Abstract
Abstract An electronic counting system having a directional discriminator for accepting input signals representative of the count, a reversible up-down counter responsive to the directional discriminator for performing the counting function, a numerical display for displaying the value of the present count, and logic apparatus for the calculation and display of values for manual input to the up-down counter. The entry logic apparatus includes a keyboard for the manual entry of numerical data and function commands, a computer-calculator element for processing the numerical entry display for displaying the numerical data entered into the keyboard and the function results. A transfer switch applies the numerical data of the entry display to the up-down counter for setting the counter to the entry display value.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
In combination with an incremental measuring system system having a directional discriminator for accepting input count pulses, an up-down counter, and a counter output display, the improvement comprising: keyboard means for the manual entry of numerical data; calculator logic means responsive to said keyboard entry means for accepting the numerical data; digital display means responsive to said calculator logic means for displaying the manually entered numerical data; and means for transferring the value displayed by the display means to the up-down counter to set the output value of the up-down counter to correspond to the displayed value.
Claim 2
Dependent Claim
97 words
In combination with an incremental measuring system system having a directional discriminator for accepting input count pulses, an up-down counter, and a counter output display, the improvement comprising: keyboard means for the manual entry of numerical data; calculator logic means responsive to said keyboard entry means for accepting the numerical data; digital display means responsive to said calculator logic means for displaying the manually entered numerical data; and means for transferring the value displayed by the display means to the up-down counter to set the output value of the up-down counter to correspond to the displayed value.
Claim 3
Dependent Claim
18 words
The counting system of claim 1 wherein said calculator logic means comprises a multiple function calculator logic element.
Claim 4
Dependent Claim
103 words
An input system for manually setting the output value of an up-down counter of an incremental measuring system, comprising: keyboard means for the manual entry of numerical data and function commands; logic means responsive to said keyboard entry means for performing functions upon the numerical data in accordance with the function commands; means for displaying the manually entered numerical data and for displaying the numerical results from functions performed by said logic means; and means for transferring the value displayed by the display means to the up-down counter to set the output value of the up-down counter to correspond to the displayed value.
Claim 5
Dependent Claim
103 words
An input system for manually setting the output value of an up-down counter of an incremental measuring system, comprising: keyboard means for the manual entry of numerical data and function commands; logic means responsive to said keyboard entry means for performing functions upon the numerical data in accordance with the function commands; means for displaying the manually entered numerical data and for displaying the numerical results from functions performed by said logic means; and means for transferring the value displayed by the display means to the up-down counter to set the output value of the up-down counter to correspond to the displayed value.
Claim 6
Dependent Claim
14 words
The counting system of claim 3 wherein said displaying means comprises a digital display.
Claim 7
Dependent Claim
17 words
The counting system of claim 3 wherein said logic means comprises a multiple function calculator logic element.
Claim 8
Dependent Claim
108 words
An electronic counting system for use in an incremental measuring system, comprising: a directional discriminator for accepting input pulses representative of a quantity to be measured; an up-down counter responsive to said directional discriminator for generating the count value; numerical display means responsive to said up-down counter for numerically displaying the count value generated by said up-down counter; means including a keyboard for the manual entry of numerical data to be used for setting said up-down counter; and means for selectively transferring numerical values from said entry means to the up-down counter to set the count value of said up-down counter to correspond to the transferred numerical value.
Claim 9
Dependent Claim
108 words
An electronic counting system for use in an incremental measuring system, comprising: a directional discriminator for accepting input pulses representative of a quantity to be measured; an up-down counter responsive to said directional discriminator for generating the count value; numerical display means responsive to said up-down counter for numerically displaying the count value generated by said up-down counter; means including a keyboard for the manual entry of numerical data to be used for setting said up-down counter; and means for selectively transferring numerical values from said entry means to the up-down counter to set the count value of said up-down counter to correspond to the transferred numerical value.
Claim 10
Dependent Claim
46 words
The counting system of claim 6 wherein said entry means comprises: computer logic means responsive to said keyboard and to the manually entered numerical data; and means for numerically displaying the manually entered numerical data and for displaying numerical values calculated by said computer logic means.
