Abstract: This invention refers to a bandwidth optimiser, dynamically operating in connections relating to radio-communications for multi-bearer systems, especially useful for DECT systems for the short-distance transfer of data packets. Such an optimiser comprises: a first block to which bit error rate (BER) is fed and which calculates the most likely number (k) of retransmissions, which is required by the quality of air interface; a second block, which receives from the first one said number (k) of retransmissions and provides, on the basis of such a number, a table giving the change in transmission time with the number of bearers; and a third block, which is fed by the second one and decides the optimal number of bearers to be allocated to the connection and the output of which feeds a device for resources allocation (RA), said optimal number of bearers representing the maximum band to allocate to the connection, depending also on the traffic intensity.

Abstract: Unidad frontal para un aparato electrónico, especialmente una radio de automóvil, en la que la unidad frontal comprende: una caperuza frontal (10); unos elementos de control móviles (20), que están conectados en cada caso a través de una membrana (30) integralmente con la caperuza frontal (10), de manera que la membrana (30) sirve, durante un movimiento del elemento de control (20) como guía y como elemento de recuperación, caracterizada porque la caperuza frontal (10), los elementos de control (20) y la membrana (30) están fabricados a través de un procedimiento de fundición por inyección de dos componentes, de tal forma que la caperuza frontal (109 y los elementos de control (20) están fabricados de un policarbonato y la membrana (30) de un elastómero.
