1, wherein the barrier material acts to reduce or prevent migration of breakdown products from the rubber particles.
14. The mat of claim 1, wherein the binder material comprises between approximately 6 and 10 percent of the rubber layer.
15. The mat of claim 1, wherein the rubber layer further comprises a coloring pigment.
