  • Patent number: 11932293
    Abstract: A car monitoring system includes: a sub-system to execute a predetermined function by controlling at least one instrument mounted on a railcar; and a monitoring device to monitor an operating state of the sub-system. The sub-system includes: a sub-system controller to create status data containing pieces of event information based on a signal output from the instrument and periodically transmit the status data to the monitoring device, the information informing the monitoring device of a change in state of the instrument; and a first memory to store a first event parameter file defines a data structure of an event region of the status data, the event region being a region wherein the information are stored. When the first parameter file is changed, and the sub-system controller creates the status data, the controller reconstructs the data structure of the region and resets the information in accordance with the reconstructed data structure.

  • Patent number: 11625886
    Abstract: A non-transitory computer-readable storage medium storing a set of program instructions for an image generating apparatus is disclosed. The set of program instructions, when executed by a controller of the image generating apparatus, causes the image generating apparatus to perform: acquiring input image data; and executing a style transfer process on the input image data by using a trained machine learning model, thereby generating transferred image data. The machine learning model is trained by using a plurality of data pairs each including content image data and style image data corresponding to the content image data. The style image data is generated by executing particular image processing on the corresponding content image data. The particular image processing is a process of applying a particular style to a content image indicated by the content image data.

  • Patent number: 11107210
    Abstract: In an image data generating apparatus, an image processor acquires target output image data converted from target input image data by a pre-trained model. The target input image data represents a captured image of a target product. The target output image data represents an image of a target product free from defects. The pre-trained model performs data compression and data decompression on inputted image data. The image processor generates first data by performing a first generation process on the target input image data. The first generation process includes a luminosity adjustment process adjusting luminosity in image data. The image processor generates second data by performing a second generation process including the luminosity adjustment process on the target output image data. The image processor generates inspection image data by using a difference between the first data and the second data for inspecting an external appearance of the target product.

  • Patent number: 6829047
    Abstract: A defect detection system to check any defect in the pattern to be checked by comparing a pattern to be checked with a reference pattern includes an edge detection means for detecting a pattern edge of the pattern to be checked by scanning a substrate by laser beams and detecting reflected light thereof. After the relative position between the substrate and the imaging means is adjusted so that the pattern edge of the pattern to be checked is substantially aligned with one side of CCD pixels, an image of the pattern to be checked is picked up. Therefore, the defect detection system corrects misalignment less than one pixel between a pattern to be checked and a reference pattern to prevent occurrence of a false defect.

  • Patent number: 5205293
    Abstract: The present invention provides a method of measuring skin blood flow on a test site using a blood flow meter. The method includes the steps of calibrating the probe of the blood flow meter, using a bio-simulating model to produce a thermo-EMF flow curve, attaching the probe to a site to be tested to generate an electromagnetic force for the test site, and determining the skin blood flow at the test site by comparing the electromagnetic force to the thermo-EMF curve. The method may also include the step of maintaining the temperature in the probe at a value slightly higher than that of the test site.
