Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
108 words
A detector for sensing change in data comprising, in combination, primary storage means for storing current data, secondary storage means connected to the primary storage means for storing target data, current data becoming target data when transferred from primary to secondary storage, means for determining coincidence between current and target data within a tolerance band, means for counting to a predetermined number consecutive times coincidence is determined, and means responsive to a determination of no coincidence or to reaching said predetermined number for transferring data from primary to secondary storage, whereby the determination of no coincidence signifies data change and reaching the predetermined number signifies no data change.
Claim 2
Dependent Claim
108 words
A detector for sensing change in data comprising, in combination, primary storage means for storing current data, secondary storage means connected to the primary storage means for storing target data, current data becoming target data when transferred from primary to secondary storage, means for determining coincidence between current and target data within a tolerance band, means for counting to a predetermined number consecutive times coincidence is determined, and means responsive to a determination of no coincidence or to reaching said predetermined number for transferring data from primary to secondary storage, whereby the determination of no coincidence signifies data change and reaching the predetermined number signifies no data change.
Claim 3
Dependent Claim
19 words
A detector according to claim 1 wherein switch means are provided for adjusting the width of the tolerance band.
Claim 4
Dependent Claim
19 words
A detector according to claim 1 wherein switch means are provided for adjusting the size of the predetermined number.
Claim 5
Dependent Claim
31 words
A detector according to claim 1 wherein means are provided responsive to the determination of coincidence following the reaching of said predetermined number for transferring data from primary to secondary storage.
Claim 6
Dependent Claim
49 words
A detector for sensing change in data comprising, in combination, means for determining whether or not change in data is within a tolerance band, and means for counting to a predetermined number consecutive times data is within the tolerance band, whereby reaching the predetermined number signifies no data change.
Claim 7
Dependent Claim
49 words
A detector for sensing change in data comprising, in combination, means for determining whether or not change in data is within a tolerance band, and means for counting to a predetermined number consecutive times data is within the tolerance band, whereby reaching the predetermined number signifies no data change.
Claim 8
Dependent Claim
86 words
A detector for sensing change in data comprising, in combination, primary storage means for storing current data, secondary storage means connected to the primary storage means for storing target data, current data becoming target data when transferred from primary to secondary storage, means for determining coincidence between current and target data, means for counting to a predetermined number consecutive times coincidence is determined, and means responsive to a determination of no coincidence or to reaching said predetermined number for transferring data from primary to secondary storage.
Claim 9
Dependent Claim
86 words
A detector for sensing change in data comprising, in combination, primary storage means for storing current data, secondary storage means connected to the primary storage means for storing target data, current data becoming target data when transferred from primary to secondary storage, means for determining coincidence between current and target data, means for counting to a predetermined number consecutive times coincidence is determined, and means responsive to a determination of no coincidence or to reaching said predetermined number for transferring data from primary to secondary storage.
Claim 10
Dependent Claim
31 words
A detector according to claim 6 wherein means are provided responsive to the determination of coincidence following the reaching of said predetermined number for transferring data from primary to secondary storage.
Claim 11
Dependent Claim
129 words
A detector for sensing change in digital readout data comprising, in combination, means for applying check data change signals to the detector to initiate data sampling, primary storage means for storing current data, secondary storage means connected to the primary storage means for storing target data, current data becoming target data when transferred from primary to secondary storage, means responsive to said check signals for determining coincidence between current and target data within a tolerance band, means for counting to a predetermined number consecutive times coincidence is determined, and means responsive to a determination of no coincidence or to reaching said predetermined number for transferring data from primary to secondary storage, whereby the determination of no coincidence signifies data change and reaching the predetermined number signifies no data change.
Claim 12
Dependent Claim
129 words
A detector for sensing change in digital readout data comprising, in combination, means for applying check data change signals to the detector to initiate data sampling, primary storage means for storing current data, secondary storage means connected to the primary storage means for storing target data, current data becoming target data when transferred from primary to secondary storage, means responsive to said check signals for determining coincidence between current and target data within a tolerance band, means for counting to a predetermined number consecutive times coincidence is determined, and means responsive to a determination of no coincidence or to reaching said predetermined number for transferring data from primary to secondary storage, whereby the determination of no coincidence signifies data change and reaching the predetermined number signifies no data change.
Claim 13
Dependent Claim
59 words
A detector for sensing change in digital readout data comprising, in combination, means for applying check data change signals to the detector to initiate data sampling, means responsive to said check signals for determining whether or not change in data has occurred between samplings, and means for counting to a predetermined number consecutive times no data change has occurred.
Claim 14
Dependent Claim
59 words
A detector for sensing change in digital readout data comprising, in combination, means for applying check data change signals to the detector to initiate data sampling, means responsive to said check signals for determining whether or not change in data has occurred between samplings, and means for counting to a predetermined number consecutive times no data change has occurred.
Claim 15
Dependent Claim
31 words
