Abstract: A high-strength and high-toughness Al—Cu series cast aluminum alloy, a preparation method therefor, and the use of same in wheel hub manufacturing. Chemical components of the high-strength and high-toughness Al—Cu series cast aluminum alloy comprise the following elements in percentage by mass: 4.6-5.3% of Cu, 0.45-0.55% of Mn, 0.42-0.55% of Mg, 0.15-0.25% of Ti, 0.05-0.15% of Zr, and 0.003-0.011% of B; the chemical components of the high-strength and high-toughness Al—Cu series cast aluminum alloy further comprising Fe and Si in percentage by mass, 0.03<Fe?0.2%, the mass ratio of Fe:Si being (2-6):1, and the balance being Al and inevitable impurities. The high-strength and high-toughness Al—Cu series cast aluminum alloy has low cost, satisfies the market requirements on aluminum alloy parts such as vehicle wheel hubs, and therefore is of important significance in accelerating weight reduction of vehicles and achieving the objects of energy conservation and emission reduction.

Abstract: A method for calibrating a micro-electro-mechanical system (MEMS) gyroscopes by determining a plurality of variates including quadrature and inphase values from output data of a first subset of the MEMS gyroscopes, determining offset temperature coefficients of the first subset of the MEMS gyroscopes over temperature variation, computing a linear regression using the quadrature and inphase values and the offset temperature coefficients to determine linear regression variate coefficients for predicting the offset temperature coefficient based on the quadrature and inphase values.

Abstract: Aspects of the disclosure provide methods and apparatuses for video processing. In some examples, an apparatus for video processing includes processing circuitry. The processing circuitry determines gating weights associated with expert modules based at least partially on a quantization parameter (QP) value. The expert modules are configured to process an input block that includes an image block being reconstructed based on the QP value. The processing circuitry then weights the expert modules based on the gating weights to generate an output image block corresponding to the image block.

Abstract: A linear actuator includes a back fixture formed of a first part, a second part, and a plastic bearing, the first part connecting with the second part, grooves are disposed inside the first part and the second part, and extra structures are disposed outside the plastic bearing. The plastic bearing is secured inside the first part and the second part with the grooves and extra structures. The back fixture can be directly fitted onto a bed frame by applying a certain force to make an elastic deformation of this back fixture, thereby accelerating the installation of the actuator. This not only significantly reduces the noise caused by the connecting portion during the operation of the actuator, but also reduces the wearing of connecting parts, thereby significantly extending maintenance-free life.
