Abstract: Techniques for intelligently managing a virtual private network (VPN) gateway in a cloud computing system are disclosed herein. In one embodiment, an instance of a VPN gateway can query whether a logic lock on a network address is maintained by another instance via periodic renewal. In response to receiving a query result indicating that a logic lock on the network address is lost by the another instance, the instance can migrate a VPN connection originally handled by the another instance from the another instance to the instance such that a private network is connected to the instance via the migrated VPN connection to reduce downtime for accessing computing resources in the cloud computing system.

Abstract: A vehicle safety system includes a module including an airbag and an inflator. The inflator includes a housing (12) in which a combustion chamber (16) containing a pyrotechnic propellant is arranged in which hot gas is generated and which housing includes at least one escape orifice (22) toward the environment of the inflator (10), as well as a coolant reservoir (24) arranged in the housing (12) in which coolant is accommodated prior to activation of the inflator (10) and which has at least one coolant outlet orifice (28?). The coolant outlet orifice (28) is arranged in direct vicinity of the outlet orifice (22). Upon activation of the inflator (10) coolant flows out of the inflator into the protection system and wets an adjacent wall (32) of the protection system against which also the hot gas is flowing.

Abstract: A dryness indicator includes a wicking strip continuous between a reservoir end and an opposed open end; a liquid-impermeable top layer disposed on one side of the wicking strip; and a liquid-impermeable bottom layer disposed on the opposite side of the wicking strip, wherein the top layer is affixed to the bottom layer to at least partially enclose the wicking strip, and wherein the indicator is configured such that the open end of the wicking strip can be placed in liquid communication with an object or surface. The dryness indicator also includes a reservoir including an oil-based colorant with the potential to be in liquid communication with the reservoir end of the wicking strip, wherein the wicking strip is configured such that colorant wicking from the reservoir end and an unreacted water-based fluid wicking from the open end meet to define a timing line.

Abstract: A dehydration sensor having a stable, printable, buffered-ink composition that enables one to miniaturize the detection zone and permits both buffer and indicator dye to be applied in the same area of a detection zone, without need for a conventional, large buffer pad region.

Abstract: A wetness indicator material may be used on a substrate to form a wetness sensor. The sensor may show either the presence or absence of an aqueous-based fluid or water-containing medium, such as vaginal fluid or urine in a personal hygiene article. The wetness sensor may be incorporated into the article. The wetness indicator material includes a standard colorant that does not change color when wetted. The standard colorant increases the range of hues exhibited by the wetness indicator material.

Abstract: In accordance with one embodiment of the present disclosure, a method for quantitatively or semi-quantitatively determining the volume of a test sample of urine is provided. The method includes contacting the test sample with a fluidic medium of a lateral flow device having a volume indicator disposed thereon and determining the volume of urine in the test sample based on the distance traveled by the volume indicator along the fluidic medium, the distance traveled by the volume indicator corresponding to the volume of urine in the test sample.

Abstract: An absorbent article includes a chassis including a bodyside liner, an outer cover having an interior surface and an exterior surface, and an absorbent structure positioned adjacent the interior surface of the outer cover, the chassis including an insult zone and a crotch region positioned in between a front region and a back region, the front region and the back region defining a waist region therebetween. The absorbent article also includes a sensor element disposed in or on the chassis, the sensor element extending from a proximal end in the waist region to at least the insult zone and in fluid communication with the insult zone, the sensor element including a multi-layer wicking material.

Abstract: A wetness sensor for an absorbent article that is formed from an ink is provided. The ink includes a proton-accepting chromogen and a proton-donating agent (or color developer). Prior to use, the ink is generally dry and in a protonated form so that it has a visible color. However, upon contact with bodily fluids (e.g., urine, fecal matter, mucus, menses, vaginal fluid, etc.), water in the fluid can lead to deprotonation of the chromogen, thereby resulting in a shift of the absorption maxima of the chromogen towards either the red (“bathochromic shift”) or blue end of the spectrum (“hypsochromic shift”). To increase the rate of the color change during use, the proton-donating agent is an aliphatic carboxylic acid that is highly soluble in the bodily fluid (e.g., urine), and therefore results in a color change that is very rapid and may be detected within a relatively short period of time.

Abstract: The invention describes a color-developing composition that contains at least three major components: (1) a leuco dye or a combination of leuco dyes, (2) an color-developer or a combination of color-developers that can form colored complexes with the leuco dyes, and (3) a desensitizer to temporarily remove the effect of the developer so the leuco dye appears in its colorless form. An optional binder may be included so that the composition may be applied to a substrate as an ink. The ink composition may be applied to synthetic polymeric substrates and other substrates that are incorporated into absorbent articles or personal care products.

Abstract: The present disclosure relates to a color-changing composition and to a substrate having the color-changing compositions disposed thereon. The color-changing composition includes a leuco dye, a color-developer and a desensitizer. The color-changing composition changes from a colorless or largely colorless composition to color upon being wetted with an aqueous liquid. The color-changing composition remains colorless or largely colorless prior to exposure to high relative humidity conditions.
