Title: Interpretation methods for nmr diffusion-t2 maps
Inventor: MINH CHANH CAO
IPC: G01V3/14
Filed: 2004-01-28
Abstract: A method is disclosed for interpretation of multi-dimensional nuclear magnetic resonance data taken on a sample of an earth formation. Specifically, a set of NMR data is acquired for a fluid sample located either in a borehole or in a laboratory environment. From the set of NMR data, a multi-dimensional distribution is calculated using a mathematical inversion that is independent of prior knowledge of fluid sample properties. The multi-dimensional distribution is graphically displayed on a multi- dimensional map. Each fluid instance or artifact visible on the graph is identified as representing a probable existence of a detected fluid. One or more quantitative formation evaluation answers for one or more fluid instances is computed based on the multi-dimensional distribution associated with the respective fluid instance.

Abstract: The invention disclosed herein is a flow baffle (34) for providing a generally uniform flow to a fluid within a catalytic firebox reactor (10), which is characterized by a single flow channel (24). The invention, however, has general application to any single flow channel device. The flow baffle (34) is inserted within the reactor (10) in the single flow channel (24) to cause the fluid flowing in the single flow channel (24) to have a generally uniform flow field, instead of preferentially flowing down a periphery of the channel (24).  The uniform flow field promotes the design optimization of the catalytic reactor (10).

Abstract: A mobile apparatus for assisting a person with limited mobility. The apparat us is also for developing a higher level of mobility in a person having low mobility. The person may be assisted by the apparatus when walking. The apparatus includes a seating surface resiliently mounted to provide partial body weight support to the person. A person using the mobility assist may grasp lateral handles disposed on the apparatus while walking or he/she may attempt to mobilize without the use of the later al handles. Multiple elastic cords positioned to generate a lifting force that varies according to the number of elastic cords employed provide the degree of resilience in the sea t. The degree of resilience may be adjusted in accordance with the relative collapse of th e lower extremities of the person. As the walking ability of the person progresses, such lifting force may be reduced overtime by reducing the number of elastic cords employed.

Abstract: A raster-to-vector conversion process for converting a pattern descriptive coded image into a vector coded image. A progress marking plane with structural elements determined as a function of pattern data in the image is created in pattern descriptive format. The progress marking plane is pre-loaded with index data stored in the structural elements and indicative of an aspect similarity between image-forming units in the image. Object contours in the image are searched as a function of an aspect correlation between the image-forming units as determined from the index data. The faces of the image-forming units explored while searching are marked in associated ones of the structural elements of the progress marking plane, to prevent a face forming a part of an object contour found while searching from being considered again. Vector data representative of the faces of image-forming units defining the object contours found while searching are generated and the vector image is produced by assembling the vector data.

Abstract: My invention the "CANADIAN CAP" with the Maple Leaf shape pear would be a part of the new millennium Canadian heritage, which would promote successfully our country Canada around the world! It can be done in very colourful fabrics, skin, plastic and from other materials. The unlimited types of shapes and colours would make it a very attractive for its user, and also, it would be a very simple, unique and useful Canadian symbol beside the national flag, which would unite all Canadians. However, Mexicans are proud of their "sombreros", therefore, Canadians deserve for something simple, unique, and very practical Canadian identity, what would make them proud and different. I strongly believe that the real Canadian Cap will be the most visible and recognizable Canadian ambassador around the world without a huge spending! Don't you agree?
