摘要： An absorbent article (10) includes a backsheet layer (30), a liquid permeable topsheet layer (28), and an absorbent body (32) sandwiched between the backsheet and topsheet layers. The absorbent body (32) includes a first fibrous stratum (52) having a first quantity of absorbent fibers, a second fibrous stratum (54) having a second quantity of absorbent fibers, and at least a third fibrous stratum (56) which is located between and integrally formed with the first and second fibrous strata (52, 54). In particular aspects, the third fibrous stratum (56) includes an operative quantity of a substantially hydrophilic, wet-strength agent. In other aspects, the wet-strength agent is distributed in the third quantity of absorbent fibers to render the third fibrous stratum (56) substantially non-dispersible.

摘要： A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the product as possible, while providing optimum intake performance through appropriate control of the composite properties. The low saturation in this layer provides void volume for the incoming insult as well, as a high permeability, thus increasing the intake rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide an appropriately high level of capillary tension to provide enough control of the liquid to stop leakage from occurring. This low saturation layer is used in addition to a surge material and provides intake functionality in addition to that provided by the surge material. In particular aspects of the invention, the body side layer of the absorbent core does not extend over the entire surface of the overall absorbent core, therefore is not used as the high saturation, wicking layer, but as the intake layer. This arrangement also allows the intake layer to be in direct contact with the incoming liquid, therefore allowing for more immediate access and improved intake function. In additional aspects, at least one primary layer region can have a non-uniform, selectively zoned basis weight distribution. Particular configurations of the at least one primary layer region can be constructed with a target area of such primary layer region having a basis weight which is less than a basis weight of another non-target portion of the primary layer region. Moreover, at least one primary layer region can have a heterogeneous structure. In particular constructions, the at least one primary layer region can include a plurality of two or more sublayers.

摘要： In one aspect a drug delivery device may include a reservoir containing a liquid drug formulation and a microneedle assembly in fluid communication with the reservoir. The microneedle assembly may include a plurality of microneedles, with each microneedle defining an open channel for receiving a drug formulation. The open channel may have a normalized hydraulic radius ranging from about 0.1 to about 0.8. The open channel may also have a Iiquid-to-solid interfacia! energy and a liquid-to-vapor interfacia! energy when a fixed volume of the drug formulation is received therein. In addition, the drug formulation and a cross-sectional geometry of the open channel may be selected and configured such that the liquid- to-solid energy exceeds the liquid-to-vapor energy as the length of the fixed volume of drug formulation is increased within the open channel.

摘要： Embodiments of the invention provide methods and systems for determining hydration of an article and/or a person. The physical and/or electrical properties of a device in the absorbent article may be altered by hydration received in the absorbent article. The alteration of the physical or electrical properties may indicate the amount of hydration in the absorbent article. Furthermore, a time period for receiving the hydration in the absorbent article may also be determined. The hydration of the person may be determined based on a fluid output rate from the person computed using the amount of hydration output from the person and the time period for receiving the hydration.

摘要： A chemical gas sensor formed from a nonwoven material is described. The gas sensor includes a flexible, gas-permeable, nonwoven web-based material substrate having a matrix that is composed of a plurality of inert thermoplastic, pulp, cellulose or staple fibers as either a major or minor portion, with a plurality of gas-sensitive fibers formed from a polymer that can absorb volatile organic compounds (VOC), and a plurality of electrically conductive fibers. The gas- sensitive fibers are intermixed with and associated spatially among a network of adjacent electrically conductive fibers, such that a change in physical morphology of said gas-sensitive fibers as a result of interacting with volatile organic compounds, causes a change in dielectric properties that disrupts said network of adjacent electrically conductive fibers. The sensor can be configured as either a resistive or a capacitive chemisensor.

摘要： A radiating element made from a conductive-nonwoven web is incorporated into a signal emitting apparatus. The signal emitting apparatus, for instance, may comprise an RFID tag. The conductive-nonwoven web contains, in one embodiment, conductive fibers combined with pulp fibers. The conductive fibers may comprise carbon fibers. The nonwoven web may be made using a conventional paper-making process. The resulting conductive web is not only well suited for use as an antenna, but is also relatively inexpensive to manufacture and can be easily incorporated into numerous products.

摘要： Embodiments of the invention relate to an image analysis system for detecting compliance with requirements for using personal protective equipment (PPE). An image capturing device may be used to acquire an image of an individual requesting entry into a restricted area. In turn, a PPE 5 analysis tool may be configured to analyze the image to detect the presence of the PPE, e.g., by recognizing markings made using UV fluorescent dye, reflective ink, or other marking materials visible in the captured image and/or the physical shape of the PPE. The image analysis tool may be further 10 configured to demine not only whether the required PPE is present, but also determine whether the PPE is being worn correctly by the individual requesting access to the restricted area.
