Abstract: A method of detecting at least a blockage status in a porous member separating a measurement chamber of a device including a gas sensor positioned within the measurement chamber which is responsive to an analyte in an ambient environment to be sampled, includes emitting pressure waves from a pressure wave source which travel within the measurement chamber, measuring a first response via a first sensor responsive to pressure waves positioned at a first position within the measurement chamber, measuring a second response via a second sensor at a second position, different from the first position, and in fluid connection with the pressure wave source, determining the blockage status of the porous member based upon a functional relation of the first response and the second response.

Abstract: Systems and methods are provided for an open path gas detection system having a receiver with an optical sensor configured to continuously capture optical image data. The field of view of the optical sensor can include the path of a beam of focused light received by a light sensor of the receiver. The receiver can be configured to receive and temporarily store the optical image data in a memory buffer, and then transfer the optical image data to a persistent memory area upon receipt of a transfer command. A transfer command may be provided in various situations, such as when requested by a receiver, when a predefined object of interest is identified in the optical image data, or when a blockage occurs and light sensor is no longer receiving the beam of focused light.

CPC classification number: G01N33/0062 , G01N33/0073
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.
