Abstract: System for reducing vibrations in the cabin of an aircraft driven by two or more propellers (12, 22) each having n blades (n being an integer equal or larger than 2) of which the relative phase angle can be adjusted, said system comprising synchrophase means (2) for adjusting said relative phase angle such that a predetermined relative phase angle is maintained. The system furthermore comprises means supplying information about the vibration level (3) at one or more positions within the cabin or thereto related information and for generating a thereto corresponding level signal, and a control unit (4) which in response to said level signal supplies an error signal to the synchrophase means causing the synchrophase means to adjust the blades of the various propellers such that a new relative phase angle is maintained which differs m.(2π/n) radians (m being an integer) from the previous relative phase angle.

Abstract: A fiducial implant (10) for the human body detectable by an imaging system (102) comprises a first portion (12) and a second portion (14). The first portion (12) is sufficiently large and comprised of a material for detection by an imaging system (102), and sufficiently small to avoid the distortion of the skin when placed at an interface between the skin and the bone. The first portion (12) also has at least a portion which is spherical and defines a surface (16) for cooperating with a tool for securing the second portion to the bone (18). The second portion (14) is configured for fixed attachment to a bone (18) beneath the skin without penetrating entirely through the bone and without fracturing the bone (18). Additionally, the placement of n fiducial implants (where n≧4) into a portion of anatomy of the human body allows for the generation of a particular image slice of the portion of the anatomy taken by an imaging system with respect to a first time period, at subsequent imaging sessions and also with different scan modalities. This provides a doctor with the ability to accurately follow the progress of the portion of the anatomy of interest. Moreover, the existence of fiducial implants   allows a target to be identified within the portion of anatomy relative to an external coordinate system. The portion of anatomy with the target may then be operated on, for instance, robotically, or precisely irradiated.

Abstract: La présente invention utilise la stimulation neuromusculaire fonctionnelle (40) exercée au moyen d'électrodes (21, 22, 23, 24). Le signal électromyographique de réaction est détecté par des électrodes (31, 32, 33, 34) assurant une reconnaissance de structure (60) du signal électromyographique de réaction, dont on identifie des paramètres de structure dont la variation dans le temps est fonction de la progression de la fatigue musculaire. Cette variation dans le temps est utilisée pour régler la largeur d'impulsion et/ou le niveau d'impulsion (50) de la stimulation neuromusculaire fonctionnelle, de façon à compenser cette fatigue d'une manière automatique qui ne nécessite pas l'attention du patient. La présente invention se rapporte également à des usages diagnostics de cette reconnaissance de structure et à un générateur de contractions musculaires autres que celles nécessaires pour assurer la position debout ou la marche.

Lorsque les éléments optiques (16, 18) oscillent, le faisceau focalisé tremble au-dessus et au-dessous de la surface du support d'enregistrement (12). Lorsque la région de focalisation du rayon laser (26) se trouve dans le plan de la surface d'enregistrement (12), une piqûre ou une déformation (52) se forme dans la surface. Un mouvement relatif entre la surface d'enregistrement (12) et le point de focalisation du rayon laser (26) est prévu pour écrire sur la surface d'enregistrement (12).

Abstract: A waveguide-type optical circuit element which is equipped with a directional coupler that varies the intensity of light between two waveguides, and is used as a polarization-independent optical switch or a variable light- branching filter for optical fiber communication, etc. The length of the coupling portion of two waveguides (2) and (3) is, in the case of the TE mode, about three times as long as the complete coupling length of the TE mode. In the case of the TM mode, the length is nearly equal to the complete coupling length of the TM mode. Electrodes (4) and (5) each divided into three parts are inverted-Δβ electrodes in which the direction of the electric field is inverted alternately. Thus, the effect of confining the light in the waveguides is enhanced, and the driving voltage for optical switching is low. Optimum element characteristics are obtained according to the ratio of variations of the propagation constants of the TE and TM modes of the directional coupler fabricated.

Abstract: A method for steering, stopping and parking an aircraft in a preselected docking position of an aircraft apron and parking point, especially a point which is located at the side of a passenger bridge that is provided for the aircraft to dock with said passenger bridge. A steering system is used which has a sensor unit, which scans the aircraft rolling past or rolling up to the point, and has a display unit, the display unit informing the aircraft pilot of the distance remaining to the docking position and that the docking position has been reached. During the movement of the aircraft to the docking position, or away from the docking position, the elements of the sensor unit use measuring techniques to detect the aircraft approaching or moving away from a predetermined guidance line, and lateral deviations of the aircraft from said line. The output signals of the sensor unit are supplied to a computer which calculates the aircraft approaching or moving away from the guidance line, and lateral deviations of the aircraft from said line, and displays to the pilots, on the display device, information derived therefrom for the necessary steering and driving movements. <IMAGE>

Abstract: A co-ordinate measuring machine has a probe (62) used to touch points on an article (61) under manual control by a user, e.g. from a joystick (69). A computer (71) determines a vector describing the direction of probe movement prior to touching each point. On the basis of the number of points touched by the user and their respective vectors, the computer makes a decision as to the shape of a feature of the article under inspection, e.g. whether it is a flange, slot, boss, bore, internal sphere, external sphere, cylinder or cone. It can then either calculate a relevant geometrical parameter such as a dimension of the feature, or write a part program for future inspection of the feature on further, nominally identical articles (61). This can be done automatically without the need for the user to tell the computer anything about the shape of the feature concerned.
