Air supply attachment for a helmet

In some examples, a system () includes a hearing protector (); at least one position sensor; at least one sound monitoring sensor; at least one computing device configured to: receive, from the at least one sound monitoring sensor and over a time duration, indications of sound levels to which a worker is exposed; determine, from the at least one position sensor and during the time duration, that the hearing protector is not positioned at one or more ears of the worker to attenuate the sound levels; and generate, in response to the determination that at least one of the sound levels satisfies an exposure threshold during the time duration and the hearing protector is not positioned at one or more ears of the worker to attenuate the sound levels, an indication for output.

Hearing protector with positional and sound monitoring sensors for proactive sound hazard avoidance

A pleated filter element comprising a pleated filter media comprising a plurality of oppositely-facing pleats with a pleat direction and with a plurality of upstream and downstream pleat tips and pleat valleys, wherein the pleated filter media comprises two corrugated edges and two noncorrugated edges. The first (second) corrugated edge of the pleated filter media comprises an edge dam of hardened adhesive that occupies the upstream and downstream pleat valleys at a location laterally inwardly proximate the first (second) corrugated edge and that extends along an entire longitudinal extent of the pleated filter media. The pleated filter media is a multilayer media comprising an organic polymeric nonwoven web, that exhibits a Percent Penetration of less than 5, laminated with a fiberglass prefilter layer that is disposed upstream of the primary filtration layer and that exhibits a Percent Penetration of greater than about 70.

Pleated filter element comprising pleated filter media with edge dams, and method of making and using

An article comprising at least one microneedle is provided. The article can comprises a first side and a second side opposite the first side. The first side comprises a central cavity portion and a platform portion, with at least one microneedle extending therefrom, wherein the platform portion is not coplanar with the central cavity portion. The platform portion substantially surrounds the central cavity portion. The at least one microneedle comprises a body comprising an outer surface; a base segment having a base and a first shape; a tip segment having a tip and a second shape, wherein the second shape is distinct from the first shape; a transition plane that delineates the base segment and the tip segment; and a central axis. Methods of using the article are also provided.

Provided acoustic devices include an external housing defining an expansion chamber and a wall extending through and partitioning the expansion chamber into a central chamber and a peripheral chamber adjacent the central chamber, wherein an inlet and outlet communicate with the central chamber, and wherein the wall includes a plurality of apertures formed therethrough to allow air movement to and from the central and expansion chambers, the plurality of apertures sized to provide an average flow resistance ranging from 100 MKS Rayls to 5000 MKS Rayls. The acoustic devices advantageously show significant sound attenuation while streamlining air flow to reduce pressure drop across the expansion chamber.

Acoustic device

An article having at least one microneedle () is provided. The microneedle includes a base (), an elongated body () having a central axis () and a body diameter (), a tip portion (), and a hollow channel (). The a tip portion includes a tip (), a first bevel face () oriented diagonally with respect to the central axis and extending through at least 75% of the body diameter, a second bevel face () oriented substantially perpendicular to the central axis and intersecting the first bevel face, and a bevel opening defined by a first edge () of the first bevel face and a second edge () of the second bevel face. The hollow channel extends axially into the body from the bevel opening ().

Hollow microneedle with beveled tip

An articlecomprising at least one microneedleis provided. The article comprises a first sideand a second sideopposite the first side. The first side comprises a central cavity portionand a platform portion, with at least one microneedle extending therefrom, wherein the platform portion is not coplanar with the central cavity portion. The platform portion substantially surrounds the central cavity portion. The at least one microneedlecomprises a body comprising an outer surface; a base segmenthaving a base and a first shape; a tip segmenthaving a tipand a second shape, wherein the second shape is distinct from the first shape; a transition planethat delineates the base segment and the tip segment; and a central axis.

Article comprising a microneedle

An articlehaving a first sidethat has a central portiondefined by a first edge, a microneedle-free peripheral portionthat substantially surrounds the central portion, and a plurality of spaced-apart hollow microneedles. Each microneedle has a body that includes an outer surface; a base segmenthaving a baseand a first shape; a tip segmenthaving a tipand a second shape, wherein the second shape is distinct from the first shape; a transition planethat delineates the base segment and the tip segment; and a central axis. An angle, defined by an intersection of the central axis of at least one microneedle and a shortest line extending from the first edge and through the transition plane of the at least one microneedle, is less than about 50&#xb0;.

An eyewear article having a flexing portion including first and second longitudinally disposed ribs is disclosed. In another exemplary embodiment, the flexing portion has a maximum height (H), in a direction parallel to a mid-sagittal plane bisecting the eyewear into imaginary left and right halves, that is greater than 10 mm. The eyewear article of the present invention provides a balance of fit and comfort suitable for a range of user head sizes.

Eyewear having a flexural member

A heatsink for use in injection molding, with at least one load-bearing path with a rearward segment, wherein at least a portion of at least one non-load-bearing, dynamic heat-transfer zone of the heatsink is laterally offset from the rearward segment of the load-bearing path.
