  • Publication number: 20250071300
    Abstract: Embodiments of the present application provide a video transcoding method, a video display method, an apparatus and an electronic device, which relate to the field of video processing technology. The video transcoding method includes: acquiring a first image in an initial images obtained by stitching multi-channel video images; determining an initial resolution of each of initial sub-images; wherein each initial resolution is not greater than a maximum resolution of input data that can be supported by a preset encoder, and a target resolution of a target sub-image obtained after transcoding each initial sub-image is not greater than a maximum resolution of output data that can be supported by the preset encoder; segmenting a to-be-cut image into respective initial sub-images based on the respective initial resolutions; encoding each initial sub-image according to a target resolution of a target sub-image after transcoding this initial sub-image by using a preset encoder, to obtain each of target code-streams.

  • Publication number: 20240097888
    Abstract: In a file sharing system, a key manager unit realizes a correspondence between the first user identifier and the first public key in response to a registration request of the first user, generates a first key material for encrypting the first file into a first encrypted file, and generates a first credential according to the first user identifier, the first file identifier, the first public key and the first key material after receiving an access-right claim request to the first file from the first user. A file storage unit stores the first encrypted file and the first credential. The first user uses the first user identifier, the first file identifier and the first private key to retrieve the first key material out of the first credential, and uses the first key material to decrypt the first encrypted file into the first file.

  • Publication number: 20220213176
    Abstract: The present disclosure provides human antibodies and fragments thereof having binding specificity to the SARS-CoV-2 spike protein's receptor binding domain (RBD). The antibodies and fragments have strong affinity and potent neutralization ability against the SARS-CoV-2 virus and various mutant forms. Also provided are trimeric antibodies which have further enhanced neutralization capabilities. The antibodies and fragments thus may be used for preventing or treating SARS-CoV-2 viral infection or detecting the presence of the virus in a sample.

  • Publication number: 20170200159
    Abstract: A secure payment device having first and second modes is provided. In the second mode, a payment procedure is activated to receive data of a payment member for a secure payment. The secure payment device includes a touch screen group, a payment unit, a central processing unit and a secure microprocessor unit. The touch screen group displays an operation interface and a secure payment interface. In the first mode, the operation interface receives a first operation instruction via the operation interface. In the second mode, the secure payment interface obtains the data of the payment member by the payment unit, receive the second operation instruction via the secure payment interface, and activate the payment function based on a comparing result of the authentication information and the data of the payment member. A secure payment method for the aforementioned secure payment device is also provided.

  • Publication number: 20100117818
    Abstract: A speed-reduction alert device comprises a speed-reduction alert unit installed below a gas pedal for detecting swinging operation of the gas pedal so as to transfer a swing signal outwards; a computer main frame connected to the speed-reduction alert unit for receiving the swinging signals and controlling the flash frequencies, flash periods and change of signals of a brake light in a first car to show a deceleration of the first car to a driver of a second car so that the driver of the second car will alert the deceleration of the first car. When the gas pedal is pressed downwards for acceleration, the computer main frame will determine that it is an accelerating signal and the brake light is not actuated; and when the gas pedal is released to move upwards for deceleration, the computer main frame will determine that it is a deceleration signal.

  • Patent number: 6860316
    Abstract: A material melting device of metal injection molding machine comprises a main feeding cylinder; a plurality of preheating feed cylinders parallel arranged at a lateral side of a main feeding cylinder of a metal injection molding machine; a plurality of material outlets formed at a side of each preheating feed cylinder. The material outlets are communicated to the main feeding cylinder through the guide tubes. Thereby, an inner side of the preheating feed cylinder is pre-heated so as to get preheated grains by adjusting the preheating screw rods in the preheating feed cylinder. Moreover, the preheating feed cylinders can be replaced by feeding funnels and the guide tubes are replaced by heating pipes.

  • Patent number: 6681837
    Abstract: An air releasing check structure of a metal injecting machine has a seat rod installed between a rear seat of a feeding screw rod and the extruding head at a front end of the front section. A periphery of the seat rod is enclosed by a check toggle. If the material to be ejected has bubbles so that it is not extruded effectively, the bubbles will flow to the exhausting grooves of the check toggle. Then the bubbles are drained out. Thereby, the bubbles in the material are vented out so that the material becomes dense. When the material becomes dense with high tension, the pressure of material will be greater than the force for buckling the elastic toggles so that the elastic toggles expand. As a result, the elastic toggle will further isolate the exhausting groove. Thereby, the material moves forwards to be ejected from the extruding head.
