| 20130052426 | THREE-DIMENSIONAL SHAPED NONWOVEN STRUCTURES FOR ACOUSTIC INSULATION AND PRODUCTION METHOD THEREOF - A three-dimensional (3D) nonwoven structure is provided having fibers oriented in different directions and superficial shapes in predefined areas. The structure comprises at least three layers, a top layer, a bottom nonwoven layer and a randomly oriented fiber layer, connected with fibers in predefined areas. The layers are connected using a special technique based on the needle board configuration of the needle-punching machine, and may be needled with different needle positions. A special needle loom feeding system to feed the different layers and to produce the product is also disclosed. | 02-28-2013 |

| 20100211253 | INTELLIGENT CONTINUOUS MONITORING SYSTEM FOR APPLICATION IN SHOCK ABSORBERS - The present invention relates to a continuous monitoring system for shock absorbers, for use in motor vehicles or in any kind of machine which requires them, which will enable the shock absorbers to be evaluated during normal operation. It is essentially characterised by all the necessary components being embedded into the shock absorber itself, in a single circuit | 08-19-2010 |
| 20110006194 | METHOD AND DEVICE FOR MEASURING SOLAR IRRADIANCE USING A PHOTOVOLTAIC PANEL - The present invention relates to a measurement method to determine the magnitude and intensity of solar radiation/collected by a photovoltaic solar panel, without the need of using specific sensors for this purpose—With the present method̂ the power conditioning systems used in small photovoltaic panels to charge small rechargeable batteries, will now be able to provide an electrical signal, in the form of a pulse sequence or in any other electrical signal, that represents the value of the quantity that generates the available energy. The present method enables the monitoring the energy transfer between the solar panel and a rechargeable battery using a switched, voltage converter; additionally it indicates the magnitude of the solar radiation falling on the solar panel. It is based on the adaptation of a direct voltage to direct voltage boost converter circuit in. order to provide an electrical signal which is correlated to the magnitude of the solar irradiance falling on the solar panel, which in turn powers the voltage converter circuit. The invention also relates to a device for implementing this method. | 01-13-2011 |
