Abstract: A monitoring apparatus (50) monitors heart activity by sensing one or more signals accessible at an outer skin surface of a person (100). The monitoring apparatus (50) includes one or more electrodes for contacting onto the outer skin surface of the person (100), a signal processing arrangement (108) for processing one or more signals provided from the one or more electrodes to generate corresponding processed signals, and a display arrangement (106) for receiving the processed signals to generate presentation information from which a heart beat rate of the person (100) is discernible. The signal processing arrangement includes a detector for detecting signal artefacts arising from one or more electronic devices coupled to the person (100) and for removing an influence of the signal artefacts from the processed signals, such that the processed signals provide a more accurate indication of the heart beat rate.

Abstract: 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.

Abstract: The invention relates to a sensor (42) placed on the skin, which can advantageously be integrated in a garment and has a contact layer in contact with the skin containing conductive fibres for receiving signals and a moisture retentive moisture layer (41) on top of the contact layer.

Abstract: A heart rate measuring arrangement for controlling a recovery exercise of a person from a fitness exercise which measures the heart rate, forms control information, and displays the formed control information so that the recovery exercise is performed at a controlled heart rate level.

Abstract: The invention presents a system for confirming a performer of a fitness exercise. The system includes a heart rate monitor (104) for measuring heart rate parameters (404A to 404N) associated with the fitness exercise from the heart rate of the performer. The system also includes a mathematical model (406) including dependence information between heart rate parameters (404A to 404N) and classes classifying the performer in classes (402A to 402N) such as age or weight. Heart rate parameter data measured from the performer and information in the mathematical model are utilized in identifying the performer of the fitness exercise.

Abstract: A heart rate measuring arrangement which comprises measuring means (410A to 410B) for measuring heart rate information, forming means (452) for forming an assessment of the lactate concentration in the body on the basis of the measured heart rate information, and presenting means (450) for presenting the formed assessment of the amount of lactate in the body.

Abstract: The invention relates to a telemetric measuring method and system. In the method, different sensors are used to measure at least two different variables, i.e. heartbeat, the speed and pedalling cadence of a bicycle. The measurement data on each measured variable is transferred by means of telemetric data transmission to the same receiver unit. The invention is characterized in that in the telemetric data transmission to the receiver unit, the transmission pulse groups included in the measurement data on a single measure variable comprise, in the transmission pulse group, at least two intervals. The intervals are formed between at least three identifier pulses, the combination of which is specific to the particular measure variable.
