University of Vigo posted this:New wheel slip reset controller for brake systemsThe main motivation for using reset control is the overcoming of fundamental limitations or trade-offs of conventional controllers: with the conventional controllers if we want a fast braking response, the system is fragile and sensitive to uncertainties; and if we want a robust system, this requires slower braking actions. Reset control is a novel technique that achieves more robust and fester braking responses in a way that no other conventional controller is able to produce.
University of Vigo posted this:New non-destructive method for “in situ” monitoring of anticorrosive protection of organic coatingsThe main novelty of the device and procedure is the new portable sensor adaptable to virtually any surface. The device, fixable by vacuum to the surface under study, makes possible the measurement of the electrochemical interfacial impedance, that is the main parameter of interest for adherence quality and anti-corrosion performance.
UATEC - Unidade de Transferência de Tecnologia posted this:Variable flow pump for longitudinal displacementA Portuguese University has developed an invention consisting of a new concept of flow variation in a vane pump that allows to bypass the concepts now patented and used. This invention therefore relates to a variable displacement vane pump and the variations in the fluid’s flow rate conveyed by the pump for a given rotation is achieved by changing a longitudinal length of the chambers, and not by changing the eccentricity between the ring and the rotor. This is the main difference between this and the variable flow vane pumps currently available. The university is looking for companies that develop and produce oil pumps to license this technology.

The invention consists of one or two cameras one settled up on the right lateral back and/or another one on the previous part. The system provides automatically an audible or visual alarm to inform the driver that some vehicles are approaching the exit lane. The group seeks automotive companies to achieve license, commercial or collaborative agreements with technical assistance.
UNIVERSIDAD DE ALICANTE posted this:Noble metal-free ceria-based diesel soot combustion catalyst, suitable for gas purification in Diesel engine exhaustsThe developed catalyst does not use Pt, which leads to a cheaper product. The resulting catalyst shows equal or even better performance as Pt catalysts. Following the patented procedure of synthesis, the catalyst produced has a lower particle size. This leads to higher surface per particle and therefore, a better ratio yield when interacting in oxidation reactions, leading to a higher oxygen production rate.
UNIVERSIDAD DE ALICANTE posted this:New process for the stereoselective synthesis of acetylenic compounds used as additives in galvanic bathsRegarding the existing state of the technique, the electrochemical processes have characteristics which make them very adequate to be applied for the synthesis of organic compounds with industrial application. Here, oxidation processes occurs upon electrodes named anodes where the substance which must be oxidized loses its electrons on the anode without needing conventional oxidising agents. Therefore, contaminants derived from the use of conventional oxidising agents are not generated and hence, no need for the management of hazardous residues is applicable. On the other hand, the electrochemical processes are developed under soft conditions (atmospheric pressure and room temperature) and clearly facilitate further processes of separation of one of the compounds of the reaction mixture.

It is a positioning system of high precision, possibilities of communication for long distance(movable telephony) and short distance (radio frequency). The detection of vehicles speeding depending on maximum authorized speed and the implementation of the idea of " pay as you drive " in order to invoice the vehicle assurance.
UNIVERSIDAD DE ALICANTE posted this:Energy absorbing device in motor vehicle collisionsResearchers at the University of Alicante have devised a system to partially absorb the energy generated in a crash involving at least one motor vehicle traveling at a high or medium speed. It is a passive protection system for vehicles which absorbs the maximum amount of mechanical energy in a crash with minimal added weight and volume. Assumes additional protection that enhances the vehicle's passive safety, minimizing the consequences of a collision for the passengers. The system has an innovative design that allows placing it in different positions inside the vehicle or making structural parts and is manufactured with advanced materials. Innovative aspects The system is designed to provide protection that goes beyond the current regulations for passenger cars, as it is able to absorb a larger proportion of the mechanical energy generated in a collision. Also improve the passive safety of vehicles (vans, trucks) or special vehicles (ambulances, fire trucks, armored vehicles) in circulation. It also provides substantial improvements for heavy duty vehicles, contrary to what is happening now should be able to absorb themselves much of the energy produced in a collision with a vehicle lighter, thereby minimizing the potential damage that may occur in people who travel light vehicle. The system consists in several stages which act consecutively on impact, absorbing energy in a gradual and proportional to the energy generated in the collision, which is a lower acceleration on passengers, thereby reducing the potential injuries. Less weight, volume and system size compared to traditional structural systems, through the use of advanced materials: tensile filaments that act in case of collision, thermosets broken links which act by absorbing the impact energy generated in the fiber and combined with high strength composite metal / polymer composite micro / nanostructures
