The tissue repair device can include any one or combination of: a needle defining a lumen that extends through a distal end of the needle adjacent a tip thereof a deformable first anchor disposable in the lumen proximal to a distal end of the needle; a deformable second anchor disposable in the lumen adjacent but proximal of the first anchor; and a member positioned within the lumen and engageable with at least one of the first anchor or the second anchor.

Abstract: Disclosed herein are bicomponent fibers comprising first and second polymer components present in distinct portions of the cross section of the filament, wherein the first polymer component of the filaments is partially crystalline and serves as the matrix component of the filaments and the second polymer component of the filament is amorphous and serves as the binder component of the filaments, and wherein the fibers exhibit a single melting peak as evidenced by a differential scanning calorimetry (DSC) trace. Also disclosed herein are methods of making bicomponent fibers and nonwoven fabrics.

Abstract: A nonwoven fabric is provided having a plurality of semi-crystalline filaments that are thermally bonded to each other and are formed of the same polymer and exhibit substantially the same melting temperature. The fabric is produced by melt spinning an amorphous crystallizable polymer to form two components having different levels of crystallinity. During spinning, a first component of the polymer is exposed to conditions that result in stress-induced crystallization such that the first polymer component is in a semi-crystalline state and serves as the matrix or strength component of the fabric. The second polymer component is not subjected to stress induced crystallization and thus remains in a substantially amorphous state which bonds well at relatively low temperatures. In a bonding step, the fabric is heated to soften and fuse the binder component. Under these conditions, the binder component undergoes thermal crystallization so that in the final product, both polymer components are semi-crystalline.

Abstract: A media path crossover for a printing system includes a first crossover pathway on which sheets of print media are conveyed across a crossover junction without interruption and a second crossover pathway on which sheets of print media are conveyed across the crossover junction without interruption. The second crossover pathway intersects the first crossover pathway at a crossover junction. The first crossover pathway comprises a first input path and a first output path and the second crossover pathway comprises a second input path and a second output path. At least the first input path includes a first access panel, whereby a sheet can be cleared therefrom while continuing conveyance of media along the second crossover pathway.

Abstract: Nonwoven fabric fabrics suitable for undergoing pleating to form filtration media are provided. The fabrics generally include at least three layers. The fibers forming the inner layer has a cross section providing greater stiffness, while the fibers forming the outer layers have a cross section providing greater durability. The resulting fabrics provide improved particulate holding and pressure drop characteristics at no sacrifice to durability.

Abstract: A feeder tray having movable front section to allow for loading of stock without having to load over the front section of the tray.

Abstract: A user interface is provided for a printer having a finishing device having a maximum physical sheet capacity and being operable at an operational sheet capacity equal to or less than the maximum physical sheet capacity, a marking device which applies marks to sheets of media supplied thereto and outputs the same to the finishing device which receives the sheets from the marking device. The user interface comprises a display and an input device. The display communicates to an operator of the printer a selectable operational capacity of the finishing device whereby the operator may select a selectable operational capacity, a selectable option to override the selectable operational capacity and a prompt to override the operational capacity. The input device permits the operator of the printer to indicate selections.

Abstract: The invention relates to a ball-limiting metallurgy (BLM) etching system and process. The BLM stack is provided for an electrical device that contains an aluminum layer disposed upon a metal first layer. A metal upper layer is disposed above the metal second layer, and an alternative metal third layer is disposed between the metal second layer and the metal upper layer. The etching system and process utilizes an etching solution that includes a nitrogen-containing heterocyclic compound, an ammonium hydroxide compound, an oxidizer, and a metal halide compound. Etching conditions prevent any metallization that is dissolved from redepositing, thus avoiding lowered yields.

Abstract: In a printing apparatus or copier, a vertical portion of a paper path is formed between two flat members. To remove jammed paper from the path, one of the flat members is moved, by a hinge, from the other, releasing any sheet in the path. Released sheets drop down the path and land on a bottom structure. The bottom structure causes a sheet landing thereon to incline away from the hinge, so that a user can remove the sheet without having to reach far into the path.
