20130272152 | METHOD FOR TESTING AN AMPLIFICATION PATH FOR TELECOMMUNICATIONS SATELLITE REPEATER - A method for testing an amplification path of a repeater for a satellite for broadcasting the usable signals, the amplification path making it possible to frequency amplify usable signals from a plurality of communications channels, the channels being situated in a first frequency band, the amplification path being adapted to the first band, wherein the satellite includes a signal generator of a subsystem that enables generation of telemetry data to a second transmission antenna for reception thereof on Earth, the method including defining a test signal that includes the selection of a carrier frequency situated in the first frequency band; configuring the repeater to enable transmission of the signal generated by the signal generator to the amplification path; switching of the test signal amplified via the amplification path to the second transmitting antenna. | 10-17-2013 |
20140119409 | METHOD FOR LOCATING A TERMINAL AT THE SURFACE OF A COVERAGE AREA BY MEANS OF A TELECOMMUNICATION NETWORK USING A MULTI-BEAM SATELLITE - A method for locating a terminal in a coverage area using a telecommunication network, the network including a multi-beam satellite, the area including various cells, each associated with a beam for linking to the satellite to which a frequency band is assigned, the method including: performing the uplink transmission of a message incorporated into a modulated signal to the satellite at a frequency shared by three different uplink beams such that the message is received by the satellite with three different amplitudes; performing the downlink transmission of three modulated signals incorporating the message, the first, second, and third signals each corresponding to a different beam from among the three beams; receiving the first, second, and third signals; determining the amplitudes of the message within the first, second and third signals; and determining the location of the terminal from the amplitudes of the message within the first, second, and third signals. | 05-01-2014 |
20140145877 | METHOD OF GEO LOCALIZATION OF A TERMINAL SENDING A SINGLE SIGNAL TO A SATELLITE SYSTEM - A method for localizing a terminal includes transmitting the signal by the terminal; receiving the signal by a first and a second satellite; transmitting the signal from each satellite to a receiving station; demodulating the signal received by the first satellite to determine a signal content and the time of arrival of the signal transmitted by the terminal at the receiving station via the first satellite; determining the time of arrival of the signal transmitted by the terminal at the receiving station via the first and second satellite; determining a position for the terminal by triangulation. | 05-29-2014 |
20140266881 | DATA COLLECTION DEVICE AND METHOD FOR THE LOCALISATION OF A SOURCE OF INTERFERENCE - A data collection device carried on board a satellite and making it possible to localise a source of interference, without using neighbouring satellites, comprises: a reception device able to receive the frequency on the ground of the interference; at least three antenna points arranged on the satellite so as to be able to receive a radiofrequency signal coming from the target surface; a processor able to determine the amplitude of the interference signal at the level of each of the antenna points; a connection device able to connect successively each of the antenna points to the processor. | 09-18-2014 |

20090087907 | Compositions and Methods for Growth of Pluripotent Cells - A method of propagating embryonic stem (ES) cells in an undifferentiated state, while maintaining both the pluripotency and the cells normal genotype is disclosed. The method comprises using recombinantly produced protein domains to attach human embryonic stem cells to the surface of a bioreactor. The ES cells are supplied with nutrients while they held in place by the recombinantly produced protein domains which may be chosen from Laminin G domain, Fibronectin domain 2, Fibronectin domain 3, Nidogen G2 domain, Nidogen G3 domain, Vitronectin somatomedin B domain, and Vitronectin somatomedin C terminal domain. Useful molecules are characterized by a high binding affinity for hES cells and a molecular weight of about 50 kDa±20%. | 04-02-2009 |

20090075373 | Neural progenitor cells derived from embryonic stem cells - The present invention relates to undifferentiated human embryonic stem cells, methods of cultivation and propagation and production of differentiated cells. In particular it relates to the production of human ES cells capable of yielding somatic differentiated cells in vitro, as well as committed progenitor cells such as neural progenitor cells capable of giving rise to mature somatic cells including neural cells and/or glial cells and uses thereof. | 03-19-2009 |
20090258421 | EMBRYONIC STEM CELLS AND NEURAL PROGENITOR CELLS DERIVED THEREFROM - The present invention provides undifferentiated human embryonic stem cells, methods of cultivation and propagation and production of differentiated cells. In particular it relates to the production of human ES cells capable of yielding somatic differentiated cells in vitro, and committed progenitor cells such as neural progenitor cells capable of giving rise to mature somatic cells including neural cells and/or glial cells and uses thereof. The invention also provides methods that generate in vitro and in vivo models of controlled differentiation of ES cells towards the neural lineage. The model, and the cells that are generated along the pathway of neural differentiation may be used for the study of the cellular and molecular biology of human neural development, for the discovery of genes, growth factors, and differentiation factors that play a role in neural differentiation and regeneration, for drug discovery and for the development of screening assays for teratogenic, toxic and neuroprotective effects. | 10-15-2009 |
