摘要： An acoustic wave sensor system for monitoring the etch rate or etch ability of a selective material has an acoustic wave sensing device having a piezoelectric substrate and at least one electrode coupled to the substrate for generating a propagating acoustic wave and for detecting changes in frequency or other propagation characteristics of the acoustic wave. A selective material is disposed on the substrate. Changes in propagation characteristics of the wave caused by etching of the selective material by an etchant can be analyzed to evaluate the etching rate or etch ability of the selective material. The sensing system can have a wireless sensing device which device is mountable in an oil filter system for monitoring the corrosion of the engine. The sensing device can be configured as BAW, SH-SAW, SH-APM, FPM devices or other acoustic wave devices.

摘要： A method and system for detecting oil quality. The quality of engine oil can be determined utilizing an acoustic wave sensor to obtain viscosity and corrosivity data associated with the engine oil. The acoustic wave sensor is coated with a material that selectively reacts to at least one type of an acid in order to provide data indicative of the presence of the acids in the engine oil. The etch rate or the corrosivity of the engine oil can be determined based on the frequency data obtained as a result of the frequency measurement utilizing the acoustic wave sensor. The viscosity of the engine oil can additionally be obtained based on a measurement of phase and amplitude obtained from the data utilizing the acoustic wave sensor. The etch rate and the viscosity measurement provide data indicative of the quality of the engine oil.

摘要： A catalyst system that may regenerate while removing pollutants from an exhaust gas of an engine. The system may have a converter with multiple segments of chambers. At least one of the chambers may be regenerated while the remaining chambers are removing pollutants from the exhaust. The chambers may be rotated in turn for one-at-a-time regeneration. More than one chamber may be regenerated at a time to remove collected pollutants. The system may have plumbing and valves, and possibly mechanical movement of the chambers, within the system to effect the changing of a chamber for regeneration. The chambers connected to the exhaust may be in series or parallel. A particulate matter filter may be connected to the system, and it also may be regenerated to remove collected matter.

摘要： A method includes acquiring a chemical sample and modulating the chemical sample at a frequency greater than a drift frequency of a sensor. The method also includes determining at least one of a presence and a concentration of the analyte within the modulated chemical sample using the sensor. Modulating the chemical sample could include alternately absorbing at least some of the analyte into a sorbent material and releasing at least some of the analyte from the sorbent material. Modulating the chemical sample could also include heating the sorbent material, absorbing part of the analyte into the sorbent material, and passing a remaining portion of the analyte into the sensor. Modulating the chemical sample could further include stopping the heating of the sorbent material, releasing the part of the analyte from the sorbent material, and passing the sample with the released part of the analyte into the sensor.
