Pulse meter and its control method you want to give the wrist

摘要

The pulsometer (10) has an electronic optical measurement device (18) measuring a pulse of a wearer and comprising light sources (E1-E3) and receivers (R1-R3). The sources are formed by a diode emitting light in infrared range, and the receivers are formed by photodiodes. The sources and the receivers are arranged in the form of a matrix including rows and columns (C1-C3). The rows are oriented along a direction orthogonal to a direction of a wrist, and the columns are oriented parallel to the direction of the wrist. Each row and column alternately contains one light source and one receiver. An independent claim is also included for a method for controlling a pulsometer.
