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.

This disclosure relates generally to methods and systems for determining whether at least a first component and a second component of a personal protection (PP) configuration are compatible so as to be assembled into an approved PP configuration, responsive to being compared against at least one predetermined criterion. Included is a smart tag for each of the first and second components. The first and second smart tags include respective first and second data. A data acquiring system is provided for acquiring the first and second data and a data processing system processes the acquired first and second data for determining if the first and second components are compatible to be assembled as an approved PP configuration.

Determining compatibility of components for assembling approved personal protection configurations

A respiratory component system including a respiratory component and a wearable belt is described. The respiratory component includes a projection, and the wearable belt is configured to receive the projection to releasably secure the respiratory component to the wearable belt.

Interlock system for a respirator waist belt

A wearable belt for supporting a respiratory component is disclosed. The belt includes a first end portion, a second end portion, and an interface portion that includes an inner layer, an outer layer, and a rigid attachment element in contact with the inner layer and the outer layer. The rigid attachment element is configured to mate with a corresponding feature of a respiratory component.

The present invention relates to a fan-forced positive pressure breathing apparatus commonly known as a Powered Air Purifying Respirators (PAPR) system, and specifically concerns the connecting of the breathing components of such equipment. The invention is a method and apparatus for rapid engagement of PAPR breathing components (such as air supply lines and filter elements to a blower housing). The invention also provides for indicating and/or monitoring whether the relative components have been aligned and coupled in sealed engagement.

Apparatus and method for breathing apparatus component coupling

A cassette for use in an electronic radiographic imaging system having electronic components. The cassette includes a positioned photoreceptive medium, a light-tight frame, at least one power storage device, and an electronic interface structure for connection to electronic components within the radiographic imaging system. The cassette can also include an electrical interface structure for connection to a power source within the radiographic imaging system.

Cassette for use in an electronic radiographic imaging system

A radiographic image reader acquires electronic signals corresponding to a latent image of an object produced by radiation exposure of a photoreceptive medium within a cassette. The radiographic image reader comprises a light-tight enclosure with at least one access port for inserting and removing the cassette. A scanner subsystem is mounted within the light-tight enclosure for scanning the photoreceptive medium within the cassette to initiate the acquisition of the electronic signals representative of the latent image. A cassette registration and interface subsystem within the light-tight enclosure comprises an electronic interface structure for electronically connecting the photoreceptive medium within the cassette to an electronic component external of the cassette to obtain the electronic signals corresponding to the latent image.
