An apparatus which extrudes flowable material from a liquifier includes a system for loading filament supplied in a cassette. The cassette is loaded into a loading bay of the apparatus. A strand of filament from the cassette is engaged and advanced along a path to the liquifier using a drive wheel or roller pair. A conduit having an entrance in the loading bay guides the filament as it is advanced. The filament loading system of the present invention provides a convenient manner of loading and unloading filament in a three-dimensional modeling machine, and can be implemented in a manner that protects the filament from environmental moisture.

An improved crimping mechanism well-suited for use with stented prosthetic heart valves. The crimping mechanism includes a plurality of jaws configured for linear non-rotational movement toward a central axis. A rotational plate is formed with a plurality of spiral grooves or tracks for engaging the jaws. Rotational movement of the spiral tracks produces linear movement of the jaws. Nesting of the inner ends of the jaws permits each to be acted on along different radial lines while their inner faces move together evenly to reduce the crimping aperture in a smooth fashion. The crimping mechanism is particularly well-suited for use with stented prosthetic heart valves, such as a prosthetic aortic valve, though it can also be applied to other stented heart valves, venous valves, and even stent grafts which tend to be fairly large.

It is an object of the invention to improve the production efficiency in sealing a thin film integrated circuit and to prevent the damage and break. Further, it is another object of the invention to prevent a thin film integrated circuit from being damaged in shipment and to make it easier to handle the thin film integrated circuit. The invention provides a laminating system in which rollers are used for supplying a substrate for sealing, receiving IC chips, separating, and sealing. The separation, sealing, and reception of a plurality of thin film integrated circuits can be carried out continuously by rotating the rollers; thus, the production efficiency can be extremely improved. Further, the thin film integrated circuits can be easily sealed since a pair of rollers opposite to each other is used.

System and method for performing restores from backups while applications are active and accessing the data being restored. A map correlating destination locations on primary storage to source locations on backup storage for files to be restored may be generated. A restore of the files from the backup storage to the primary storage may be started. During the restore, one or more blocks of data of a file needed by an application may be determined. The map may be accessed to determine if the blocks have been restored. If the blocks have not been restored, the blocks may be restored from the backup storage to the primary storage. The restored blocks of data are accessible by the application while the restore is in progress. The map may be updated to indicate blocks of data that have been restored to the primary storage.

A system and method for automatic data mapping of a source object to a target object. Field maps can be automatically determined from the source and target objects, database platform, ETL maps, user-defined and data conversion rules, default values, or other pre-defined parameters. Where a change occurs in the source or target data structure, the present invention ensures proper mapping between the source and target data structures occurs, thus reducing the burden of exception handling on the user and preventing oversight in correcting improper mapping. The present invention can also be used by a compiler to generate SQL steps during compile-time processes to design field maps that can be stored as an application class.

The invention discloses methods and apparatus that facilitate efficient querying of tables referencing semistructured data such as digraphs and other domains with complex grouping structure. The invention methods enable meaningful indexing of the tables as well as rewriting of queries with respect to the structures.
