A system for percutaneously inserting a prosthesis containing a biological replacement for a defective valve into an implantation site through a body lumen. The system contains a balloon catheter upon which a collapsable stent containing a venous valvular replacement is mounted. A protective shield is slidably mounted upon the catheter that is movable between a closed position over the balloon and an open position wherein the balloon can be inflated to expand the stent. A central lumen runs through the catheter that is formed of stainless steel. The central lumen provides a one to one torque ratio between the proximal end of the catheter and the distal end to enhance the steerability of the catheter. The vein of the replacement is reduced in thickness between 50% and 90% of its original size thereby considerably reducing the size of the replacement package when the stem is collapsed upon the balloon of the catheter.

Maintaining proper planarity of elements of a microelectronic component test system helps ensure reliable operation of the test system. Aspects of the invention provide test systems and methods for verifying planarity of, for example, a head and a support surface of a microelectronic component test system. In one exemplary method, a probe card is mounted to and electrically coupled to a head of a microelectronic component test system. The probe card has an array of probes. A contact surface of the support is moved with respect to the head and a change in contact condition of each of the probes is recorded in a first data set. The orientation of the probe card with respect to the contact surface is changed, the contact surface is moved with respect to the head again and a change in contact condition of each of the probes is recorded in a second data set.

A method of rendering a sequence of graphical objects, where two or more different renderers are available and one of the renderers is designated as a currently-used renderer, includes the steps of receiving a current object in the sequence of graphical objects, adding the current object to a set of recently-received objects, and checking whether any one of a predetermined group of patterns of objects is present in the set, each pattern having an associated indication of the suitability of the available renderers for the pattern, the suitability being dependent on a time taken to render the pattern. The method further includes the steps of determining a suitable renderer from the available renderers using a pattern and associated indication identified in the checking step, and switching from the currently-used renderer to the suitable renderer if the suitable renderer is different from the currently-used renderer.

Methods of determining which components and their capacities within a distributed computing environment are used for a transaction type can be performed faster and more accurately compared to conventional methods. In one embodiment by separating the transaction types into groups, regression can be performed faster on data collected because the data is less “polluted” by some or all other transactions types. Also, selection of transaction types within each group can reduce or eliminate colinearities in data between different transaction types. In still another embodiment, the distributed computing environment can be allowed to catch up between running each group of transaction types. Alternatively, if multiple instances of a component are present, transactions may be routed based on transaction type to reduce the impact. Data processing system readable media can include code that includes instructions for carrying out the methods.

An application or a portion thereof can be thought of as a container having a set of instruments with mathematical descriptions of relationships between the instruments and other portions of the application infrastructure. The set of instruments may include only those instruments determined to significantly affect or be significantly affected by an application or a portion thereof running within a distributed computing environment. Models can be generated to include those instruments that significantly affect or are significantly affected by the application or a portion thereof and their mathematical descriptions of relationships between those instruments. By using the models, portions of an application environment across tiers can be controlled in a more coherent manner to better achieve the business objectives of an organization. The methods and systems can also help to identify and correct potential problems that may not be seen when examining tiers or sub-tiers individually.

In the invention, a collection device includes a flow through micro scale plate arranged to collect analyte. The plate includes holes, and sorbent coating on contact surfaces of the plate. The holes pass analyte fluid flow, for example analyte vapor so that fluid flow for collection may be generally perpendicular to the sorbent plate. Preferred embodiment plates include an integrated heater trace. In preferred embodiments, a high substantially perpendicular flow is used for collection and concentration, and during desorption and delivery a low substantially parallel flow is used. The low flow is selected to meet constraints of a detector system.
