Abstract: Électrode de défibrillation destiné à l'implantation sur ou dans la région du coeur d'un patient et relié à système de défibrillation. L'électrode comporte une pluralité d'éléments conducteurs d'électricité qui, espacés et interconnectés, ont pour effet d'augmenter le nombre de points de décharge sur l'électrode. Dans une première version de l'invention, l'électrode comporte une pluralité de cercles conducteurs concentriques qui sont interconnectés. Dans une deuxième version de l'invention, l'électrode comporte une pluralité d'éléments électriques conducteurs planaires qui sont interconnectés dans une configuration rappelant un casse-tête. Dans une troisième version de l'invention, l'électrode comporte des fils conducteurs enroulés autour d'un cathéter intracardiaque. Dans une quatrième version de l'invention, des fils conducteurs sont enroulés dans une configuration de spirale concentrique. Dans une cinquième version spécifique de l'invention, la partie distal d'un cathéter intracardiaque comporte une pluralité de sites conducteurs isolés. Dans toutes les version indiquées ci-dessus, la décharge d'énergie électrique de l'électrode à la surface du coeur se fait par tous les points de décharge des composants conducteurs. Le nombre accru de points de décharge assure donc une distribution plus uniforme de l'énergie vers le coeur. En outre, pour une efficacité plus grande encore, chacune des configurations proposées peut être fabriquée sans support isolant.

Abstract: A  multi-function  ALU  for  use  in  digital  data processing is described, which facilitates the execution of instructions in parallel, thereby increasing processor performance.    The   proposed   apparatus   reduces   the instruction  execution  latency  that  results  from  data dependency hazards in a pipelined machine.  This latency reduction is accomplished by collapsing the interlocks due to these hazards.   The proposed apparatus achieves performance improvement while maintaining compatibility with previous implementations designed using an identical architecture.

Abstract: ABSTRACT             A horizontal deflection circuit output stage generates a retrace pulse in a tertiary winding of a flyback transformer. A flyback pulse that is substantially wider than the retrace pulse is produced in a winding of a second transformer that is coupled in series with the tertiary winding such that the retrace pulse occurs when a peak portion of the flyback pulse is already relatively "flat". The amplitude of the flyback pulse is controlled in a negative feedback loop for stabilizing an ultor voltage.

Abstract: A device for remotely controlling a multi-axial device has: an arm on which an operator's arm is set; a handle connected to front end of the arm; and joints for the arm and the handle.  By the operation of the operator's arm and hand set on the arm and handle, the arm can be extended and horizontally and vertically pivoted, and the handle can be horizontally and vertically pivoted and, preferably, rolled as well.  The arm portion outputs operational changes with respect to three axes of the horizontal rotation, the vertical rotation and the extending movement.  The arm front portion outputs operational changes with respect to the three axes of the horizontal, vertical and rolling rotations.  Thus, the number of axes employed in the master can be increased to detect a variety of movements thereof.          The operational directions of the joy stick agree with the directions of the three rectangular coordinate axes.  Thus, the device provides three-dimensional data regarding position and angle.

Abstract: Système de traitement numérique des images qui numérise et stocke des images qui se trouvent sur film photographique selon l'orientation dans laquelle elles ont été captées sur film, ce qui résout le problème que constitue le besoin de faire tourner matériellement le numériseur de film pour les images orientées verticalement, et qui réduit considérablement la complexité et le coût du numériseur.  Au lieu de faire tourner matériellement le numériseur, un fichier de contrôle de présentation est associé à chaque fichier d'image stocké.  Le fichier de contrôle de présentation contient de l'information relative à l'orientation et au rapport des dimensions verticale et horizontale de l'image, ce qui permet au dispositif de lecture de l'image de savoir de quelle manière chaque image a été stockée dans la base d'image numérique, p. ex. sur disque compact.  Lorsque le disque est introduit dans un dispositif de lecture afin de commander un dispositif de sortie comme un moniteur de télévision couleur, le dispositif de lecture peut facilement décoder l'information de contrôle de lecture pendant la lecture de l'image numérisée, ce qui fait que l'image sera orientée dans le sens approprié et avec le rapport des dimensions verticale et horizontale approprié.

Title: Resolver analog to digital converter
Inventor: YUNDT GEORGE B
IPC: G01D5/245
Filed: 1992-05-22
Granted: 1998-10-27
Abstract: An apparatus, preferably in the form of a resolver to digital converter for converting the amplitude modulated, encoded signals into digital signals representative of the velocity and position is described.  The apparatus is of the type that includes an electronic control transformer circuit for providing respective products of sine and cosine analog signals respectively times the cosine and sine of the digital position signals and for differencing the products so as to produce an analog AC error signal. The improvement comprises means for converting the analog AC error signal into a digital DC error signal and a digital accumulator for time integrating the DC error signal to generate the digital position signal. In a preferred embodiment the output of the accumulator is digitally modulated so as to provide the digital position signal as a bit-reduced feedback signal to the electronic control transformer.

Patent CA-2074446-C (CA)
Title: Cassette seal
Inventor: SCHMITT WOLFGANG
IPC: F16J15/3264
Filed: 1992-07-22
Granted: 1998-07-21
Abstract: A cassette seal for a rotatable shaft includes an outer ring and an inner ring of opposite, angular profile.  The rings together define an annular chamber with an assumed concentrical axis.  The outer ring is provided with at least one sealing lip for resting against the inner ring which includes a radial flange.  The outer ring and the flange define a gap therebetween which connects a space to be sealed with the annular chamber.  On the side directed away from the flange, the gap widens into circumferentially evenly distributed cut-out segments of the outer sing.  The cut-out segments provide channels which connect the annular chamber with the space to be sealed.  The channels are defined in axial direction on the side remote from the flange by a conically inclined drainage surface of the outer ring.  The diameter of the conically inclined drainage surface widens towards the annular chamber. The drainage surface in axial direction completely surrounds the flange and at least partly surrounds the sealing lip.  This improves both the cooling and the lubrication of the sealing lip which results in a cassette seal of longer service life.  The simple arrangement of the small number of component parts of the cassette seal provides for an economical manufacture and an easy and safe installation.

Title: Total internal reflection-type optical waveguide switch
Inventor: KAMATA YOSHIYUKI
IPC: G02F1/313
Filed: 1992-10-14
Granted: 1999-12-21
Abstract: In a total internal reflection-type optical waveguide switch which comprises optical waveguides crossing each other so that a refractive index changing region for developing a reflective surface is formed at a crossing section between the waveguides, the refractive index changing region has a configuration such that the reflective surface constitutes a concave surface recessed with respect to one lateral portion of the crossing section. When the refractive index changing region is not activated, incident light upon the spot corresponding to the reflective surface is insensitive to changes of the refractive index in the refractive index changing region, so that the initial crosstalk level can be lowered.
