Abstract

A method of monitoring an absorption state of an absorbent article includes providing a logger unit, acquiring the absorption state of the absorbent article, and recording data indicating the acquired absorption state of the absorbent article in the logger unit. Acquiring the absorption state of the absorbent article and recording the data indicating the acquired absorption state of the absorbent article in the logger unit are each continuously performed during a monitoring period of the absorbent article. Also disclosed is a logger unit for performing this method; and a method of processing data indicating an absorption state of an absorbent article, which includes receiving sets of data indicating the absorption state of the absorbent article. Each of the sets of data indicates the absorption state of the absorbent article over a portion of a continuous period of time, and collating and/or displaying the data in continuous form. Also disclosed are data processing units for performing these data processing methods.

Claims (44)

1. A method of monitoring an absorption state of an absorbent article, the method comprising

providing a logger unit;

acquiring the absorption state of the absorbent article;

recording data indicating the acquired absorption state of the absorbent article in the logger unit; and

determining whether data indicating the acquired absorption state of the absorbent article has been recorded in the logger unit throughout the entire monitoring period,

wherein acquiring the absorption state of the absorbent article and recording the data indicating the acquired absorption state of the absorbent article in the logger unit are each continuously performed during a monitoring period of the absorbent article.

2. The method according to claim 1 , wherein the absorbent article has one or more sensor elements;

wherein acquiring the absorption state of the absorbent article is performed by the one or more sensor elements; and

wherein providing the logger unit comprises connecting the logger unit to the one or more sensor elements.

3. The method according to claim 1 , further comprising transmitting the data recorded in the logger unit to a location remote of the logger unit.

4. The method according to claim 3 , wherein the data recorded in the logger unit is transmitted to the location remote of the logger unit in preset intervals.

5. The method according to claim 1 , further comprising marking the data recorded in the logger unit as inaccurate if it is determined that data indicating the acquired absorption state of the absorbent article has not been recorded in the logger unit throughout the entire monitoring period.

6. The method according to claim 1 , further comprising an interpolation process if it is determined that data indicating the acquired absorption state of the absorbent article has not been recorded in the logger unit throughout the entire monitoring period,

wherein the interpolation process comprises interpolating values for the absorption state in the time interval or intervals in which no data indicating the acquired absorption state of the absorbent article has been recorded in the logger unit, on the basis of the data recorded in the logger unit.

7. The method according to claim 1 , wherein the absorption state includes at least one of the group consisting of: the amount of liquid absorbed in the absorbent article; the volume of liquid absorbed in the absorbent article; the point in time at which liquid absorption in the absorbent article has started to occur; the point in time at which liquid absorption in the absorbent article has stopped to occur; the duration over which liquid absorption in the absorbent article has occurred; and the distribution of absorbed liquid in the absorbent article.

8. The method according to claim 1 , further comprising establishing an absorption pattern on the basis of the data recorded in the logger unit.

9. The method according to claim 1 , further comprising displaying the data recorded in the logger unit in continuous form.

10. A logger unit for monitoring an absorption state of an absorbent article, comprising

a processor configured to acquire the absorption state of the absorbent article; and

a memory configured to record therein data indicating the acquired absorption state of the absorbent article,

wherein the processor and memory are configured to acquire the absorption state of the absorbent article and record the data indicating the acquired absorption state of the absorbent article in the logger unit continuously during a monitoring period of the absorbent article, and

wherein the processor and memory are configured to determine whether data indicating the acquired absorption state of the absorbent article has been recorded in the logger unit throughout the entire monitoring period.

11. The logger unit according to claim 10 , wherein the logger unit is configured to be deactivated when it is removed from the absorbent article.

12. The logger unit according to claim 10 , wherein the logger unit is configured to transmit the data recorded therein to a location remote of the logger unit.

13. A combination comprising the logger unit according to claim 10 and an absorbent article.

14. The combination according to claim 13 , wherein the absorbent article comprises one or more sensor elements;

wherein the logger unit is connectable to the one or more sensor elements; and

wherein the processor of the logger unit is configured to acquire the absorption state of the absorbent article from the one or more sensor elements.

15. A method of processing data indicating an absorption state of an absorbent article, the method comprising

receiving sets of data indicating the absorption state of the absorbent article, wherein each of the sets of data indicates the absorption state of the absorbent article over a portion of a continuous period of time; and

displaying the sets of data in continuous form for the entire continuous period of time.

16. A method of processing data indicating an absorption state of an absorbent article, the method comprising

receiving sets of data indicating the absorption state of the absorbent article, wherein each of the sets of data indicates the absorption state of the absorbent article over a portion of a continuous period of time; and

collating the sets of data so as to obtain a single set of data indicating the absorption state of the absorbent article over the continuous period of time, wherein the single set of data includes portions of the continuous period of time in which no indication on the absorption state of the absorbent article is provided.

17. The method according to claim 16 , further comprising displaying the single set of data in continuous form.

18. A data processing unit for processing data indicating an absorption state of an absorbent article, comprising:

a processor configured to receive sets of data indicating the absorption state of the absorbent article, wherein each of the sets of data indicates the absorption state of the absorbent article over a portion of a continuous period of time; and

a display configured to display the sets of data in continuous form for the entire continuous period of time.

19. The data processing unit according to claim 18 , further comprising a display configured to display time intervals in the data in which no indication on the absorption state of the absorbent article is provided.

20. The data processing unit according to claim 18 , further comprising a display configured to display the number of segments of the absorbent article which have absorbed liquid.

21. A data processing unit for processing data indicating an absorption state of an absorbent article, comprising a processor

configured to receive sets of data indicating the absorption state of the absorbent article, wherein each of the sets of data indicates the absorption state of the absorbent article over a portion of a continuous period of time; and

configured to collate the sets of data so as to obtain a single set of data indicating the absorption state of the absorbent article over the continuous period of time, wherein the single set of data includes portions of the continuous period of time in which no indication on the absorption state of the absorbent article is provided.

22. The data processing unit according to claim 21 , further comprising a display configured to display the single set of data in continuous form.
