Abstract: A method, sensor, and non-transitory computer-readable storage medium are provided for estimating actual amplitudes of a waveform. A machine learning model may be trained for an embedded system of a first three-axes sensor having a limited range to estimate the actual amplitudes of a waveform that saturates the first three-axes sensor in a direction of one of the three axes. The embedded system acquires a second waveform during use of a tool including the first three-axes sensor. The second waveform that occurs after a second waveform producing event is isolated. The embedded system extracts a multi-dimensional feature from the isolated second waveform and estimates, using the machine learning model, the actual amplitudes of the second waveform based on the extracted multi-dimensional feature.

Abstract: A downhole tool includes a radiation generator configured to output radiation using electrical power received from a power supply. A first portion of the radiation is emitted into a surrounding sub-surface formation. The downhole tool also includes a radiation detector coupled proximate the radiation generator. The radiation detector includes a micromesh gaseous detector, and the radiation detector is configured to output a measurement signal based at least in part on interaction between a second portion of the radiation output by the radiation generator and the radiation detector. Additionally, the downhole tool includes a control system communicatively coupled to the radiation generator and the radiation detector. The control system is configured to determine measured characteristics of the radiation output from the radiation generator based at least in part on the measurement signal and to control operation of the radiation generator based at least in part on the measured characteristics.

Abstract: This disclosure is related to a downhole tool to be lowered into a wellbore, having a longitudinal axis and an outer surface, the tool including: a particle detection assembly having at least one particle detector for detecting at least a predetermined type of particles, wherein the particle detectors of the assembly are each wrapped around at least one detecting portion forming an angular portion of the tool azimuthal plane perpendicular to the longitudinal axis of the tool so that the detection assembly substantially forms a ring, at least a window transparent to the particle type and extending between the outer surface and the particle detection assembly.

Abstract: A requirement capture device for a centralized maintenance system for aircraft is composed of a means for capturing and parametrizing the various characteristics of the centralized maintenance system. It allows the various parties to the fine tuning of the CMS system to define the data set specific to their domain in a common framework. User profiles are defined for each of the users affording them configuration possibilities specific to their domain. After validation of the parameters input, a configuration file is generated.
