University of Huelva posted this:NEW CONFIGURATIONS OF CC-CC CONVERTERS OF ONE INPUT AND MULTIPLE OUTPUTS WITHOUT TRANSFORMER AND POWER CONVERTER THAT APPLY THEMIt presents new configurations of CC-CC converters of single input and multiple outputs, without transformer, with a single input inductor. For its operation a single power switch is required, therefore, a single control circuit, which results in a smaller size, lower weight and simplicity compared to known systems
University of Huelva posted this:New method for manufacturing powder metallurgy magnetsThe conventional method of press followed by furnace sintering is now substituted by an electrical consolidation method. This allows joining in a single step the previous pressing/sintering processes, and, due to the promptness of the process, the use of controlled atmospheres is not necessary. The steps of magnetization, and eventual thermal treatments, can be carried out in the same container, without being necessary to manipulate the product.
University of Huelva posted this:New device and system for the recovery of communication equipmentThe present device is focused on the automatic recovery of operating systems for routers and switches, which is one of the fundamental claims on this invention since there are no current devices in the state-of-the-art for such purposes. Another particularity that distinguishes to the present invention is that it is not only software or hardware in contrast to other approaches, but of a complete hardware/software device (i.e, both capabilities are combined). Another of the most significant singularities is its portability, since the invention is based on a reduced size device (non rackable) and made up of autonomous battery. This allows to carry out any function with total freedom to move. Besides the comfort, it contributes a great improvement in working time, since operating with distant devices implies an additional time in turning off, turning on again, and enabling the necessary services to start the recovery procedure. As additional feature, the invention looks for the universality and independence from manufacturers or device model. Besides this purpose, another differentiated function is the capability to store the firmware of the communication devices to be recovered (i.e., the image of the operating system) through an internal physical storage unit of great capacity.

On the other hand, the innovation allows reusing the RJ plug as many times as required until properly assembling the copper pairs. Furthermore, the connector incorporates an identification by color codes for wiring according to the ANSI/TIA-968-A-2002 standard, which is ideal for people with limited dexterity on IT.

University of Vigo posted this:Suppression of Impulsive Noise for Power Line CommunicationsPower Line Communications (PLC) is an emerging field that enables to carry data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. The widespread use of these technologies is however, compromised by the presence of impulsive noise that arises from interferences generated by devices connected to the power line. Therefore removal of impulsive noise is critical to get a high performance of PLC systems. UVIGO researchers have developed a novel methodology to mitigate impulsive noise by monitoring those carriers of the radiofrequency spectrum that are free of transmission in PLC systems. The identification of the noise signals allows its selective removal keeping the quality of the overall PLC signal.
