Abstract
Abstract Representation of designs using pattern members such as domino pattern blocks. The design is subdivided into a plurality of subordinate areas which are assigned values in accordance with a prescribed characteristic such as brightness. The assigned values are coordinated with those of the pattern members which are then substituted into the subordinate areas to realize the desired patterned representation of the design.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
154 words
The method of representing a design by pattern members in the form of whole dominoes, each having two approximately square halves, which comprises the steps of: (1) subdividing the design into a plurality of subordinate areas; (2) assigning a value to each subordinate area in accordance with a prescribed characteristic; (3) coordinating the assigned values with values of the pattern members, including the evaluation of the pattern members in terms of groups of the sub-areas, which are evaluated in terms of a plurality of horizontal and vertical pairs, with a final pairing assignment made in accordance with the evaluation that enhances unbalance given by the numerical magnitudes of the difference of values of each pair of sub-areas and the pairing of sub-areas for producing maximal unblances are assigned to selective ones of the pattern members; and (4) substituting the coordinated pattern members for the sub-areas; thereby to form a patterned representation of said design.
Claim 2
Independent Claim
154 words
The method of representing a design by pattern members in the form of whole dominoes, each having two approximately square halves, which comprises the steps of: (1) subdividing the design into a plurality of subordinate areas; (2) assigning a value to each subordinate area in accordance with a prescribed characteristic; (3) coordinating the assigned values with values of the pattern members, including the evaluation of the pattern members in terms of groups of the sub-areas, which are evaluated in terms of a plurality of horizontal and vertical pairs, with a final pairing assignment made in accordance with the evaluation that enhances unbalance given by the numerical magnitudes of the difference of values of each pair of sub-areas and the pairing of sub-areas for producing maximal unblances are assigned to selective ones of the pattern members; and (4) substituting the coordinated pattern members for the sub-areas; thereby to form a patterned representation of said design.
Claim 3
Dependent Claim
11 words
The method of claim 1 wherein said prescribed characteristic is brightness.
Claim 4
Dependent Claim
23 words
The method of claim 2 wherein said design has a number of original brightness levels exceeding the maximum number of any pattern member.
Claim 5
Dependent Claim
18 words
The method of claim 1 wherein the design is created using a multiplicity of complete sets of dominoes.
Claim 6
Dependent Claim
23 words
The method of claim 1 wherein each pattern member has a face which is either blank or bears on or more spots thereon.
Claim 7
Dependent Claim
12 words
The method of claim 5 wherein the spots are of equal size.
Claim 8
Dependent Claim
14 words
The method of claim 6 wherein the spots are arranged in a regular pattern.
Claim 9
Dependent Claim
27 words
The method of claim 7 wherein the face is of a first background color and the spots are of a different color having a greater brightness level.
Claim 10
Dependent Claim
17 words
The method of claim 8 wherein the background color is black and the spot color is white.
Claim 11
Dependent Claim
12 words
The method of claim 5 wherein each member has two adjoining faces.
Claim 12
Dependent Claim
13 words
The method of claim 10 wherein the adjoining faces are the same size.
