Abstract

Disclosed is a system, method, and device for detecting non-nutritive sucking events produced by an infant; patterns comprising such events (i.e., rhythmic sucking patterns, or RSPs); and relating said events and/or RSPs to performance of a disposable absorbent article worn by the infant. The frequency and/or amplitude and/or other characteristics of non-nutritive sucking changes in response to liquid insults introduced to a disposable absorbent article. Accordingly, changes to RSPs offer detectable and measurable indicia of an infant'"'"'s perception of the performance of a disposable absorbent article. Furthermore, such information may be used to support and/or substantiate marketing communications to consumers, or to guide selection and/or management of research-and-development programs.

Claims

1. A system for evaluating a disposable article, the system comprising:

a first sensor adapted to detect non-nutritive sucking events produced by an infant;

a second sensor adapted to detect fluid flowing to, or present in, a disposable article worn by the infant; and

an information device operatively connected to the first sensor, said information device adapted to accomplish one or more of receiving, storing, processing, displaying, or transmitting information corresponding to a change in the non-nutritive sucking events detected by the first sensor in response to the second sensor detection.

2. The system of claim 1 wherein the first sensor is a pressure transducer adapted to detect the non-nutritive sucking events.

3. The system of claim 2 wherein the pressure transducer is attached to a pacifier.

4. The system of claim 1 wherein the information device comprises a storage device.

5. The system of claim 1 wherein the storage device is RAM, ROM, PROM, EPROM, or RFID.

6. The system of claim 5 wherein the information device is attached to a pacifier.

7. The system of claim 1 wherein the information device is a computer.

8. The system of claim 1 wherein the second sensor is adapted to detect temperature;

humidity;

current;

mass flow rate;

volumetric flow rate;

mass;

volume;

opacity;

transmittance;

wavelength;

the presence and/or concentration of dissolved solids, chemical compounds, ionic compounds, proteins, bacteria, microorganisms, suspended solids, or precipitates;

or some combination of these.

9. A message adapted to be communicated to consumers, wherein the message comprises information produced using the system of claim 1.

10. The system of claim 1 wherein a second information device is operatively connected to the second sensor, said second information device adapted to accomplish one or more of receiving, storing, processing, displaying, or transmitting information corresponding to the second sensor'"'"'s detection of fluid flowing to, or present in, the disposable article.

11. The system of claim 1 wherein the information device is operatively connected to the first sensor by conductive wire, a pneumatic connection, a hydraulic connection, a connection using a portion of the electromagnetic spectrum, or some combination of these.

12. A pacifier adapted to detect non-nutritive sucking events, the pacifier comprising:

a nipple;

a base attached to said nipple;

a sensor attached to said base, said sensor adapted to detect non-nutritive sucking events produced by an infant sucking on the nipple; and

an information device attached to said base and operatively connected to the sensor, said information device adapted to accomplish one or more of receiving, storing, processing, displaying, or transmitting information corresponding to the non-nutritive sucking events detected by the sensor;

said information comprises a psychological state of the infant as indicated by the non-nutritive sucking event detected by the sensor;

wherein the information device comprises a display adapted to present a graphical image corresponding to said psychological state.

13. The pacifier of claim 12 wherein the sensor is a pressure transducer adapted to detect non-nutritive sucking events.

14. The pacifier of claim 12 wherein the information device comprises a storage device.

15. The pacifier of claim 14 wherein the storage device is RAM, ROM, PROM, EPROM, or RFID.

16. A message adapted to be communicated to consumers, wherein the message comprises information produced using the device of claim 12.

17. A method for evaluating the performance of a first disposable article, the method comprising:

(a) detecting non-nutritive sucking events produced by an infant wearer of the first disposable article;

(b) detecting fluid flowing to, or present in, the first disposable article worn by the infant; and

(c) relating the detected non-nutritive sucking events to the detected flow of fluid to, or presence of fluid in, the first disposable article.

18. The method of claim 17 further comprising:

repeating steps 17(a), 17(b), and 17(c) for a second disposable article; and

comparing the relationship obtained for the first disposable article to the relationship obtained for the second disposable article, or

comparing the detected non-nutritive sucking events produced by an infant wearer of the first disposable article to the detected non-nutritive sucking events produced by an infant wearer of the second disposable article, or

comparing the detected fluid flowing to, or present in, the first disposable article worn by the infant to the detected fluid flowing to, or present in, the second disposable article worn by the infant, or

some combination of these.

19. The method of claim 17 further comprising communicating a message based on said relationship to consumers.

20. The method of claim 18 further comprising communicating a message based on said comparison to consumers.

21. A research-and-development method directed to changing the functional performance, product specifications, or materials of construction of a disposable article, wherein said research-and-development effort comprising the steps of evaluating non-nutritive sucking events and correlating said events with the functional performance, product specifications, or materials of construction of the disposable article.

22. A system for evaluating a disposable article, the system comprising:

a first sensor adapted to detect non-nutritive sucking events produced by an infant;

a second sensor adapted to detect a property of one or more components of the disposable article worn by the infant; and

an information device operatively connected to the first sensor and the second sensor, said information device adapted to accomplish one or more of receiving, storing, processing, displaying, or transmitting information corresponding to the non-nutritive sucking events detected by the first sensor in response to a property of one or more components of the disposable article worn by the infant as detected by the second sensor.

23. A method for evaluating the performance of a disposable article, the method comprising:

(a) detecting non-nutritive sucking events produced by an infant wearer of the disposable article;

(b) characterizing a change the disposable to a disposable article worn by the infant; and

(c) relating the detected non-nutritive sucking events to the characterized change to the disposable article.
