Abstract: A portable electronic device comprises a controller and a display. The controller receives vector data on a position of a user of the portable device from a satellite positioning sensor associated with the user, and scalar data on movement of the user from at least one motion sensor associated with the user. The controller stores data based on the vector data and feeds a scalar parameter proportional to the scalar data to the display. The display displays the scalar parameter.

Abstract: The invention relates to a measuring device (102) carried by a user during exercise for measuring non-invasively at least one signal from the body, e.g. a wireless heart rate monitor, and to a method of controlling same. The measuring device comprises a user interface (120). The user interface comprises selection means (114), e.g. push buttons (114), and display means (116, 122), e.g. a liquid crystal display. The user interface (116) displays different operating modes, e.g. a watch mode (300), a set mode (306) and an operating mode (302) for measuring a signal from the body. The operating modes are arranged as a main loop sequence (300-302-304-306). The operating modes have different sub-operating modes for displaying parameters associated with exercising. The sub-operating modes are arranged as sub-loop sequences (400-404-406-410) under each operating mode. In accordance with the invention, the user is able to configure the sub-loop sequence (400-404-406-410) by the selection means (114).

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.
