Patent EP-0276507-A1 (EP)
Inventor: VAN ROERMUND ARTHUR HERMANUS M
IPC: H04H20/88
Filed: 1987-12-15
Abstract: Arrangement for decoding a stereo multiplex signal, comprising a baseband stereo signal (L+R), a stereo difference signal (L-R) which is amplitude-­modulated on a suppressed sub-carrier and a pilot signal located between the frequency bands of the said two signals, said arrangement having an input for the stereo multiplex signal and left and right stereo signal outputs, said input being coupled at one end  via  a pilot selection circuit to a phase-locked loop for regenerating the sub-­carrier and at the other end to a multiplier circuit for multiplying at least the modulated stereo difference signal by the regenerated sub-carrier. In order to improve the stereo channel separation the pilot selection circuit comprises a bandpass filter of the switched capacitor type a clock input of which is coupled to an output of a voltage-controlled oscillator incorporated in the loop. A mono-stereo control can be realised therein in a simple manner by varying the phase transfer of the last-mentioned bandpass filter at least at the pilot frequency in dependence upon a mono-stereo control signal.

Abstract: This invention relates to a process for making electrically conductive lines on a non-developable surface of an insulating substrate, to a tool for carrying out the process and to a device obtained thereby. The process consists in uniformly coating the surface of a layer of an electrically conductive matter, which is in turn coated with a layer of a protective matter. The contour of the lines is then traced mechanically on the layers by means of a tool hollowing out grooves, then the layers are subjected to the action of a chemical agent capable of attacking the layer of conductive matter without attacking the protective layer, after which those parts of the electrically conductive layer outside the lines are separated from the substrate by peeling. The invention is applicable, for example, to the making of electrically conductive lines on antenna reflectors.

Abstract: The device consists, for example, of an accelerometer incorporating a seismic mass (7) which is subjected to the mechanical vibrations to be detected. The vibrations act on a set of piezoelectric plates (5) which produce an output voltage across the wires (6). The voltage is used to control an electro-optical element (1) incorporating electrodes to which the wires (6) are connected. The electro-optical element (1) alters its light transmitting properties in response to the variations in the applied voltage. The element is connected to a light source and an electronic measuring circuit through a light guide (12) which may be a fibre-optic conductor (2, 3). The device is light and compact. It can transmit signals over a very wide range of frequencies and is not sensitive to external electromagnetic disturbance. <IMAGE>

Abstract: A groove (16) is disposed in a substrate (10) longitudinally along the outside radius of a bent integrated optical waveguide (11) to constrain the mode of optical energy propagating therein such that the optical energy that would normally be radiated is confined to the waveguide, thereby reducing transmission loss through the bend. Further, to reduce coupling loss between an integrated optical waveguide and an optical fiber, two grooves are disposed longitudinally along either side of the integrated optical waveguide to constrain the mode of optical energy propagating in the waveguide to approximate the mode of the optical energy propagating in the optical fiber. To further reduce both bend and coupling losses, the ends of the grooves (18) bend away from the waveguide.
