Patent ID: 8438200

Claim:
A handheld device used for constructing arches comprising: a power source; a memory component including instructions for generating a plurality of arc defining coordinate pairs; a processor configured to access said instructions and generate a graphical representation of said arc defining pairs; a display configured to visually display said graphical representation of said arc defining pairs; and a plurality of keys or button for entering alphanumeric characters to said processor; wherein said instructions for generating arc defining coordinate pairs are configured to prompt a user for a desired arc width and a height corresponding to a desired arch and use said desired arc width and height to generate said graphical representation of said arc defining pairs corresponding to said desired arch; wherein said instructions further comprise; instructions which, when accessed by said processor, generate a user interface prompting a user to enter a desired width dimension of a desired arch; instructions which, when accessed by said processor, incorporate said desired width dimension and said desired height dimension to generate coordinate pairs corresponding to a coordinate system, wherein said coordinate pairs correspond to points defining an arc, said arc corresponding to said width and height dimensions of said desired arch; and wherein said coordinate pairs are given according to a standard Cartesian Coordinate System.
