Abstract: A method of accelerated aging of bioresorbable polymer scaffolds including exposing the scaffold to water is disclosed. The scaffold is exposed to water at a controlled temperature for a selected aging time. The functional outputs, such as radial strength, expandability, and % recoil obtained from aged scaffolds predict those of real-time aging of the scaffold. The accelerated aging factor, which is the required shelf life divided by the aging time, is significantly higher for poly(L-lactide) scaffolds tested than thermal aging.

Abstract: A printing system treats the surface of three-dimensional objects to be printed to improve the printing of the articles of manufacture. The system includes a surface treatment module that is positioned to part of the printing process and to treat the object surfaces prior to the surfaces being printed. The treatment of the surfaces within the module include operating an abrasive device to remove material from an object surface and to apply solvent to the object surface to clean the surface.

Abstract: What is disclosed is an object holder for securely retaining a 3-dimensional object while it is being printed in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder comprises a frame configured to slideably traverse a support member positioned parallel to a plane formed by at least one printhead configured to eject marking material on to a surface of an object. A flexible belt is positioned around an inside of the frame to form a circle. One end of the belt is fixed to the frame. An opposite end of the belt passes through an opening in a side of the frame. Pulling the belt through the opening tightens the belt encircled around the object in the frame. A lock prevents the belt from loosening after it has been pulled tight.

Abstract: There are described methods and apparatus for scrambling digital content, such as video or audio content, by dividing the digital content into blocks set out in an original arrangement, and reordering the blocks from the original arrangement to a scrambled arrangement. Additional manipulation transforms such as rotations and reflections may be applied to individual blocks. A subsequent compression step may then be carried out. Methods and apparatus for carrying out corresponding descrambling of digital content are also described.

Abstract: What is disclosed is system which facilitates the application of a mark to a surface of an object in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the present marking system. The present marking system comprises a camera for capturing an image of an object retained by an object holder configured to slideably traverse a support member positioned to be parallel to a plane formed by at least one printhead configured to eject in onto a surface of the object. A processor receives an image of an object held and communicates the image to a display. A mark to be printed on the object is retrieved and overlaid on the object in the image. A location of the overlaid mark is determined and communicated to a controller which causes the printhead to print the mark on the object at the location.

Abstract: What is disclosed is an object holder for securely retaining an object while it is being printed in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder comprises a shuttle mount configured to slideably traverse a support member positioned parallel to a plane formed by at least one printhead configured to eject marking material on to a surface of an object. A memory foam is attached to the shuttle mount. A vacuum pump is used to withdraw a volume of air through a hole in the memory foam such that, a difference in air pressure causes an object to be pressed against the face of the memory foam causing the foam to partially deform to the object's shape.

Abstract: A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by one or more of a mechanical interference fit, a polymer coating or melt, and/or by friction. The marker can take the form of a bead, rivet or snap-in marker, or a tube deformed when attached to the strut. The strut is made from a tube. The strut has a thickness of about 100 microns.

Abstract: A disconnect fitting adapted for use with a phase changing composition including a fitting base having a first fitting base end, a second fitting base end and a fitting base opening therebetween, a pin capture disposed within the fitting base opening, a displaceable pin secured within the pin capture, a fitting socket having a first fitting socket end, a second fitting socket end, a fitting socket opening therebetween, the second fitting socket end secured to the second fitting base end, and a valve at least partially disposed within the fitting socket opening. When the displaceable pin is in an unloaded condition, the displaceable pin extends in a direction of the second fitting base end, and when the displaceable pin is in a loaded condition, the displaceable pin is compressed in a direction of the first fitting base end. The pin capture permits passage of the phase changing composition through the fitting base opening when the displaceable pin is in the unloaded condition or the loaded condition.
