Abstract: A button control circuit includes a button module, a power module, a control module, and a power supply control module. The button module is configured to simultaneously turn on a path between the power module and the control module and a button encoded signal trigger path when being operated. The control module is configured to start timing and output a first control signal to the power supply control module when obtaining a power signal in a power-off state. The first control signal is configured to control the power supply control module to be turned on, so as to supply power to the control module within a preset delay duration through the power module. The control module outputs a second control signal to the power supply control module when the button module is not operated within the preset delay duration.

Abstract: Embodiments of the present disclosure disclose an image compositing method and apparatus, used for harmoniously obtaining and displaying a simulation object composited with an accessory, so that a user has desirable experience and visual enjoyment. The apparatus obtains first data of a skeletal model of a simulation object and skeleton data of an accessory to be composited to the simulation object and determines, based on the first data and the skeleton data of the accessory, a target skeleton that is on the skeletal model and that corresponds to the accessory. The apparatus copies first target data of the target skeleton from the first data and adjusts the first target data of the target skeleton based on preconfigured offset data of the target skeleton to obtain first adjusted data. Finally the apparatus performs shading based on the first adjusted data and the first data to obtain the simulation object composited with the accessory.

Abstract: The present disclosure provides a method, User Equipment (UE) and base station for adjusting a Modulation and Coding Scheme (MCS). The method comprises: receiving, by a user equipment (UE), a first downlink data frame sent by a base station at a first moment, and estimating, by the UE, a first Signal to Interference and Noise Ratio (SINR) and a first Channel Quality Indicator (CQI) according to the first downlink data frame; estimating a second SINR and a second CQI according to a received second downlink data frame, wherein the second downlink data frame is sent by the base station at a second moment later than the first moment; calculating, by the UE, a MCS variation according to at least one of the first CQI, the second CQI, the first SINR or the second SINR; and feeding back, by the UE, the MCS variation to the base station.
