Abstract
Abstract A data entry keypad assembly, comprising a keypad including an array of keys, and a positioning locator secured to the keypad to form a unitary keypad assembly therewith, whereby the keypad assembly is selectively positionable at a desired locus of a data field to permit accurate inputting of data by the keypad to a digital computer operatively coupled therewith. Data processing systems comprising a digital computer operatively connected to such keypad assembly are disclosed, together with a source code computer program operatively associable with a digital computer of a type employing an MS-DOS, or compatible, operating system, and arranged to actuate audio signal generating means, to provide audio feedback indicative of a specific key of the keypad being actuated, and to assist in minimizing data entry inputting errors. The keypad assembly, computer software, and data processing system of the invention have particular utility to the inputting of primary DNA nucleotide sequence data from autoradiograms into a digital computer for storage and retrieval, and/or processing thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
238 words
A data processing system for analyzing data contained on or visible through a two dimensional surface, comprising: (a) a digital computer; and (b) a keypad assembly for inputting alpha-numeric data into said digital computer, said keypad assembly comprising: (i) a housing having a substantially flat bottom surface and sized such that it may be manually grasped and moved by hand over a flat two dimensional surface in any direction on which said housing is supported by said housing flat bottom surface; (ii) a viewing port formed in said housing comprising a transparent viewing window enabling data contained on or visible through said two dimensional surface when in sliding contact with said housing bottom surface to be seen through said transparent viewing window; and (iii) a keypad secured and positioned in said housing at a location proximate but offset from said transparent viewing window, including: (a) a plurality of manually actuatable keys for entering alpha-numeric data; (b) signal processing means within said housing adapted when a selected key is pressed to generate selected alpha-numeric data dependent upon which key is pressed, said selected alpha-numeric data corresponding to data contained on or visible through said two dimensional surface; and (c) signal transmitting means operatively connecting in signal in signal transmission relationship said keypad keys to said digital computer enabling each respective key when actuated to send to said digital computer the said selected alpha-numeric data corresponding to the key pressed.
Claim 2
Dependent Claim
238 words
A data processing system for analyzing data contained on or visible through a two dimensional surface, comprising: (a) a digital computer; and (b) a keypad assembly for inputting alpha-numeric data into said digital computer, said keypad assembly comprising: (i) a housing having a substantially flat bottom surface and sized such that it may be manually grasped and moved by hand over a flat two dimensional surface in any direction on which said housing is supported by said housing flat bottom surface; (ii) a viewing port formed in said housing comprising a transparent viewing window enabling data contained on or visible through said two dimensional surface when in sliding contact with said housing bottom surface to be seen through said transparent viewing window; and (iii) a keypad secured and positioned in said housing at a location proximate but offset from said transparent viewing window, including: (a) a plurality of manually actuatable keys for entering alpha-numeric data; (b) signal processing means within said housing adapted when a selected key is pressed to generate selected alpha-numeric data dependent upon which key is pressed, said selected alpha-numeric data corresponding to data contained on or visible through said two dimensional surface; and (c) signal transmitting means operatively connecting in signal in signal transmission relationship said keypad keys to said digital computer enabling each respective key when actuated to send to said digital computer the said selected alpha-numeric data corresponding to the key pressed.
Claim 3
Dependent Claim
50 words
A data processing system according to claim 1, wherein said housing includes a manually rotatable collar, said transparent viewing window is mounted in said rotatable collar, and said viewing window includes a visual reference marker thereon thereby enabling said visual reference marker to be selectively oriented relative to said housing.
Claim 4
Dependent Claim
25 words
A data processing system according to claim 2, wherein said visual reference marker comprises a set of orthogonal cross-hairs secured to said transparent viewing window.
Claim 5
Dependent Claim

Claim 7
Dependent Claim
43 words
A data processing system according to claim 1, wherein said keypad assembly includes a substantially planar sheet of material forming at least a portion of said housing flat bottom surface and said transparent viewing window is formed in said planar sheet of material.
Claim 8
Dependent Claim
42 words
A data processing system according to claim 1, wherein said digital computer includes an asynchronous port and said signal transmitting means include a coupling element operatively connecting in signal transmission relationship said keypad keys to said asynchronous port of said digital computer.
Claim 9
Dependent Claim
34 words
A data processing system according to claim 1 wherein said two dimensional surface contains data arranged in a number of columns and said keys are arranged by rows and a equal number of columns.
Claim 10
Dependent Claim
