Publication number: 20240072696Abstract: A computer-implemented method of monitoring and/or controlling an electro-mechanical device, such as an electrical motor and/or generator, includes determining a first probability distribution of a virtual measurement variable, such as temperature at a predetermined position, of the electro-mechanical device. A confidence level is determined for a first value of the virtual measurement variable based on the first probability distribution. An operating mode of the electro-mechanical device is changed based on the confidence level, and/or an indication is displayed on a display. The indication instructs a user to change the operating mode of the electro-mechanical device.Type: ApplicationFiled: August 29, 2023Publication date: February 29, 2024Inventors: Vincent Malik, Mohamed Khalil, Christoph Ernst Ludwig, Dimitrios Loukrezis, Dominik Zacharias, Matthias Erlwein, Christian Andreas Wolf Pozzo

Patent number: 11665806Abstract: The present disclosure relates to a downhole tool that includes a first photon flux detector disposed at a first radial position about a longitudinal axis of the downhole tool that measures a first signal indicative of an x-ray flux of the x-ray photons. The downhole tool also includes a second photon flux detector disposed at a second radial position about the longitudinal axis of the downhole tool that measures a second signal indicative of the x-ray flux of the x-ray photons. Further, the downhole tool includes a controller communicatively coupled to the first photon flux detector and the second photon flux detector that determines a condition associated with the electron beam based at least in part on a relative x-ray flux from the first photon flux detector and the second photon flux detector.Type: GrantFiled: December 20, 2019Date of Patent: May 30, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jani Reijonen, Vincent Ernst

Patent number: 9840623Abstract: A detoxification method for obtaining a pigment compound free from acute and chronic aquatic ecotoxicity by mixing at least one zinc-based component with good anti-corrosive properties but high toxicity-with a phosphate or hydrogen phosphate of a magnesium, sodium, potassium, calcium, strontium, aluminum, ammonium, or organic type or any other compound based on such cations, such as carbonates, oxides, silicates, phosphites, pyrophosphates or phosphonates, said phosphates or hydrogen carbonates or carbonates or oxides or silicates or phosphites or pyrophosphates freed from toxicity enabling a very considerable reduction of the toxic power of said zinc-based component, while maintaining the good anti-corrosive properties thereof.Type: GrantFiled: February 19, 2010Date of Patent: December 12, 2017Assignee: Societe Nouvelle Des Couleurs ZinciquesInventors: Christelle Berteloot, Vincent Ernst, Ludovic Mavel

Patent number: 9143026Abstract: A method for regulating output of a high voltage generator includes monitoring a voltage output of the generator and comparing it to a voltage setpoint to generate an error signal. A load on the generator is monitored to generate a load signal. The load signal is conducted to a feedforward signal generator. The feedforward signal generator is configured to produce a feedforward signal corresponding to the load and to at least one parameter related to an output impedance of the high voltage generator. The error signal is conducted to a high voltage regulation loop. The control loop output and the feedforward signal generator output are coupled to a driver for the high voltage generator.Type: GrantFiled: March 6, 2014Date of Patent: September 22, 2015Assignee: Schlumberger Technology CorporationInventors: Kevin L. Hiles, Robert A. Adolph, Jacques Jundt, Vincent Ernst

Patent number: 8258724Abstract: A tunable LC circuit is used to trigger an electron discharge from an accelerator device, such as a Betatron. The circuit includes a coil as a first inductor having a first inductance electrically coupled in series with a capacitor. A second inductor having a variable inductance is electrically coupled, either in series or parallel, to the first inductor. The time to capacitor discharge is governed by: ?LC=?{square root over ((L+LTUNE)C)}. Adjusting the inductance of the variable inductor (LTUNE) facilitates continuous adjustment of the discharge time. This is particularly useful when the LC values change in response to external stimuli, such as borehole temperature when a Betatron is used to log borehole features.Type: GrantFiled: September 12, 2007Date of Patent: September 4, 2012Assignee: Schlumberger Technology CorporationInventor: Vincent Ernst

Patent number: 7928672Abstract: Described herein is a modulator circuit for generating discrete energy pulses in a device. The circuit includes a high voltage power source intermittently coupled to a saturable first inductor, a second inductor and a capacitor coupled in parallel between the high voltage power source and the saturable first inductor and second inductor. When the first inductor is unsaturated, its inductance is high and it isolates the capacitor from the second inductor. When the first inductor saturates, the inductance collapses and the capacitor discharges a high energy pulse into the second coil. By controlling the time to saturation, the timing of the pulses is controlled. The modulator circuit is effective to control pulses applied to a circular induction accelerator, such as a Betatron.Type: GrantFiled: September 19, 2007Date of Patent: April 19, 2011Assignee: Schlumberger Technology CorporationInventor: Vincent Ernst
