| 20120027050 | METHOD AND DEVICE FOR GENERATING ULTRA WIDE BAND PULSES - The disclosure relates to a method for generating UWB waveforms, each comprising a sequence of pulses, the method comprising: generating consecutive elementary pulses having durations corresponding to setpoint durations and a constant amplitude, amplifying each elementary pulse separately as a function of a respective setpoint amplitude, and combining the amplified elementary pulses to obtain a waveform successively comprising each of the amplified alternately positive and negative, elementary pulses. | 02-02-2012 |
| 20110148677 | D-CLASS DIGITAL AMPLIFIER CONFIGURED FOR SHAPING NON-IDEALITIES OF AN OUTPUT SIGNAL - The disclosure relates to an amplifier comprising a digital delta-sigma modulator, a quantifier receiving a signal supplied by a delta-sigma stage and supplying a quantified signal, and a power circuit supplying an output signal. The device comprises N state loops of a first type configured to send the output signal to adders of N delta-sigma stages of lower rank, each state loop of the first type comprising an analog low-pass filter for supplying a filtered output signal, and an analog to digital converter for supplying a digital filtered output signal. | 06-23-2011 |
| 20100105106 | PREPARATION AND USES OF GENE SEQUENCES ENCODING CHIMERICAL GLYCOSYLTRANSFERASES WITH OPTIMIZED GLYCOSYLATION ACTIVITY - The present invention relates to the production of gene sequences encoding chimerical membrane glycosyltransferases presenting an optimized glycosylation activity in cells transformed with said sequences, said gene sequences corresponding to the fusion: of a first nucleic acid coding for a C-terminal minimal fragment of the catalytic domain (CD) of the native full length glycosyltransferase, to a second nucleic acid coding for a transmembrane peptide comprising in its N-terminal region a cytoplasmic tail (CT) region located upstream from a transmembrane domain (TMD), itself located upstream of a stem region (SR), provided that at least one of these CT, TMD, SR peptides being different from the primary structure of the naturally occurring peptide counterparts present in the native glycosyltransferase from which is derived the CD fragment with optimal glycosyltransferase activity as defined above. The invention also relates to the use of said gene sequences in the frame of the preparation of recombinant proteins of interest by cells transformed with said sequences and sequences encoding said recombinant proteins. | 04-29-2010 |
| 20100034000 | ELECTRONIC CIRCUIT HAVING A DIODE-CONNECTED MOS TRANSISTOR WITH AN IMPROVED EFFICIENCY - An integrated circuit including a semiconductor layer; and a MOS transistor including first and second power terminals and a bulk insulated from the semiconductor layer, the first power terminal being intended to receive an oscillating signal, the transistor gate and the bulk being connected to the first power terminal. | 02-11-2010 |
| 20090010321 | METHOD AND DEVICE FOR PROCESSING A PULSE TRAIN OF A MODULATED SIGNAL, IN PARTICULAR AN ULTRA WIDEBAND SIGNAL MODULATED BY A DIGITAL PULSE INTERVAL MODULATION - The pulse train of a signal is modulated by a DPIM modulation involving a discrete random time parameter. A first processing is performed on the signal to deliver a sampled signal. A second processing is performed on the sampled signal, comprising a correlation processing including at least one elementary correlation processing with a correlation mask corresponding to the shape of at least part of a sampled pulse, and delivering second information items. A third processing is performed for detecting the pulses following a first pulse by taking account of the position of the first pulse, on packets of second information items, which are separated by a duration related to the discrete random parameter. | 01-08-2009 |
