摘要： A sampling point for use with an aspirating particle detection system. The sampling point includes: a body; a plurality of apertures in the body for drawing an air sample from an ambient environment; an outlet for delivering the sampled air, at a predetermined sample flow rate, from the body into a sampling pipe of the network of sampling pipes; and a means for maintaining the predetermined sample flow rate regardless of the presence or absence of ambient flow of air about the body. A particle detection system, and air sampling system are also described.

摘要： An apparatus and method controls an environmental control system to maintain a differential pressure between a room and one or more adjacent areas by (1) determining a differential pressure error based on the differential pressure and a differential pressure set point using a proportional-integral-derivative (PID) controller; (2) increasing an air change per hour set point whenever one or more first parameters are satisfied; (3) decreasing the air change per hour set point whenever one or more second parameters are satisfied; and (4) sending one or more control signals to the environmental control system that maintain the differential pressure between the room and the one or more adjacent areas by adjusting: (a) the leading airflow to be approximately equal to the air flow change set point multiplied by a volume of the room divided by 60, and (b) the tracking airflow to maintain a volume differential set point.

摘要： Fuel cell gas sensors using an aperture in a fuel cell gas sensor that allows for determination of a gas proportion in a sample that includes more gas than could otherwise be safely sampled. The aperture is adjustable between an open and a closed state. The amount of the gas of interest exposed to the fuel cell may be adjusted by adjusting the amount of time that the aperture is in the open state. Alternatively, the amount of the gas of interest exposed to the fuel cell may be adjusted by adjusting the size of the aperture.

摘要： A system for tracking one or more subjects for collecting airborne contaminants. The system includes one or more subjects configured to collect air contaminants. Each of the one or more subjects includes an identification tag encoded with identification information identifying the each subject. The system further includes an identification reader configured to decode the identification information encoded within the identification tag of a scanned one of the one or more identification tags. A computer receives and stores the decoded identification information in a record in a database. The computer may also receive and stored an identification code for a user who scanned the scanned identification tag in the record in the database. Additional records in the database are created each time the identification tag of one of the one or more subjects is scanned. The one or more subjects are thereby tracked as they collect airborne contaminants and are incubated.

摘要： A method for determining correct performance of a sampling pipe in an aspirated particle and/or gas sampling system. The method includes causing a change in airflow n a sampling pipe of the aspirated particle and/or gas sampling system that induces a change in at least one airflow property within the sampling pipe, and detecting an effect of the change in said airflow property. Also disclosed is a method for determining correct performance of an aspirated particle gas sampling system. The method includes determining correct performance of a sampling pipe in the aspirated particle and/or gas sampling and determining correct performance of a detector in the aspirated particle and/or gas sampling system, wherein a test fluid is introduced to the aspirated particle and/or gas sampling system at or near the detector.

摘要： A system and method for sampling air in a controlled environment that includes two or more air sampling devices at different locations within the controlled environment. A controller is provided at a location outside of the controlled environment and in separate air flow communication with each of the two or more air sampling devices via separate first vacuum tubes, the controller having a manifold configured to separately control a rate of air flow from the two or more air sampling devices to the controller via each of the separate first vacuum tubes and to selectively direct the air flow from each of the separate first vacuum tubes to one or more second vacuum tubes. A vacuum source is provided at a location outside the controlled environment and in air flow communication with the controller via the one or more second vacuum tubes, the vacuum source providing suction and being controlled by the controller to generate the air flow through each of the first vacuum tubes. And, a flow switch for each of the two or more air sampling devices is provided at a location between a corresponding air sampling device and the vacuum source, each of the flow switches being configured to separately measure and control the rate of air flow through a corresponding first vacuum tube. An alarm is automatically activated at a location inside the controlled environment by one or more of the flow switches when the rate of air flow measured at one or more of the flow switches deviates from a desired value by a predetermined amount.
