Title: Device for generating focused elastic waves in a material medium such as underground, and method using same
Inventor: BARONI AXELLE
IPC: G01V1/00
Filed: 2001-12-19
Granted: 2011-06-14
Abstract: The invention concerns an electromechanical device for generating elastic waves in a material medium, such as underground in a frequency domain where the wavelengths of the generated waves are high relative to the dimensions of the device, and a method using said device. The device comprises one or several vibrators adapted to be buried in a medium, associated with a control system. Each vibrator comprises at least a centre mass (1), several head masses (2, 3) providing mechanical coupling with the medium, electromechanical transducers (4, 5) connecting the centre masses (1) to the head masses (2, 3). The control system (7) is adapted to apply to the various transducers (4, 5) respective control signals such that the resulting elastic wave field generated in the medium by the device, is oriented preferably along one or several directions. Said focused wave field can be directly obtained by applying appropriate control signals to the various transducers of each vibrator or by successively transmitting several times, with different wave fields, so that, by combining seismograms produced at those different times, the equivalent wave field is focused, or by combining the focused wave fields transmitted by several single vibrators. The invention is applicable to earth's seismic exploration for example.

Abstract: L'invention concerne un procédé permettant l'extraction des os internes de la partie avant d'une carasse fendue. Dans ce procédé, l'os du jarret, l'humérus et l'omoplate sont dégagés à la machine, ce qui permet de les séparer aisément du reste de la partie avant. Un outil (27a) de transport vient serrer le pourtour de l'extrémité de l'extrémité libre de l'os du jarret. La partie avant est ensuite déplacée au moyen d'un outil de transport qui la tire de manière à la faire passer devant les outils (1, 9, 15) de découpage, lesquels effectuent les opérations de découpage le long de l'os du jarret, de l'humérus et de l'omoplate, en étant guidés par ces os, de manière à libérer au moins partiellement les os du reste de la partie avant. Les articulations reliant l'os du jarret et l'humérus, et les jointures de l'humérus avec l'omoplate sont conservées au moins partiellement intactes pendant les opérations de découpage, de telle manière que lorsque l'outil (27a) de transport vient saisir l'extrémité libre de l'os du jarret sur son pourtour, sa force de traction est transférée aux os à travers ces jointures intactes.

Abstract: Data about computer network traffic is collected as user website visit recording sessions. The data captured is analyzed and organized with sufficient level of detail or granularity to determine a single request from a server. Each data request is analyzed to determine if it comes from a server with which an ongoing end user interaction or open site visit is occuring. If not, a new site visit is created as a general proposition. If the data request is part of an open site visit, then the time is compared to the time of the last interaction and if the interval is sufficiently small, the data request is treated as a continuation of the visit. If the interval is large, a new site visit is created.
