Abstract

Abstract A computing system is disclosed which operates using a digital computer which is programmed with a known programme, and information is fed into the computer from an input unit which incorporates a means to apply specific values for the initial conditions of selected variables and further means which are manually actuable to vary the value of the quantity representing a designated variable from its initial condition during computation in order that the response to such variation may be monitored on a display unit which conveniently is in the form of a video display unit. Additionally monitoring means in the form of lights which are operable in response to constraint violation may be included. The manually actuable means is disclosed in a form which is electronic.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 137 words
A computing system having a computing section for computing according to a predetermined programme, an input unit coupled to feed information into said computing section and a display unit coupled to said computing section to display information contained therein, and wherein said input unit includes means to apply to said computing section quantities representative of the initial conditions of variables of said information, manually-actuable means for varying the value of the quantity representing a designated variable from its initial condition, electronic circuitry for generating a train of pulses, said manually-actuable means comprising a manually rotatable element arranged to operate said electronic circuitry to generate a train of pulses to vary said value, and an up/down counter arranged to receive said train of pulses and the value of said designated variable and to output an altered value thereof.
Claim 2
Dependent Claim 137 words
A computing system having a computing section for computing according to a predetermined programme, an input unit coupled to feed information into said computing section and a display unit coupled to said computing section to display information contained therein, and wherein said input unit includes means to apply to said computing section quantities representative of the initial conditions of variables of said information, manually-actuable means for varying the value of the quantity representing a designated variable from its initial condition, electronic circuitry for generating a train of pulses, said manually-actuable means comprising a manually rotatable element arranged to operate said electronic circuitry to generate a train of pulses to vary said value, and an up/down counter arranged to receive said train of pulses and the value of said designated variable and to output an altered value thereof.
Claim 3
Dependent Claim 25 words
A computing system according to claim 1 wherein said input unit includes monitoring means responsive to the occurrence of predetermined conditions within said computing section.
Claim 4
Dependent Claim 16 words
A computing system according to claim 2, wherein said monitoring means includes a plurality of lights.
