The invention discloses a sawbuck. The sawbuck comprises a rectangular base, from the base there are upwardly projecting side walls, on two sides there is an outer and inner wall. The distance between the inner and outer walls define an opening, the said opening is for holding slats, the slats are positioned for holding logs, the logs are placed across the facing side walls in between the slats.

An apparatus and method for additive fabrication which helps to prevent the newly hardened layer from being separated from the previously formed layer of the object while the foil is peeled from the newly hardened layer is provided. In one embodiment, use of a peel angle helps prevent the newly hardened layer from being separated from the previously formed layer during peeling by distributing the peeling force so that less of the z-direction component of the peeling force is applied to the newly hardened layer. In another embodiment, the object can be oriented to initiate the peel at an area, of the object which results in a lesser initial peeling force applied to the newly hardened layer.
摘要:
A system and method for layer-by-layer production of an object is provided. The system includes a construction shape having a carrying surface adapted for carrying a layer of build material, a plate having a holding surface adapted for holding an object in an object build area, a moveable reservoir having a plurality of containment surfaces defining a containment area adapted for containing a volume of build material within the moveable reservoir, and an exposure unit adapted for exposing at least a portion of the layer of build material in the object build area so that the portion of the layer of build material solidifies to form a solidified layer of the object.
摘要:
Incorporating antimicrobial metals, such as silver salts, into an anticorrosion coating provides both excellent antimicrobial protection and surprisingly improves the anti corrosion activity as well, proving anti corrosion coatings effective as thin films and well suited for coating medical devices. Suitable binder polymers for the coating include but not limited to polyelectrolytes containing charged and/or potentially chargeable groups and polymers containing hydrophilic entities.

The present invention provides a method of forming a drug eluting stent, the method comprising coupling a stent framework to a mandrel, inserting the mandrel with stent framework into an open die, the die including a forming surface including a plurality of raised indentation forming portions; closing the die against the stent framework; pressing the raised indentation portions into the stent framework to form indentation in the stent framework; and inserting at least one drug polymer into the indentation formed in the stent framework.
摘要:
A radio access network includes a transport network layer; a radio network layer having a layer 2 network for communicating between entities within the radio network layer by exchanging datagrams having a predetermined format used only within the radio network layer. Accordingly, the present invention provides for a true decoupling at layer 2 between the radio network layer and the transport network layer.Addressing at layer 2 can enable both connectionless and connection oriented using an overlay connectivity model. Layer 2 in the radio network layer is implemented as an Ethernet network.
摘要:
The present invention relates to injectable compositions comprising biocompatible, swellable, hydrophilic, non-toxic and substantially spherical microspheres useful for tissue bulking. The invention also relates to methods of tissue bulking, particularly for the treatment of Gastro-esophageal reflux disease, urinary incontinence, or urinary reflux disease, using the injectable compositions.

A method of deploying a stent-graft in a curved vessel includes deploying an expandable tip to center a proximal end of the catheter containing a stent-graft in the curved vessel. A sheath is retracted to expose the stent-graft and the stent-graft self-expands into the curved vessel. By centering the catheter containing the stent-graft prior to deployment with the expandable tip, the accuracy of stent graft placement within the curved vessel is improved.
