Title: Dual loop delay-locked loop
Inventor: JEONG DEOG-KYOON
IPC: H03L7/081
Filed: 1998-12-21
Abstract: A device and method for synchronizing a local clock to a reference clock. The device uses a frequency acquisition loop (418) and a phase acquisition loop (420).

The frequency acquisition loop (418) comprises a first delay circuit (400) adapted to delay the reference clock (REF-CLK) by an adjustable delay period which is selected from a plurality of non-adjustable delay periods by a first delay controller (404). The latter preferably comprises a cross-sensing phase detector pair (504) and a control logic (506). The phase acquisition loop (420) comprises a second delay circuit (402) adapted to delay the intermediate clock (FCLK', BCLK') by an adjustable delay period by a second delay controller (406).

Title: Methods and compounds for the genetic treatment of hyperlipidemia
Inventor: ROY-CHOWDHURY JAYANTA
IPC: C12N15/11
Filed: 1998-08-28
Abstract: The present invention concerns the introduction of specific alterations in the genes that encode three apolipoproteins, Apo A1, Apo B and Apo E. The alternations in Apo A1 introduce a cysteine residue so the disulfide cross-linked Apo A1 homodimers and Apo A1/A2 heterodimers can be formed. The alterations in Apo B introduce stop codons or frame shift mutations that cause the production of a truncated Apo B protein. The alterations in Apo E  introduce specific point mutations that have been identified as protective.  The production in the liver of a subject of these altered proteins reduces the risk of the subjects developing atherosclerosis. In one embodiment the genetic alterations are introduced by use of chimeric, mixed RNA/DNA, duplex oligonucleotides.

Inventor: BARANOV VLADIMIR I
IPC: G01N27/62
Filed: 2000-11-23
Abstract: A spectrometer apparatus and method provides a modulated stream of ions which can be from the source that is inherently modulated, or a continuous source that is subject to some modulation or gating technique. The ions are then delivered as a pulse or a series of pulses of ions into a pressurized reaction cell, in which reaction and/or collision with gas in the cell occurs.      The ions are then pass from the pressurized cell into a mass analyzer for detection. The mass analyzer, ion detector or ion induced signal processing system are operated in such a manner that only ions that arrive at the detector in a period of time set relatively to the time of release of pulses of ions are used for analysis. It has been found that by careful selection of this period, enhanced specificity can be achieved and the effect of interference ions can be reduced.

Abstract: The present invention is directed to a method and apparatus for forming soot  used in making glass, and in particular, optical waveguides. A liquid precursor (66) is first fed into orifice (52) of a liquid orifice insert (48 ) within an injector (44) positioned within an atomizing burner assembly, and is thereafter discharged from the injector into a pressurization chamber (56). An atomization gas (70) is also fed into the pressurization chamber (56) to mix  with the liquid precursor liquid stream (68) which breaks into droplets (76) . The liquid precursor and atomization gas are forced under pressure out of an  atomization orifice (32) on the face of the burner (30) assembly. Flame gas (74), reaction gas (84) and shield gas (82) are ejected from burner orifices  (40, 38, 36 and 34) to produce the flame. The atomized liquid precursor thus  discharged is fed into the flame (72) produced at the face of the burner assembly where the atomized liquid precursor reacts with the flame to form soot (78) on a rotating mandrel (80).

Title: Dpoae measurement system and method
Inventor: KARIMI ZIARANI ALIREZA
IPC: A61B5/12
Filed: 2001-05-04
Abstract: A new method of DPOAE signal level measurement based on a recently developed family of nonlinear adaptive algorithms is presented. Three core units are employed to extract and measure the two artifacts and the DPOAE signal. Each core unit, which can be any of the three members of a new family of signal processing algorithms, has the capability to lock on and track the time variations of a specified sinusoidal component of its input signal. The core units have very simple structure while maintaining very good perfor-mance in noisy environments in terms of stability and convergence speed.  Performance of the present method is demonstrated with the aid of computer simulations. The present method features structural simplicity which renders it suitable for both software and hardware implementation. It offers extremely high noise immunity and requires shorter measurement time than conventional methods.
