Abstract
Abstract A stored-logic real time monitoring and control system which includes a first storage device for sequentially storing the switching logic descriptions of a desired combinational sequential or the like logic function to be performed and a second storage device for storing the present input status to the switching logic descriptions. Individual hardware versions of the desired switching logic descriptions are provided and selectively allowed to repetitively operate upon the monitored input signals in accordance with the stored switching logic descriptions in such a fashion as to allow the desired real time monitoring and control.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A stored-logic real time monitoring and control system comprising: means for storing switching logic descriptions of desired control and monitoring functions; means for providing a plurality of different hardware logic elements, each of which is representative of a different one of said switching logic descriptions; means for sequentially subjecting each logic element representative of said switching logic descriptions to an appropriate input stimulus; means for storing a last look condition resulting from said subjecting of each logic element to an appropriate input stimulus; and means for continuously allowing resulting control signals generated by said logic elements to direct the behavior of a system under control.
Claim 2
Dependent Claim
105 words
A stored-logic real time monitoring and control system comprising: means for storing switching logic descriptions of desired control and monitoring functions; means for providing a plurality of different hardware logic elements, each of which is representative of a different one of said switching logic descriptions; means for sequentially subjecting each logic element representative of said switching logic descriptions to an appropriate input stimulus; means for storing a last look condition resulting from said subjecting of each logic element to an appropriate input stimulus; and means for continuously allowing resulting control signals generated by said logic elements to direct the behavior of a system under control.
Claim 3
Dependent Claim
55 words
A stored-logic real time monitoring and control system as in claim 1 wherein said means for storing said switching logic descriptions is a sequentially readout memory device. 3. A stored-logic real time monitoring and control system as in claim 2 wherein said means for storing the last look conditions is a random access memory device.
Claim 4
Dependent Claim
91 words
A stored-logic real time monitoring and control system as in claim 3 wherein said means for subjecting each logic element to its appropriate input stimulus includes a function element selector for decoding a particular one of said switching logic description which is sequentially read from said sequentially readout memory device such that said input stimulus is applied to the hardware version logic element representative of said switching logic description and the output therefrom is either or both stored in said random access memory or gated for generating a proper control signal.
Claim 5
Dependent Claim
47 words
A stored-logic real time monitoring and control system as in claim 4 wherein is further included a first address register, a second address register, and a third address register for respectively selecting and directing a storage, monitor or output control function during the operation of said system.
Claim 6
Dependent Claim
22 words
A stored-logic real time monitoring and control system as in claim 5 wherein said sequentially readout memory device is a magnetic drum.
Claim 7
Dependent Claim
23 words
A stored-logic real time monitoring and control sYstem as in claim 6 wherein said random access memory device is a magnetic core matrix.
Claim 8
Dependent Claim
47 words
A stored-logic real time monitoring and control system as in claim 7 wherein is included input gating circuitry including at least an AND gate and an OR gate for receiving monitored information from a system under control and for applying the same to said magnetic core matrix.
Claim 9
Dependent Claim
48 words
A stored-logic real time monitoring and control system as in claim 8 wherein said means for continuously allowing resulting control signals includes output gating circuiting having at least an AND gate and a flip-flop gate for applying said resulting control signals to a system under monitor and control.
