An endoluminal prosthesis and systems and methods for making the prosthesis are provided. In one example, a patterned graft material for a prosthesis includes a network of electrospun fibers. The network of electrospun fibers may include a plurality of continuous electrospun fibers. The fibers may be collected on a collector plate using an electrospinning process to form the network of fibers. The patterned graft material also may include a plurality of openings in the network of electrospun fibers. The plurality of openings may be arranged in a pattern. The network of electrospun fibers may include a plurality of edges, each surrounding a corresponding one of the plurality of openings. Each of the plurality of edges may include at least one electrospun fiber of the network of electrospun fibers. A majority of the electrospun fibers of the plurality of edges may be continuous at the edges.

A Thumbtrap is an ipad accessory, that enhances individual and multi-player game play. It is a non-permanent, reusable vinyl cling that sticks to the smooth glass screen of the ipad without use of adhesives. When placed over an onscreen game control button, a Thumbtrap acts like a small fence that prevents the thumb drift that inevitably occurs during intense game play, and guides the thumb into specified zones over an onscreen button for better button contact accuracy. Thumbtraps can be used with several existing ipad games.

Described is a metal sheet for a metal sheet assembly, in particular for a bottom plate of a distribution panel of an electrical switchgear. The metal sheet assembly includes at least one opening for conducting a cable therethrough. The metal sheet is provided with at least one cutout on the longitudinal side, wherein the metal sheet assembly is composed of at least two metal sheets and the two metal sheets abut along the longitudinal side. The two metal sheets are oriented, relative to each other, in such a way that the cutouts in the two metal sheets are arranged opposite each other.

In the case of a fiber composite component for energy absorption in the event of a crash for an aircraft or spacecraft, the fiber composite component is formed as a laminate construction made of CFRP layers and at least one integrated metal foil portion which is corrosion-resistant with respect to the CFRP layers. A fuselage structure portion of an aircraft or spacecraft is formed using at least one fiber composite component of this type. An aircraft or spacecraft comprises a fuselage structure portion of this type.

Laminates are described herein. A laminate is characterized in that the laminate contains a water-absorbing polymer known as a super-absorbent polymer (SAP) between one or more elastic interplies, wherein the interplies consist of sheetlike lengths of material which are firmly bonded together on the outside surface of individual threads, strands or bands and this laminate is extendable essentially transversely to the production direction and shirred in a relaxed state, and the elastic interplies contain many individual sections or cassettes of superabsorbent and create room for the expansion of the laminate on fluid imbibition perpendicularly to and within the manufacturing plane.

A knockout can be removed from a parent part in a sheet metal structure by removing one or more twistable tabs located on a perimeter of the knockout. A tab is defined by a region of sheet metal within a perimeter consisting of a first and a second cut. The first and second cuts extend through the sheet metal along first and second paths. A first neck extends between the first end of the first cut and the first end of the second cut and between the tab and the parent part. A second neck extends between the second end of the first cut and the second end of the second cut and extends between the tab and the knockout. To remove the tab, the tab is rotated such that the two necks twist about an axis between them, until torsional fatigue fractures the necks.

摘要:
When a multilayer ceramic substrate with a cavity is reduced in thickness, a bottom wall portion defining the bottom of the cavity is reduced in thickness, thereby leading to the problem that the bottom wall portion is likely to be broken. A bottom wall portion defining a cavity of a multilayer ceramic substrate has a stack structure formed with a high thermal expansion coefficient layer sandwiched between first and second low thermal expansion coefficient layers. This configuration generates compression stress in the low thermal expansion coefficient layers during a cooling process after firing, thereby allowing the mechanical strength at the bottom wall portion to be improved.
