    Abstract: A particulate matter detection sensor has an element part for detecting an amount of PM contained in exhaust gas emitted from an internal combustion engine. A deposition part and at least a pair of detection electrodes are formed on an end surface of the element part. Some of particles of PM is deposited on the deposition part. The pair of detection electrodes are arranged on the deposition part. The particulate matter detection sensor changes its output electrical signal according to variation of electrical properties between the pair of the detection electrodes due to deposition of PM on the deposition part. A concave collection part is formed on the deposition part. The concave collection part has a concaved shape when viewed from the edge surface of the element part.

    Abstract: An air quality test unit for attachment to a vent of a HVAC system with air flow there through. The air quality test unit contains at least two substrate panels arranged in a v-shape form wherein at least one panel includes a sticky surface or a collection container. The air quality test unit is attachable to the vent by one or more clips. The sticky surfaces or collection container of the substrate panels capture airborne substances and contaminants emanating from the air flow of the HVAC system vent. A culture growth medium may be disposed in the collection container or on the sticky surface. The air quality test unit kit provides a user with an air quality test unit and process for shipping the unit to the laboratory for analysis.

    Abstract: Disclosed is a bacterial counting method, comprising the following steps, S1: preparing a polyaniline/bacterial composite film on the surface of a glassy carbon electrode by electric polymerization; S2: drawing the standard curve of the polyaniline/bacterial composite film modified electrode; and S3: determining the bacterial concentration of the bacteria solution sample to be tested according to the standard curve obtained in step S2. The method does not require the cultivation of the bacteria in the implementation process, such that same takes a short time and is easy to operate; the method uses aniline as the main reagent, and the consumption of the solution to be tested is small, such that the testing cost is low and the equipment is simple; the method has the advantages of a good repeatability and a wide detection linear range; and the method is an easy to operate, short time-consuming, and low cost bacterial counting method. The method is a bacterial counting method based on the polyaniline/bacterial composite film, and can achieve rapid and accurate detection of the bacterial thallus concentration.

    Abstract: A system includes an exhaust system fluidly configured to define an exhaust stream. A sensor is arranged in the exhaust system and is configured to be exposed to the exhaust stream and accumulate particulate matter on the sensor. The sensor provides a signal that varies based upon an amount of particulate matter on the sensor. A control system is in communication with the sensor. The control system includes a controller configured to calculate a differential of a conductance signal related to the signal, compare consecutive differentials to identify an erroneous differential in an abnormal signal based upon an anomaly relating to the accumulation of the particulate matter, and reconstruct the abnormal signal by correcting the erroneous differential to produce a corrected, decimated conductance signal. The control system is configured to determine a total accumulated particulate matter adjusted for the anomaly.
