Abstract

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.

Embodiment Construction

[0024] 1 to 4 show a pulsometer 10 that can be worn on the wrist 12 of a wearer. Pulsometer 10 includes a housing 14 connected to wrist 12 via a fastening wrist strap or strap 16 .

[0025] In the following description, the general direction with respect to the forearm of the wearer's wrist 12 is designated as direction D1.

[0026] The housing 14 comprises electro-optical means 18 for measuring the pulse of the wearer and electronic circuitry 20 for processing the measurements in order to calculate and display the wearer's pulse P by means of a display means 22, such as a liquid crystal display.

[0027] The electro-optic measurement device 18 is disposed within the rear cover 24 of the housing 14 , on the opposite side from the display device 22 . The wrist strap 16 holds the back cover 24 of the housing 14 pressed against the wrist 12 so as to optimize the operation of the electro-optical measuring device 18 .

[0028] According to the teachings of the present invention, ...
