Title: Biodegradable surfactant for invert emulsion drilling fluid
Inventor: PATEL ARVIND D
IPC: C09K8/36
Filed: 2002-08-09
Granted: 2010-10-19
Abstract: An invert emulsion drilling fluid includes an oleaginous continuous phase; a non-oleaginous discontinuous phase; a biodegradable surfactant including a di-fatty acid ester of triglycerol; and a weighting agent. It is preferred that the fatty acid have the formula RCO2H in which R is an alkyl or akenyl having 10 to 20 carbon atoms. The oleaginous fluid is selected from diesel oil, mineral oil, synthetic oil, ester oils, glycerides of fatty acids, aliphatic esters, aliphatic ethers, aliphatic acetals, or other such hydrocarbons and combinations of these and similar compounds. The non-oleaginous phase is selected from fresh water, sea water, brine, aqueous solutions containing water soluble organic salts, water soluble alcohols or water soluble glycols or combinations of these and similar compounds. The weighting agent is any suitable weighting agent and is preferably selected from water insoluble weighting agents such as barite, calcite, mullite, gallena, manganese oxides, iron oxides, or combinations of these or water soluble weighting agents such as water soluble salts of zinc, iron, barium, calcium or combinations of these and similar compounds.

Title: A signal processing method and device for signal-to-noise improvement
Inventor: WASSERMAN YORAM
IPC: A61B5/00

Abstract: A method and apparatus extract is a signal component of a measured signal using one of two methods. If the signal component in the measured signal is a periodic signal with a certain well-defined peak-to-peak intensity value, upper and lower envelopes of the measured signal. This signal component can further be used to calculate a desired parameter of the sample. The DC component of the signal is determined as the median value of the upper envelope, and the AC component is determined as the median value of the difference between the upper and lower envelopes. If the signal component of the measured signal is a periodic signal characterized by a specific asymmetric shape, a specific adaptive filtering is applied to the measured signal, resulting in the enhancement of the signal component relative to a noise component. This adaptive filtering is based on a derivative of the Gaussian Kernel having specific parameters matching the characteristics of the signal component.

Abstract: L'invention concerne une valve de régulation de liquides (10) permettant de réguler, au moyen d'une valve unique, un écoulement entre une source de solution saline (12), une source de substance de contraste (13), un réservoir de liquides résiduels (14) et un cathéter (15). Cette valve de régulation de liquides comprend trois positions principales, et notamment une position de circulation de substance de contraste dans laquelle la valve assure une communication entre un injecteur et une source de substance de contraste tout en isolant la source de solution saline et le cathéter. Ladite valve peut également être mise dans une position de circulation de solution saline/liquides résiduels dans laquelle elle assure une communication entre l'injecteur et la source de solution saline et/ou le réservoir de liquides résiduels tout en isolant la source de substance de contraste et le cathéter. La valve peut en outre être mise dans une position d'injection dans laquelle elle assure une communication entre l'injecteur et le cathéter. Une valve unique remplit ces trois fonctions. Cette valve peut également assurer une communication entre un transducteur de pression (32) et un cathéter (15) pendant le chargement de la solution saline, l'évacuation des liquides résiduels et le chargement de la substance de contraste. Par ailleurs, ladite valve assure la protection ou l'isolation du transducteur de pression pendant les opérations d'injection.

Abstract: The invention relates to a method of qualitatively evaluating a digital audio signal. It is characterized in that it calculates a quality indicator consisting of a vector associated with each time window in real time, in continuous time, and in successive time windows. For example, the generation of a quality indicator vector calculates, for a reference audio signal and for an audio signal to be evaluated, the spectral power density of the audio signal, the coefficients of a prediction filter, using an autoregressive method, a temporal activity of the signal or the minimum value of the spectrum in successive blocks of the signal. To evaluate the deterioration of the audio signal, the method may calculate a distance between the vectors of the reference audio signal and the audio signal to be evaluated associated with each time window.

Filed: 2004-11-04
Granted: 2010-05-18
Abstract: The present invention is an apparatus and method for marking the mail stop of an article of internal or interdepartmental mail. The apparatus consists of a matrix of boxes representing alphanumeric characters, a portion of which that are marked or are scratched or blackened out by the sender to represent a destination mail stop code. The matrix further comprises a lead-in marker and a lead-out marker used by an optical scanner of a mail sorting machine to determine the location and orientation of the matrix affixed or printed on the article of mail and to, thereby, decode the mail stop code marked on the matrix. The method of the present invention consists of scanning an article having such a label printed on it whereby the destination mail code is marked on the label. The method then determines if the marked mail stop code matches a destination known to the mail sorting machine and, if so, routes the article to a mail receptacle corresponding to the mail stop code.

Abstract: A window shade comprising a plurality of collapsible shade rows. Each of the shade rows being adjustable from a closed state to an opened state by an operating mechanism, and including a stiff first transverse region and an opposed second transverse region having a stiffened edge portion. When in the closed state, the window covering includes no or minimal gaps between the rows so that light is substantially or completely blocked. Also, the securement and opening members are also concealed from view when observed from the front or face of the window covering. The operating mechanism causes the narrowing of the rows by drawing the first transverse region and the opposed second transverse region closer together. The operating mechanism further causes the rows to be pivotally rotated to further widen opening in the window covering.
