Abstract: A system for measuring brake data from a braking assembly of a vehicle. The braking assembly includes a floating portion that moves relative to brake pad wear. The system includes a brake sensor for each wheel. The brake sensors include a fixed sensing element and a target portion attached for movement with the floating portion. The sensing element generates a signal indicating a position of the target portion. The signal is used to determine brake pad thickness. The brake sensor also transmits the signal over a wireless vehicle area network for receipt and processing by a wireless hub in the vehicle area network. The vehicle area network can generate and transmit an alert and/or instructions for an autonomous vehicle based on the signal.

Abstract: In some implementations, a controller may receive, from a sensor system of the machine, sensor data indicating a movement of an idler block of an idler assembly of an undercarriage of the machine. The controller may determine, based on the sensor data, that the idler block has moved from a first position to a second position. The controller may determine an amount of wear of an idler of the idler assembly based on the idler block moving from the first position to the second position. The controller may determine whether the amount of wear satisfies a wear threshold. The controller may cause the machine to perform an action based on determining whether the amount of wear satisfies the wear threshold.

Abstract: A method of chemical mechanical polishing includes bringing a substrate having a conductive layer disposed over a semiconductor wafer into contact with a polishing pad, generating relative motion between the substrate and the polishing pad, monitoring the substrate with an in-situ electromagnetic induction monitoring system as the conductive layer is polished to generate a sequence of signal values that depend on a thickness of the conductive layer, determining a sequence of thickness values for the conductive layer based on the sequence of signal values, and at least partially compensating for a contribution of conductivity of the semiconductor wafer to the signal values.

Abstract: Apparatus and methods can be implemented to monitor the condition of the production and intermediate casing strings in oil and gas field operations. A series of measurements can be made in a multi-pipe structure and received responses can be operated on by employing a mapping optimization procedure in which a surrogate model is updated. Estimates of one or more properties of the pipes of the multi-pipe structure can be generated using coefficients of the updated surrogate model. Additional apparatus, systems, and methods are disclosed.

Abstract: Methods, systems, and computer program products for inspecting a pipe in a well using an eddy-current based pipe inspection tool comprises conveying the pipe inspection tool through the well, obtaining a first voltage measurement at an axial position along the pipe from at least one main receiver. The first voltage measurement includes a residual voltage induced in the at least one main receiver by a residual magnetic field resulting from residual magnetism in the pipe. A second voltage measurement is obtained at said axial position along the pipe from at least one second receiver. The first voltage measurement and the second voltage measurement are processed to obtain a processed measurement representing a difference between the first and second voltage measurements. The processed measurement is substantially free of the residual voltage and may be use to estimate a thickness of the pipe and other pipe characteristics.

Abstract: A method predicts an amount of wear that is expected to occur on the tubes of a steam generator as a result of vibration against another structure within the steam generator. The method includes determining a volumetric amount of material that has been worn from a location on a tube over a duration of time and employing that volume as a function of time to determine the volume of material of the tube wall that is predicted to be worn from the tube or another tube at a future time. The volumetric-based analysis enables more accurately prediction of the wear depth at a future time. This enables the plugging of only those tubes that are determined from a volumetric analysis to be in risk of breach at the future time, thus slowing the rate at which tubes of a steam generator will be plugged.

Abstract: This invention relates to the monitoring of the integrity of casing, tubing and other strings in oil and gas wells. The technical result of this invention consists in increased accuracy and trustworthiness in detecting and locating transverse and longitudinal defects in well completion components and downhole equipment, in both the magnetic and non-magnetic first, second and other metal barriers. Electromagnetic defectoscopy in multi-string wells includes measuring EMF induced in a coil by eddy currents generated in metal barriers by the decay of the electromagnetic field produced by magnetization current pulses in the coil. A series of pulses of fixed duration in the range of 0.1-1000 ms is fed to each exciter-and-pickup coil to sequentially magnetize all metal barriers starting from the nearest one, with pulse durations increasing for each next barrier. The recorded data are saved and processed by comparing them with model data, and the processing results indicate detects in the metal barriers. The downhole electromagnetic defectoscope contains a case, axially oriented coils with their magnetic axes coinciding with the tool's magnetic axis, and an electronic module, and at least two exciter-and-pickup coils, each consisting of an exciter coil and a pickup coil with a single core. The exciter-and-pickup coils are of different sizes and are spaced apart by a distance of not less than the length of the larger exciter-and-pickup coil.
