Apparatus and method for product and signaling device matching
View Patent ↗The present subject matter relates to absorbent articles and signaling devices for use therewith. The signaling device includes one or more non-invasive sensors configured to detect the presence of a substance, such as a body fluid, in the absorbent article. The signaling device can provide an audible and/or visible alert to the user of the absorbent article when it detects the presence of a substance. The absorbent article includes one or more identifiable characteristics the presence of which permits operation of the signaling device. In this manner, the present disclosure provides for product and signaling device matching for use.
1. A method of matching a signaling device with an absorbent article, the method comprising:
placing a signaling device on an absorbent article, the signaling device comprising a first non-invasive sensor configured to detect the presence of a substance in the absorbent article and a second non-invasive sensor;
detecting the presence of one or more identifiable characteristics on the absorbent article using the second non-invasive sensor;
activating the first non-invasive sensor when the second non-invasive sensor detects the presence of the one or more identifiable characteristics of the absorbent article;
wherein detecting the presence of one or more identifiable characteristics comprises detecting the presence of one or more predefined colors on the absorbent article.
2. The method of claim 1 , wherein the one or more predefined colors are printed in a circular pattern.
3. The method of claim 1 , wherein the one or more predefined colors are printed with the color Orange Pantone #165U.
4. The method of claim 1 , wherein the one or more predefined colors are part of a graphic printed on the absorbent article as part of a design scheme for an attachment zone for assisting with the alignment of the signaling device.
5. The method of claim 1 , wherein the second non-invasive sensor comprises a colorimeter sensor.
6. The method of claim 1 , wherein the colorimeter sensor comprises one or more photodiodes.
7. The method of claim 1 , wherein the method comprises illuminating the one or more predefined colors on the absorbent article with a light emitting diode (LED) located on the signaling device.
