Abstract
Abstract A numerical positioning system having a desired position register and an overshoot register in which indications of increments of movement of the element being positioned, beyond the desired position, are stored as a position count in the overshoot register and the magnitude of the count of the overshoot register is transferred to the position register and algebraically combined with a succeeding indication of desired position to indicate the succeeding extent of movement required to reach the succeeding desired position. Flexibility is obtained by utilizing desired position and overshoot registers which are bidirectional and reversible and which when counted down to zero and beyond will change sign and start counting up.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
124 words
In apparatus for electrically controlling the positioning of a moveable element: position register means for storing a count indicative of a present desired position of the moveable element; means including a movement sensing transducer system for producing pulses for incrementally changing the count of said position register means in response to movement of said moveable element; drive means responsive to said position register means for controlling the movement of said moveable element; overshoot register means for storing a count indicative of movement of said moveable element to a position beyond a preceding desired position; and means for algebraically summing the count of said overshoot register means and said position register means before movement of said moveable element to said present desired position is completed.
Claim 2
Dependent Claim
124 words
In apparatus for electrically controlling the positioning of a moveable element: position register means for storing a count indicative of a present desired position of the moveable element; means including a movement sensing transducer system for producing pulses for incrementally changing the count of said position register means in response to movement of said moveable element; drive means responsive to said position register means for controlling the movement of said moveable element; overshoot register means for storing a count indicative of movement of said moveable element to a position beyond a preceding desired position; and means for algebraically summing the count of said overshoot register means and said position register means before movement of said moveable element to said present desired position is completed.
Claim 3
Dependent Claim
49 words
The apparatus as defined in claim 1 and further comprising: means including said drive means for causing the element to move in a positive or negative direction relative to an arbitrary zero position; and means for indicating the sign of the desired direction of movement of the moving element.
Claim 4
Dependent Claim
69 words
The apparatus as defined in claim 1 wherein said first named means comprises: direction pulse generating means having two output circuits, said direction pulse generating means generating a first pulse at one output circuit for each increment of movement of said moveable element in a first direction and a second pulse at the remaining output circuit for each increment of movement of said moveable element in a second direction.
Claim 5
Dependent Claim
59 words
The apparatus as defined in claim 3 and further comprising: directional sign means for indicating the sign of the desired direction of movement of the moving element; and circuit means coupling said directional sign means to said position register means together with either of said first or second pulses to control the direction of counting of said position register.
Claim 6
Dependent Claim
103 words
The apparatus as defined in claim 1 and further comprising: means for causing said element to move in a positive or negative direction relative to a selected zero position; direction sign means for indicating the sign of the desired movement of the moving element; and direction pulse generating means having two output circuits, said direction pulse generating means generating a positive direction pulse at one output circuit for each increment of movement of said moveable element in a positive direction and a negative direction pulse at the remaining output terminal for each increment of movement of said moveable element in a negative direction.
Claim 7
Dependent Claim
56 words
The apparatus as defined in claim 1 and further comprising: clock pulse generating means; and means coupling said clock pulse generating means to said overshoot register means and to said position register means for decreasing the count of said overshoot register means toward its minimum value and correspondingly increasing the count of said position register means.
Claim 8
Dependent Claim
69 words
The apparatus as defined in claim 1 and further comprising: clock pulse generating means capable of decreasing the count of said overshoot register means toward its minimum value and correspondingly increasing the count of said position register means; and gating means coupled to said clock pulse generating means, said gating means being capable of enabling said clock pulse generating means in the absence of movement of said moveable element.
Claim 9
Dependent Claim
129 words
The apparatus as defined in claim 1 and further comprising: means for causing the moveable element to move in a positive direction or a negative direction relative to a zero position; sign indicating means for indicating the sign of said overshoot register; sign indicating means for indicating the sign of the desired direction of movement of said moveable element; and clock pulse generating means coupled to said overshoot register means and to said position register means for decreasing the count of said overshoot register means towards its minimum value and increasing the count of said position register means correspondingly when the 1 signs of said sign indicating means are different and decreasing the count of said position register means when the signs of said indicating means are the same.
Claim 10
Dependent Claim
41 words
