  • Patent number: 8726720
    Abstract: A particulate monitoring system includes a conduit in which to a pass a fluid sample from an input port to an output port. The particulate monitoring system receives a fluid sample inputted to the conduit through the input port. The fluid sample can include different sizes of particulate matter. The particulate monitoring system controls a flow of the fluid sample through the conduit to age the particulate matter. Gravitational forces cause a portion of the particulate matter in the fluid sample to fall into a basin as opposed to being exhausted through the output port, which is disposed at a vertically higher level of the conduit than the input port. Thus, the particulate monitoring system outputs a portion of the original particulate matter in the fluid sample (e.g., particulate matter that does not drop into the basin out due to gravity) for analysis.

    Abstract: In order to improve a system for monitoring the working area atmosphere of an operating engine, measuring devices (2) for determining readings for a gas and/or an aerosol in the working area (4) of an operating engine are used as a starting point. Each measuring device comprises a suction means (8) which extracts a gas and/or a mixture of an aerosol from the working area (4) of the operating engine and feeds it to a sensor unit (16, 17, 18). An electronics module for operating the sensor unit (16, 17, 18) is also present. The suction means is designed as a convection pump (8) preferably with a heating device (42) and a cooling device (44).

  • Patent number: 8424365
    Abstract: A method of operating a screening system includes applying an electromagnetic field to a subject in a region at least partially enclosed by electromagnetic shielding, and measuring an output from a sensor. The output is representative of an interaction of the electromagnetic field and the subject. A trace vapor is collected from the subject within the region, and the trace vapor is identified. Based on the measured sensor output and the identified trace vapor, whether a target material is associated with the subject is determined.

  • Patent number: 8294587
    Abstract: A smoke detector has a housing, a smoke sensor in the housing capable of detecting smoke therein, and an alarm connected to the sensor signaling when the smoke sensor detects smoke. A partition subdivides the housing into separate first and second chambers, and the housing is formed with first and second smoke holes allowing air from the exterior into the first and second chambers. The partition has a sensor port provided with a sensor for detecting air flow through the sensor port and a fan port having a fan for drawing air from one of the chambers and forcing it into the other chamber. A controller connected to the fan and to the air-flow sensor operates the fan means to move air from the one chamber through the fan port into the other chamber and generates an output when air flow through the sensor port exceeds a predetermined limit.
