ИСТИНА

Systems and methods for counting features in a motion signal are provided. An example method includes detecting a signal indicative of a motion of a human body, determining, by a controller communicatively coupled to the sensor, a period in the signal, determining a location and a value of a feature within the period of the signal, determining that the location and the value of the feature are valid for counting, and in response to the determination that the location and the value of the feature are valid for counting, increasing a counter for the feature. The feature may also include a global maximum of the signal within a positive phase of the period. Criteria for the validation depend on a current type of activity. The method includes automatically determining the current type of activity based on several preceding locations and values of the feature in the signal.
