20110270412 | FABRICATION OF A VASCULAR SYSTEM USING SACRIFICIAL STRUCTURES - The first aspect of the present invention is directed to a method of producing a vascular network preform (VNP). This method involves forming a network of elongate fibers and at least one elongate structure from a sacrificial material. The diameter of the elongate structure is greater than that of the elongate fibers. The network of elongate fibers is placed in contact with at least one elongate structure either following or during forming the network of elongate fibers or forming the at least one elongate structure. A matrix is applied around the network of elongate fibers, in contact with the at least one elongate structure. The network of elongate fibers and elongate structure, within the matrix is sacrificed to form a preform. The resulting preform contains a vascular network of fine diameter tubes in contact with at least one elongate passage having a diameter greater than that of the fine diameter tubes. The resulting solid preform and methods of using it are also disclosed. | 11-03-2011 |
20130066045 | PH-SENSITIVE SACRIFICIAL MATERIALS FOR THE MICROFABRICATION OF STRUCTURES - Methods for microfabricating composite materials and composite materials prepared there from are described herein. The sacrificial material can be etched or patterned to create a two-dimensional and/or three-dimensional sacrificial material structure. The resulting sacrificial material structure can be embedded in one or more embedding materials. The sacrificial material(s) are materials whose solubility can be altered by application of a stimulus typically pH, and/or temperature, light, pH, pressure, presence of absence of ions, and combinations thereof. The embedding materials can contain one or more additives that modify one or more properties of the embedding materials, such as degradation properties, porosity, mechanical properties, viscosity, conductive properties, and combinations thereof. The composite materials can be used in tissue engineering, drug screening, toxin detection, drug delivery, filtrations, bioseparations, and as microfluidic devices for fluid mixing and structural repair. | 03-14-2013 |
20130118228 | STRESS-BASED SENSOR, METHOD, AND APPLICATIONS - A composite, analyte sensor includes a substrate; a micro- or nano-electro-mechanical (MEMS; NEMS) resonator that is coupled to the substrate at least two edge locations (i.e., it is at least doubly-clamped) of the resonator, wherein the resonator is in a statically-buckled state near a buckling transition point of the resonator; and a chemically-responsive substance covering at least a portion of the surface of the resonator that will undergo a conformational change upon exposure to a given analyte. The resonator may be a double-clamped, statically-buckled beam (or bridge), a multiply-clamped, statically-buckled dome (or crater), or other resonator geometry. The sensor may include two or more at least double-clamped, statically-buckled, composite MEMS or NEMS resonators each operating near a buckling transition point of the respective resonator, and each characterized by a different resonant frequency. A method for sensing an analyte in ambient air. | 05-16-2013 |

20120203913 | METHOD AND SYSTEM FOR FEDERATION OF PROXY-BASED AND PROXY-FREE COMMUNICATIONS SYSTEMS - A method and system for federation of proxy-based and proxy-free communications systems is disclosed. In one embodiment, a computer-executable method comprises broadcasting a network address of a federation computer with an identification of the federation computer as a server for domains operating on a proxy-less protocol. The method includes establishing communications with a server on the network according to a proxy-less communications protocol to receive data bound for a destination domain that operates according to a proxy-based communications protocol and to receive data bound for a destination domain that operates according to a proxy-less communications protocol. Further, the method calls for establishing communications with a proxy on the network according to a proxy-based protocol to receive data bound for a destination domain. | 08-09-2012 |
20120254326 | METHOD AND SYSTEM FOR ADVANCED ALIAS DOMAIN ROUTING - A method and system for advanced alias domain routing are disclosed. According to one embodiment, a computer implemented method comprises receiving an incoming message from a first unified communications server, the incoming message comprising source address data, destination address data, and digital content. A real address of a destination address is computed by using the source address data, and an alias address of a source address is computed by using the destination address data. The incoming message is processed, wherein processing the incoming message includes enforcing policies. An outgoing message is generated comprising the digital content, the real address and the alias address. The outgoing message is transmitted to a second unified communications server. | 10-04-2012 |
