Abstract: An installation powers and controls a plurality of signaling lights arranged in series, each having at least one light source. The installation includes a unit with a primary power supply situated upstream for remotely programming or managing operation of the installation; a primary series circuit with a transformer for each signaling light; a control module for each signaling light; a secondary power supply circuit for powering the control modules, independent of the primary circuit; a first optical cable for bi-directionally connecting a first upstream module to the programming or managing unit; and a second optical cable for bi-directionally connecting a last downstream control module to the programming/management unit, with each control module being connected in series to an adjacent upstream module and to an adjacent downstream module by means of a respective bi-directional optical connection.

Abstract: A high-efficiency apparatus for real time measuring of parameters and operational times of vehicles running around a racetrack. At least one detecting station is arranged at a location along the racetrack and is set up to both receive and transmit radio frequency (RF) signals both from/to a transceiver unit installed on each vehicle, the transmitting from the transceiver unit being in response to the transmitting from the detecting station, the station being provided with an electronic radio frequency-converter for transmitting and modulating the received signals over a wide band coaxial cable.

Abstract: An automatic control system for a series circuit, in particular for airport signaling lights, physically separated from the work circuit feeding the lights and galvanically separated from the latter, includes a computer; several Main Stations each containing several Main Modules, each controlling several Remote Modules which check and act on a single airport light, each of said Main and Remote Modules having firmware boards; a full duplex transmission network linking the computer with the Main Stations; each Remote Module has externally two pairs of electric terminals of which one pair is connected to the secondary of an insulating transformer making part of the work circuit and the other pair is connected to a light or a group of lights being controlled, the two pairs of electric terminals being connected to each other by electrical leads, wherein connected in series to one of the electrical leads is a coil which is magnetically coupled to a Hall sensor of the Remote Module; and further including an electron
