Abstract: L'invention porte sur un appareil de validation de pièces de monnaie dont la vitesse de traitement des pièces a été améliorée. Cet appareil effectue un premier essai de validation sur des pièces de monnaie (3) en un premier point de validation (5) au fur et à mesure que des pièces de monnaie déboulent successivement le long d'une trajectoire de descente (4). Les pièces ne pouvant être acceptées passent par une trajectoire de rejet de pièces (12) alors que les pièces estimées acceptables lors du premier essai de validation sont déviées par une porte commandée par électro-aimant (11) vers une trajectoire d'acceptation de pièces (13). Les pièces acceptables passent par une bobine de détection supplémentaire (C4). Un microprocesseur (7) procède à un essai complémentaire en analysant le temps mis par la pièce pour atteindre le détecteur supplémentaire (C4) et s'en éloigner. Il exécute des routines de mesures d'insuffisance et de dépassement de temps (Figures 3A, B) et si le temps de passage de la pièce ne sort pas des plages définies par ces routines (t¿1?, t¿2?), celle-ci est acceptée. Lorsque le débit des pièces s'accroît, le programme de sous-temporisation est arrêté afin de permettre l'accélération du débit pour pièces valables sans pour autant nuire à la sécurité.

Abstract: An external modulation fiber optic transmitter includes an optical source, a predistorter for generating a distortion cancellation signal in response to a radio-frequency input, an electro-optic modulator for modulating the optical signal in response to the distortion cancellation signal, and an adaptive predistortion control circuit for providing a predistortion control signal to the predistorter. The adaptive predistortion control circuit includes a receiver for receiving the modulated optical signal output by the modulator, a filter for filtering the intermodulation distortion from the modulated optical signal to obtain a first distortion component, a distortion generator for receiving the radio-frequency input signal from the predistorter and generating a second distortion component in response to the radio-frequency input signal; a mixer for synchronously demodulating a product of the first and second distortion components to obtain a correction signal; and a lowpass filter and integrator for generating the predistortion control signal in response to the residual intermodulation distortion in the output of the electro-optic modulator. The predistorter modifies the distortion cancellation signal in response to the predistortion control signal, thereby reduçing distortion of the modified optical signal. Similarly, a method of adaptive predistortion control for optical external modulation includes the steps of generating a predistortion control signal; modulating an optical signal using the predistortion control signal; transmitting the modulated optical signal; receiving the modulated optical signal; filtering the modulated optical signal to obtain a first distortion component; generating a second distortion component using the predistortion control signal; synchronously demodulating a product of the first and second distortion components to obtain a second order correction signal and a third order correction signal; integrating the second order correction signal to generate a modulator bias control signal; and integrating the third order correction signal to control parameters of the predistorter, thereby modifying the predistortion control signal in response to the modulator bias control signal to reduce distortion of the modulated optical signal.

Abstract: In electromagnetic fields, such as are found in magnetic resonance imaging devices, the metal conductors and components used in most switches cannot be used because of their interaction with the field. In functional magnetic resonance imaging where the subject is expected to respond to, or initiate certain actions, that would commonly be recorded or initiated by activating a hand-switch or keypad, there has gone unmet a need for a low-cost switching device without conductive metal parts to perform these functions. A non-ferrous fiber optic switch is proposed to perform this function

Title: Horizontal axis wind turbine
Inventor: GISLASON NILS ERIK
IPC: F03D11/04
Filed: 1995-10-13
Abstract: A horizontal axis wind turbine comprises a rotor-supporting framework, a multi-vaned rotor, an electricity-generating stator, and a rotation track. The supporting framework is constructed with a plurality of triangular sub-units.  The rotor has a plurality of vanes projecting therefrom. The vanes have adjustable pitch and are encircled by a rim having a plurality of magnets.  Wind induces rotation of the rim. The stator is essentially stationary and is mounted on the framework opposite the rim. As magnets on the rotating rim pass by the stator, electricity is generated. The stator uses the pull of the magnets to automatically adjust itself to align with the rotating rim. The framework is mounted on the rotation track so that the framework can continually be adjusted to maximize wind-induced rotation of the rotor.
