Abstract: A GMSK modulator includes a dual-port memory, an address generator and a signal provider, where the dual-port memory respectively outputs in-phase and quadrature phase waveform data to first and second ports in response to in-phase and quadrature phase waveform address signals, the address generator generates the in-phase and quadrature phase waveform address signals based on a differential encoded bit stream, the signal provider selects one of the in-phase and the quadrature phase waveform data in response to the differential encoded bit stream, and outputs continuous GMSK in-phase and quadrature phase channel signals, and the redundancy of the memory that stores the GMSK in-phase and quadrature phase waveform data may be reduced using the dual-port memory so that the size of the memory may be reduced.

Abstract: A digital photographing apparatus capable of more precisely obtaining a panoramic image than conventional cameras, a method of controlling the digital photographing apparatus, and a recording medium storing a program for executing the method. The method of controlling a digital photographing apparatus includes: obtaining a first image according to a user's signal; inverting the pixel values of a portion of the first image; obtaining a second image; and obtaining a third image by combining the first image and the second image.

Abstract: A microcavity-containing, resilient foam comprising a thermoplastic polymer; composite structures comprising such a microcavity-containing foam and a multiplicity of particles contained in such microcavities, preferably aqueous fluid absorbent particles; methods for preparation of such foam and structures; and disposable consumer articles incorporating such foams and composites. The aqueous fluid absorbent characteristics of the foam and composite structures render them useful in the fabrication of disposable consumer articles, in particular hygiene articles designed to rapidly absorb “insults” of bodily fluid thereby conducting such fluids away from contact with the skin of the wearer of the hygiene article. The useful articles include infant and children diapers, adult incontinence pants, feminine hygiene pads, pet urine-absorbent pads and mats, household cleaning pads, surgical drapery, and the like.

Abstract: The present invention relates to a process for preparing polythiophenes comprised of unit structures of the general formula 1: where R1 and R2 independently represent hydrogen or a C1˜C4 alkyl group, or together represent an optionally substituted C1˜C4 alkylene group, preferably an optionally alkyl-substituted methylene group, an optionally C1˜C4 alkyl- or phenyl-substituted 1,2-ethylene group, a 1,3-propylene group or a 1,2-cyclohexylene group. More specifically, the process according to the present invention is characterized by the fact that it is performed by cationic polymerization from 2,5-dihalothiophene in the presence of an acid catalyst, such as Lewis acid, protic acid, oxygen acid, or polymeric acid. The conductivity of the resulting polythiophene is 255 S/cm under optimal conditions.
