Abstract: A blower/filtration unit for a powered air purifying respirator (PAPR) is presented that includes a motor configured to operate in a standard mode and in a high magnetic field (HMF) mode. The unit also includes a magnetic field sensor. The unit also includes a controller comprising a control mode switching function. The controller executes the control function upon detection of a magnetic field strength that exceeds a reference threshold magnetic field strength. The control function switches the motor operation from the standard mode to the HMF mode.

Abstract: A blower/filtration unit for a powered air purifying respirator (PAPR) includes a motor configured to operate according to a motor control algorithm. The blower/filtration unit also includes a first pressure sensor positioned at an inlet of the blower/filtration unit. The blower/filtration unit also includes a second pressure sensor positioned at an outlet of the blower/filtration unit. The blower/filtration unit also includes a motor controller that executes the motor control algorithm. The motor control algorithm determines a motor speed required to maintain an airflow rate based on signals from the first and second pressure sensors.

Abstract: A breathing apparatus includes a blower unit including a blower. The breathing apparatus further includes a battery pack including at least one electrochemical cell. The breathing apparatus further includes an adaptor including an adaptor housing physically connected to the blower unit and the battery pack. The adaptor further includes electrical contacts that engages with corresponding electrical terminals of the blower unit and the battery pack, such that the blower is electrically coupled to the electrochemical cell. The adaptor further includes at least one communication interface for receiving data from at least one of the blower unit and the battery pack, and transmitting data to an external device.

Abstract: 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.

Abstract: 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.
