University of Huelva posted this:Power supply system controlled from internet for devices connected to a lanNowadays there are devices that allow the control of devices connected to a network from the own network. The classical method to access them from a different network is the redirection of the corresponding TCP or UDP connections to local networks from the border router. The redirection requires a high level of expertise in communications to be performed. Another strategy that is often used is the creation of VPN (virtual private network). This technique allows the control of access but does not allow connections to be discriminated or the management of power supply. The proposed system allows you to control the person and the moment to access as well as the free access. The modification of these constrains can be performed in the course of an access session. In addition, the system allows the control of power supply of the device you want access to. The interface is very friendly and does not require continuous changes in the configuration of the router. The system has a local database access control and validation can be delegated to other servers using protocol validation like LDAP, IMAP, POP3, etc.

University of Huelva posted this:DC-DC CONVERTER WITH BIPOLAR OUTPUT AND ITS USE FOR CONNECTION OF A DISTRIBUTED GENERATION SYSTEM TO A BIPOLAR DC GRIDThe converter has an input for connecting a monopolar DC source and a bipolar DC output, with the same voltage but with opposite polarities. It is useful for the connection of a distributed generation system to a bipolar DC grid. For these applications, the proposed topology is a solution with sufficient guarantees of reliability, quality and performance. The converter circuit is very simple, it includes three inductors, four capacitors, two diodes and a power switch as a switching device.

Universidad de Alcalá-OTRI posted this:Risk management of the effects of solar activity: Device and procedure of obtaining in real time and high resolution, the Local Geomagnetic Disturbance at middle latitudes.The research team specialized in Space Meteorology within the Space Research Group of the University of Alcalá, has developed a device and procedure that, based on the measurement of the local geomagnetic field, is able to estimate the magnetic disturbance component associated to solar activity at middle latitudes. The determination of the magnetic disturbance component is especially relevant in cases of sporadic but explosive solar phenomena. From the perspective of the actual user, the present invention constitutes an essential element in the risk management of the effects of solar activity on vulnerable technologies, both ground-based and satellite-based (electric power, rail transport, terrestrial and positioning navigation systems, radio and satellite communication systems ...), increasing the capacities of public administrations, civil protection and emergencies and the companies themselves, in order to prepare a successful strategy for adverse conditions related to the solar activity. The group is looking for collaboration and/or commercial agreements with the Central Administration, Civil Protection, Critical Infrastructure, Electric Power companies, Rail Network, Oil pipelines companies, Gas Pipelines companies, Insurance firms, etc...
UATEC - Unidade de Transferência de Tecnologia posted this:Emulsified suspensions for cold accumulationA group of researchers from a Portuguese University developed a phase change composite material with high thermal conductivity, dispersed in an aqueous matrix with self-organization, processable in situ and with high potential for use in cold storage systems. The new material allows to accumulate a large amount of energy in the form of latent heat, the thermal conductivity is improved and, mainly, it eliminates the stability problems of the devices incorporating the material due to the small volume variations in the phase shift. The university is looking for companies in the field of cold storage systems, to assess the potential integration of this technology in existing commercial equipment and license the technology.

The process uses electrospraying technique to deposit a suspension of a carbon material over a collector. This method facilitates processing superporous nanostructured carbon materials due to its high efficiency and less complexities compared to conventional techniques. The electrodes obtained can be used in energy storage or analytical sensors in commercial devices.

New designs are enabled since this "Liquid-Carrier for Hydrogen" is stored in tanks of any shape. The economics of this system have been validated by DOE and is among the least expensive methods of high-volume hydrogen storage. When loaded with hydrogen from renewable sources this technology delivers a complete green solution since the carbon portions of the molecules are completely re-used. With a well-to-wheels efficiency comparable to gasoline or EVs, this technology can deliver world-class efficiency.
