Abstract: An apparatus and method for trapping particles disposed in a fluid. The apparatus may comprise one or more cavities disposed axially along a length of a tubular housing, one or more connecting components disposed at opposing ends of the housing, and may optionally comprise a check valve system. Alternate embodiments are provided for forming each of the one or more cavities, which may comprise a combination of a cavity frame and cavity surface. The method may comprise flowing a fluid into a first end of a particle trap apparatus at a rate of fluid flow, directing the fluid flow at least partially through one or more cavity sub-assemblies disposed in the particle trap apparatus, collecting the particulate matter in one or more of the cavity sub-assemblies when the rate of fluid flow may slow or become suspended, and clearing collected particles from the one or more cavity sub-assemblies upon restoration of fluid flow in a primary direction of travel.

Abstract: A method of providing incentives to bidders on an auction item using a database and a system, the method including creating the consumer profile for at least one consumer, choosing at least one of the unsold items from the inventory based on the consumer information in the consumer profile, generating the incentive for the chosen unsold item based on the consumer file, the selection of consumer information of the incentive being substantially similar to the consumer information in the consumer profile, and offering the chosen unsold item and the incentive to the at least one consumer to induce purchasing of the chosen unsold item.
