Abstract: Messages are targeted to travelers based on travel itineraries. Targeting may also be based on real-time travel status information. The targeted messages communicate their purpose and priority to respective travelers within the context of the travel itineraries. A disclosed method includes accessing a travel itinerary database including a plurality of travel itineraries. Each travel itinerary is associated with a traveler and defines itinerary segments of a corresponding travel schedule. A message is associated with a set of targeting rules used to identify a subset of itineraries in the travel itinerary database. The targeting rules may be used with real-time travel status information to identify the subset of itineraries.

Abstract: The software system of the present invention is a distributed object oriented software system that it is customizable and flexible enough to implement a wide variety of different “business logics” without the need to rewrite the basic components of the software system because it provides scripting capability in a distributed object-oriented software system. The present invention includes a rules-based scripting language that can be interpreted by a Rules Engine that is part of the base class of component for the software system. In accordance with the present invention each individual component of the software system may have one or more predetermined rule sets defined for it. Each predetermined rule set allows customization of the behavior of the associated component of the software system.

Abstract: A filter package having a long shelf-life and containing substantially no contaminants comprises a filter cartridge, a flexible bag surrounding the filter cartridge having walls comprising a polymeric material impervious to microorganisms and liquid water, a venting mechanism formed in a wall of the flexible bag, and sanitized water sealed inside the flexible bag and immersing substantially 100% of a volume of the filter cartridge. The filter cartridge includes a porous filter medium having a plurality of pores through which a fluid can pass between an upstream side and a downstream side of the filter cartridge and the sanitized water substantially permeates the pores of the filter medium. The venting mechanism includes a vent filter preventing the passage of microorganisms into the flexible bag.

Abstract: A method of forming a filter package includes disposing a filter and a liquid in a container with the filter immersed in the liquid and sanitizing the liquid and the filter while in the container. After sanitizing, the container may be hermetically sealed to enclose the sanitized liquid and filter. The container may be vented during sanitizing to allow vapor of the liquid to exit from the container and prevent pressure from building up in the container. The container may be either rigid or flexible.

Abstract: A filter includes a cylindrical pleated filter element having a longitudinal axis, an inner and outer periphery, first and second end surfaces, and a plurality of longitudinal pleats. First and second end elements are sealingly arranged with the first and second end surfaces, wherein at least one of the end elements is an open end element. The filter element is a pleated composite that includes a filter medium, an upstream drainage medium and a downstream drainage medium. Each pleat includes a crown, a root, and a pair of legs. The legs of each pleat are joined to one another at the crown of the pleat and are joined to the legs of adjacent pleats at the root of the pleat. Each pleat leg abuts an adjacent pleat leg along the inner periphery of the filter element and the pleats extend from the inner periphery in a curved, an arcuate, an angled, or a straight nonradial direction to the outer periphery.

Abstract: An apparatus for use in processing fluids includes a tubular porous element, a housing disposed about the porous element, and grooves and passages disposed between the housing and the porous element.

Abstract: A filter includes a cylindrical filter element having a longitudinal axis, first and second end surfaces, and a plurality of longitudinal pleats. Each of the pleats has a pair of legs with first and second surfaces. The pleats are in a laid-over state in which the first surface of each leg is in intimate contact with the first surface of an adjoining leg and the second surface of each leg is in intimate contact with the second surface of an adjoining leg over substantially the entire height of each leg and over a continuous region extending for at least approximately 50% of the axial length of the filter element. An impervious end cap is connected to the first end surface of the filter element.

Abstract: A filter assembly for decreasing fluid hold-up waste and providing uniform flow while maintaining desired flow rates and pressures comprises a housing, a filter element including first and second end caps and a filter fastened therebetween, and a sleeve. The sleeve is positioned around the filter and may be joined to the first and second end caps, thereby forming the cage as a single integral unit which is positioned within the housing.
