Abstract
Abstract An arrangement for averaging the count received from a bidirectional pulse source such as a measuring machine position transducer is disclosed in which a relatively small capacity auxiliary counter is utilized in conjunction with a main counter, and includes means for causing the incoming pulses in either direction to bypass the auxiliary counter and pass to the main counter whenever the auxiliary counter is full in the direction of the incoming pulse. The count in the auxiliary counter is periodically sampled with the samples taken at regular intervals and an update signal reflecting the direction of the average count being added to the main counter and subtracted from the auxiliary counter at regular intervals.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
A counter averaging arrangement for averaging the net count of signals received from a bidirectional signal source comprising: bidirectional main counter means for counting said bidirectional signals; bidirectional auxiliary counting means for counting said bidirectional signals; directing means for causing only said auxiliary counter means to receive and count said bidirectional signals until the capacity of said auxiliary counter means to count further signals in one or the other direction is reached, and causing additional source signals in said one or the other direction to be counted by said main counting means as long as said auxiliary counting means cannot count signals in said one or the other direction; averager means for averaging the count contained in said auxiliary counter means over an interval of time; signal generating means changing the count in said main counter means in the direction of said average count and changing the count in said auxiliary counter means in the opposite direction of said average count.
Claim 2
Dependent Claim
161 words
A counter averaging arrangement for averaging the net count of signals received from a bidirectional signal source comprising: bidirectional main counter means for counting said bidirectional signals; bidirectional auxiliary counting means for counting said bidirectional signals; directing means for causing only said auxiliary counter means to receive and count said bidirectional signals until the capacity of said auxiliary counter means to count further signals in one or the other direction is reached, and causing additional source signals in said one or the other direction to be counted by said main counting means as long as said auxiliary counting means cannot count signals in said one or the other direction; averager means for averaging the count contained in said auxiliary counter means over an interval of time; signal generating means changing the count in said main counter means in the direction of said average count and changing the count in said auxiliary counter means in the opposite direction of said average count.
Claim 3
Dependent Claim
28 words
The arrangement of claim 1 wherein said signal generating means changes the count in said main and auxiliary counter means by said average count after each averaging interval.
Claim 4
Dependent Claim
20 words
The arrangement of claim 1 wherein said auxiliary counter means has a substantially smaller capacity than said main counter means.
Claim 5
Dependent Claim
41 words
The arrangement of claim 1 wherein said averager means includes means for obtaining a plurality of successive samples of said count of said auxiliary counter means over said interval of time, and means for obtaining an average of said count samples.
Claim 6
Dependent Claim
34 words
The arrangement of claim 1 wherein said directing means includes overflow detecting means producing signals indicating said incapacity of said auxiliary counter means to count further signals in said one direction or the other.
Claim 7
Dependent Claim
19 words
The arrangement of claim 1 wherein said main counter means includes a visual display of said count contained therein.
Claim 8
Dependent Claim
27 words
The arrangement of claim 1 wherein said signal source is a position transducer producing pulses corresponding to movement of a probe in a forward or reverse direction.
