Abstract: A method of varying the phase spacing of sequential ignition pulses emitted by an ignition pulse transducer and an apparatus for performing the method are proposed, in which with the aid of a phase control circuit a corrected ignition control pulse train of average frequency is formed on the basis of an actual ignition control pulse train. The corrected pulse train being held constant so long as a given phase difference is maintained between the two control pulse trains. As a result, brief rpm fluctuations, which in an rpm range in the vicinity of idling rpm are perceived as jerking, are compensated for. When there are changes in rpm which cause larger phase deviations, the corrected ignition control pulse train is synchronized with the actual ignition control pulse train.

Abstract: Disclosed is a monitor apparatus which can be worn by a patient and will provide an indication of activity levels over a number of subsequent time periods. A transducer which is energized by the ambulatory subject's movement, provides an activity pulse into a temporary memory. At the end of a standard timing interval, for example fifteen (15) minutes, a digital code word representative of the total number of activity pulses in that standard timing interval is fed into a solid state memory. The temporary memory is then reset and counts the activity pulses over the next standard timing interval. In this manner, activity levels for any number of sequential time intervals can be recorded without hindering the patient's movement. A contol logic circuit, which is externally triggered, causes the permanent memory to sequentially readout the activity levels of subsequent standard timing intervals for use in studying the activity levels of ambulatory subjects.
