Abstract: The invention relates to pumping engineering, mainly to downhole jet production units. The inventive downhole jet unit comprises a packer, a pipe column and a jet pump. An active nozzle and a mixing chamber are axially arranged in the body of the jet pump, and a pass channel provided with a mounting face for a sealing assembly with an axial channel is embodied therein. Said unit is also provided with an irradiator and a receiver transformer of physical fields. Said receiver transformer is arranged on the side of entry of a liquid pumped from the well into the jet pump and mounted on a cable passing through the axial channel of the sealing assembly. The output of the jet pump is connected to the pipe column above the sealing assembly. The input of a channel for feeding the pumped out medium of the jet pump is connected to a space around the pipe column below the sealing assembly. The input of a channel supplying a working medium to the active nozzle is connected to a space around the pipe column. A number of channels for feeding the pumped out medium are embodied in the body of the jet pump.  The invention makes it possible to optimise dimensions of various elements of the unit, thereby increasing the operating reliability of the downhole jet unit.

Title: System and method of deskew buffering signals
Inventor: KANG INYUP
IPC: H04B1/7117
Filed: 2001-11-16
Granted: 2008-04-01
Abstract: A deskew buffer 410 arrangement in a CDMA receiver allows for accurate combining of symbols from a plurality of demodulator fingers, 402 and 404, without any symbol losses when the data rate is changed. A single deskew buffer 410 is coupled to a plurality of demodulator fingers, each of which demodulate an assigned multipath. The symbols are written into the deskew buffer 410 according to a PN count value modified by a predetermined bit pattern. The demodulator finger is able to demodulate a plurality of data rates corresponding to a plurality of Walsh lengths. Each data rate is assigned a corresponding deskew index. The PN count value represents an address within the deskew buffer 410. The lower bits of the PN count, where the number of bits corresponds to the deskew index, are truncated and replaced with the predetermined bit pattern. In one embodiment the predetermined bit pattern is all ones.

Abstract: A method for manufacturing a composite pipe formed by an outer metallic pipe with a plastic material inner lining is described. The pipe exhibits resistance to internal and external pressure, and resistance to aggressive agents defined by the plastic material. The inner lining is a prefabricated plastic material pipe inserted into the metallic pipe, interposing a means able to transmit internal pressure within the plastic material pipe to the metallic pipe. The method comprises the steps of:  grasping said prefabricated plastic material pipe by one end; and dragging it into the metallic pipe; simultaneously injecting a setting filling material by means of an injection tool into the gap between the plastic material pipe being inserted and the corresponding metallic pipe surface; dragging said setting filling material until substantially filling the gap between both pipes; and letting the filling material set.     Also described is the use of said composite pipe.

Title: Data transmission between remote and central monitoring unit
Inventor: SEVERE LON M
IPC: A61G99/00
Filed: 2002-04-22
Granted: 2009-06-30
Abstract: A patient is monitored using a monitoring apparatus including a remote monitoring unit associated with the patient and having a sensor that measures a physiological characteristic of the patient, a central unit, and a communications device which selectively establishes a communications link between the remote monitoring unit and the central unit. The remote monitoring unit obtains a monitored data set for the patient, analyzes the monitored data set to obtain a derived data set from the monitored data set, and determines from the derived data set that communication with the central unit is required. A communications link is established with the central unit, and the remote monitoring unit transmits to the central unit an initially transmitted data set related to the monitored data set. The central unit analyzes the initially transmitted data set and instructs the remote monitoring unit as to any additional transmitted data set related to the monitored data set that is to be transmitted from the remote monitoring unit to the central unit and a time at which the additional transmitted data set is to be transmitted.

Abstract: Methods for communicating between an application and an ink divider object (which stores ink strokes to be divided into groups) may include: (a) issuing a divide request to the ink divider object, optionally by the application; (b) in response to the divide request, calling a divide method, which groups the stored ink strokes into one or more groupings of strokes having a first predetermined granularity (e.g., words, lines, paragraphs, sentences, drawings, etc.); and (c) making information regarding the one or more groupings of strokes available to the application. This "information" made available to the application may include, for example, the actual groupings of the strokes, the number of stroke groupings having the first predetermined granularity, machine generated text corresponding to the stroke groupings, or the like. The results of the divide method may be stored in an ink division result object. In some examples, the ink division result object may include the originally divided strokes and allow retrieval of groupings of strokes of various different granularities. This invention also relates to systems for performing the above methods and various data structures used in performing these methods.

Title: Compositions and methods for the modulation of gene expression in plants
Inventor: VANCE BOWMAN VICKI
IPC: C12N15/11
Filed: 2003-07-21
Granted: 2011-10-18
Abstract: Compositions and methods for modulating nucleotide sequence expression, particularly for modulating gene expression in plants, are provided. The compositions comprise precursor RNA constructs for the expression of an RNA  precursor. The precursor RNA construct comprises a promoter that is expressed in a plant cell driving the expression of a precursor RNA having a microRNA.  The miRNA is complementary or partially complementary to a portion of a target gene or nucleotide sequence and function to modulate expression of the target sequence or gene. In this manner, the RNA precursor construct can be designed to modulate expression of any nucleotide sequence of interest, either an endogenous plant gene or alternatively a transgene. The precursor RNA  constructs may be used in combination with modulators to enhance the effect on gene expression. Expression of a modulator in the presence of the precursor RNA alters the accumulation of miRNAs and thus enhances the regulatory capabilities of miRNAs. The invention further comprises the use of a modulator to control gene expression via both siRNA and the miRNA pathway. Transformed plants, tissues, cells and seeds are also provided.

Abstract: A "Media Identifier" operates on concurrent media streams to provide large numbers of clients with real-time server-side identification of media objects embedded in streaming media, such as radio, television, or Internet broadcasts. Such media objects may include songs, commercials, jingles, station identifiers, etc. Identification of the media objects is provided to clients by comparing client-generated traces computed from media stream samples to a large database of stored, pre-computed traces (i.e., "fingerprints") of known identification. Further, given a finite number of media steams and a much larger number of clients, many of the traces sent to the server are likely to be almost identical. Therefore, a searchable dynamic trace cache is used to limit the database queries necessary to identify particular traces. This trace cache caches only one copy of recent traces along with the database search results, either positive or negative. Cache entries are then removed as they age.
