One aspect of the present invention is a frequency conversion circuit having a pair of local oscillators. The local oscillators are frequency synthesizers based on an external frequency reference. The frequency conversion circuit is configured to perform a frequency conversion to an inp ut signal equal to a frequency difference of signals from the pair of local oscillators; to generate an oscillat...

The present invention relates to a coupling node (MG 1 ) for coupling of communications in a telecommunication system, comprising networks (N 1, N 2 ) with different signal formats. The coupling node has switching and trunking functions (CP 21, CP 23 ) corresponding to the signal formats, and telefunctions, e.g. coders/decoders (F 21 ) and echo cancellers (F 22 ), which the node can couple into a ...

L'invention concerne un procédé de production d'essence à faible teneur en soufre comprenant au moins trois étapes : une première étape dans laquelle les composés soufrés présents dans l'essence sont au moins partiellement transformés en H 2S et en composés soufrés saturés, une deuxième étape visant à éliminer l'H2S de l'essence produite dans la première étape et une troisième étape dans laquel le...

An approach for allocating system capacity of a communication switching syst em for exchange of traffic is disclosed. The system includes multiple terminals tha t request allocations of system capacity. The capacity is partitioned into a provision ed portion and an unprovisioned portion, in which a portion of the terminals constitutes a poo l having a plurality of sub-pools. According to one embod...

A set of adapted digital ventilation and perfusion images is generated by adapting the images to each other based on contours (11) in these images. These contours are derived from intensities in the images. Independent claims are also included for (a) a memory medium used to carry out this method, which can be read by a computer or stored on a computer program, and (b) an image processing device ...

The invention is especially directed to a system for purifying exhaust gases of diesel or gasoline engines containing on average an excess of oxygen, this system including three operational units being an oxidation catalyst (3), a particle separator (4), and an NOx adsorption catalyst (5), this system reducing the amount of hydrocarbons, carbon monoxide, nitrogen oxides and particles present in ex...

A spill containment apron is made of a fluid-impervious sheet that forms a receptacle from which side flaps and end flaps extend. A plurality of straps having hook and loop fasteners at each end are passed under the sheet and extend on either side thereof. A plurality of magnets are included as part of the side flaps and end flaps. A drain valve is provided for the bottom of the receptacle. A p...
