The devices, films and methods can include graded layers and a vibration detecting unit. The vibration detecting unit can be a convex or an inverse mesa vibration detecting unit.03-17-2016
20160084136SYSTEM AND METHOD FOR CREATING CATALYST OBD LIMIT PARTS FOR EXHAUST AFTERTREATMENT APPLICATIONS - Catalyst diagnostic limit parts and methods for making catalyst diagnostic limit parts are disclosed. An exemplary catalyst diagnostic limit part includes a substrate and a washcoat coating the substrate. The washcoat includes an active catalyst and an inactive catalyst at a predetermined ratio of active catalyst to inactive catalyst so as to control the performance of the catalyst diagnostic limit part.03-24-2016
20160109420FAILURE DETERMINATION DEVICE FOR EMISSION CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE - When individually controlling a plurality of supply valves is not available, an object of the invention is to determine which of the plurality of supply valves is abnormal with high accuracy, while suppressing a cost increase. A first supply valve, a first selective reduction NOx catalyst, a second supply valve, a second selective reduction NOx catalyst and a NOx sensor are sequentially provided in an exhaust conduit. With a view to identifying which of abnormality of the first supply valve and abnormality of the second supply valve, an instruction is given to the first supply valve and the second supply valve to increase a supply amount of a reducing agent. This identification is based on a NOx concentration detected by the NOx sensor after elapse of a first specified time duration since an instruction time point that is a time point when this instruction is given.04-21-2016
20160161401CAPILLARY ABSORPTION SPECTROMETER AND PROCESS FOR ISOTOPIC ANALYSIS OF SMALL SAMPLES - A capillary absorption spectrometer and process are described that provide highly sensitive and accurate stable absorption measurements of analytes in a sample gas that may include isotopologues of carbon and oxygen obtained from gas and biological samples. It further provides isotopic images of microbial communities that allow tracking of nutrients at the single cell level. It further targets naturally occurring variations in carbon and oxygen isotopes that avoids need for expensive isotopically labeled mixtures which allows study of samples taken from the field without modification. The process also permits sampling in vivo permitting real-time ambient studies of microbial communities.06-09-2016
20160189948DEVICE FOR ANALYZING A SAMPLE GAS COMPRISING AN ION SOURCE - A device for analyzing a sample gas comprises an ion source for generating primary ions, a reaction chamber to which the primary ions produced in the ion source and the sample gas to be analyzed can be supplied in order to form product ions by chemical ionization of components in the sample gas, and an analyzer/detector unit for determining different types of ions. A reaction space in the reaction chamber, within which the primary ions supplied to the reaction chamber and the product ions produced are guided and which extends between a first end facing the ion source and a second end facing the analyzer/detector unit, is surrounded by at least two electrodes which are in the form of helices which wind round a common axis with identical pitches and are offset with respect to one another in the direction of the axis. An AC voltage is applied to each of the electrodes.06-30-2016
