20140196063 | METHOD FOR GENERATING A MENU FOR PRESENTING AUDIOVISUAL PROGRAMS PAID FOR BY SEVERAL USERS, DEVICE AND COMPUTER PROGRAM FOR IMPLEMENTING THE METHOD - A method is provided for generating a presentation menu for presenting audio and audiovisual contents on the screen of a receiver, which are downloadable from a broadcasting network or from dedicated sites. A user selects accessible contents and makes payment to make these contents available at the receiver. The receiver retrieves information on availability of all the contents from the receiver and requests display of a presentation menu presenting a list of available contents. Thus each user gets to know all the available contents from the receiver, including those purchased by other users. The presentation menu can visually associate each document with the identity of the user who made the document available. The presentation menu can display an indication that the replay of an available content has already begun and has been interrupted at a certain point in time. This point in time is made available at the display. | 07-10-2014 |

20080233893 | Wireless Tranceiver Configuration with Self-Calibration for Improved Out of Band Interferer Rejection - The present wireless transceiver includes a tuneable narrow band LNA which rejects dramatically any out of band interferers. The tuneable narrow band LNA may be operable over a wide frequency band. A loopback calibration procedure is used to control the tuneable narrow band LNA so as to produce a substantially flat gain characteristic over the band of interest. | 09-25-2008 |

20130084852 | 2G, 2.5G RF LOOPBACK ARRANGEMENT FOR MOBILE DEVICE SELF-TESTING - In a mobile communication device a loopback technique is used to enable the receive chain circuitry and digital baseband block to perform self tests on the transmit chain circuitry of the same mobile communication device for 2G and 2.5G operating Bands and channels. A transmit chain circuit is set to transmit a selected receive Band channel, which is attenuated via a loopback path within the mobile communication device's front end module and, in some embodiments, via a leakage signal path between adjacent or proximate LNA inputs of separate receive chain circuits. | 04-04-2013 |

20090130615 | Method for Calcination of a Material with Low NOchi Emissions - The invention relates to a method for calcination of a material in which said material is heated by contact with a heat source essentially generated by means of a flame produced with at least one flow of fuel and primary air and a flow of secondary air, the flame comprising a first combustion zone with a temperature below 1500° C. and a second combustion zone with a temperature above 1500° C., where at least one flow of at least one inert gas is injected into the flame at the beginning of the second combustion zone and/or at least one flow of oxygen or a gas enriched in oxygen is injected into the second combustion zone. | 05-21-2009 |
20100257899 | Oven and Oxy-Combustible Method for Melting Vitrifiable Materials - The invention relates to a method for melting vitrifiable materials in a low-capacity oven, wherein at least part of the melting energy is supplied by two oxy-burners projecting into the melting chamber through the upstream wall and arranged on opposite sides of a vertical plane in which a longitudinal axis of the melting chamber is situated, in such a way as to create two flames, the respective injection axes thereof crossing at a distance from the upstream wall, between ⅓ and ¾ of the length L of the melting chamber. | 10-14-2010 |
