Title: Procede et appareil d'arbitrage de collision pour lire plusieurs etiquettes d'identification radioelectrique
Inventor: DOANY ZIYAD H
IPC: G06K19/07
Filed: 2000-06-01
Granted: 2008-08-05
Abstract: L'invention porte sur un procédé permettant de lire simultanément un numéro séquentiel et/ou d'autres informations à partir de plusieurs signaux radioélectriques en collision émis par des étiquettes (1-5) d'identification. L'invention ne nécessite d'un supplément de circuit logique minimal dans le processeur d'étiquettes tout en assurant avec puissance et rapidité les fonctions habituelles de tri et d'identification. En l'occurrence, on recours à un canal de communication primaire pour plusieurs canaux secondaires. Une tête de localisation ou de lecture (6) interroge les étiquettes (1-5) qui réagissent à un signal radioélectrique. En cas de réception de plusieurs signaux, la tête de localisation ou de lecture (6) sollicite les étiquettes (1-5) d'identification radioélectrique et leur demande d'émettre une autre réponse qui est transmise à l'un des canaux secondaires en fonction de leur numéro d'identification, ce qui force les étiquettes à se trier au niveau des canaux secondaires. L'affectation des canaux secondaires aux étiquettes (1-5) se fait sur la base des numéros d'identification. La tête de lecture (6) détecte ensuite un accusé de réception dans les canaux secondaires occupés et demande à une étiquette (1-5) d'un canal spécifique de passer dans le canal primaire. Après émission du signal dans le canal primaire, la tête de lecture (6) lit le numéro d'identification. S'il y a une autre collision, les étiquettes entrées en collision sont renvoyées au canal secondaire et triées à nouveau sur la base d'une autre partie de leur numéro d'identification. Ce procédé se poursuit jusqu'à ce que toutes les étiquettes (1-5) soient triées et identifiées. Lorsque toutes les étiquettes (1-5) ont été triées, elles sont affectées alors à un autre canal distinct des canaux secondaires qui sont utilisés pour le tri.

Title: Method and apparatus for visualization of 3d voxel data using lit opacity volumes with shading
Inventor: REPIN DMITRIY G
IPC: G06T15/50
Filed: 2001-12-14
Granted: 2009-02-17
Abstract: A volume rendering process is disclosed for improving the visual quality of images produced by rendering and displaying volumetric data in voxel format for the display of three-dimensional data on a two-dimensional display, with opacity (1402) and shading (1404) to control the realistic display of images rendered from the voxels. The process includes partitioning the plurality of voxels among a plurality of slices with each slice corresponding to a respective region of the volume. Each voxel includes an opacity value adjusted by applying an opacity curve to the value. The opacity value of each voxel in each cell in the volume is converted into a new visual opacity value that is used to calculate a new visual opacity gradient (1403) for only one voxel in the center of each cell. The visual opacity gradient is used to calculate the shading used to modify the color of the individual voxels based on the orientation of opacity isosurfaces passing through each voxel in the volume in order to create a high quality realistic image.

Title: Method and apparatus for determining modulation scheme for retransmission in a communication system
Inventor: HA SANG-HYUCK
IPC: H04L27/00
Filed: 2002-11-20
Granted: 2010-10-12
Abstract: A method and apparatus for determining an optimum modulation scheme for a retransmission in a communication system supporting HARQ. When two modulation schemes are available, at an initial transmission, information is modulated in the lower-order modulation scheme if a first MPR is less than a first threshold, and in the higher-order modulation scheme if the first MPR is greater than or equal to the first threshold. Here, an MPR is determined by an EP size, the number of available Walsh codes, and the number of slots per sub-packet that are used for a transmission. To select one of the modulation schemes for a retransmission, a second MPR is calculated using an EP size, the number of Walsh codes, and the number of slots per sub-packet that are used for the retransmission. If the first MPR is equal to or less than a second threshold and greater than the first threshold, the lower-order modulation scheme is selected. If the second MPR is greater than the second threshold, the higher-order modulation scheme is selected.

Title: 2-d inversion of multi-component induction logging data to resolve anisotropic resistivity structure
Inventor: ZHANG ZHIYI
IPC: G01V3/28
Filed: 2002-03-01
Granted: 2012-08-28
Abstract: High Definition Inductio Logging (HDIL) tools (10) can provide reliable information about the vertical and radial variations of resistivity (Rh1, Rv1, Rhi, Rvi) structure in isotropic media (201a, 201i). This type of logging tool utilizes transmitter-receiver arrays (101, 103, 105, 107, 109, 111, 113, 115) coaxial with the borehole (2) and thus cannot provide information about anisotropy in vertical wells. This greatly limits the application of array induction tools in the characterization of reservoirs with finely laminated sand/shale (4A-4E) sequences. A multi-component induction 3DEX tool provides the much needed ability to detect anisotropy for sand-shale laminated reservoirs. Data from such a logging tool lacks the radial resolution provides by array induction tools. Joint inversion of HDIL and 3DEX data is able to identify parameters of the invaded zone as well as anisotropic formations.

Granted: 2008-08-26
Abstract: A vibratory transducer for a fluid flowing in a pipe comprising a curved flow tube for conducting the fluid. The flow tube communicates with the pipe via an inlet-side tube section and an outlet-side tube section. An antivibrator is mechanically connected with the flow tube by means of a first coupler on the inlet side and by means of a second coupler on the outlet side. During operation of the transducer flow tube and antivibrator oscillates in opposition of phase. For driving flow tube and antivibrator the transducer comprising an excitation system and for sensing inlet-side and outlet-side vibrations of the flow tube the transducer comprising a sensor system. An internal system formed by at least said flow tube, said antivibrator, said excitation system, and said sensor system, oscillating about a longitudinal axis of the transducer which is essentially in alignment with the inlet-side tube sections, forces a torsion of the first and second couplers about the longitudinal axis and an essentially torsional elastic deformation of at least parts of the inlet--side and outlet-side tube sections. In order to achieve a torsionally soft oscillation of the internal system, at least the first coupler, tuned to a torsional rigidity of the inlet-side tube section, and at least the second coupler, tuned to a torsional rigidity of the outlet-side tube section, are so dimensioned that an inlet-side inherent torsion eigenmode of the first coupler and of the inlet-side tube section has a natural frequency approximately equal to the excitation frequency, and an outlet-side inherent torsion eigenmode of the second coupler and of the outlet-side tube section has a natural frequency essentially equal to the natural frequency of the inlet-side inherent torsion eigenmode.
