Title: Methods and computer executable instructions for rapidly calculating simulated particle transport through geometrically modeled treatment volumes having uniform volume elements for use in radiotherapy
Inventor: WESSOL DANIEL E
IPC: A61N5/10
Filed: 1999-04-22
Abstract: Methods and computer executable instructions are disclosed for ultimately developing a dosimetry plan for a treatment volume targeted for irradiation during cancer therapy. The dosimetry plan is available in "real-time" which especially enhances clinical use for in vivo applications. The real-time is achieved because of the novel geometric model constructed for the planned treatment volume which, in turn, allows for rapid calculations to be performed for simulated movements of particles along particle tracks there through. The particles are exemplary representations of neutrons emanating from a neutron source during BNCT. In a preferred embodiment, a medical image having a plurality of pixels of information representative of a treatment volume is obtained. The pixels are: (i) converted into a plurality of substantially uniform volume elements having substantially the same shape and volume of the pixels, and (ii) arranged into a geometric model of the treatment volume. An anatomical material associated with each uniform volume element is defined and stored. Thereafter, a movement of a particle along a particle track is defined through the geometric model along a primary direction of movement that begins in a starting element of the uniform volume elements and traverses to a next element of the uniform volume elements. The particle movement along the particle track is effectuated in integer based increments along the primary direction of movement until a position of intersection occurs that represents a condition where the anatomical material of the next element is substantially different from the anatomical material of the starting element.  This position of intersection is then useful for indicating whether a neutron has been captured, scattered or exited from the geometric model. From this intersection, a distribution of radiation doses can be computed for use in the cancer therapy. The foregoing represents an advance in computational times by multiple factors of time magnitudes.

Abstract: L'invention concerne un dispositif de comptage d'une population de poissons, permettant de compter le nombre de poissons passant à travers une passe à poissons, sur la base de la direction des poissons et de leur taille. Des données d'images produites par une caméra à ligne double (1) captant des images simultanément sur deux lignes de prise de vue (A, B), sont envoyées par un convertisseur analogique-numérique (2) et mémorisées une ligne après l'autre dans des mémoires d'images (3A, 3B). Les données d'images sont ensuite transférées à l'unité de traitement (6) où elles sont réarrangées dans l'ordre de prise de vue pour chaque ligne de prise de vue (A, B), de manière à générer des images successives de ligne double (A, B). A partir de ces images successives de ligne double (A, B), on trace les contours des zones dont les numéros d'étiquettes sont les mêmes, pour séparer les figures massives éparpillées dans les images. On extrait les caractéristiques des figures massives et on les compare à un motif standard pour déterminer si les figures massives sont des poissons ou non. Ensuite, on identifie une à une les positions et les formes de tous les poissons éparpillés dans les images successives de ligne double (A, B) pour compter le nombre de poissons qui sont passés par les lignes de prise de vue (A, B) pendant une période déterminée. En outre, on considère que les poissons individuels se trouvant à des positions mobiles représentent le même poisson et, sur la base des déplacements de ces poissons, on calcule la direction et la vitesse de ces poissons. On détermine, à partir de la vitesse des poissons, la taille de chaque poisson. On détermine le nombre de poissons à partir de la taille et de la direction des poissons.

Title: Battery charging circuit
Inventor: KELLY DAVID
IPC: H02M3/335
Filed: 2000-02-10
Abstract: A battery charging circuit uses a simplified design for converting AC to DC and powering a flyback transformer.      The switch of the flyback transformer operates at a high frequency and the time of the transformer is controlled to achieve a high power factor. The flyback transformer is fed a rectified AC signal which has not been smoothed in the traditional manner using a bulk hold capacitor and in rush limiting resister. Any treating to smooth the charging current for the battery is carried out on the secondary side. In many cases, no smoothing of the charging current is necessary. The time on of the switch is changed if necessary, slowly, relative to the pulsating input signals powering the primary winding. With a fixed T on, or slowly varying T on, dramatic fluctuations in the charging current are avoided.

Title: Method and apparatus for queue modeling
Inventor: BORDEN MARTY
IPC: H04L12/56
Filed: 2000-06-01
Abstract: A method, apparatus, and computer program product for modeling dynamics of a queue are disclosed. A queue law function can be used to determine a control function for use in a congestion control module in a network for dropping packets. A  queue law function may be determined based upon traffic conditions in the network. First a quantity that is representative of the link utilization between first and second nodes is determined. If the link is fully utilized, a quantity that is representative of an average round transmission trip time for data to be sent from the first node to the second node and an acknowledgment to be received by the first node is calculated. The queue law function which is dependent on a data drop probability based upon the link utilization, the buffer size, and the average round trip transmission time is determined. From this queue law function, parameters for defining a control function can be derived. These parameters include the minimum buffer size and the maximum expected queue size during normal operation for the node.
