Filed: 2001-08-17
Abstract: L'invention concerne un système pour une boucle de rétroaction de régulation de puissance fermée, qui permet l'utilisation d'un amplificateur non linéaire pour amplifier un signal à modulation de phase (PM) alors qu'est introduite une version inverse du signal à modulation d'amplitude (AM) désiré dans la boucle de rétroaction au moyen d'un élément de gain variable. Par introduction d'une version inverse de la partie AM désirée du signal dans la boucle de rétroaction de régulation de puissance, l'amplificateur de puissance non linéaire hautement efficace peut être utilisé pour amplifier uniquement la partie PM du signal, alors que la partie AM est introduite par la boucle de rétroaction de régulation de puissance. Dans un autre aspect de cette invention, une version inverse de la partie AM du signal de transmission désiré est introduite dans la boucle de rétroaction de régulation de puissance d'un amplificateur qui amplifie à la fois un signal à modulation de phase et un signal à modulation d'amplitude. Par introduction d'une version inverse du signal AM désiré dans la boucle de rétroaction de régulation de puissance, cette boucle de rétroaction de régulation de puissance peut ne pas annuler le constituant AM présent à la sortie de l'amplificateur de puissance. Dans un autre aspect de l'invention encore, le signal AM désiré est injecté dans la boucle de rétroaction avec le signal de référence de régulation de puissance.

Title: Turbojet automobile and aircraft propulsion system
Inventor: POHANKA MIKULAS
IPC: F02K1/78
Filed: 2003-05-27
Abstract: The contemporary Turbojet, used to propel aircraft is a good engine; but all of the Kinetic Energy of the outgoing gas is lost; I propose to fix a divergent nozzle on the end of its exhaust pipe; which functions as a diffuser of such shape and length that the gas slows its speed within it (to the back) to the same speed as is the forward speed of the aircraft or automobile;  shockwaves would then not form in the diffuser, therefore the pressure of the outgoing gas would be the same as is the pressure of the ambient atmospheric pressure: all of the Kinetic Energy of the gas is used to propel the aircraft; the gas exits the diffuser (without noise) with zero speed measured according to the surface of the Earth; then the theoretical propulsion efficiency of the Turbojet is 100%.
Patent CA-2433337-A1 (CA)
Title: Compositions containing optical diffusing pigments
Inventor: COHEN ISAAC D
IPC: A61Q19/00
Filed: 2001-12-20
Abstract: The present invention provides a method of preventing the appearance of fine lines, wrinkles and discoloration on the skin. This is achieved by the topical application to the skin of a composition containing a first platelet of alumina treated with a metal oxide, a second platelet treated with a spherical scattering component, and a cosmetic or pharmaceutical carrier. The compositions can also contain a standard interference pigment, such as a white and a yellow interference pigment to further blend the color to closely match the natural skin tone. The combination of pigments and platelets creates a mosaic of color and optically manipulates light such that lines, wrinkles, disfigurations and discolorations on the skin appear to substantially vanish.  In addition to the pigments and platelet components, a non-interference pigment can also be added to fine-tune the matching of color to the skin tone.  The alumina platelet alone is metallic-looking; however, when it is tempered with the other platelet containing the spherical scattering component, the net effect is that the skin appears natural, luminous and flawless.

Les murets sont constitués d'un sandwich de planches et de matériau isolant résistant en compression et poreux. Les planches sont de contreplaqué ou de OSB et ont la caractéristique d'être coupe-vapeur. Les murets ne dégagent pas de gaz toxiques s'ils sont exposés à la flamme. Une variante du muret est l'isolant à muret : un sandwich semblable destiné à être installé sur un muret existant. Si l'on installe les murets sur tout le pourtour de la fondation, on obtient la ceinture à poutrelle.

Title: Adjustable dispersion compensator with few mode fibers and switchable mode converters
Inventor: RAMACHANDRAN SIDDHARTH
IPC: H04B10/18
Filed: 2003-08-19
Abstract: The specification describes dispersion compensators that are adjustable based on selection of mode propagation properties of two or more modes. The fundamental device structure comprises two or more sections of optical fiber that support the fundamental mode as well as well as one or more higher-order-modes (HOM). The HOM fibers are connected to each other by means of a spatial mode-converter (MC) that is switchable. The MC may be fabricated with, for example, long-period fiber-gratings (LPG), coupled waveguide devices, free-space phase-retardation elements, micro-electro-mechanical devices, or acousto-optic couplers. The MC is assembled such that it transforms any incoming spatial mode into one of any other guided modes in the HOM fiber. Switching is achieved by strain, temperature, the electro-optic or nonlinear optic effect, or any other physical effect that changes the refractive index of the optical material used to construct the MC.

Inventor: KUO CHUN-MING
IPC: H02J9/06
Filed: 2003-10-31
Abstract: A household emergency power generator is described. The generator set uses gas as the fuel. Accordingly, the gas fuel can be supplied to the generator set through the general gas supply pipeline, therefore the disadvantages of storing oil fuel and the risk thereof can be effectively eliminated. The generator set is equipped with an automatic transfer switch (ATS). When the general power cut occurs, the ATS  automatically supplies gas to the generator set to set it into an operation mode to generate power for supplying to the power supply circuit, and when the general power is restored, the ATS cuts the gas supply to stop the generator set. Thus, the power supply to the power supply circuit remains uninterrupted.

Title: Method for protected transmission of data in particular for transmission via an air interface
Inventor: CUYLEN MICHAEL
IPC: H04L1/00
Filed: 2003-03-17
Abstract: The invention relates to a method for the secure transfer of data (D0-D4) whose coding ('S','0'-'F') is represented by a sequence (FR0-FR4) of a predefinable number of on and off values (Z1,Z0), whereupon a count value (C ) representing the predefinable number is formed, the direction of counting (F,R) is altered after each on value and the count value is incremented or decremented, and error information (F1,F2) is produced if a first end value (EC), which is transferred with the data as a coded sequence (SIG) of the count value C, is different from a second end value (EC1,EC2) which is forme d like the count value from the transferred sequence. The method can be used advantageously in identification systems (IS), mobile data carriers (DT) and write/read devices (SLG). One advantage of the invention is that a data transfer error can be recognized both quickly and with a high degree of certainty by using a simple up and down counter (CNT). The counter can be embodied in the form of a simple software program or an electronic circuit, i.e. a cyclic counter, requiring only a small amount of circuit technology f or the manufacture thereof.
