摘要： A precipitation shield device, and/or methods of manufacturing and/or using the shield device are provided. The shield device of embodiments includes functionality to prevent accumulation of precipitation over an imaging sensor. In embodiments, the shield device includes a base that enables the shield device to be mounted onto an imaging sensor. A shield body may be defined by two end walls and two lateral walls disposed around a central opening of the shield body. During operation, the central opening is aligned with a window of the imaging sensor. In embodiments, the end walls may have a surface configured to control an airflow flowing over the shield device to create a vortex over the central opening of the shield device. In embodiments, the vortex created over the central opening may deflect precipitation away from the central opening and may prevent the precipitation from accumulating over the window of the imaging sensor.

摘要： In one embodiment, a method includes receiving, by a defect detector module, an image of a physical object and classifying, by the defect detector module, one or more first features from the image of the physical object into one or more first classifications using one or more machine learning algorithms. The method further includes analyzing, by the defect detector module, the one or more first classifications and determining, by the defect detector module, that the physical object comprises a defect based on analyzing the one or more first classifications.

摘要： A pyro-metallurgical process for producing a non-ferrous metal or a compound thereof, wherein a metal raw material is fed into a rotary kiln, the metal being one of arsenic (As), antimony (Sb), lead (Pb), cadmium (Cd), mercury (Hg), silver (Ag), tin (Sn), nickel (Ni), or zinc (Zn). The raw material is heated to produce a volatized material, in which the non-ferrous metal or compound thereof is produced from the volatized material. A magnesium-based additive is additionally fed to the rotary kiln in an amount of between 0.5 wt. % and 9.5 wt. % relative to the total weight of the raw material. The magnesium-based additive is heated together with the raw material to produce the volatized material and a solid product while also counteracting ring formation in the rotary kiln.

摘要： A sample confinement tool includes a first end and a second end. The first end of the sample confinement tool is coupled to a driving tool. The driving tool is coupled to a heavy-duty vehicle. The sample confinement tool is operable to insert a predetermined depth below a ballast surface and collect a ballast sample within the second end of the sample confinement tool. The sample confinement tool is also operable to confine the ballast sample within the second end of the sample confinement tool by mechanically compressing the ballast sample. The sample confinement tool is further operable to release the ballast sample into a sample receptacle by mechanically decompressing the ballast sample.

摘要： A removable passive airflow oscillation device can be disposed within a pressurized wing structure utilized as a plenum. The passive airflow oscillation device can be a removable insert disposed into exterior vehicle surfaces with pressurization of a sealed chamber to provide the airflow. The device can include a cavity configured to receive the airflow from an ingress opening, direct the airflow therethrough to generate a predetermined oscillating airflow, and expel the oscillatory airflow from the egress opening. The removable passive airflow oscillation devices can provide quick and simple replacement and maintenance of damaged or clogged devices. The aft chamber of the flap seal can be sealed and pressurized to serve as a plenum providing the airflow to the actuators. The device can receive airflow, such as compressor air, and expel an oscillating airflow. Because each device is self-contained the number of devices and location thereof can vary by application.

摘要： A process for manufacturing a slag conditioning agent for steel desulfurization is shown in which a dried slag material Obtained from a secondary steelmaking process is mixed with quicklime particles. The quicklime particles react with moisture in the slag material to dry the slag material and produce a blend of slag material, hydrated lime and any unreacted quicklime. The blend is then sieved to separate out the hydrated lime. The retained dried fraction after sieving is then mixed with an Al2O3 mass fraction from which the slag conditioning agent can be collected. The slag conditioning agent has an equivalent mass ratio which is between 0.55 and 1.5.

摘要： An on-board thermal track misalignment detection system method therefor is presented. The system can use on-board locomotive sensors attached to an end-of-train device to detect (on the edge), signs and symptoms of thermal misalignments of the track. Once detected an alert can be transmitted to prevent potential derailments. The system can also include a forward-facing and rearward-facing imaging sensors (e.g., camera, LiDAR sensor, etc). The system can wirelessly communicate (e.g., via radio) with a leading locomotive to ensure proper air pressure and location. The system can be powered by an on-board battery and/or air pressure device. Advantageously, the system can calculate whether any rail deviation is significant (e.g., via one or more threshold values). The system can also leverage image processing functionality, executed by one or more processors) to find the centerline and the distance between the tracks.

摘要： In one embodiment, a method includes capturing, by a camera of an image capturing module, a first image of a target. The image capturing module and a drum are attached to a fixture and the target is attached to the drum. The method also includes determining a number of lateral pixels in a lateral pitch distance of the image of the target, determining a lateral object pixel size based on the number of lateral pixels, and determining a drum encoder rate based on the lateral object pixel size. The drum encoder rate is programmed into a drum encoder. The method further includes capturing, by the camera, a second image of the target while the target is rotated about an axis of the drum, determining a number of longitudinal pixels in a longitudinal pitch distance of the second image, and comparing the number of lateral pixels to the number of longitudinal pixels.

摘要： A rail vehicle includes a truck having wheels for engaging a railroad track, a bolster supported by the truck, and a tank supported by the bolster for storing a lading. A measurement system measures the level of the lading within the tank and includes gauges and a controller. The gauges are disposed at selected points on the bolster for sensing at least one of lateral and longitudinal localized displacement experienced by the bolster during motion of the rail vehicle. The controller calculates the level of the lading within the tank and compensates for changes in the level of the lading during motion of the rail vehicle in response to signals generated by the gauges.
