Abstract: An air delivery conduit includes first and second conduit portions that cooperate to form the conduit, each conduit portion including an inner layer of a film laminate that forms an interior surface of the conduit and an outer layer of a textile that forms an exterior surface of the conduit.

Abstract: The disclosed bushing assembly has a housing with a central bore for receiving a bushing sleeve that is dimensioned to fit a predetermined sway bar. The housing and sleeve have various combinations of mating projections and recesses that secure the sleeve in the housing. A bushing kit has a plurality of sleeves that are dimensioned to fit different predetermined sway bars and an appropriate sleeve can be selected at the time of installation. The housing and the sleeve are flexible.

Abstract: The present application relates to a system and method for sorting mailpieces prior to their delivery to the postal authority. The system and method allow for the running of different first pass sort schemes on multiple sorters in a sorting facility without stopping operations for no-count mode, without losing mailpiece tracking, or waiting for all first pass sorting to complete before re-running the mail that was not sorted to the finest depth of sorting. With the present application, mailpieces that can be run a second time can be run concurrently during first pass without the high risk no-count mode or loss of data integrity.

Abstract: A solution to the problem of maintaining application integrity when device drivers fail. This solution employs a new mechanism, the shadow driver, which is an operating system (OS) kernel agent that monitors communication between the OS kernel and the device driver it “shadows.” When a device driver error occurs, the shadow driver acts in place of the failed device driver, intercepting and responding to calls from the OS kernel and the device driver during cleanup, unloading, reloading, and re-initialization of the failed device driver. Applications and the OS kernel are thus isolated from the failure. An initial embodiment was developed for use with the Linux™ OS and was tested with a dozen device drivers. Results demonstrate that shadow drivers successfully mask device driver failures from applications, impose minimal performance overhead, require no changes to existing applications and device drivers, and can be implemented with relatively little code.

Abstract: A method of controlling access to network services enables an authorized proxy client to access a service on behalf of a user. To permit the client to function as a proxy, the user registers proxy authorization information with a trusted security server. The proxy authorization information identifies the proxy client and specifies the extent of proxy authority granted to the proxy client. When the proxy client wants to access a target service on behalf of the user, it sends a proxy request to the trusted security server. The trusted security server checks the proxy authorization information of the user to verify whether the request is within the proxy authority granted to the proxy client. If so, the trusted security server returns to the proxy client a data structure containing information recognizable by the target service to authenticate the proxy client for accessing the target service on behalf of the user.

Abstract: Mail processing methods and techniques for sorting and commingling mail from various mail sources including the tracking of the mail pieces through processing. Such tracking entails uniquely identifying each mail piece, received in batches from the mail sources, and recording the unique identification of each mail piece. The received mail is sorted and commingled in a first pass, to form first collections, and each first collection is loaded into a uniquely identified mail container. For each respective mail piece, the tracking entails recording an association of the unique identification of one of the mail containers into which it is likely the respective mail piece is sorted on the first pass. After processing is complete, postal and client reports can be adjusted based on actual first pass counts.

Abstract: This application concerns the separation of fine granular mixtures that may occur when the grains are suitably vibrated within fluid. In particular, the present invention provides a method of separating a particulate mixture comprising different particle types, comprising subjecting a supported particle bed comprising a fluid and said particulate mixture to a vibration thereby to effect separation of the particulate mixture into strata each of which is preferentially rich in substantially one particle type. Apparatus for effecting the above method also provided.
