20110305344 | METHOD AND APPARATUS FOR THREE-DIMENSIONAL ACOUSTIC FIELD ENCODING AND OPTIMAL RECONSTRUCTION - A method and apparatus to encode audio with spatial information in a manner that does not depend on the exhibition setup, and to decode and play out optimally for any given exhibition setup, maximizing the sweet-spot area, and including setups with loudspeakers at different heights, and headphones. The part of the audio that requires very precise localization is encoded into a set of mono tracks with associated directional parameters, whereas the remaining audio is encoded into a set of Ambisonics tracks of a chosen order and mixture. Upon specification of a given exhibition system, the exhibition-independent format is decoded adapting to the specified system, by using different decoding methods for each assigned group. | 12-15-2011 |
20150124973 | METHOD AND APPARATUS FOR LAYOUT AND FORMAT INDEPENDENT 3D AUDIO REPRODUCTION - A method for encoding audio signals, for later reproduction in arbitrary three-dimensional loudspeaker layouts, based on the generation of an intermediate channel-independent representation, which enables the creation, manipulation and reproduction of sounds with complex apparent size and shape, including multiple disconnected shapes. | 05-07-2015 |
20150215410 | GEO-Referencing Media Content - Geo origination data is generated for a geo-tagged media device of a user from measurements performed by sensors. The geo origination data is sent to a server system. At the server system, geo-tagged media content elements are selected based on the geo origination data. Further, based on the selected geo-tagged media content elements and the geo origination data, geo-referenced rendering data to be used for rendering media content from the selected geo-tagged media content elements perceivable to the user of the geo-tagged media device is generated. The geo-referenced rendering data can be streamed to the geo-tagged media device along with media content derived from the geo-tagged media content elements for rendering at the geo-tagged media device. | 07-30-2015 |

20090055030 | CONTROL OF ACTIVE POWER RESERVE IN A WIND-FARM - A method and system of active power reserve regulation in a wind farm with a communication network having a plurality of wind turbines that provide an active power reserve in order to support eventual power grid contingencies and to deliver an increase of power in case it is needed. | 02-26-2009 |
20090167095 | CONNECTION AND DISCONNECTION SEQUENCE FOR VARIABLE SPEED WIND TURBINE HAVING AN EXCITER MACHINE AND A POWER CONVERTER NOT CONNECTED TO THE GRID - A variable speed wind turbine having a doubly fed induction generator (DFIG), includes an exciter machine mechanically coupled to the DFIG and a power converter placed between a rotor of the DFIG and the exciter machine. Thus, the power converter is not directly connected to the grid avoiding the introduction of undesired harmonic distortion and achieving a better power quality fed into the utility grid. Moreover, the variable speed wind turbine includes a power control and a pitch regulation. | 07-02-2009 |
