Abstract: Gas analyzing techniques for monitoring the amount of oxygen in the exhaust of motor vehicles. An oxygen sensor produces a sensor signal having a sensor value proportional to the partial pressure of the oxygen produced by the motor vehicle. Processing circuitry generates a resulting signal proportional to the sum of the sensor value, another value proportional to the first derivative of the sensor value and a third value proportional to the second derivative of the sensor value. The resulting signal can be used to predict the final sensor value at a point in time earlier than would be otherwise possible.

Abstract: A CHEMICAL PROCESS IN WHICH UNREACTED FEED CONSTITUENTS ARE RECYCLED, SUCH AS AMMONIA SYNTHESIS, IS CONTROLLED BY ESTABLISHING A FIRST SIGNAL REPRESENTATIVE OF THE RATIO OF TWO CONSTITUENTS FED TO A REACTOR. A SECOND SIGNAL IS ESTABLISHED WHICH IS REPRESENTATIVE OF THE DERIVATIVE OF THE FIRST SIGNAL. IN RESPONSE TO A COMBINATION OF THE FIRST AND SECOND SIGNALS, THE RATIO OF FEED CONSTITUENTS TO THE PROCESS IS CONTROLLED.

Abstract: A gas detection device for detection of one or more gas analytes in an environment includes a housing including an inlet via which gas to be sampled from the environment enters the housing, a control system within the housing comprising a processor system and a memory system in communicative connection with the processor system, and one or more gas sensors within the housing in fluid connection with the inlet and in communicative connection with the control system. Each of the one or more gas sensors is independently responsive to one of the one or more gas analytes. The control system is configured to control flow rate of gas from the environment through an accessory device assembly including one or more accessory devices in fluid connection with the inlet on the basis of data for the accessory device assembly in fluid connection with the inlet.

Abstract: A gas analysis device for analyzing a compound gas and H2O gas produced in a main reaction in which an aqueous solution including a compound and water is vaporized, includes a first concentration calculating unit that calculates a concentration of the compound gas, a second concentration calculating unit that calculates a concentration of the H2O gas, an analysis unit that compares a first actual concentration which is the concentration of the compound gas calculated by the first concentration calculating unit with a first ideal concentration which is the concentration of the compound gas in case that the main reaction proceeds ideally, and that compares a second actual concentration which is the concentration of the H2O gas calculated by the second concentration calculating unit with a second ideal concentration which is the concentration of the H2O gas in case that the main reaction proceeds ideally and an output unit.

Abstract: According to one embodiment, a data processing device includes an acquisitor and a processor. The acquisitor can acquire a first concentration signal obtained from a first concentration sensor configured to detect a first concentration of a first target substance included in a first output gas and a first flow rate signal obtained from a first flow rate sensor configured to detect a first flow rate of the first output gas. The processor can derive a first concentration value corresponding to the first concentration based on the first concentration signal. The processor can derive a first corrected conversion coefficient obtained by correcting a first conversion coefficient regarding a relationship between the first flow rate signal and the first flow rate based on the first concentration value. The processor can derive a first flow rate value corresponding to the first flow rate based on the first flow rate signal.

Abstract: Embodiments relate generally to a gas detector test fixture (102) that recycles test gas, which can then be reused. A portable gas detector test fixture (102), comprises a test chamber (104), a processor (134), a docking connector (132) communicatively coupled to the processor (134), an output device (138) communicatively coupled to the processor (134), a memory (136) communicatively coupled to the processor (134), and an application (137) stored in the memory (136) that, when executed by the processor (134), is configured to conduct a bump test on a portable gas detector (106) plugged into the docking connector (132) and to output the bump test result to the output device (138). The test fixture (102) further comprises an inflow line (124) configured to connect to a test gas supply line (120) of a test gas container (118), where the inflow line (124) is coupled to the test chamber (104), and an outflow line (130) configured to connect to a test gas return line (126) of the test gas container (118), where the outflow line (130) is coupled to the test chamber (104).

Abstract: A method for displaying gas concentration values on a graphical display of a leak detector comprises detecting a presence of a gas using a gas sensor. A signal is generated by the gas sensor and transmitted from the gas sensor to a processor. The received signal is processed to determine a gas concentration value and a corresponding time stamp. The gas concentration values and corresponding time stamps are displayed graphically as they are determined and newly determined gas concentration values and corresponding time stamps are displayed in relation to previously determined gas concentration values and time stamps in streaming manner.

Abstract: A gas sensor array comprises a plurality of metal decorated metal oxide film based on three-dimensional nanostructured templates, each including a porous anodized aluminum oxide (AAO) template and a plurality of metal decorated metal oxide films. The porous AAO substrate has a top surface with top gold electrodes, a bottom surface with bottom gold electrodes and a plurality of pores. Each pore has an interior wall and two openings located on the top surface and the bottom surface respectively for allowing air to enter into the pore. Each metal-decorated metal oxide film comprises a metal oxide film and metal decoration particles. The metal oxide film has an internal surface attaching on a respective interior wall and an external surf-ace being decorated with the metal particles. Each decoration metal is different to provide different sensitivities in response to an environmental gas.
