Title: Efficient multiple input multiple output system for multi-path fading channels
Inventor: ZEIRA ARIELA
IPC: H04J99/00
Filed: 2002-11-27
Abstract: Data is transferred in a wireless communication system, such as a wireless spread spectrum communication system. Data is encoded to produce a plurality of data streams (Fig. 2). For each of a plurality of transmitting antennas (34), the data streams are used to produce a vector for transmission. Each transmission vector is transmitted by its transmitting antenna through a wireless air interface experiencing multipath. Multipath components from each transmitted transmission vector are received by a plurality of receiving antennas (36). The received multiplath components are equalized to recover the transmission vectors. The data is recovered from the recovered transmission vectors.

Title: Porosimetric device
Inventor: VOLFKOVICH YURY MIRONOVICH
IPC: G01N15/08
Filed: 2004-07-07
Abstract: A porosimetric device is disclosed for studies of physicochemical properties of materials, in particular for study of the pore structure. The device comprises a balance, a clamping device for keeping the standard and the porous sample(s) in contact (the standard and the porous sample(s) containing wetting liquid inside their pores), an automatic manipulator for moving the sample frames, several drying stations for drying a number of samples simultaneously, automatic flow-meter valves for the drying gas, electric and pneumatic drives for the manipulator and the valves. Each drying station is placed at sufficient distance from the balance thereby enabling heating of the samples without heating the balance. The drying process is carried out by gas, which is heated up in special heaters. The manipulator has two degrees of freedom. It can perform vertical movements for placing samples and standards on the balance as well as horizontal movement between the drying stations and the balance. The porosimeter includes a gripper for sample frames, vertical servo-drives for each drying station, which provide vertical positioning of the sample frames when gripped, and a cap or a cylinder closed from the top, which tightly covers each sample and standard before weighing, thereby essentially reducing the evaporation of measuring liquid or condensation of moisture within the sample pores.

Title: Polymeric micelle complexes of low molecular weight antitumor agents and styrene maleic acid copolymers
Inventor: MAEDA HIROSHI
IPC: A61K47/48
Filed: 2004-02-02
Abstract: A polymer type antitumor agent comprising a polymer micelle complex structure formed as a result of intermolecular boding or interaction between a low-molecular antitumor agent, such as an anthracycline antitumor agent (e.g., pirarubicin, doxorubicin, epirubicin, daunorubicin or aclarubicin), cisplatin or an alkaloid antitumor agent (e.g., taxol), and a styrene/maleic acid copolymer (SMA).

Title: Audio coding method and apparatus using harmonic extraction
Inventor: HA HO-JIN
IPC: G10L19/035
Filed: 2002-12-12
Abstract: A method and apparatus for effectively encoding an audio signal into a Moving Picture Experts Group (MPEG)-1 layer III audio signal of a low-speed bitrate.  In the audio encoding method, harmonic components are extracted using fast Fourier transformation (FFT) result information that is obtained by applying psycho-acoustic model 2 to received pulse code modulation (PCM) audio data.  Then, the extracted harmonic components are removed from the received PCM  audio data. Thereafter, the PCM audio data from which the extracted harmonic components are removed is subjected to a modified discrete cosine transform (MDCT) and quantization. Accordingly, efficient encoding can be achieved even using a small number of allocated bits.

Abstract: L'invention concerne des améliorations apportées à la mise en oeuvre d'une modulation en couches. La présente invention concerne deux mises en oeuvre de modulation en couches, l'une faisant appel à un transpondeur unique et l'autre faisant appel à de multiples transpondeurs par fréquence de signal, respectivement. La 8PSK hiérarchique en couches (H-8PSK) est un cas spécial de modulation en couches. Par précodage de la partie à priorité élevée (HP) d'un signal H-8PSK, la modulation en couches peut améliorer le rapport porteuse/bruit (C/N) d'un signal H-8PSK. La modulation en couches peut être simulée par ordinateur et un signal à deux couches peut être démodulé successivement à l'aide des performances de C/N prédites. Un signal de modulation en couches peut être simulé à l'aide de signaux en direct pour un traitement différé. De plus, un appareil de traitement des signaux peut traiter des signaux de modulation en couches émulés à partir de signaux transmis par satellite en direct.

Abstract: The thermoelastic response of certain materials to an incident electromagnet ic excitation beam is highly sensitive to physical conditions existing at the surface of the material. Probe structures carrying probe materials are used as sensors in the analysis and investigation of bio-chemical molecules. Each probe structure is adapted to undergo a thermoelastic response when excited by temporally varying electromagnetic radiation, characteristics of the thermoelastic response being a function of physical properties of material binding to the surface of the probe structure. An electromagnetic excitation means directs electromagnetic energy at a selected one of the probe structur es in order to elicit the excitation response. A detection means determines change in excitation response of the probe structures resulting from the binding of molecules thereto.

Abstract: Biomass, including waste biomass, is gasified by a process in which the biomass is first carbonized, and the char and pyrolysis gas from the carbonizer are respectively fed to a high temperature gasifying part and a gas reformer part of a two-stage gasifier. A gasifying agent is continuously fed to the gasifying part, and intermittently fed to the gas reformer, to maintain the temperature required to avoid tar formation in the gas reformer stage. Multiple carbonization chambers are operated in rotation. When the carbonization/gasification apparatus is used to provide fuel to an electric power generator set, exhaust heat from the generator power plant is fed back to the carbonizer, and can be supplemented by exchange of heat from the gas delivered to generator power plant from the outlet of the gasifier.
