20130000280 | GAS MONITORING METHOD IMPLEMENTING SOOT CONCENTRATION DETECTION - A method for detecting soot in a gas is disclosed. The method may include applying a voltage pulse to electrodes exposed to the gas, wherein the voltage pulse has a higher voltage amplitude than a breakdown voltage of the gas. The method may also include detecting breakdown of the gas, and determining a time to breakdown of the gas since application of the voltage pulse. The method may additionally include determining a concentration of particulate matter entrained in the gas based on the time to breakdown. | 01-03-2013 |
20130000377 | METHOD OF CONSTITUENT IDENTIFICATION AND CONCENTRATION DETECTION - A method for monitoring a gas is disclosed. This method may include applying a voltage pulse to electrodes exposed to the gas, and determining an actual current between electrodes during application of the voltage pulse. The method may further include determining a concentration of a constituent in the gas based on the actual current and an expected identity of the constituent. | 01-03-2013 |
20130000386 | SYSTEM IMPLEMENTING CONSTITUENT IDENTIFICATION AND CONCENTRATION DETECTION - A gas monitoring system is disclosed. The gas monitoring system may have a first electrode, a second electrode spaced apart from the first electrode to receive a gas between the first and second electrodes, and a pulse generator configured to apply a voltage pulse, tuned to a particular constituent of the gas, to the first and second electrodes and create a non-thermal plasma between the first and second electrodes. The gas monitoring system may also have a detection controller in communication with the pulse generator. The detection controller may be configured to determine an actual current between the first and second electrodes during application of the voltage pulse, and to determine a concentration of the constituent based on the actual current and an expected identity of the constituent. | 01-03-2013 |
20130000412 | GAS MONITORING SYSTEM IMPLEMENTING PRESSURE DETECTION - A gas monitoring system is disclosed. The gas monitoring system may have a first electrode in fluid communication with a first gas and a second gas, and a second electrode spaced apart from the first electrode to contain the second gas between the first and second electrodes. The gas monitoring system may also have a pulse generator configured to apply a series of voltage pulses to the first and second electrodes and create a plasma in the second gas. Each voltage pulse in the series of voltage pulses may have an incrementally higher voltage amplitude than a preceding voltage pulse in the series of voltage pulses. The gas monitoring system may further have a detection controller in communication with the pulse generator. The detection controller may be configured to detect breakdown of the second gas during application of one of the series of voltage pulses, and based on a voltage amplitude of the one of the series of voltage pulses, determine a parameter o | 01-03-2013 |
