Abstract: A wafer defect detection method, after initiating electron-beam scanning of a target defect detection region of a to-be-detected wafer, obtains a wafer image of the to-be-detected wafer, calculates the image sharpness of the wafer image, and obtains a sharpness evaluation value of the wafer image based on the image sharpness of the wafer image, and when the sharpness evaluation value fails to meet the preset condition, which indicates that the quality of the obtained wafer image is poor, marks the defect detection result of the to-be-detected wafer as unreliable detection result, for distinguishing the defect detection result of the to-be-detected wafer with a good quality of the wafer image, thereby improving the reliability of the defect detection result of each to-be-detected wafer, and avoiding the use of wrong defect detection results in subsequent processes.

Abstract: A method for detecting an object includes obtaining an original image of a road through a sensor by performing an image capturing operation; extracting a region of interest (ROI) including a first target pixel point from the original image, in which the first target pixel point is a pixel point in the original image corresponding to a position on the road that is farthest from the sensor; and generating an object detection result by performing object detection on the ROI.

Abstract: In a method and an apparatus for controlling heating of a vehicle battery, the method includes: obtaining, by a receiver, an ambient temperature of a vehicle and battery output power; determining, by a controller, whether the ambient temperature is lower than a predetermined ambient temperature threshold; when it is determined that the ambient temperature is lower than the predetermined ambient temperature threshold, determining, by the controller, whether a battery heating setting is on; and when it is determined that the battery heating setting is on, controlling, by the controller, the heating of the vehicle battery so that the battery output power is between a first reference power and a second reference power.

Abstract: A blade noise reduction device, comprising a plurality of sawtooth units. The plurality of sawtooth units are arranged in a first direction. Each sawtooth unit comprises secondary teeth and a primary tooth, which extend in a second direction, wherein at least one secondary tooth is distributed on each of two sides of the primary tooth, the tooth vertex angle of the secondary tooth being smaller than the tooth vertex angle of the primary tooth. The blade noise reduction device can remarkably improve the noise reduction effect. In addition, the present invention further relates to a blade having the blade noise reduction device, and a wind turbine generator set having the blade.

Abstract: A method, an apparatus, and a storage medium are provided for ending video communication. The method includes: detecting whether a first end button is clicked by a user during the video communication between the electronic device and a counterpart device; sending network failure prompt information to a counterpart device when detecting that the user clicks the first end button; sending a disconnection request to the counterpart device to disconnect video communication with the counterpart device.

Abstract: An artificial cervical vertebrae composite joint is composed of two upper and lower fixing members disposed vertically symmetrically, a cervical vertebrae body member, and two connection members, the cervical vertebrae body member being connected between the fixing members through the connection members. The fixing members each have an L shape and comprise a front wing part and a base part. A locking screw hole is formed in the front wing part, and a skidproof groove provided with an inverted tooth and a protrusion is disposed on a middle portion of the base part. A bone grafting hole is transversely disposed through a middle portion of the cervical vertebrae body member, and two cavities are disposed on both upper and lower sides of the cervical vertebrae body member at an axial center of the cervical vertebrae body member to mount the connection members.
