  • Method and apparatus for low speed estimation
    Patent number: 4885710
    Abstract: A system and method determines the rotational speed of a rotating member by determining speed from signals having a frequency directly proportional to the rotational speed. The system provides for the estimation of rotational speed even if no speed signals are detected over a sampling interval.

  • Method and apparatus for detecting rotational speed
    Patent number: 4799178
    Abstract: A system and method for determining the rotational speed of a rotating member is described that determines speed from signals having a frequency directly proportional to the rotational speed. The speed signals are counted during each of successive sampling intervals. At the end of each sampling interval, the rotational speed is determined based on a calculation interval that is the time interval from the next-to-last speed signal generated in the prior sampling interval to the last speed signal generated and the number of speed signals occurring in the calculation interval. The resulting overlapping calculation intervals minimize the influence of one speed signal on successive determinations of rotational speed.
