摘要： The invention relates to automatic outgoing and incoming channel balance and separation circuits between local telephone set lines and network junctors. The separation circuit associated with the telephone set lines possesses an electronic line feed circuit and a separator constituted by an operational amplifier whose output is connected via two equal resistors in series to one of the outputs of the electronic supply circuit, the junction of these two resistors being connected to the output of this separation circuit. The separation circuit associated with the junctor possesses two input amplifiers connected to the network via output resistors of equal value, one terminal of one of these output resistors being connected via a passive resistive and capacitative network to an operation amplifier, and the other terminal of this resistor being connected via a single resistor to this operational amplifier. Balance is provided for given values of the passive network components and for a given value of line impedance seen by the first separation circuit. The device possesses no adjustable components or transformers, and can be easily produced as an integrated circuit.

摘要： The demodulator therefore features a multiplexer connected to the different transmission channels. The output of the multiplexer is connected to a sampler-coder, followed by an interpolator, which is itself followed by a phase jump converter and a statistical decision device validating the code conversion result, when a certain number of samples taken in a series of successive samples have a phase jump in the same range of values.

摘要： The invention relates to simulators, for example, simulators of a ship's bridge and the visual display of the scene as viewed from that bridge. Elementary images are juxtaposed, forming an image of a large angle where, without discontinuity, a moving object appears on several television monitors positioned adjacent one another. The images are read simultaneously from "synthetic images" which are stored in a memory. The moving portion of the image, e.g. a ship, is inlayed in a background or environment image. The image of the object is furnished from a camera which is focused on a model of the object, in the example a ship or ships. There is a synchronization between the delayed line signal of the television camera in relation to the synchronizations of the signals throughout the system.
