    Abstract: The present invention relates to a sensor, system and method for detecting or sensing moisture or wetness of an article. Instead of conventional methods for detecting or sensing moisture or wetness of an article such as visual checking which requires constant inspection of the article, and for many articles is not possible, or the use of chemically activated indicators which are generally single use, the present invention uses electrical charge to detect or sense the moisture or wetness of an article. In that way, the present invention aims to provide a reusable way for detecting or sensing moisture or wetness in different articles. The present invention may be used in applications where moisture or wetness changes often.

    Abstract: A nonwoven web for an absorbent article is provided. The absorbent article comprises the nonwoven web as a core wrap. A method for producing the absorbent article is also provided. The nonwoven web comprises a first nonwoven layer comprising filament fibers, a second nonwoven layer comprising filaments fibers, a third nonwoven layer comprising staple fibers disposed between the first and second nonwoven layers. A total basis weight of the first and second nonwoven layers is not less than about 10 gsm. The third nonwoven layer has a basis weight no greater than about 4 gsm. The nonwoven web comprises pores, wherein greater than about 80% of the pores have a pore size equal to or smaller than about 40 μm, and wherein less than about 10% of the pores have a pore size equal to or greater than about 45 μm.

    Abstract: A sensor for monitoring wetness in a diaper or other absorbent article includes a housing that attaches to the absorbent article. The sensor may include inner and outer housing portions that capture an edge of the absorbent article between the housings. The sensor may include contacts that electrically connect with a pair of contact strips embedded in the absorbent article. The distance between the embedded strips may vary depending on the size of the absorbent article. The sensor may include multiple pairs of contacts that are spaced apart to match the distance between the contact strips for the variously sized absorbent articles. In this way, depending on the pair of contacts connected to the contact strips, the sensor may indicate the size of the absorbent article. The sensor may have a housing with a cavity and a lid that closes the cavity. The lid may be secured with a latch.

    Abstract: Touch-free, voice-assistant, and/or tracking systems and methods are described for automating inventory generation and tracking of childcare products. In various aspects, the touch-free, voice-assistant, and/or tracking systems and methods comprise receiving, by one or more processors, one or more name values corresponding to one or more children of a childcare program associated with at least one physical childcare location. A childcare product inventory, comprising a childcare product of at least one product type, is generated based on a count of the one or more name values. Child event data is received comprising information related to use of the childcare product. The child event data is based on audible input of a user as received via a voice command interface of a voice-assistant application (app) as implemented on a voice assistance device. The childcare product inventory may be updated based on the child event data.
