Abstract: A method of operating a sensor system including at least one sensor for detecting an analyte gas and a control system includes electronically interrogating the sensor to determine the operational status thereof and upon determining that the operational status is non-conforming based upon one or more predetermined thresholds, the control system initiating an automated calibration of the sensor with the analyte gas or a simulant gas.

Abstract: An alignment tool for use in connection with an open path gas detection system, which includes an interface including one or more connectors, includes an optical system having a scope and an attachment system operatively connected to the optical system. The attachment system includes a body including one or more cooperating connectors. The body is rotatable about an axis thereof in a first direction to bring the one or more cooperating connectors into connection with the one or more connectors. The attachment system further includes one or more locking elements which engage the one or more connectors after a predetermined amount of rotation of the body in the first direction to form a state of locked engagement. k release member is in rotatable connection with the body in a second direction, opposite the first direction, to cause the one or more locking elements to disengage from the one or more connectors of the interface so that the body can be rotated in the second direction to remove the attachment system from connection with the interface.

Abstract: A protective helmet has an outer shell, a protection shield movable relative to the outer shell between a deployed position and a stowed position, and a linkage mechanism for connecting the protection shield to the outer shell and permitting movement of the protection shield between the deployed and stowed positions. The linkage mechanism has a first link with a first end connected to the outer shell and a second end connected to the protection shield, a second link having a first end connected to the outer shell and a second end connected to the protection shield, and a biasing member having a first end connected to the first link and a second end connected to the second link. The second end of the biasing member moves between the first and second ends of the second link during movement of the protection shield between the deployed and stowed positions.

Abstract: A bypass knob for a pressure regulator configured for use with a facemask of a breathing apparatus has a first member having a first engagement surface and a second member having a second engagement surface positioned opposite the first engagement surface. At least one slot is formed on the first engagement surface and at least one deflectable beam having a latch is formed on the second engagement surface of the second member. When the first member is rotated in a first direction about the longitudinal axis via a first rotational torque, the latch of the at least one deflectable beam is engaged with the at least one slot to rotate the second member with the first member, and disengaged when the first member is rotated in the first direction via a second rotational torque higher than the first rotational torque.

Abstract: An open path gas detector for detecting the presence of a target gas in the presence of fog or water vapor. A transmitter transmits flashes of optical energy along a path in an area under surveillance, including energy at a sample wavelength region at which the target gas is absorbed, at a reference wavelength region not significantly absorbed by the target gas, and at a synchronization wavelength region different from the first and second wavelengths. A receiver includes a sample channel responsive to the optical energy at the sample wavelength region, a reference channel responsive to optical energy at the reference wavelength region, and a third synchronization channel responsive to the optical energy at the synchronization wavelength region. The receiver detects the target gas and synchronizes operation of the receiver to the transmitter flashes of optical energy using the output of the synchronization channel.

Abstract: A system includes a primary combustible gas sensor and a trigger combustible gas sensor including a first trigger element of low-thermal-mass which includes a first trigger heating element in operative connection with electronic circuitry. The trigger combustible gas sensor also includes a second trigger element of low thermal mass including a second trigger heating element. The second trigger element is also in operative connection with the electronic circuitry. The electronic circuitry further has a first trigger mode of operating in which the first trigger element is heated to a temperature at or above a temperature at which the first trigger element causes combustion of the at least one combustible gas analyte and wherein the second trigger element is operated as a trigger compensating element. The electronic circuitry is configured to operate the trigger combustible gas sensor to detect a value of a response at or above a threshold value. The primary combustible gas sensor is activated from a low-power state upon the threshold value being detected by the trigger combustible gas sensor.
