Abstract:
A device and method of providing vascular intervention is provided. The method involves the steps of inserting a guidewire having a flexible tip into an iliac artery and into an aorta, inserting a sheath having an introducer therethrough, the introducer having an angulated flexible tip, into the iliac artery over the guidewire, wherein the angulated tip of the introducer is also inserted into the aorta, and pulling back the guidewire from the introducer so that the angulated flexible tip of the introducer falls over an aortic bifurcation into a contralateral iliac artery. A kit is also provided, the kit having a sheath, an introducer running through the sheath and extending past a distal end of the sheath, and a guidewire running through the sheath and introducer; the guidewire having a flexible tip at a distal end and a stiff portion proximal to the flexible tip.
Abstract:
A method for travel planning employing a computerized database query system, the method including user designation of at least one desired travel destination and system presentation to user of at least one proposed hotel, based on the user designation, the at least one proposed hotel in geographical proximity to or otherwise convenient to said travel destination.
Abstract:
The present invention deals with compositions utilized to demulsify wash liquors, tramp oils or coolants. The compositions of the present invention are useful per se as cleaning compositions. The ability to rapidly demulsify from a waste liquor solution allows rapid recovery of fats, organic components, paint residues, greases and oils and rapid passage of the effluent to a sewage treatment facility.

Abstract:
A method for executing instructions in a data processor and improvements to data processor design, which combine the advantages of regular processor architecture and Very Long Instruction Word architecture to increase execution speed and ease of programming, while reducing power consumption. Instructions each consisting of a number of operations to be performed in parallel are defined by the programmer, and their corresponding execution unit controls are generated at compile time and loaded prior to program execution into a dedicated array in processor memory. Subsequently, the programmer invokes reference instructions to call these defined instructions, and passes parameters from regular instructions in program memory. As the regular instructions propogate down the processor's pipeline, they are replaced by the appropriate controls fetched from the dedicated array in processor memory, which then go directly to the execution unit for execution. These instructions may be redefined while the program is running. In this way the processor benefits from the speed of parallel processing without the chip area and power consumption overhead of a wide program memory bus and multiple instruction decoders. A simple syntax for defining instructions, similar to that of the C programming language is presented.
Abstract:
A method and apparatus for prechecking (probing) the validity of an access request for writing result data to an external system prior to executing the instruction that generates the result is provided. This allows instruction execution to continue uninterrupted in the event that the write is allowed. The microprocessor's Address Unit issues a "probe" request to the Memory Management Unit (MMU) via an internal bus while saving the instruction's virtual address in a virtual address buffer local to the Address Unit. The MMU checks the validity of the "probe" request without converting the virtual address to a physical address and issues an access grant signal which is saved by the microprocessor's Execution Unit for subsequent use. The Execution Unit processes the data in parallel to the MMU checking the validity of the probe request. If the virtual address associated with the probe request resulted in an access grant signal, then the Execution Unit issues a write request while the virtual address previously stored in the Address Unit is sent to the MMU for translation to a physical address. Both the write data and the physical address are stored in a buffer in the microprocessor's Bus Interface Unit (BIU) for subsequent transfer to an external system. The data is then written to the external system at the physical address provided by the BIU.
Abstract:
A method for travel planning employing a computerized database query system, the method including user designation of at least one desired travel parameter and system presentation to user of at least one proposed travel region, based on the user designation, the at least one proposed travel region having geographical boundaries which are generally independent of political boundaries.
