Abstract: A method for calibrating an electronic sensor for peening intensity. A range of desired intensity levels is chosen and that range may contain a single value or multiple values. The parameters for a blast stream are set that correspond to a particular intensity level. Test strips are peened in the blast stream and then the arcs of the peened strips are measured to determine the intensity level of the blast stream. Subsequently, a sensor is placed in the blast stream set at particular intensity levels and the signal generated at each intensity level is recorded. A roto-flap peening device can also be set at particular intensity levels and then a sensor is subjected to the roto-flap peening device set at those levels. A chart may be developed that correlates peening intensity to the signal of the sensor so the sensor may be used in place of Almen strips.

Abstract: Systems, methods, and computer-readable media for in-situ calibration of magnetic field measurements. In some examples, a method can involve generating a magnetic field via a magnetic field source that is coupled to a downhole tool. The magnetic field source can be located within a fixed distance from one or more sensors coupled to the downhole tool. The method can also involve obtaining respective field measurements of the known magnetic field from the one or more sensors, and comparing the respective field measurements from the one or more sensors with respective reference measurements previously obtained from the one or more sensors to yield respective comparisons. The method can then involve determining, based on the respective comparisons, a respective sensitivity drift for each of the one or more sensors.

Abstract: An animal trap system includes a glue board, an animal trap accelerometer sensor, and a signal unit in close proximity to and in communications with the animal trap accelerometer sensor, wherein the signal unit also contains an accelerometer sensor. The animal trap system is capable of detecting capture events, non-capture events, false positives, and/or the type of animal captured by using differential signal analysis and machine learning techniques. When an acceleration is received by the animal trap accelerometer sensor above a pre-set acceleration threshold value, it sends a capture signal to the signal unit and if the signal unit does not receive such acceleration event, the signal unit transmits a capture signal to an off-site receiver. A method of trapping one or more animals using this system is also provided.

Abstract: The accuracy of directional surveys may be improved using accelerometers, magnetometers, or both. A control system containing accelerometers is configured specifically to correct errors in bias and gain of each accelerometer by requiring the measured field strengths to be as constant as possible over several tool face angles over multiple points in a wellbore, even when all measurements are within a tangent or lateral section of a wellbore. Corrections for the bias and gain errors determined based on one or more measurements from the accelerometers are applied to measurements at other survey points to improve the accuracy of surveys and the efficiency of drilling operations.
