Abstract
A tire or other rubber item is described that has a surface such as a sidewall. A region on the surface includes a plurality of protrusions. The protrusions are positioned in a pseudo-random pattern within the region. Various features of the protrusions may be varied in a random or pseudo-random manner.
Claims20
An apparatus, comprising:
- a tire having at least one surface;
- at least one region on the surface including a plurality of protrusions;
- and
- the protrusions being positioned in a pseudo-random pattern within the region.
The apparatus of claim Error! Bookmark not defined, wherein the pseudo-random pattern is defined by a predefined minimum distance between any two adjacent ones of the protrusions.
The apparatus of claim Error! Bookmark not defined, wherein the pseudo-random pattern is defined by a predefined maximum distance between any two adjacent ones of the protrusions.
The apparatus of claim Error! Bookmark not defined, wherein individual ones of the protrusions are less than 1 millimeter in height.
The apparatus of claim Error! Bookmark not defined, wherein a maximum width of individual ones of the protrusions is less than 1 millimeter.
The apparatus of claim Error! Bookmark not defined, wherein the protrusions comprise a cross-section in a shape of a circle.
The apparatus of claim Error! Bookmark not defined, wherein the protrusions comprise a cross-section in a shape of a polygon.
The apparatus of claim Error! Bookmark not defined, wherein the protrusions comprise an amorphous cross-section.
The apparatus of claim Error! Bookmark not defined, wherein a shape of a cross-section of individual ones of the protrusions differs relative to the shape of the cross-section of other ones of the protrusions.
The apparatus of claim Error! Bookmark not defined, wherein a size of the protrusions is specified such that the protrusions cannot be resolved by a naked human eye at a distance of at least 1 meter.
The apparatus of claim Error! Bookmark not defined, further comprising:
- each of the protrusions having a one of a plurality of surface contours;
- wherein each of the surface contours are disposed at a distal end of a respective one of the protrusions;
- and
- a first one of the surface contours is unique with respect to a plurality of other ones of the surface contours.
The apparatus of claim Error! Bookmark not defined, wherein a plurality of the protrusions have a common shape, and at least a first one of the protrusions is positioned with a first angular position and at least a second one of the protrusions is positioned with a second angular position, where the first angular position differs relative to the second angular position.
A method, comprising:
- creating a plurality of protrusions within at least one region on a surface of a tire;
- and
- wherein positions of the protrusions within the at least one region are arranged in a pseudo-random pattern.
The method of claim Error! Bookmark not defined, wherein individual ones of the protrusions are less than 1 millimeter in height and have a maximum width of less than 1 millimeter.
An apparatus, comprising:
- an item including rubber surface;
- at least one region on the rubber surface, the at least one region including a plurality of protrusions;
- and
- the protrusions being positioned in a pseudo-random pattern within the region.
