Abstract: A dynamometer is used to dynamically evaluate an electrical submersible pump (“ESP”) motor while both are inside of a well. The dynamometer includes a ESP dyno that is mechanically coupled to the ESP motor. The ESP motor and ESP dyno can be a permanent magnet motor or an induction motor, and can have the same or similar values of inertia. Energy absorbed by the ESP dyno can be regenerated as electricity that is transmitted back to a power source, or converted to heat energy in a resistive load bank.

Abstract: An image rendering method comprising the steps of: (a) performing a noisy estimation of a given view of a given scene of said image using a Monte-Carlo stochastic renderer, wherein general information of each ray sample, such as color and position in the image plane, is stored, (b) calculating a similarity measure between two sets of samples cast from two pixels of said scene and their neighbors, and (c) generating an output image wherein each pixel color is a weighted combination of the pixel colors generated from (a) with weights based on the similarity measure of (b) between the respective set of samples cast from the pixels and their neighbors.

Abstract: The invention relates to a method for exchanging a 3D view between a first and a second user having both a piece of software for creating 3D views. A view is created by the first user. This view comprises an encrypted object, the first user being licensed for the encrypted object. This view is stored in a file by the first user. The encrypted object is encrypted and the result of this encryption is stored as encrypted data in the file. According to the invention, non-encrypted data defining the encrypted object is stored in the file in parallel to the encrypted data relating to the encrypted object. This non-encrypted data can be read by the second user, so that the second user can see the encrypted object if he has acquired a license for this object, or a basic representation of the encrypted object if he has not acquired a license.

Abstract: A process for creating three-dimensional or relief views with the help of software running on a computer system for adjusting brightness of a scene comprising a plurality of pixels includes: determining a representative brightness of at least one predetermined area of the scene based on brightness of each pixel of the at least one predetermined area; comparing the average brightness to a reference value; and correcting the brightness of at least a portion of the scene in accordance with a result of the comparison.

Abstract: The invention relates to a method permitting, in a simple and ergonomic manner, the development of a file library associated with a software product determined by a user, this user having an item of computing equipment. The inventive method comprises: a step, for the operator, of associating, with each file, a presentation file to which items of destination information including the specification of a determined location of the file library are associated so that the presentation files can be presented in the item of equipment of the user at the same time the presentation files are already located in the library.

Abstract: A method for generating 3D landscapes which comprises the steps of selecting a plurality of 3D elements from a library of vegetative elements and distributing the 3D elements. The method either distributes the 3D elements on a terrain so that parameters of the 3D elements depend on an environment of the 3D elements or with a variable distribution density such that the parameters of the 3D elements depend on the variable distribution density. The parameters comprises the nature of the 3D elements, distribution density of the 3D elements, and their size, orientation, color and shape. The environment comprises an altitude of the terrain, a slope of the terrain, a position of the 3D elements relative to objects or other 3D elements on the terrain.

Abstract: A method for manufacturing an application software by providing data comprising the software content and data comprising at least media serial code specific to the application. The media serial code is used to provide a personalized application software. The method also provides data comprising a primary computer program, which is used to authenticate the media serial code.
