Abstract: Disclosed is a fundus camera, which relates to the technical field of medical devices and includes: an illumination module, a main optical assembly, a focusing module, and an image sensing acquisition module; the illumination module includes a plurality of light sources configured to emit light of different wavelengths, illumination light emitted by the plurality of light sources is conducted to enter an eye of a patient through the main optical assembly, and light reflected by a retina of the patient is conducted to pass through the main optical assembly and the focusing module to enter the image sensing acquisition module. The fundus camera provided by the present application improves the technical problem that the fundus camera in the prior art cannot image different layers of the retina, thereby providing valuable medical and diagnostic data.

Abstract: This application discloses a task processing method, a system, a device, and a storage medium. The method includes: receiving a task published by a task publisher device and an electronic resource allocated for execution of the task; transmitting the task and the electronic resource to a blockchain network, to enable the blockchain network to construct a smart contract corresponding to the task and the electronic resource; transmitting the task to a task invitee device, to enable the task invitee device to execute the task; receiving an execution result corresponding to the task transmitted by a task invitee device after the task invitee device executes the task; and transmitting the execution result to the blockchain network, to enable the blockchain network to perform verification on the execution result according to the smart contract, and transfer the electronic resource to the task invitee device according to a verification result.

Abstract: A method and an apparatus for repairing a system file are provided. The computer-implemented method for repairing a system file, comprises: detecting, by a processor, a corrupted system file in an operating system; sending identification information of the operating system and an identifier of the corrupted system file to a server; receiving an integrity identifier of an intact system file to be used in repairing the corrupted system file, wherein the intact system file is determined by the server according to the identification information of the operating system and the identifier of the corrupted system file; verifying, by the processor, the received integrity identifier with a locally stored integrity identifier of the corrupted system file; and if the received integrity identifier passes the verification, obtaining, from the server, the intact system file corresponding to the verified integrity identifier and repairing the corrupted system file with the obtained intact system file.

Abstract: The present disclosure, pertaining to the field of data processing technologies, discloses a file opening method, apparatus, and terminal. The method includes: capturing a file opening action, and acquiring a corresponding original file system device object and a corresponding original file system distribution function address; and directly sending a file opening request to a file system where the original file system device object is located, transferring the file opening request over the file system to an original file system distribution function corresponding to the original file system distribution function address, and performing a file opening operation by using the original file system distribution function. According to the present disclosure, a file opening request is directly sent to a file system where an original file system device object is located, and a file opening operation is performed by using an original file system distribution function.
