Abstract: A statistical condition detection and resolution management method includes sampling data and performing statistical analysis on the sampled data, the sampled data representing events detected by an event profiling engine. The method also includes generating, a profile from results of the statistical analysis, the profile indicating a normative value of an attribute identified in the sampled data, and any outliers identified in the sampled data. Upon discovering an outlier, the method includes creating, via a rule engine in communication with the event profiling engine, a rule that defines an action to be taken for a condition identified as a result of the statistical analysis, and monitoring, via an event processing engine in communication with the rule engine, real-time operational data corresponding to attributes of the profile. When in response to the monitoring the condition is met, the method includes implementing the action identified in the rule.

Abstract: A filter assembly attachable to the discharge opening of a contaminated air source includes a filter having an outer periphery; a flexible conduit having a continuous side wall, an outer end attachable to the discharge opening, and an inner end attachable about the periphery of the filter; and a flexible side protrusion extending from the conduit sidewall, the protrusion having an inner end in communication with the interior of the conduit and a closed outer end. The filter can be mounted within an enclosure with an inlet opening and a discharge outlet, the conduit extending through the inlet opening and the filter being located within the enclosure.

Abstract: A biohazard safety enclosure or workstation particularly adapted for enclosing automated instrumentation includes a chamber defined by front, back, top, bottom, and opposed end walls; a HEPA filter across an air inlet opening into the chamber, and an airflow means to direct air horizontally through at least part of the chamber between the end walls. Preferably, the workstation has a second HEPA filter across an air outlet opening in the work chamber, with the airflow means including a conduit extending from the air outlet opening to the air inlet opening. A fan draws air through the conduit. All of the air can be exhausted from the workstation, or a part of the filtered air can be exhausted from the workstation and replenished through a make-up air inlet into the chamber.

Abstract: A biological safety cabinet includes a work chamber having a contaminated air discharge opening, a fan enclosure above the work chamber, a conduit extending from the chamber air outlet to the top of the fan enclosure, a first HEPA filter in the top of the fan enclosure, a second HEPA filter between the fan enclosure and the work chamber, and a fan within the fan enclosure to convey air through the conduit from and the first HEPA filter into the fan enclosure, and to discharge air under positive pressure from the fan enclosure through the exhaust port and through the second HEPA filter into the work chamber. Due to the construction of the cabinet, the fan can be repaired or replaced without the need to observe biohazard procedures.
