MST device for attachment to an adhesive surface

A MST device for attachment to an adhesive surface, the MST device comprising: an attachment surface for abutting the adhesive surface; a first fluid conduit connected to a first aperture in the attachment surface; and, a recess in the attachment surface adjacent the first aperture to hold adhesive displaced from between the attachment surface and the adhesive surface when the MST device is attached such that displaced adhesive does not block fluid flow in the first conduit. By profiling the attachment surface so there is a recess next to the first aperture, there is less risk that adhesive will be squeezed into the conduit and impair fluid flow.

Method and apparatus for tuning an optical device

The present invention relates to a method and apparatus for tuning an optical fiber based optical device. An optical fiber device in accordance with the present invention is held at a first tension, and in accordance with the method of the present invention, heat is applied to the fiber to cause a release of tension. This can be used effectively to provide accurately tuned in-fiber Bragg gratings, or to trim fiber based interferometers. Advantageously, tuning method is significantly simplified over prior art methods. A further advantage is realized in that multiple fiber Bragg gratings can be packaged together and tuned separately, including multiple fibers or multiple gratings in a single fiber.

Instead of putting fiducial markers on both the film and the support member for alignment, the vision system use the fluid openings ...

Laminated film for mounting a MST device to a support member

A laminated film for mounting a MST device to a support structure for sealed fluid communication therebetween, the laminated film comprising: a polymer carrier web between two thermosetting adhesive layers; and, an opening formed in the film for establishing fluid communication between a first fluid conduit in the MST device and a second fluid conduit in the support member. Using a laminated film with thermosetting adhesive one each side provides a far more reliable seal than heated thermoplastic film. The bond between the thermoplastic film and the MST device surface is prone to thermal fatigue and leakage or outright failure. A laminate with a central carrier web and thermosetting adhesive can be drilled by a UV laser and later heated to a known curing temperature so that the adhesive sets and forms a strong bond to the MST device surface.

Bayesian Sequential Indicator Simulation of Lithology from Seismic Data

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.
