Abstract: This permits the transmission of signals over the electricity network in such a way that the spectral density of power is adjusted to the regulations in the current rules by means of the possibility of introducing notches in transmission in an efficient manner. It is characterised by the adjustment of the power in one or more carriers of an OFDM signal for generating these notches, through the use of IDFTs of at least 1024 points (if the IDFT is complex) or at least 2048 points (if the IDFT is real) and through the use of a window to multiply the symbols to be transmitted in time.

Abstract: The invention relates to a blade for a horizontal-axis wind generator consisting of two flattened bodies which are arranged opposite one another in longitudinal convergence towards the tip without making contact with one another, said bodies being attached by means of an intermediate latticework formed by ties (3) with an aerodynamic profile, which ties are joined to the flattened bodies by means of hinged attachments providing flexibility to the structural assembly for preventing fatigue fractures.

Abstract: This process applies to a number of user kits (A, B, . . . X) and a head-end kit (1) communicating over the electricity network (2) using an upstream channel and a downstream channel. In essence, the process comprises accessing by multiple user kits (A, B, . . . X) in the upstream channel and the sending of multiple information frames by the head-end (1) in the downstream channel simultaneously applying OFDMA/TDMA/CDMA multiplexing and dynamically assigning each carrier so as to maximize transmission capacity in both the upstream and downstream channels. In turn, the process allows the adjustment of the quality of service according to the type of information and the user that requires the transmission and the dynamic allocation of bandwidth through constantly calculating the signal-to-noise ratio.

Abstract: A spring mattress that uses a multiplicity of elastic springs, spatially distributed according to a predetermined pattern, with highly variable configurations, obtained by shaping through cutting and pouring operations on a starting slab of foam material of a proper thickness. The resulting configuration that is adopted determines incoming portions in the spring elements that affect one or more of its sides, with variable magnitudes and depths, and outcropping portions from one or more of its sides, with a thickness and projection range that are also variable. The springs that make up the mattress are integrated on their lower end to the remaining continuous laminar portion of the original slab, and in a second alternate version, can be joined on their other end to a continuous laminar slab to which they are bonded by means of adhesion or similar operation.

Abstract: Applicable to two-way communication over the electricity network between a plurality of user equipments (2) and a head-end equipment (1); characterized in that the receptors in the equipment (1, 2) continually monitor communication quality by estimating signal to noise ratio (S/N) in the individual carriers in the upstream and downstream channels. The user equipments monitor the state of the network at each moment in time independent of whether or not the transmission is destination for them. Optimum transmission mode is chosen as a result of this monitoring by means of modifying, packet by packet, the number of bits per carrier, the redundancy introduced by a FEC generator (forward error correction/detection), the FEC code, and/or the transmission mode; so as to achieve optimum sharing of the network in time and frequency at all times and to maximize the transmission capacity of the various user equipments by the network.
