Abstract: Ce procédé d'analyse de signaux sismiques, à utiliser de concert avec une acquisition de données sismiques marines, consiste à détecter un signal fantôme de récepteur à l'aide d'un capteur acoustique immergé (18), puis à estimer la hauteur de la colonne d'eau au-dessus de ce capteur acoustique et ce, en utilisant le signal fantôme de récepteur (30). Le procédé peut, de surcroît, comporter les opérations suivantes : identification des modifications survenues en matière de temps d'arrivée des signaux sismiques reçus par plusieurs capteurs acoustiques immergés (18) et décalés dans l'espace par rapport à une source acoustique, détermination des différences temporelles entre les modifications susmentionnées identifiées et les modifications de temps d'arrivée escomptées en association avec un profil de profondeur théorique de capteur acoustique et conversion des différences temporelles en différences de profondeur entre le profil de profondeur théorique et le profil de profondeur réelle des capteurs acoustiques. Ce procédé, qui permet une meilleur détermination des hauteurs de vagues locales ainsi que de la profondeur du capteur acoustique, permet également d'atténuer, lors d'un traitement de données ultérieur, le <= bruit >= dans des données sismiques associées à des modifications de hauteurs de vagues locales et de profondeur de capteur sismique.

Title: Method and apparatus for automatically generating advisory information for pharmacy patients
Inventor: BYERLY BAXTER HAYES JR
IPC: G06Q30/00
Filed: 1999-01-21
Abstract: A system for generating targeted advisory messages for pharmacy patients bas ed on selected monitored data components of each transaction. When a pharmacy computer prints transaction data, the system monitors the data using printer  data capture hardware interposed between the pharmacy computer and its printer. An additional processor compares selected components of the monitor ed transaction data with preselected combinations of these components in a database. The database associates the preselected combinations of transactio n data components with advisory message components retrieved from the database  and used to build an advisory message for output to a printer, which may be the pharmacy computer or an additional printer. Targeting of the advisory messages is based on selected combinations of the identity of the drug being  dispensed to the patient, the patient's age and gender, the new or renewal status of the prescription, and the identity of the party primarily responsible for payment to the pharmacy for the transaction.

Title: Improved method for determining subscriber loop make-up
Inventor: GALLI STEFANO
IPC: H04L1/24
Filed: 2000-09-29
Abstract: A method and circuitry for comparing simulations of a subscriber loop to acquired waveforms. The method consists of analyzing the echo responses generated by the transmittal of pulses onto the subscriber loop. A slowly decaying signal caused by the inductive effect is removed from the echo signal. A simulated waveform is compared to the actual echo signal. By the method a discontinuity is identified in the frequency domain, the time domain signal representing each discontinuity is then obtained via an inverse fast Fourier transform and subtracted from the acquired data. The remaining data is then processed similarly as the method moves from the first discontinuity located nearest to a detector to the last discontinuity located farthest from the detector. The circuitry consists of an arrangement for calculating the difference between the responses on two branches of the loop. By use of this differential probing circuitry the echo response is captured and used in determining gauge and discontinuities.
