Abstract: A wind motor includes a post (1) tower or other supporting structure, a bottom base (2) that supports at least one pair of shafts (4, 5), at least one rotor (6) on each of the shafts (4, 5), a mechanism for synchronizing the rotation of the rotors (6), a front shield (7) secured to the bottom base (2), an arrangement for the free rotation of the bottom base (2) with respect to the post (1), tower or supporting structure, at least one electric generator or another device for converting mechanical energy, driven by one of the rotor shafts (4, 5) or by the synchronizing mechanism, and an inertial body driven by the energy provided by the rotors.

Abstract: The invention relates to calculation expression management. In general terms, a calculation expression is a union of variables, constants, operators functions, delimiter characters and other possible elements, which can be used to product a result. A sample calculation expression is as follows: “2*3+A*(2+B+C)”. The uses of calculation expressions include the creation of formulae, the formation of strings and the implementation of searches for databases. The invention facilitates the implementation of sophisticated calculation expressions. For said purpose, the invention consists in constructing and evaluating calculation expressions from graphical structures representing trees. The graphical structure scan be of various different types.

Abstract: The present invention provides assistance for a person to better comprehend the samples of a target language and, simultaneously, it facilitates that the person learns that language better. In order to do that, some special perspectives on those language samples are provided, and those perspectives show in a simple form the internal structure of said samples. All this will facilitate the person the assimilation of the structure and meaning of those language samples. The invention is based on two facts. First, linguistic research has show that language comprehension depends on the assimilation of the internal structure of the messages that are received. Second, language learning require the learner to comprehend messages of that language in order to be able to develop the competence to associate meaning and form.

Abstract: The invention relates to a system, method, computer program and data set which are intended to facilitate language comprehension and/or learning. For said purpose, samples of a target language are worked on and modified versions of said samples are used. The purpose of the modified versions is to provide clues which will enable the person using the invention to understand the target language samples. The invention greatly facilitates the management of the modified versions. In particular, the invention aids the tutor in the creation of modified versions and, in addition, in the identification of the versions most suited to the person interested in understanding and/or learning the target language. The modified versions are produced using sets of modifications, referred to herein as Relations, which are processed autonomously.

Abstract: The invention is intended to facilitate language learning by improving sound identification and perception. It is well known that foreign language students in particular have great difficulty in mastering the sounds of the foreign language being learned. Among other possible causes, this is due to interferences that occur between the written form of the target language and the sounds that the students associates mentally with used in the written form. In the case of foreign language learning, the aforementioned association comes fundamentally from the native language of the learner. The invention relates to a training method for learning languages involving the use of graphic entities which enable the sounds of the target language to be manipulated without creating interferences between the writ en and spoken form.

Abstract: This invention presents a system for adding unevenness to keyboards in touch screens. Said unevenness will help the user to better perceive the keys on which she is placing her fingers, therefore helping her to type faster and with higher confidence and accuracy. There exist several ways to add said unevenness. In one of them, a thin sheet is placed upon the touch screen, said sheet comprising several openings or cavities. When the user moves her finger over said openings, she will, by her sense of touch, perceive the keys on which her finger is moving. The previous sheet can be transparent to allow seeing the keys located on the screen, but it can also be opaque if the keys are printed on top of it in corresponding position to the keys that are shown on the touch screen.

Abstract: The present invention provides assistance for a person to better comprehend the samples of a target language and, simultaneously, it facilitates that the person learns that language better. In order to do that, some modified versions of those language samples are provided to the learner, in such a way that they allow the learner to comprehend the structure of said language samples, which allows to comprehend the meaning. Said modified versions are created by replacing some groups of words by some groups of characters which are called replacing words. Said replacing words allow to summarize subordinate clauses in the language sample, thus simplifying the complexity of the language sample. This allows the learner to focus on one idea at a time, and thus gradually build her comprehension of the language sample.

Abstract: The present invention facilitates the remote utilization of computerized systems, such as for example a computer that is connected to a television. This is the case, for example, of computers that are connected to a television in the living room. In this case, the current remote control units have several problems for text entering, mainly that the user needs to change her sight from close to far to close again. The invention is based on two aspects. On the one hand, showing a keyboard on the screen, and on the other hand using a remote control that comprises a touch surface which allows to show on the screen the position of the user's fingers. In so doing, the user can utilize the remote control simple looking at the television, because at all times she Hill be able to see where the fingers are located and on what key they are positioned.

Abstract: The invention relates to an organizer for complex categorizations. The development of computer science in general and the Internet in particular has led to an ever-increasing amount of information being made available to a large number of people, many of whom are not computer experts. As a result, new and improved mechanisms are required in order to organize said information and facilitate searches. The invention relates specifically to a type of organization for sets of entities, such as for example, objects, concepts, ideas, terms or other entities, which facilitates the conceptualization of classifications and the implementation of searches. In particular, the invention facilitates the formation of systematic categorizations which contain different criteria for organizing information, as well as facilitating the checking and use thereof by the user.

Abstract: The invention is intended to facilitate language learning by facilitating the learning of phonology and phonetics in general and, in particular, prosody. For said purpose, the pupil is trained to better perceive the rhythm and metric structure of the target language. The aforementioned training consists in listening to determined auditory playbacks using facilitating means which enable the pupil to better identify the prosodic features of the target language, and to develop his/her capacity to identify same.
