Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to great an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The electrodes are insulated from each other.

IPC: H04N5/93

Abstract: A method for recording pushed interactive data streams of a program. A pushed data stream is broadcast to a receiving station. The data stream includes one or more data objects. The data stream may also reference to live data objects which are intended for immediate consumption and become obsolete thereafter. The data stream may include a file table and object properties corresponding to the data objects. When the data stream is received by the receiving station, the individual data objects are extracted from the data stream. The data objects, accompanying object properties and the file table are then stored on a storage device. Data objects which are external to the data stream or to the program (e.g., data objects from other carousels) are retrieved and are also stored. Live data objects are not stored, but references to these data objects are stored, so that when the program is replayed, current versions of the referenced live data objects can be used. A program not being recorded may contain data objects which are flagged to be cached which are recorded automatically. Consequently, other programs may subsequently access them from the recording when they are played.

Abstract: A polymerase protein originating from a dsRNA virus catalyzes RNA synthesis using ssRNA, dsRNA, ssDNA, or dsDNA templates. Such a polymerase can be purified from a dsRNA virus, and a protein having the amino acid sequence of such a polymerase is useful in methods and kits for in vitro RNA synthesis. A polymerase of the invention is processive, has very high RNA-polymerization rate and does not require primer for the initiation of RNA synthesis, although it is also able to initiate RNA synthesis in the presence of a primer. Primer-independent synthesis is especially useful in amplifying RNA for quantitation of RNA species in the sample and their identification by direct sequencing. This methodology is especially useful in detecting pathogenic parasites and differences in gene expression levels associated with diseases.
