摘要： Systems and methods are provided for a portable gas detector having an indicator that is configured to display an indication, such as a color indication, to a user of the portable gas detector, wherein the indication represents a particular gas sensor configuration setting. The portable gas detector may have one or more gas sensors configured to detect multiple species of gas and a controller configured to control configuration settings of the one or more gas sensors. The indication provided to the user allows for the efficient selection of the correct portable gas detector for each individual task, without requiring a user to rely on potentially inaccurate physical labels or to manually check device settings.

摘要： A system includes a pressure regulator including a housing, an inlet for connection to a pressurized gas comprising oxygen, and at least one energy transfer element. The system further includes a respiration facepiece including at least one seal system to form a sealing engagement with the face of a user to encompass the nose and mouth of the user, thereby creating a volume of sealing engagement between the respiration facepiece and the user, an opening into the volume of sealing engagement of the respiration facepiece in communicative connection with an interface for removable attachment of the pressure regulator to the respiration facepiece, and an inspiration port in fluid connection with the interface and in fluid connection with the volume of sealing engagement. The pressure regulator interface includes at least one cooperating energy transfer element such that energy can be transferred between the at least one energy transfer element and the at least one cooperating energy transfer element to transfer at least one of data or power into the volume of sealing engagement.

摘要： A connection arrangement for use with a wearable body harness includes a first connector having a first body component, a second body component, and an attachment element connected to each other by a rod having a longitudinal axis. The connection arrangement further includes a second connector removably connectable to the first connector. Each of the first body component, the second body component, and the attachment element are independently movable relative to each other about the longitudinal axis of the rod. The first connector and the second connector are removably connectable to each other via a locking and release mechanism between a first, locked configuration, where the first connector and the second connector are connected to each other, and a second, unlocked configuration, where the first connector and the second connector are disconnected from each other.

摘要： A system includes a system housing including an inlet, at least one gas sensor responsive to a first analyte gas other than oxygen within the system housing and in fluid connection with the inlet, and a sensor responsive to oxygen within the system housing and in fluid connection with the inlet. The sensor responsive to oxygen is formed to be chemically separate from the at least one gas sensor responsive to the first analyte gas other than oxygen. The sensor responsive to oxygen is responsive to a change in the concentration of oxygen arising from creation of a driving force in the vicinity of the inlet to provide an indication of a state of a transport path between the inlet of the system and the at least one gas sensor responsive to the first analyte gas other than oxygen.

摘要： 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.
