摘要:
An expandable prosthesis includes a self-expanding stent deployable between a substantially radially compressed configuration and a substantially radially expanded configuration. A biocompatible coating is attached to at least a portion of the outer surface of the self-expanding stent in the radially compressed configuration to inhibit radially expansion of the self-expanding stent to the radially expanded configuration. The biocompatible material is preferably integrally mounted to the self-expanding stent thus eliminating the need for a separate, independent delivery tube or sheath for maintaining the self-expanding stent in the radially compressed configuration during delivery of the self-expanding stent into a body vessel.

A method and apparatus for generating a Value Bearing Indicium (VBI) for on-line ticketing applications. A VBI may be generated by hashing user information to create a message digest that is used to create a digital signature. The digital signature is combined with the user information to create a VBI that can be validated by a variety of stand-alone or on-line methods. An on-line ticketing application using the VBI is described.

Disclosed is a method, system, and program for providing access to spatial data. A request for data is received. Enterprise and third party data are integrated. The integrated data is processed. Spatially referenced results are generated using the processed data. The spatially referenced results are returned in response to the request.

Provided is a technique for evaluating risk associated with underwriting an insurance policy (FIG. 1). At least one location to be covered under the insurance policy is received (FIG. 3, block 320). Risk associated with the location is automatically assessed (FIG. 3, block 338). It is determined whether to underwrite the location based on the assessed risk (FIG. 3, block 340). Also provided is a technique for proximity analysis (FIG. 54). Selection of a proximity center is received (FIG. 55). A function is executed with the proximity center to determine target data items that fall within a proximity area around the proximity center. The target data items are spatially represented.

Resilient electrical interconnects are provided which have a non-uniform cross section which achieves an increased range of deflection and a predetermined relationship between compression force and deflection of the interconnect, and between resistance and deflection of the interconnect. A smaller cross sectional area decreases the spring rate, or compression force, of the interconnect during compression. Increased range of deflection and reduced spring rate enables improved compensation for surface irregularities and facilitates mounting of integrated circuit or other devices having large arrays of interconnects. The non-uniform cross section is provided by a single or compound slope, or alternatively a nonlinear curve, from the end of smaller cross-section to the end of larger cross-section.

Provided are a method, system, and program for rendering information on network infrastructure. A selection of customer sites is received and a database is queried to determine geographical locations of the selected network sites. A graphical user interface is rendered including representations of the selected customer sites in a map at the geographical location of the selected sites in the map. Selection is received of at least one network service provider (NSP). The database is queried to determine network infrastructure of the selected NSP and geographical locations of the determined network infrastructure. Representations are rendered of the determined network infrastructure in a map at the determined geographical locations of the determined network infrastructure to render a visualization of the geographical locations of the selected customer sites and network infrastructure of the selected at least one NSP in the map.
摘要:
A radially deployable covered stent that predictably and dependably expands to an increased diameter state at relatively low deployment pressures while concomitantly minimizing the risk of tearing of the stent covering during expansion. The stent covering includes an inner cover and an outer cover that are bonded together through and around the stent structure to cover the stent. The stent cover is constructed from expanded polytetrafluoroethylene (ePTFE) having a structure of nodes interconnected by fibrils. The stent covering has a radial thickness of at least about 0.008″ and an average internodal distance (IND) of at least about 100 microns when the stent is in the reduced diameter, unexpanded state. The covered stent deploys at an average deployment pressure of less than or equal to about 10 atm. A method for covering a stent structure according to the present invention includes placing a compression member in the form of a tubular sleeve over the outer cover and heating the compressed covered stent to bond the inner cover to the outer cover. An adhesive in the form of an aqueous dispersion of PTFE can be applied to either the inner cover or the outer cover to facilitate bonding of the inner cover to the outer cover.
摘要:
A flex connector assembly for connecting circuit boards has been provided that includes a housing having at least one cavity holding a preloaded spring exerting an outwardly-directed force toward top and bottom ends of the housing; at least one pressure support member located at one of the top and bottom ends, the pressure support member exerting an inwardly-directed force on the preloaded spring; and at least one flex circuit having a flex array arranged on one of the top and bottom ends; and at least one compressible socket having a socket array overlapping the flex circuit. The preloaded spring acts to compress the flex array and the socket array onto one another.
摘要:
The present invention provides an electrical and fluid interconnect for providing electrical connection between one or more circuits or electrical devices and a mateable circuit board or substrate, and for providing fluid coupling of a cooling fluid to permit fluid flow in relation to the electrical circuits or devices when mated to the circuit board or substrate. The fluid connector has a valve which in the absence of mating pressure is in a closed or off position. When mated to a fluid connector which is part of or coupled to the latch assembly, the valve is opened to permit fluid to flow.
