Abstract: A vibrating lens comprises a control assembly configured to control a light-transmissive assembly to deflect and the light-transmissive assembly located at a side of the control assembly. The control assembly includes a substrate having a first opening and a first edge region surrounding the first opening and a control coil printed on the first edge region. The light-transmissive assembly includes a bearing plate having a second opening and a second edge region surrounding the second opening, a lens covering the second opening and a magnetic assembly located on the second edge region. The lens and the magnetic assembly are disposed at a side of the bearing plate proximate to the control assembly. Orthogonal projection of the first opening on a plane parallel to a surface of the substrate away from the lens coincides with orthogonal projections of the lens on the plane and the second opening on the plane.

Abstract: A projection apparatus includes a light source assembly, a display control circuit, a light valve, a vibrating lens drive assembly, and a vibrating lens. The display control circuit is configured to obtain a plurality of sub-images; in a process of emitting beams of three primary colors by the light source assembly to the light valve sequentially, control, according to primary color parameters of the pixels in each sub-image, the light valve to sequentially reflect beams corresponding to the plurality of sub-images to the vibrating lens; and in a process of projecting each sub-image, transmit a vibrating lens current control signal corresponding to the sub-image to the vibrating lens drive assembly. The vibrating lens drive assembly is configured to provide at least one vibrating lens driving current to the vibrating lens according to the vibrating lens current control signal corresponding to the sub-image.

Abstract: A modular energy-dissipating fabricated structure for a transmission tower includes a base, two T-shaped beams, a vibration damping mechanism, a connection plate, and four supporting beams. The vibration damping mechanism slides to generate the damping force and energy dissipation. The larger the displacement of the vibration damping mechanism, the greater the damping force provided by the system. This effectively reduces vibration of an upper structure of the transmission tower, and lowers a probability of damaging the upper structure in a natural disaster. The modular energy-dissipating fabricated structure realizes hierarchical control under different loads. Under an action of a dynamic load such as a strong wind, a small sliding range of the vibration damping mechanism can realize vibration damping and energy dissipation purposes of the structure. When a strong dynamic load such as an earthquake is applied to the structure, the vibration damping mechanism reduces an impact on the structure.
