A system and method for integrated circuit design are disclosed to enhance manufacturability of circuit layouts through generation of hierarchical design rules which capture localized layout requirements. In contrast to conventional techniques which apply global design rules, the disclosed IC design system and method partition the original design layout into a desired level of granularity based on specified layout and integrated circuit properties. At that localized level, the design rules are adjusted appropriately to capture the critical aspects from a manufacturability standpoint. These adjusted design rules are then used to perform localized layout manipulation and mask data conversion.

Textile Components, such as upper members for articles of footwear, include: (a) a first portion having a first edge, wherein the first edge includes a first portion of material engaged with a first seam support material via a first thermoplastic material; (b) a second portion having a second edge, wherein the second edge includes a second portion of material engaged with a second seam support material via a second thermoplastic material; and (c) structure to engage the first and second edges in an abutting edge joint (such as a zig-zag stitch). The resulting textile components may be lightweight and breathable (e.g., due to use of lightweight upper fabric), having a comfortable fit (e.g., due to the abutting edge joint), while still providing a strong, stable, and durable construction (e.g., due to the presence of the seam support member(s)).

A quilting apparatus for enabling a user to freely move a stack of fabric layers across a planar bed relative to an actuatable stitch head. The apparatus includes a motion detector which detects the movement of the stack and controls the actuation of the stitch head. Consequently, the apparatus functions to synchronize the delivery of stitch strokes by the head with the manually controlled movement of the quilt material stack. This frees the user to move the stack over a wide range of speeds, to start or stop movement at will, and to guide the stack in any direction across the planar bed.

A method for stitching thread onto the wall of a tubular medical implant (preferably a graft) employs a sewing machine with an elongate bobbin or a needle on an elongate element, depending on whether it is desired to sew from the outside-in or the inside-out. A motor rotates and translates the implant, which is mounted on a hollow drum, relative to the needle.

A flat sheet of woven material includes warp yarns and weft yarns interlaced at substantially right angles to each other. A graft material is cut from the flat sheet of woven material such that the graft material includes a graft material longitudinal axis and the warp yarns are disposed at an angle relative to the graft material longitudinal axis. The warp yarns and weft yarns are not parallel to or perpendicular to the graft material longitudinal axis. The graft material is formed into the shape of an endoluminal prosthesis, such as by rolling opposing edges towards each other and securing the opposing edges to each other. The endoluminal prosthesis thus includes warp yarns disposed at an angle relative to the prosthesis longitudinal axis.

Ink jet printing is provided on large area substrates such as wide width textile webs. The printheads are driven by linear servo motors (633) across a bridge (630) that extends across the substrate. The timing of the jetting of the ink is coordinated with the motion of the printheads (640,641), so that the heads can be rapidly moved and the ink can be jetted while the printheads are accelerating or decelerating as they move on the bridge. Preferably, ultraviolet (UV) light curable ink is jetted and first partially cured with UV light (645,646) and then subjected to heating to more completely reduce uncured monomers of the ink on the substrate. Preferably, the heat is applied by contacting the substrate with a heated plate (661,662). Ink jet printing is provided using ultraviolet (UV) light curable or other curable composition or stable or other printable substance. In certain embodiments the UV ink has a dye-component therein. The ink is jetted onto a substrate, the composition is cured, then heated to set the dye. Sublimation dye-based UV ink printing onto polyester is preferred. A release layer of protective material (702,704), such as a TEFLON film or sheet, covers a substrate support (705,706). A porous substrate to be printed, such as a textile material (711), is supported on or above the support. Ink is jetted onto the substrate, with some of the ink passing through pores in the substrate and landing on the protective material. UV curable ink is preferably used and is exposed by UV light from a UV light curing head, which solidifies the ink on the substrate. The UV curing light has a long enough focal length to focus on the surface of the substrate and also, where it passes through pores in the substrate, on ink on the protective material, thereby solidifying the ink on the protective material. When the substrate is removed from the support, the solidified ink on the protective material may be wiped from the protective material. The protective material may be a coating on the support over which the substrate slides or a belt that moves with the substrate. A textile substrate may be preconditioned by singeing or shaving to remove fuzz from the fabric that could clog the printheads. A printhead cleaning station is also provided.

A method of applying stitching to an interior component is provided herein. The method including the steps of: a) penetrating an outer skin layer, a substrate layer and an intermediary layer of the interior component with an awl to form a piercing therethrough; b) retracting the awl from the outer skin layer, the substrate layer and the intermediary layer; c) inserting a needle through the piercing through the substrate layer, the intermediary layer and the outer skin layer to grasp a thread positioned on the outer skin layer; d) pulling the thread through the outer skin layer, the intermediary layer and the substrate layer; e) looping the thread with a previous stitch passed through the outer skin layer, the intermediary layer and the substrate layer; f) advancing the interior component to another position; and g) repeating steps a-f until a predetermined amount of stitches are applied to the interior component.
