Abstract

Abstract A data selection and decoding system useful for selective analysis and speedy assimilation of a large volume of data, in which the data, is set out as an array of code characters. A decoder mask is used to read data from the array, the mask having a viewing slot for viewing a chosen line and bearing, alongside the slot, decoding keys. The mask is made up of sheet portions, each with a viewing slot and possibly bearing decoding keys on each side. By folding the mask so as to reveal the sheet portion or the side of a sheet portion appropriate to a chosen row or column, characters, visible through the slot, can be quickly decoded.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 69 words
A decoder mask, for selecting and decoding data on a reference sheet in the form of an array of code characters arranged in a plurality of lines, the decoding mask having a viewing slot for selecting a chosen line on the reference sheet, and bearing decoding keys alongside the slot at a spacing and in a sequence corresponding to the spacing and sequence of characters in the chosen lines.
Claim 2
Dependent Claim 69 words
A decoder mask, for selecting and decoding data on a reference sheet in the form of an array of code characters arranged in a plurality of lines, the decoding mask having a viewing slot for selecting a chosen line on the reference sheet, and bearing decoding keys alongside the slot at a spacing and in a sequence corresponding to the spacing and sequence of characters in the chosen lines.
Claim 3
Dependent Claim 63 words
A mask according to claim 1 comprising a series of sheet portions each having a viewing slot and associated together in a stack such that the viewing slots are in alignment, the sheet portions being displaceable to reveal a sheet portion or one side of a sheet portion bearing decoding keys appropriate to any chosen line or column of characters in the array.
Claim 4
Dependent Claim 18 words
A mask according to claim 2 comprising a sheet of material which is folded several times concertina fashion.
Claim 5
Dependent Claim 24 words
A mask according to claim 2 or claim 3 wherein at least some of the sheet portions bear decoding keys on each side .thereof.
Claim 6
Dependent Claim 25 words
A decoding mask for selecting and coding data constructed and arranged substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.
Claim 7
Dependent Claim 25 words
A decoding mask for selecting and coding data constructed and arranged substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.
Claim 8
Dependent Claim 52 words
A data selection and decoding system comprising a reference sheet bearing an array of code characters arranged in a plurality of lines, the characters in each line being arranged at a predetermined spacing-and in a predetermined sequence, and a decoder mask according to any one of the preceding claims 1 to 5.
