Title: Single-channel and multichannel coherent demodulation devices with no controller, and corresponding reception set with several paths of variety
Inventor: ROUX PIERRE
IPC: H04B1/707
Filed: 1998-08-06
Abstract: The invention relates to (single-channel and multichannel) coherent demodulation devices. According to the invention, coherent demodulation is effected with no knowledge of the signal transmitted (i.e., with no controller). The phase change is estimated by producing through application of a predetermined function a signed value from the argument of a sum signal, the said sum signal itself being obtained based on the signal received (by quadrature demodulation, complex despreading and summing on N samples). Estimation of the phase change is used in a phase servo loop, such that the system tends toward nil error. Means are provided to eliminate phase residual static ambiguity introduced by the application of the predetermined function. The invention also proposes using a plurality of such (single-channel and multichannel) coherent demodulation devices in a reception set with several paths of variety.

Abstract: A novel member of the synuclein family has been identified and is termed persyn.  The full amino acid sequence for the mouse and human isoforms are given in SEQ ID Nos 2 and 4, with the respective nucleotide coding sequences being given as SEQ ID Nos 1 and 3. The unusual expression pattern noted for persyn, in neurons and in skin, led to the realisation that synucleins affect intracellular intermediate filament structure.  Thus, an assay for cells exhibiting abnormal intermediate filament structure is described, based upon evaluation of intracellular synuclein.  The assay is special relevance to neurodegenerative disorders characterised by plaque deposition, to cancers (especially breast cancer) and to skin disorders.  An assay for screening agents of potential therapeutic value is also described.

Patent CA-2252651-A1 (CA)
Inventor: OSTENDORF WARD WILLIAM
IPC: D21H27/02
Filed: 1997-04-25
Abstract: An apparatus (10) for making paper. The apparatus (10) comprises a felt (14) and a pattern layer (18) joined to the felt (14). The felt (14) has a relatively high UV absorbance. Such a high UV absorbance prevents the actinic radiation applied to cure the pattern layer (18) from scattering when the radiation penetrates the surface of the pattern layer (18). By limiting the scattering of radiation beneath the surface of the pattern layer (18), extraneous cured pattern layer material is minimized in the regions of the felt (14) where it is desired not to have pattern layer material.

Abstract: A method and a system for operating a revolving credit program utilizing a table of tiered interest rates in which one of the interest rates is applied as a finance charge to a remaining outstanding balance (20) of an account depending upon the percentage that payments made during a billing cycle (12) comprise of an account parameter, such as the outstanding balance, a highest balance or a beginning balance. In the preferred embodiment the applied interest rate (34) is determined by the percentage the outstanding balance (32) is reduced by payments on the balance during a billing cycle. Also in a preferred embodiment of the invention, the tiered interest rate table is structured to apply progressively reduced interest rates to outstanding balances reduced by progressively greater payment percentages from the previous billing cycle, thereby encouraging a credit customer to make larger payments and pay down the outstanding balance faster. Also in the preferred embodiment, the system calculates and displays (42) the minimum payments necessary to reduce the outstanding balance to meet each tier of the interest rate table.
