摘要： A sensor assembly to measure particulate matter is described. The sensor assembly includes a voltage source, a sensor electrode, a grounded assembly, an integration capacitor, and a current meter. The sensor electrode is coupled to the voltage source to receive a voltage. The sensor electrode is disposed within a directed and controlled exhaust flow within the sensor assembly to facilitate particle agglomeration into particulate matter structures at a surface of the sensor electrode. The grounded assembly is coupled to a ground reference and disposed at a distance from the sensor electrode. The integration capacitor is coupled to a negative side of the voltage source. The integration capacitor is configured to integrate in time current pulses from charge transfers from the sensor electrode of the particulate matter structures.

摘要： A flow head (200) for a gas sensor (100) having a sensing element (108) is provided. The flow head includes a body (201) at least partially defining a cavity (210) in communication with the sensing element. The body includes an inlet port (204) located within an annular surface (218) of the body and an outlet port (206) located within the annular surface of the body. The body also includes an inlet passage (208) offset from and parallel to the cavity, wherein the inlet passage configures the inlet port and the cavity to be in fluid communication with one another. The body further includes an outlet passage (209) offset from and parallel to the cavity, wherein the outlet passage configures the outlet port and the cavity to be in fluid communication with one another.

摘要： A device for signal processing. The device includes a signal generator, a signal detector, and a processor. The signal generator generates an original waveform. The signal detector detects an affected waveform. The processor is coupled to the signal detector. The processor receives the affected waveform from the signal detector. The processor also compares at least one portion of the affected waveform with the original waveform. The processor also determines a difference between the affected waveform and the original waveform. The processor also determines a value corresponding to a unique portion of the determined difference between the original and affected waveforms. The processor also outputs the determined value.
