Abstract: La présente invention concerne des articles absorbants jetables dont la forme s'adapte automatiquement lors de l'utilisation, en particulier des serviettes hygiéniques ou des protège-slips. La présente invention concerne plus précisément les articles absorbants jetables qu'on fixe directement sur la peau de l'utilisateur, dans la zone où l'on souhaite l'absorption de liquides corporels, et qui, lors de l'utilisation, adaptent leur forme à la configuration tridimensionnelle négative de l'utilisateur. De tels articles doivent être fixés par adhésif topique de manière solide et procurer une sensation agréable, aussi bien lors de leur mise en place, que pendant leur utilisation, sans causer de gêne au moment de leur retrait. On obtient ces résultats, grâce à la présente invention, en sélectionnant les caractéristiques rhéologiques des adhésifs utilisés dans de tels articles.

Patent CA-2289903-A1 (CA)
Title: Vascular adhesion protein-1 having amine oxidase activity
Inventor: JALKANEN SIRPA
IPC: C12N15/09
Filed: 1998-05-22
Abstract: VAP-1 is an endothelial sialoglycoprotein whose cell surface expression is induced under inflammatory conditions. It has previously been shown to mediate the binding of recirculating lymphocytes to human peripheral lymph node vascular endothelial cells in an L-selectin independent fashion. A VAP-1 cDNA has been purified and shown to encode a type II transmembrane protein of 84.6 KD with a single transmembrane domain located at the very N-terminal end of the molecule. VAP-1 exists, in vivo, predominantly as a dimer of 170-180 KD. Six potential N-linked glycosylation sites are located in the extracellular domain, as are three putative O-glycosylation sites. VAP-1 has no significant similarity to any currently known adhesion molecules but has significant identity to the copper-containing amine oxidase family. Enzyme assays have defined VAP-1 as a membrane-bound amine oxidase. Thus, VAP-1 is a new type of adhesion molecule with dual functions. With the appropriate glycosylation, and in the correct inflammatory setting, VAP-1 expression on the lumenal endothelial cell surface in locations mediating lymphocyte adhesion allows it to function as an adhesion receptor involved in a novel mechanism of lymphocyte homing. Its primary function in other locations may depend on its inherent amine oxidase activity.

Patent CA-2308621-A1 (CA)
Title: Afc device and method of controlling reception frequency in a dual-mode terminal
Inventor: LEE HYUN-KYU
IPC: H03J7/02
Filed: 1999-09-02
Abstract: An AFC (Automatic Frequency Control) device and a method of controlling reception frequency in a dual-mode terminal. When a dual-mode terminal uses one or two AFC circuits, time required for acquiring tracking synchronization in a PLL circuit for a frequency can be reduced using a test augmentation frequency being an integer multiple of a tracking synchronization acquiring residual frequency of a PLL circuit for another frequency to which the first frequency transits for reliable synchronization acquisition. Errors with respect to an output dynamic range caused by use of two AFCs are reduced and thus the demodulation performance of a receiver is ensured by varying quantization bits of an A/D clock based on the dynamic range of residual errors in a frequency area. The demodulation performance can also be ensured by operating an ACPE circuit for an AFC circuit having many residual frequency errors. In this method, the frequency characteristics of the dual-mode terminal are stabilized and the stability of a demodulator is increased due to a frequency offset. As a result, the stable demodulator performance is ensured.

Patent CA-2314239-A1 (CA)
Inventor: ONIZAWA TAKESHI
IPC: H04L27/26
Filed: 2000-07-18
Abstract: A preamble for synchronization, or a reference timing for operation of an OFDM packet communication receiver system is detected finely even under environment of large waveform distortion due to thermal noise and/or multi-path propagation, and/or large carrier frequency offset between a transmit side and a receiver side. A correlator (1) detects a pattern of a short preamble (t1 - t10) in a preamble for synchronization. An output of the correlator (1) is applied to a complex filter (7) which separates a short preamble having a predetermined repetition period from uniformly distributed noise. A scalar filter (9) integrates some period of short preambles which have distributed-delay by multi-path propagation as if a single short preamble with no delay were received for determining a reference timing. When a correlator output exceeds a predetermined threshold level a plurality of times far every repetition periods (T) of a short preamble, and an output of the correlator after time (T) from the last short preamble is decreased a predetermined ratio as compared with that of the last short preamble, it is determined that a preamble for synchronization is detected. Carrier frequency offset compensation is carried out either for each short preamble during reception of a short preamble, or based upon the last received short preamble during reception of an OFDM symbol after the last short preamble. As a preamble for synchronization is detected accurately, a guard interval of each OFDM symbol is removed accurately, or an FFT window is defined accurately, so that a demodulation is possible in spite of noise and/or interference.
