摘要： A system for detecting an analyte gas including a system housing having an inlet system, an electrochemical gas sensor within the housing and in fluid connection with the inlet system, the electrochemical sensor including a working electrode responsive to the analyte gas, and a control system in electrical connection with the working electrode. The control system is operative to bias the working electrode at a first potential at which the electrochemical gas sensor is responsive to the analyte gas and operative to bias the working electrode at a second potential, different from the first potential, at which the electrochemical gas sensor is sensitive to a driving force created in the vicinity of the inlet system to test at least one transport path of the system.

摘要： A method of testing a system, which has at least one electrochemical sensor for detecting an analyte gas within a housing of the system, and the housing has an inlet, includes exhaling in the vicinity of the inlet of the housing of the system and measuring a response to exhaled breath to test one or more transport paths of the system. Measuring the response to exhaled breath may, for example, include measuring the response of a sensor within the housing of the system that is responsive to the presence of exhaled breath. The sensor responsive to the presence of exhaled breath may, for example, include an electrochemically active electrode responsive to a gas within exhaled breath. The electrochemically active electrode may, for example, be responsive to carbon dioxide or to oxygen.

摘要： A combustible gas sensor includes a first sensing element, which includes a catalyst and a heating element in operative connection with the catalyst to heat the catalyst above a temperature to combust gas analytes of interest, and electronic circuitry in operative connection with the heating element of the first sensing element to periodically cycle the first sensing element between a temperature above the temperature to combust the analytes of interest and a temperature at which the catalyst is substantially inactive to catalyze oxidative combustion of the analytes of interest. The electronic circuitry is adapted to determine a species of at least one of the gas analytes of interest from a first output of the combustible gas sensor during an ON time within a cycle duration. The electronic circuitry is further adapted to determine a concentration of the species of gas from a second output of the combustible gas sensor.

摘要： A system includes a carrier system adapted to be worn by a user and to support at least one of a plurality of differently sized tanks of breathing gas, a bracket connector attached to the carrier system, and a plurality of brackets. The carrier system may, for example, be part of a breathing apparatus such as a self-contained breathing apparatus. Each of the plurality of brackets has a different configuration. Each of the plurality of brackets is attachable to an associated one of the plurality of differently sized tanks and to the bracket connector. For each one of the plurality of brackets, an assembly that includes the one of the plurality of brackets and the associated one of the plurality of differently sized tanks, when attached to the bracket connector, positions the associated one of the plurality of differently sized tanks in a predetermined manner relative to the carrier system.

摘要： A combustible gas sensor includes at least a first sensing element comprising a first conductive element having, for example, an average diameter less than 20 μm in electrical connection with electronic circuitry. The combustible gas sensor further includes a first support element having a first anchored end, a second anchored end and an extending intermediate section between the first anchored end and the second anchored end, the extending intermediate section providing support for the first conductive element. Another combustible gas sensor includes a first sensing element and a second sensing element. The first sensing element includes a first catalyst support member having a volume less than a sphere having a diameter of 500 μm. The second sensing element includes a second catalyst support member having a volume less than a sphere having a diameter of 500 μm. The combustible gas sensor further includes electronic circuitry that is adapted to cycle between a first mode in which the first sensing element is operated in a higher power mode and the second sensing element is operated in a lower power mode and a second mode in which the second sensing element is operated in a higher power mode and the first sensing element is operated in a lower power mode.

摘要： An SCBA backpack for air cylinders includes a chassis with a cradle receiving arrangement and a tank cradle for holding at least one air cylinder, wherein the tank cradle is removably secured to the chassis. Such an arrangement permits a variety of different tank cradles that may secure one or more cylinders but that are still compatible with a common backpack chassis.
