Title: Vsb/qam receiver and method
Inventor: OH JI-SUNG
IPC: H04L27/06
Filed: 2001-02-26
Abstract: A vestigial sideband/quadrature amplitude modulation (VSB/QAM) receiver, which receives both a VSB signal and a QAM signal, and a method thereof are provided. The receiver has an analog-digital converter for A/D converting according to a frequency higher than the symbol frequency of a received signal; an interpolator for calculating a signal value on the original symbol location after a signal from the A/D converter is applied; a carrier wave restoration unit for restoring a carrier wave by selectively using an automatic frequency control (AFC) and a digital frequency phase locked loop (DFPLL) according to a VSB/QAM mode after a signal from the interpolator is applied; a timing processor for receiving a signal from the carrier wave restoration unit, detecting a timing error after making a symbol input time different according to a VSB/QAM mode, controlling the interpolator based on the detected timing error, and generating a restored clock; and a VSB sorter for extracting a VSB receiving symbol. Therefore, according to the receiver, by restoring a carrier wave with a restored symbol clock after restoring symbol timing in the front part of the carrier wave restoration unit, a frequency having low symbol rate can be used, correction of the distortions in a carrier wave can be quickly done, and requirement for additional hardware for receiving a VSB signal can be very smaller.

Inventor: KIM SIN-HEE
IPC: A61K47/36
Filed: 1999-08-25
Abstract: Biodegradable hydrogels are formed by photocrosslinking dextran-maleic acid monoesters in which the average degree of substitution of each glucose unit of each .alpha.-D-glucopyranosyl of dextran by maleic acid ranges from 0.60 to 1.6 and which have a weight average molecular weight ranging from 40,000 to 80,000 on a dextran basis. The hydrogels at pH 7 have maximum swelling ratios ranging from 500 to 1,500 percent. The hydrogels are characterized by increase in swelling ratio as average degree of substitution increases. The hydrogels are useful, for example, for drug delivery and solubility enhancers of drugs, as protective encapsulators of viruses used in gene therapy, and for conventional uses of hydrogels.

Abstract: A method for moving seismic streamers (16) or acoustic energy sources (22) through water (12) in marine geophysical operations. The equipment can be deployed or retrieved from one or more vessels (14, 20), and two or more tow vehicles (14) maneuver seismic streamers (16) through the water independently of a seismic vessel (20). Manned or unmanned tow vehicles (14) can tow the streamers ahead of, behind, or to the side of a seismic vessel (20), or can form an array independent of the seismic vessel. Tow vehicles (14) can be located at both ends to change the tow direction. The invention is particularly useful in customizing an array configuration, in reorienting the array at the end of each survey line, and permits deployment of receivers and sources in different combinations. By decoupling the tow vehicles (14) and streamers (16) from the source vessel (20), turning time at the survey region borders and the possibility of streamer entanglement is significantly reduced.
