    摘要： A system includes a count detector, a communication medium; and a processor coupled to the count detector. The processor continuously receives a plurality of pulses from the count detector. A pulse indicates a detection of a radiation unit emitted from a source material or a background. The processor determines a first period of time based on an expected range of speed of a carrier of the source material, and integrates the plurality of pulses over the first period of time, thereby yielding an integrated count associated with a time at a midpoint of the first period of time. The processor creates a continuous time series of count profiles from a plurality of integrated counts that are computed using a plurality of windows within the first period of time, and shifts each window over a second period of time. The second period of time is shorter than the first period of time. The processor estimates a background count from a history of the count profiles, computes an adaptive threshold based on the estimated background count, and detects the source material when consecutives of the integrated counts exceed the adaptive threshold.

    摘要： A particulate matter (PM) sensor includes an embedded self-calibrator. The PM sensor is to be installed in an exhaust corridor of an internal combustion engine. The PM sensor can self-calibrate by imposing a known potential across a protective housing in which the conductive probe is suspended. An image charge that is imposed upon the conductive probe is fed back and correlated to generate an updated calibration for the PM sensor.

    摘要： A system includes a filter, a sensor, a processor, and a memory. The filter can be coupled to an engine exhaust and can operate in an accumulating mode during which particulate matter (PM) from the engine is trapped and also operate in a regenerating mode during which PM in the filter is emitted. The sensor is coupled to a discharge port of the filter and has an output to provide a sensor signal based on a concentration of PM in the filtered exhaust. The processor is coupled to receive the sensor signal and operable to determine at least one of a base level for the sensor signal during the accumulating mode and a regenerate level for the sensor signal during the regenerating mode, and operable to determine a calibration value for the sensor using at least one of the base level and the regenerate level. The memory stores the calibration value.

    摘要： A fluid conveyance apparatus having more than one particulate matter sensing probe situated at two or more locations on the apparatus. Signals from the probes from at least two locations may indicate particulate matter flowing within a fluid through the conveyance apparatus. The times between signals may be indicated the rate of movement of the particulate matter in the conveyance apparatus and also a flow rate and direction of the fluid. The sensing probe signals may be processed into control signals that may go to a flow control mechanism. An example application of the flow control mechanism may be for an exhaust gas recirculation system of an engine.

    摘要： A spectroscopic system having a coded aperture as a gating device. Light of a Raman scattering may enter the system and encounter a mask gate. The mask may have a matrix of micro mirrors some of which pass light on to a diffraction grating when the gate is on. Some of the mirrors will not pass on light thereby resulting in coded light to the grating. If the gate is off, then no light is passed on to the grating. The grating may pass the coded and spectrally spread light on to a detector array. The array signals representing the light on the array may go to a processor so one can obtain information about the target that emanated the Raman scatter when impinged by a light beam.
