Abstract: Systems, methods, and devices for an end of service life indicator for a respirator are described herein. For example, a device can include a cartridge containing a filter material and an insert extending through at least a portion of the filter material having a first path with a first opening to provide a sample of air that is representative of a saturation of the filter material and a second path with a second opening configured to provide a filtered sample of the air throughout a service life of the cartridge.

Abstract: Disclosed are methods and systems for detecting a target gas, which involve a configuration of a light source (120) and paper tape (110) such that light (112) emitted from the light source (120) can transmit through the paper tape (110). At least some of the portion of light (112) which transmits through a paper tape (110) can be detected with a detector (130). Detection of the light (112) can be used to determine presence or absence of low concentrations of the target gas.

Abstract: Disclosed herein are methods and systems for distinguishing a target gas from other target gases, which involve a configuration of a light source (120) and paper tape (110) such that light (112) emitted from the light source (120) can reflect off the paper tape (110). A reflected portion (114) of the light (112) can be detected, as well as the humidity and optionally the temperature. The light (112) can emit in at least three wavelengths selected from red, green, blue, and ultra-violet wavelengths, and pattern recognition can be used to identify and/or distinguish the target gas from the group of target gases based on wavelength detection information and the one or more of the humidity and the temperature.

Abstract: Embodiments relate generally to systems and methods for determining end of service life for a respirator cartridge by comparing the gas levels sensed at two or more sample points within the cartridge. Sample streams may run from the sample points to a gas sensor, wherein a valve may control the flow between the sample streams and the gas sensor.

Abstract: Disclosed herein are methods and systems for distinguishing a nuisance gas from a target gas or group of target gases, which involve a configuration of a light source (120) and paper tape (110) such that light (112) emitted from the light source (120) can reflect off the paper tape (110). The light (112) can emit in at least three wavelengths selected from red, green, blue, and ultra-violet wavelengths, and pattern recognition can be used to identify and/or distinguish the nuisance gas from the target gas or from the group of target gases.
