Abstract: A particulate trap has a housing with an inlet and an outlet. The particulate trap also has a plurality of filters disposed within the housing in parallel relation. The particulate trap further has at least one electrode disposed within the housing and configured to impart a charge to particulates entrained within an exhaust flow as the particulates pass near the at least one electrode.

Abstract: A particulate trap has a housing with an inlet and an outlet. The particulate trap also has an electrostatic filtering device disposed within the housing, a filtering element disposed downstream of the electrostatic filtering device, and an unfiltered flow passageway from the electrostatic filtering device around the filtering element.

Abstract: In a method and system for managing concurrent access to multiple resources, resources are assigned to sets in such a way that it is safe to concurrently access any combination of resources in a resource set. For each resource set, a virtual machine is defined and associated with the resource set. An application is assigned to a virtual machine. When an application requests access to a resource not in the application's virtual machine, access control lists are consulted to determine whether the access should be allowed, given the other resources already accessed by the application.

Abstract: A method, identification tag reader and computer program product for communication with an identification tag are disclosed. To communicate with the tag, identification data may be retrieved from an identification tag. A guest identification, compliant with at least a portion of a standard network protocol address, may be assigned to the identification tag. A message addressed to a tag routing address of the tag may be received, and a response to the message may be sent.
