    摘要: A terminal for a communications network assembly comprises an antenna (22) which is operable in a first mode as a scanning antenna to scan electrically or mechanically and thereby determine a communications link with a selected one of a plurality of base stations, and in a second mode is operable as a communications antenna to communicate with the selected one of the plurality of base stations. Control means are provided which are operable to receive data from the antenna when operating in a scanning mode, to determine which base station should be used for future data communication, and can move the orientation of the antenna such that it is operable to communicate with the selected one of the base stations. Separate scanning and communication antennas may be provided.

    摘要: A direction adjusting display utilized when the direction of a satellite signal receiving antenna is adjusted. The direction of an antenna is determined watching the display on a display so that the antenna receives the strongest signals irrespective of the level of the satellite signal reaching the ground. At the same time the range of direction in which the antenna receives signals in a good condition is found on the basis of what is displayed on the display. The direction adjusting display generates a judgement reference level lower by a predetermined level than the peak level of the signal received by the antenna. The display judges the level of the received signal using the judgement reference level, and displays the result of judgement thereon.

    摘要: L'invention est fondée sur les études de la Demanderesse qui a montré que la puissance fournie par les moteurs entraînant le système en rotation était fonction de ces efforts. Une mesure de la puissance, ou de toute grandeur caractéristique de cette puissance (courant, cosφ, pression...) permet donc de mesurer simplement les efforts liés au vent. Si l'on se fixe une valeur de puissance (ou de grandeur caractéristique) limite liée à la vitesse limite du vent au-delà de laquelle les forces subies par le système sont trop importantes, on obtient facilement, moyennant une comparaison, une condition sur le fonctionnement des moteurs.
    L'invention permet également, pour des systèmes tournants effectuant une mesure d'angle, de faire une correction sur cette mesure.

    摘要: A motor (1) for driving the antenna (3) is connected to a source of power (5) for providing current for driving the motor. The source of power is connected to the motor by a pair of conductors and a voltage is developed across the pair of conductors. The system includes an arrangement for measuring and controlling the speed of the motor and therefore the antenna which includes a current interruption facility (7) for interrupting the current during a current interruption period. The current interruption period is adjustable whereby to adjust the speed of the motor (1) and thereby the antenna (3). The voltage developed across the pair of conductors is measured during the current interruption period. The voltage measured during the current interruption period is proportional to the speed of the antenna.
