  • Publication number: 20240145911
    Abstract: An antenna correcting system is provided. The antenna correction system compares amplitudes of antenna signals that are emitted or received respectively by a plurality of antenna units with each other to select one of the amplitudes as target amplitude. The antenna correction system corrects the amplitude of each of the antenna signals according to the target amplitude. As a result, the amplitudes of the antenna signals are the same as each other or approximate to each other. After the amplitudes of the antenna signals are corrected, the antenna correction system compares phases of the antenna signals with each other to select one of the phases as a target phase. The antenna correction system corrects the phase of each of the antenna signals according to the target phase. As a result, the phases of the antenna signals are the same as each other or approximate to each other.

  • Patent number: 11769526
    Abstract: Magnetic recording media with a thermal spin injection layer that induces a spin injection in a magnetic recording layer in response to a thermal gradient in the thermal spin injection layer. The thermal spin injection layer may comprise an antiferromagnetic, a ferromagnetic, or a ferrimagnetic material that demonstrates a Spin Seebeck effect. In turn, when heating the magnetic recording media (e.g., with a near field transducer of a HAMR drive), the thermal gradient may be established in the thermal spin injection layer. A resulting spin torque field may assist in switching a magnetic domain in the magnetic recording layer by providing an assistive field to at least initiate switching of the magnetic domain. In turn, more reliable or efficient operation of a storage drive comprising the magnetic recording media may be realized.

  • Publication number: 20230288080
    Abstract: A filter structure includes a base and a filter. The base is provided with an aperture and multiple second slopes around the aperture. The filter is connected to the base and slidable relative to the base. The filter has a first sliding block and multiple second sliding blocks. The first sliding block passes through the aperture. Each second sliding block abuts against each second slope and is slidable along each second slope. Therefore, the gap between the main body and the filter may be reduced to increase the filtering efficiency of the air purifier and the filter structure.

  • Patent number: 11553824
    Abstract: An automatic guiding method for a self-propelled apparatus (10) is provided. The self-propelled apparatus (10) turns and irradiates when a signal light emitted by a charging dock (20) is sensed by a flank sensor (103), and changes its turn direction when another different signal light from the charging dock (20) is sensed by a forward sensor (102). The charging dock (20) switches to emit another signal light different from the signal light currently emitted when each time is triggered by the signal light emitted by the self-propelled apparatus (10). Repeatedly execute the above actions and make the self-propelled apparatus approach the light-emitting unit (202) until the self-propelled apparatus (10) reaches a charging position. It can accurately guide the self-propelled apparatus (10) to the charging position by arranging only two sensors on the self-propelled apparatus.
