Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
77 words
In a data processing system having means for generating program signals and data signals, a data verification device comprising: a. a register for receiving said data signals, b. an accumulator, c. means connecting said register and said accumulator, d. a comparator, e. means connecting said register and said comparator, and f. means responsive to said program signals for transferring said data signals from said register to said accumulator or for transferring said data signals to said comparator.
Claim 2
Dependent Claim
77 words
In a data processing system having means for generating program signals and data signals, a data verification device comprising: a. a register for receiving said data signals, b. an accumulator, c. means connecting said register and said accumulator, d. a comparator, e. means connecting said register and said comparator, and f. means responsive to said program signals for transferring said data signals from said register to said accumulator or for transferring said data signals to said comparator.
Claim 3
Dependent Claim
20 words
A system as set forth in claim 1 wherein said means responsive to said program signals is a program decoder.
Claim 4
Dependent Claim
3 words
an accumulator, and
Claim 5
Dependent Claim
3 words
an accumulator, and
Claim 6
Dependent Claim
16 words
means responsive to said program information for transmitting said data from said register to said accumulator.
Claim 7
Dependent Claim
16 words
means responsive to said program information for transmitting said data from said register to said accumulator.
Claim 8
Dependent Claim
37 words
A system as set forth in claim 2 further comprising a weight counter and means responsive to said weight counter for causing the contents of said register to be transferred to said accumulator a plurality of times.
Claim 9
Dependent Claim
20 words
A system as set forth in claim 3 where the number of said transfers is established by said program decoder.
Claim 10
Dependent Claim
37 words
A system as set forth in claim 4 wherein an input to said weight counter is connected to an output of said accumulator and wherein the contents of said accumulator change the contents of said weight counter.
Claim 11
Dependent Claim
21 words
A system as set forth in claim 1 wherein said program signals establish the existence of a check-digit in said accumulator.
Claim 12
Dependent Claim
22 words
A system as set forth in claim 1 wherein said means for generating program signals and data signals generates said signals alternately.
Claim 13
Dependent Claim
25 words
A system as set forth in claim 2 further comprising an input/output bus, said program signals and said data signals being carried on said bus.
Claim 14
Dependent Claim
20 words
A system as set forth in claim 8 wherein a check digit may be generated by said data verification device.
Claim 15
Dependent Claim
65 words
In a data entry system comprising a central control unit, said central control unit providing program information, a peripheral input device and a bus connecting said input device and said central control unit: a. generating means connected to said bus, b. said generating means responsive to said program information on said bus to perform arithmetic operations on data on said bus, said generating means comprising:
Claim 16
Dependent Claim
65 words
In a data entry system comprising a central control unit, said central control unit providing program information, a peripheral input device and a bus connecting said input device and said central control unit: a. generating means connected to said bus, b. said generating means responsive to said program information on said bus to perform arithmetic operations on data on said bus, said generating means comprising:
Claim 17
Dependent Claim
20 words
A system as set forth in claim 10 wherein said means responsive to said program information is a program decoder.
Claim 18
Dependent Claim
17 words
A system as set forth in claim 11 wherein said data originates in said central control unit.
Claim 19
Dependent Claim
20 words
A system as set forth in claim 12 wherein said program information and said data are interleaved on said bus.
Claim 20
Dependent Claim
16 words
A system as set forth in claim 13 wherein said peripheral input unit is a keyboard.
