Abstract

A wrist-worn device comprising a wristband to be arranged around the wrist and an electronics unit in connection with the wristband, the electronics unit being arranged to process a value of an exercising variable relating to a physical activity, the wrist-worn device further comprising a display for showing the exercising variable value. The wristband, electronics unit and display of the wrist-worn device are integrated together to form a single, uniform wrist-worn device.

Claims

1. A wrist-worn device comprising a wristband to be arranged around the wrist and an electronics unit in connection with the wristband, the electronics unit being arranged to process a value of an exercising variable relating to a physical activity, the wrist-worn device further comprising a display for showing the exercising variable value, wherein the wristband, electronics unit and display of the wrist-worn device are integrated together to form a single, uniform wrist-worn device.

2. A wrist-worn device according to claim 1, wherein the wristband, display and electronics unit of the device are sealed and integrated together with plastic to form a uniform piece.

3. A wrist-worn device according to claim 2, wherein the wristband, display and electronics unit of the device are integrated together with plastic by injection moulding.

4. A wrist-worn device according to claim 2, wherein the portion of the device encapsulating the display is formed of transparent plastic.

5. A wrist-worn device according to claim 1, wherein one or more of the following serve as exercise variables:

the person'"'"'s heart rate, average heart rate, heart rate deviation, exercise duration from the beginning of the exercise.

6. A wrist-worn device according to claim 1, wherein the electronics unit comprises receiver means for receiving heart rate information and computing means for processing the heart rate information to show the person'"'"'s heart rate on the display.

7. A wrist-worn device according to claim 1, wherein the display is constructed onto a flexible circuit board to make the wrist-worn device flexible.

8. A wrist-worn device according to claim 1, wherein the display is a bar display comprising a string of display areas.

9. A wrist-worn device according to claim 8, wherein each display area of the display is used for showing a value range containing at least one possible exercise variable value.

10. A wrist-worn device according to claim 9, wherein the display area at a first end of the bar display is for the value range representing the lowest exercise variable value to be displayed and the display area at a second end is for the value range showing the highest exercise variable value to be displayed.

11. A wrist-worn device according to claim 9, wherein the display comprises an illumination element for at least one display area to illuminate the display area, the illumination element being arranged to illuminate the display area when a momentary exercise variable value is within the value range corresponding to the display area in question.

12. A wrist-worn device according to claim 9, wherein the value ranges on the bar display are arranged on a substantially straight line with respect to one another.
