The invention relates to a portable electronic device and computer software product. The portable electronic device comprises a motion detector for generating motion data characterizing the local movement of the portable electronic device, a motion intensity determiner for determining a instantaneous motion intensity value of the user of the portable electronic device from the motion data, and an active time counter for determining an active time accumulation that sums up the time periods, during which the instantaneous motion intensity value meets predefined activity criteria.

Portable electronic device and computer software product

The invention relates to a charging method and a charging arrangement for a measuring system which measures the heart rate. The functional unit of the measuring system comprises at least a transmitter unit (100) and/or a receiver unit. The charging arrangement comprises a charging unit (340). The charging coil (320) of the charging unit is arranged to transfer electric energy inductively to the power source (302) of the functional unit (100) via an induction coil (310). The induction coil (130) of the functional unit (100) used for charging is connectable to more than one inductively active function in addition to charging.
