Abstract: A data transmission method, and a related apparatus, are provided. The method include: determining, by a first controller in available transit switches in a data center network, available transit switches respectively transiting m groups of data, where one available transit switch is configured to transit at least one group of the data, and a difference between quantities of groups of the data transited by any two available transit switches does not exceed a second threshold; and instructing, by the first controller, a destination network node to send routing information to the source network node, where the routing information includes an identifier of an available transit switch configured to transit a data group transmitted by the source network node to the destination network node. The foregoing solution can balance load of each transit switch in the data center network, improve a bandwidth resource utilization rate, and reduce a transmission delay.

Abstract: A hearing-aid audio control method and system are disclosed. The method includes the steps of obtaining a hearing compensation curve of a hearing-impaired person in advance; receiving and obtaining an original audio signal; using the hearing compensation curve to perform power compensation on a corresponding frequency band of the original audio signal to obtain a hearing-aid audio signal; outputting the hearing-aid audio signal and/or using the hearing-aid audio signal to drive operation of an audio system. The method can use the hearing compensation curve of the hearing-impaired person to perform power compensation on the corresponding frequency band of the original audio signal to obtain the hearing-aid audio signal. By adjusting the volume of the corresponding audio frequency bands, the hearing-impaired can hear the sound clearly, without continuous hearing loss due to excessive volume adjustment and without disturbing other people.

Abstract: A movable camera travels along an inspection path for optically inspecting an inspection surface of an object for defect detection. In planning the inspection path, a set of viewpoints on the inspection surface is generated. Each viewpoint is associated with a patch, which is a largest area of the inspection surface within a field of view (FOV) of the camera when the camera is located over the viewpoint for capturing an image of FOV. An effective region of the patch is advantageously predicted by a neural network according to a three-dimensional geometric characterization of the patch such that the predicted effective region is valid for defect detection based on the captured image. A valid area is one whose corresponding area on the captured image is not blurred and is neither underexposed nor overexposed. The inspection path is determined according to respective effective regions associated with the set of viewpoints.

Abstract: An adaptive approach to image bracket determination and a more memory-efficient approach to image fusion, which are designed to generate low noise and high dynamic range (HDR) images in a wide variety of capturing conditions, are described. An incoming preview image stream may be obtained from an image capture device. When a capture request is received, an analysis may be performed on an image from the preview image stream that has a predetermined temporal relationship to the image capture request. Based on the analysis, a set of images (and their respective capture parameters, e.g., exposure time) may be determined for the image capture device to capture. As the determined set of images are captured, they may be registered and fused in a memory-efficient manner that, e.g., places an upper limit on the overall memory footprint of the registration and fusion operations—regardless of how many images are captured in total.

Abstract: Methods, systems, and devices for techniques to manufacture inter-layer vias are described. In some examples, a manufacturing process for a via to one or more metal lines within an integrated circuit may not include forming a metal pad for the via. For example, the manufacturing process may include forming a layer of dielectric material over a set of metal lines. The manufacturing process may further include forming a cavity through the dielectric layer (e.g., using an etching procedure), exposing the upper surfaces and sidewalls of one or more metal lines of the set. Subsequently, the via may be formed by depositing a conductive material within the cavity. In some cases, the conductive material may be deposited to contact the sidewalls of the one or more metal lines. Such an assembly may establish electrical connection to other electrical components of the integrated circuit.

Abstract: Devices, methods, and computer-readable media are disclosed describing an adaptive approach for image bracket selection and fusion, e.g., to generate low noise and high dynamic range (HDR) images in a wide variety of capturing conditions. An incoming image stream may be obtained from an image capture device, wherein the incoming image stream comprises a variety of differently-exposed captures, e.g., EV0 images, EV? images, EV+ images, long exposure (or synthetic long exposure) images, EV0/EV? image pairs, etc., which are received according to a particular pattern. When a capture request is received, a set of rules and/or a decision tree may be used to evaluate one or more capture conditions associated with the images from the incoming image stream and determine which two or more images to select for a fusion operation. A noise reduction process may optionally be performed on the selected images before (or after) the registration and fusion operations.
