  • Patent number: 11936909
    Abstract: A prediction method, an encoder, a decoder, and a computer storage medium are provided. The prediction method applied to an encoder includes: determining a spatial block in which an encoding point is located; constructing a prediction model according to the spatial block; acquiring a value of a first colour component and a value of a second colour component of the encoding point; obtaining a prediction value of the second colour component of the encoding point by using the prediction model and the value of the first colour component; calculating a difference between the value of the second colour component and the prediction value of the second colour component, and using the obtained difference as a residual of the encoding point; and performing Level of Detail (LOD) partitioning and lifting transform based on the residual of the encoding point.

  • Publication number: 20230018817
    Abstract: A single-stage enthalpy enhancing rotary compressor and an air conditioner having same. The single-stage enthalpy enhancing rotary compressor includes: at least one single-stage cylinder, a rotator, an upper flange, and a lower flange. The rotator is arranged inside the cylinder and is rotatable, a compression chamber is formed between the rotator and an inner peripheral wall of the cylinder, a vapor injection opening is defined in at least one of the upper flange the lower flange, and the vapor injection opening is configured to supply gas outside the compressor to the compression chamber directly. According to the present disclosure, two-stage compression is realized without adding an extra cylinder, thereby effectively enhancing a circulation of refrigerant, improving cooling performance of the air conditioner under high environmental temperatures.

  • Patent number: 10651646
    Abstract: A fault current limiter, including: two inductors, a direct current circuit breaker, a shunt resistor, a first fixed resistor, and metal oxide arresters. The two inductors include wound superconducting wires. The inductors have identical number of windings and identical structure. Magnetic fluxes of the inductors are forward coupled, and the inductors are connected in parallel to form a superconducting inductor structure. The direct current circuit breaker and the superconducting inductor structure are connected in series to form a series branch. The shunt resistor is connected in parallel to the series branch. The first fixed resistor is connected in parallel to the direct current circuit breaker. The metal oxide arresters are two in number, and are connected to two ends of the inductors in parallel.
