The invention discloses a projection control method for karaoke sound equipment, the karaoke sound equipment comprises a first screen and a second screen, the first screen is a display screen, the second screen is a projection device.The method comprises the steps that after a system is started, projection control mode setting is obtained, the projection control mode comprises a default opening mode, a default closing mode or an automatic detection mode; when the projection control mode is an automatic detection mode, obtaining distance information in multiple directions in front of the projection device; judging whether a projection environment meeting a preset projection condition exists or not based on the distance information; when the judgment result meets the preset projection condition, controlling the second screen to be in an on state; and when the judgment result does not meet the preset projection condition, controlling the second screen to be in a closed state. The invention provides a projection control method for a karaoke sound box and the karaoke sound box, and solves the problem of poor starting and stopping experience of traditional projection.

This invention provides a method and apparatus for power consumption control of a satellite communication SoC chip. The method includes: real-time monitoring of the comprehensive operating parameters of each functional module, calculating power consumption requirements based on satellite orbital characteristics, generating power consumption control commands, performing intelligent clock gating and frequency adjustment operations on the functional modules, and ultimately achieving precise power consumption distribution control. This method can achieve real-time optimized power consumption management based on the dynamic changes of satellite communication services and the periodic characteristics of the orbit, effectively extending the satellite's on-orbit operational life and reducing the overall power consumption level.

The utility model relates to a three-axis micro-electro-mechanical gyroscope and a micro-electro-mechanical gyroscope. A microelectromechanical gyroscope includes a die of semiconductor material forming a substrate and a detection structure suspended over the substrate. The detection structure has a main extension in a horizontal plane, is symmetric with respect to the central symmetry axis, and is provided for each gyroscope detection axis with: a first pair of detection masses arranged on a first side of the central symmetry axis; and a second pair of proof masses arranged on a second side of the central symmetry axis, the second side being opposite to the first side in the horizontal plane. The proof masses in each pair are capacitively coupled to a respective stator electrode according to a differential detection scheme. The stator electrodes are symmetrically arranged on opposite sides of the central symmetry axis with respect to each other.
