20120279549 | ORGANIC PHOTOVOLTAIC CELL AND MODULE COMPRISING SUCH A CELL - An organic photovoltaic cell comprising a substrate, a first electrode formed on the substrate, an organic photoactive medium comprising an electron donor and an electron acceptor, and a second electrode comprising a conductive mesh, the first electrode being located between the substrate and the second electrode. The cell comprises an insulating mesh formed on the first electrode. The conductive mesh is formed on the insulating mesh. The insulating mesh and the conductive mesh define together apertures for receiving the photoactive medium, said apertures being able to receive the photoactive medium after the first electrode, the insulating mesh and the conductive mesh have been deposited on the substrate. | 11-08-2012 |

20140124029 | CONDUCTING SUBSTRATE FOR A PHOTOVOLTAIC CELL - A conducting substrate includes a dielectric substrate having alkali ions, an electrode coating having a molybdenum-based layer on the substrate, and a stack of several layers between the substrate and the electrode coating. The stack comprises a first layer impermeable to alkali on the substrate, a layer for retention of alkali on the first layer impermeable to alkali and made of another material, and a second layer impermeable to alkali on the layer for retention of alkali and made of a material other than the layer for retention of alkali. The ratio of the thickness of the layer for retention of alkali to the first layer impermeable to alkali is equal to 2 or more. | 05-08-2014 |

20150097423 | ELECTRIC POWER SUPPLY NETWORK LINKED TO A TRANSPORT SYSTEM - An electric power supply network includes at least one connection point with an upstream electrical network delivering useful power to at least one input of a first electric power supply network of an electrically powered transport system, such as trolley buses, trams, metro, train, or other transport, the first electrical network presenting peak power fluctuations as a function of variable energy needs depending on traffic associated with the transport system. The first electrical network includes at least one power output capable of distributing energy, in particular recovered from the transport system and from the upstream electrical network, to at least a second electrical network, enabling energy to be supplied to electrical consumption points. At least one supervision unit monitors distribution of energy from the power output whenever at least the peak power required by the first transport system is below the useful power available upstream. | 04-09-2015 |

20100005290 | METHOD OF IDENTITY PROTECTION, CORRESPONDING DEVICES AND COMPUTER SOFTWARES - A method is provided for authenticating a client terminal with an authentication server. The client terminal holds an authentication certificate. The method includes the following phases: obtaining at least once encryption parameter by the client terminal; encrypting the authentication certificate by the client terminal, based on the at least one encryption parameter, delivering an encrypted authentication certificate; transmitting the encrypted authentication certificate to the server, obtaining the at least one encryption parameter by the server; obtaining the at east one encryption parameter by the server; decrypting the encrypted authentication certificate, based on the at least one encrypting parameter, authenticating and delivering an authentication assertion if the authentication is positive. | 01-07-2010 |
20120072994 | METHOD TO PRODUCE SECURING DATA, CORRESPONDING DEVICE AND COMPUTER PROGRAM - A method and apparatus are provided for generating security data for implementing a secure session between a first and at least a second entity according to a secure session establishment protocol. Such a method includes: initializing a third secure entity connected to the first entity; generating at least a portion of the security data within the third entity; transmitting the generated security data from the secure third entity to the first entity; and transmitting at least a portion of the security data generated in the third secure entity to at least a previously initialized fourth secure entity connected to the third secure entity. | 03-22-2012 |
