First Claim
Patent Images
1. A method for testing a rotary movement-electrical signal transducer system of the type generating a series of signals during operation thereof, comprising the steps of:
- receiving said signals;
measuring the time of each of said signals to establish the periods therefor;
comparing said periods to determine a maximum period and a minimum period thereof;
determining an average period for said periods;
comparing said average period to said minimum period and said maximum period to provide a first evaluation interval and a second evaluation interval, respectively;
generating a reference interval;
comparing said reference interval to said first evaluation interval and said second evaluation interval; and
generating a postive test signal whenever said first evaluation interval and said second evaluation interval are less than said reference interval.

2. An apparatus for testing a rotary movement-electrical signal transducer system, said system providing a series of pulses during operation thereof, comprising:
-
input means coupled to said system for receiving said pulses; means for measuring the time of each of said pulses to establish a series of periods relted to said pulses; processor means for receiving said series of periods and for determining therefrom a miximum, minimum and average of said periods, said processor means calculating a first evaluation interval from said minimum and said average and a second evaluation interval from said maximum and said average; said processor means further generating a reference interval and comparing said first evaluation interval and said second evaluation interval thereto, said processor means transmitting a positive test signal whenever said first evaluation interval and said second evaluation interval are less than said reference interval; and
output means for displaying said positive test signal. - View Dependent Claims (3, 4, 5)
