Abstract
Abstract A system in which timing information is remotely set into a projectile to be fired. The system is configured to connect a time setting device, which contains (1) a plurality of setting switches, and (2) a plurality of read-out devices to an integrated circuit in the projectile by a minimum number of wires. The system functions to allow (1) hand setting of the timing information and (2) an error check, both at a remote location. The error check is provided as a visual read-out of data sent back from the integrated circuit after the timing information has been set.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
In combination: a first counting circuit for generating an actuation signal when said first counting circuit has reached a first predetermined count; means for setting a second count in said first counting circuit which includes; a second counting circuit for generating a counting signal while said second counting circuit is advancing; means for initially setting a third count in said second counting circuit; means for advancing said second counting circuit from said third count to a fourth predetermined count; means for applying said counting signal to said first counting circuit; a pulse generating circuit for causing said first counting circuit to count; and means responsive to a predetermined event for rendering said pulse generating circuit effective to cause said first counting circuit to count thereby enabling said first counting circuit to reach said first predetermined count and generate said actuation signal.
Claim 2
Dependent Claim
141 words
In combination: a first counting circuit for generating an actuation signal when said first counting circuit has reached a first predetermined count; means for setting a second count in said first counting circuit which includes; a second counting circuit for generating a counting signal while said second counting circuit is advancing; means for initially setting a third count in said second counting circuit; means for advancing said second counting circuit from said third count to a fourth predetermined count; means for applying said counting signal to said first counting circuit; a pulse generating circuit for causing said first counting circuit to count; and means responsive to a predetermined event for rendering said pulse generating circuit effective to cause said first counting circuit to count thereby enabling said first counting circuit to reach said first predetermined count and generate said actuation signal.
Claim 3
Dependent Claim
40 words
The combination as defined in claim 1 also including: means responsive to said second counting circuit reaching said fourth predetermined count for displaying information indicating that the count in said first counting circuit has in fact reached said second count.
Claim 4
Dependent Claim
29 words
The combination as defined in claim 1 in which said counting signal renders said first counting circuit responsive to said pulse generating circuit to count to said second count.
Claim 5
Dependent Claim
54 words
The combination as defined in claim 3 in which said predetermined event renders said first counting circuit effective to count at a first rate and said counting signal renders said first counting circuit responsive to said pulse generating circuit to count at a second rate, said second rate being greater than said first rate.
Claim 6
Dependent Claim
40 words
The combination as defined in claim 3 also including: means responsive to said second counting circuit reaching said fourth predetermined count for displaying information indicating that the count in said first counting circuit has in fact reached said second count.
Claim 7
Dependent Claim
83 words
The combination as defined in claim 5 in which said displaying means includes: a third counting circuit; a fourth counting circuit; means responsive to said second counting circuit reaching said fourth predetermined count for setting said third counting circuit to said count in said first counting circuit; means responsive to said setting of said third counting circuit for advancing said third counting circuit to a fifth predetermined count; and means for advancing said fourth counting circuit while said third counting circuit is advanced.
Claim 8
Dependent Claim
54 words
The combination as defined in claim 6 in which said predetermined event renders said first counting circuit effective to count at a first rate and said counting signal renders said first counting circuit responsive to said pulse generating circuit to count at a second rate, said second rate being greater than said first rate.
Claim 9
Dependent Claim
19 words
The combination as defined in claim 6 in which said displaying means is driven by said fourth counting circuit.
Claim 10
Dependent Claim
38 words
The combination as defined in claim 8 in which said predetermined event renders said first counting circuit responsive to said pulse generating circuit to count at a second rate, said second rate being greater than said first rate.
