摘要:
A peritoneal-based (“bloodless”) artificial kidney processes peritoneal fluid without need for additional fluids (“waterless”). Fluid is separated into a protein-rich stream and a protein-free stream. The protein-rich stream is regenerated using a sorbent assembly, and its protein composition can be modified by removal of selected protein(s) (“dialysate-pheresis”). It is then reconstituted with additives and returned into the peritoneal cavity, thereby reducing protein-loss and providing oncotic-pressure for ultrafiltration. The protein-free stream is used to produce free water, and an alkaline or acid fluid for optimization of the composition of the regenerated stream. The unused protein-free stream can be used to “reverse flush” the separator to maintain its patency and the excess discarded for fluid-balance regulation. Compared to prior art, immobilization of urease allows more protein rich fluid to be regenerated and re-circulated into the peritoneal cavity for toxin removal and allows practicable development of portable and wearable artificial kidneys.

摘要:
A peritoneal-based artificial kidney processes peritoneal fluid without need for additional fluids. Spent dialysate is separated into a protein-rich stream and a protein-free stream. The protein-rich stream is regenerated using a sorbent assembly, and its protein composition can be modified by removal of selected protein(s). Alternatively, the spent dialysate is first processed in a sorbent assembly and then separated into the protein-rich and protein-free streams. Immobilization of urease allows more protein rich fluid to be regenerated and re-circulated into the peritoneal cavity for toxin removal and allows practicable development of portable and wearable artificial kidneys.

The invention provides a fuel additive compound represented by the general formula (I) wherein n is zero or an integer from 1 to 20 and in each succinic acid moiety one of R1 and R3 is a C3—C80 internal olefin moiety, and the other of R1 and R3 is hydrogen. Additive compositions containing such compounds have low viscosity and are useful in increasing the lubricity of middle distillate fuels.

A method for forming an electrical interconnect overlying a buried contact region of a substrate is characterized by a deposition of a first polycrystalline silicon layer and the patterning and etching of same to form a via. The via is formed in the first polycrystalline silicon layer to expose the substrate and a second polycrystalline silicon layer is formed in the via to contact the substrate. Portions of the second polycrystalline silicon layer overlying the first polycrystalline silicon layer are removed eliminating any horizontal interface between the two polycrystalline silicon layers. The first polycrystalline silicon layer remaining after the etch is then patterned to form an electrical interconnect.

A transport interface (10) provides add drop multiplex functionality and termination requirements for the transportation of network traffic. The transport interface (10) includes high speed units (12), broadband interfaces (16), and SONET formatters (18). Each high speed unit (12), broadband interface (16), and SONET formatter has redundant protection pairs (A and B). The high speed units (12), broadband interfaces (16), and SONET formatters (18) communicate with each other by in-band datalinks (40). The redundant protection pairs (A and B) communicate with one another by protection pair datalinks (42). The in-band datalinks (40) and the protection pair datalinks (42) provide an effective means for performing protection switching within the transport interface (10) in the event of component failure. The in-band datalinks (40) are generated out of available or consumed bytes within either a section overhead (32) or a line overhead (34) of SONET OC-N frame (30). The protection pair datalinks (42) provide communication capability over a common control communications interface. The in-band datalinks (40) and the protection pair data links (42) work together to provide a smooth transition from one component to another in the event of a protection switch.

A high-speed communication system (32) comprises a serial-to-parallel converter (38) for arbitrary converting a stream of serial data to a stream of arbitrarily aligned parallel data. A pattern detector (44) is coupled to the serial-to-parallel converter (38) for detecting a predetermined pattern from the stream of parallel data and generating a phase signal responsive to the detection of the pattern. An aligner (42) coupled to the pattern detector (44) generates an aligned stream of parallel data responsive to the phase signal.

In the provided architecture, one or more multi-threaded processors may be combined with hardware blocks. The resulting combination allows for data packets to undergo a processing sequence having the flexibility of software programmability with the high-performance of dedicated hardware. For example, a multi-threaded processor can control the high-level tasks of a processing sequence, while the computationally intensive events (e.g., signal processing filters, matrix operations, etc.) are handled by dedicated hardware blocks.
