摘要： A method includes monitoring a submerged arc welding (SAW) operation in real-time; determining, based on the monitoring and in real-time, a discrepancy between a desired weld parameter and an actual weld parameter of a weld resulting from the SAW operation; and in response to determining the discrepancy, controlling a power supply, which provides power for the SAW operation, to modify at least one of balance or offset of an alternating current (AC) welding power signal supplied for the SAW operation to compensate for the discrepancy.

摘要： A method for measuring a characteristic of a thin film is disclosed. The method includes a) obtaining a measured spectrum from a target region on the substrate by using a spectroscopic ellipsometer, b) obtaining a physical model capable of obtaining an estimated parameter value related to the characteristic of the thin film through regression analysis of the measured spectrum, c) obtaining a machine learning model capable of obtaining a reference parameter value related to the characteristic of the thin film by using the measured spectrum, and d) obtaining an integrated model which uses an integrated error function capable of considering both of a first error function and a second error function, and obtaining an optimum parameter value through regression analysis of the integrated model.

摘要： Embodiments relate to predicting height information for an object. First distance data is determined at a first time when an object is at a first position that is only partially within the field-of-view. Second distance data is determined at a second, later time when the object is at a second, different position that is only partially within the field-of-view. A distance measurement model that models a physical parameter of the object within the field-of-view is determined for the object based on the first and second distance data. Third distance data indicative of an estimated distance to the object prior to the object being entirely within the field-of-view of the distance sensing device is determined based on the first distance data, the second distance data, and the distance measurement model. Data indicative of a height of the object is determined based on the third distance data.

摘要： A gel-time detection apparatus includes a carrier, a stirring device, and an image-capturing device. The gel-time detection apparatus uses the carrier to liquefied powder to be detected, uses the stirring device to stir the liquefied powder and sense the torque of stirring the liquefied powder, and uses the image-capturing device to capture images of the liquefied powder, so as to determine a gel time according to a determination criterion relevant to the torque and the images. A gel-time detection method includes liquefying powder to be detected, stirring the powder, sensing the torque of stirring the liquefied powder, capturing images of the liquefied powder, and then determining a gel time according to a determination criterion relevant to the torque and the images. The determination criterion may include a torque predetermined threshold and an area-shrinkage-rate predetermined threshold.

摘要： A substrate inspection system is provided to monitor characteristics of a substrate, while the substrate is disposed within (or being transferred into/out of) a processing unit of a liquid dispense substrate processing system. The inspection system is integrated within a liquid dispense substrate processing system and includes one or more optical sensors of a reflectometer (such as a spectrometer or laser-based transceiver) configured to obtain spectral data from a substrate. A controller is coupled to receive the spectral data from the optical sensors(s). The one or more optical sensors (or one or more optical fibers coupled to the rest of the optical sensor hardware) are coupled at locations within the substrate processing system. The controller analyzes the spectral data received from the optical sensors(s) to detect characteristic(s) of the substrate including, but not limited to, film thickness (FT), refractive index changes, and associated critical dimension (CD) changes.

摘要： A system and a method are disclosed including a dual laser measurement device (DLMD) coupled with a mobile computing device to measure dimensions of a building or other structure, calculate other quantities based on the measured dimensions, select building construction or finishing material, order the material, and save the list of the measured dimensions and ordered materials in a data storage device. All steps of this process from measurement to ordering material may be performed using a DLMD app running on the mobile computing device.

摘要： Dimensions of a surface feature are determined by capturing an image of the surface feature and determining a scale associated with the image. Structured light may be projected onto the surface, such that the position of structured light in the captured image allows determination of scale. A non-planar surface may be unwrapped. The surface may alternatively be projected into a plane to correct for the scene being tilted with respect to the camera axis. A border of the surface feature may be input manually by a user. An apparatus and system for implementing the method are also disclosed.

摘要： A method for performing a formation-related physical action includes: receiving image data of a wall of a borehole penetrating a formation, the image data having image data of fractures intersecting the wall of the borehole; and defining a volume surrounding the borehole. The method also includes determining a surface area of each fracture intersecting the volume at each defined depth in a plurality of depths and calculating a fracture density for each defined depth based on the surface area of each fracture intersecting the volume at each defined depth in a plurality of depths and a size of the volume. The method further includes performing the formation-related physical action based on the fracture density for each defined depth using apparatus configured to perform the formation-related physical action.
