Abstract: The present application discloses a communication device, where the communication device includes an antenna and a communication apparatus. The antenna includes a feed and a wiring board, the feed including a dipole unit. The dipole unit includes a first dipole and a second dipole, the second dipole being formed on one side of the wiring board. The communication apparatus includes a circuit board. The first dipole is formed on a surface of the circuit board. The circuit board is provided with a first slot. The wiring board extends through at least a portion of the first slot and connected to the circuit board. Both the first dipole and the second dipole are electrically connected to the circuit board.

Abstract: An approach to generating electrical energy includes providing a composite material having liquid metal droplets dispersed in at least one of an ionically-conductive liquid or an ionically conductive polymer. The composite material is enclosed within a flexible, stretchable enclosure. At least two electrodes are embedded within the composite material. The enclosure is mechanically deformed to cause relative movement between at least one of the electrodes and the composite material, thereby rupturing oxide layers present on surfaces of the liquid metal droplets and inducing an electrochemical reaction that generates electrical energy.

Abstract: A light adjustment device includes a lens head and a lens tube disposed around the lens head and slidable relative to the lens head in a first direction. A rotating assembly is rotatably mounted on one of the lens tube and the lens head. The rotating assembly is drivingly connected with the other of the lens tube and the lens head through a transmission structure, at least a portion of the transmission structure is rotatable with the rotation of the rotating assembly, the transmission structure is configured to convert a rotational output of the rotating assembly into a linear output of the other of the lens tube and the lens head, so that the lens tube is capable of reciprocating linearly in the first direction relative to the lens head under the action of the linear output.

Abstract: The present application provides a photography light assembly, comprising a light body and a power delivery module, wherein the power delivery module is provided with a first connecting component and a first connector, the light body is provided with a second connecting component and a second connector, the first connecting component and the second connecting component are detachably engaged, and the first connector is electrically connected to the second connector when the first connecting component is installed to the second connecting component. By incorporating detachable connection structures and connectors between the light body and the power delivery module, it allows the power delivery module to be installed to the light body while establishing an electrical connection. This enhances the integration of the light body and the power delivery module, achieving power supply for the light body, resulting in ease of operation, convenient storage, portability, and aesthetic appeal.
