Patent ID: 8021297

Claim:
A wearable device comprising: at least two measuring devices that provide primary data, a processor programmed to: calculate secondary data from the primary data, calculate reference data from the primary and/or secondary data, and compare the reference data with at least two specific data patterns, each data pattern corresponding to a predefined activity such that the comparing of the reference data to the data patterns automatically recognizes the corresponding predefined activity, the predefined activities including at least three of: jogging and the specific data pattern assigned to jogging comprises a heart rate with variations over jogging time intervals, a velocity varying between 7 km/h and 25 km/h, a periodic vertical acceleration and a constant step frequency, cycling and the specific data pattern assigned to cycling comprises a heart rate unvarying within cycling time intervals, a velocity varying between 10 km/h and 90 km/h, a discrete horizontal acceleration, and no step frequency, a water sport and the specific data pattern assigned to the water sport comprises a heart rate with variations over a water sport variation range and water sport time intervals, a velocity below 20 km/h, periodic accelerations, above normal skin humidity, and no step frequency, a ball game and the specific data pattern assigned to the ball game comprises a varying heart rate, a velocity varying between 0 km/h and 30 km/h, a varying horizontal and vertical acceleration during defined ball game time intervals, a strongly varying step frequency, and a fitness sport and the specific data pattern assigned to the fitness sport comprises a heart rate with first variations within a first fitness sport variation range and first fitness sport time intervals, a velocity below 5 km/h, a periodically varying horizontal and vertical acceleration during a second fitness sport time interval range and a varying step frequency within a second fitness sport variation during the second fitness sport time intervals; and a memory that stores the primary data, the secondary data and the at least two specific data patterns.
