Abstract: An interactive system for a local intervention inside a region of a non-homogeneous structure, such as the skull of a patient, which is related to the frame of reference (R2) of an operation table, and which is connected to a reference structure comprising a plurality of base points. The system creates on a screen a representation of the non-homogeneous structure and of the reference structure connected thereto, provides the coordinates of the images of the base points in the first frame of reference (R1), allows the marking of the coordinates of the base points in R2, and allows the carrying out of the local intervention with an active member such as a trephining tool, a needle, or a radioactive or chemical implant. The systems also optimizes the transfer of reference frames between R1 and R2, from the coordinates of the base points in R2 and the images in R1 by reducing down to a minimum the deviations between the coordinates of images in R1 and the base points in R1 after transfer. The system also establishes real time bi-directional coupling between: (1) an origin and a direction of intervention simulated on the screen, (2) the position of the active member.

Granted: 2003-07-01
Abstract: A water-absorbent water-insoluble fibre or film is produced by extruding an aqueous solution of a water-soluble polymer into a gaseous medium to form fibre or film. The extruded fibre or film is collected at a moisture content of 8 to 25 % based on the dry weight of flee fibre or film and is further dried at a temperture no greater than 100 °C before crosslinking the fibre or film at a temperature in the range 125 to 250 °C to a degree sufficient that the crosslinked fibre or film is water-insoluble. The fibre or film entering the crosslinking step has a moisture content which is reduced, preferably by at least 5 %, and which is in the range 0 to 10 %. Heat-crosslinked fibre is preferably treated with moist air after crosslinking to raise the moisture content of the fibre to at least 10 %, particularly if the fibre is for textile processing. Water-absorbent water-insoluble coatings can be produced by a simi-lar process:

IPC: G01V1/30
Filed: 1995-03-10
Granted: 1998-10-20
Abstract: A discretized lithologic model of the subsurface is defined by a regular array of pixels. Each pixel corresponds to one of a finite number of possible lithoclasses such as sand, shale or dolomite. The lithoclasses are unknown except at a small number of sparsely distributed control pixels associated with borehole locations. Associated with each pixel there is a multivariate record of seismic attributes that may be statistically correlatable with the local lithology. A Monte Carlo method is used to simulate the lithoclass spatial distribution by combining the lithologic data at control pixels with the seismic-attribute data records. Using Indicator Kriging, a prior probability distribution of the lithoclasses is calculated for each pixel from the lithology values at neighboring pixels. The likelihood of each lithoclass is also calculated in each pixel from the corresponding conditional probability distribution of seismic attributes. A posterior lithoclass probability distribution is obtained at each pixel by multiplying the prior distribution and the likelihood function. The posterior distributions are sampled pixel-by-pixel to generate equally probable models of the subsurface lithology.
