Abstract: A power supply assembly includes: a first mounting hole for mounting a magnetic member, an inner wall of the first mounting hole being provided with a vent groove; and an airflow sensor in air communication with the vent groove. In an embodiment, the power supply assembly is provided with a mounting groove and the airflow sensor is mounted in the mounting groove.

Abstract: A vaporizer includes: a first air outlet channel and a vaporization cavity that are in communication with each other; and a liquid guide member arranged on an end portion of the first air outlet channel that is close to the vaporization cavity, the liquid guide member being in contact with condensate falling off from the first air outlet channel so as to destroy surface tension of the condensate through a downward pulling force, and guiding the condensate into the vaporization cavity.

Abstract: An adaptive transmission scheme of the channel environment in the multi-antenna wireless transmission system can raise the spectrum use rate and power efficiency of the communication system. Compared with traditional single antenna input and single antenna output, the channel environment in MIMO wireless communication system is more complex. When the terminal is moving, the different types of channels between terminal and base station can be gone through and then its capacity can be changed more largely. Embodiments of the disclosure are directed to systems that transmit high speed data by way of a plurality of transmitting and/or receiving antennae, and particularly to a transmission scheme in different channel environments in a multi-antenna wireless transmission system.
