A displacement sensing device includes a wave transmitter that transmits a modulated wave having a plurality of frequencies to an object, a wave receiver that receives a reflected wave from the object and generates a reception signal indicating a reception result, and a control section that controls transmission of the modulated wave by the wave transmitter and acquires the reception signal from the wave receiver. The control section outputs a first transmission signal to the wave transmitter to cause transmission of the modulated wave in a first measurement period, acquires a first reception signal in response thereto, extracts first phase information indicating a phase specified in correlation between the first transmission signal and the reception signal, outputs a second transmission signal to the wave transmitter in a second measurement period following the first measurement period, acquires a second reception signal in response thereto, extracts second phase information indicating a phase in correlation between the second transmission signal and the reception signal, and senses displacement of the object in the first measurement period and the second measurement period based on a difference between the first phase information and the second phase information.

This invention belongs to the field of heavy metal removal technology, specifically disclosing an extract from the leaves of a Solanaceae plant, its extraction method, and its application. The extraction method includes the following steps: S1, mixing tomato and pepper leaves, chopping them to obtain a preliminary mixture; S2, mixing a compound microbial agent with the preliminary mixture obtained in S1, fermenting, sterilizing, centrifuging, filtering through a 0.45μm filter membrane, discarding the precipitate, and obtaining a fermented preliminary mixture; S3, concentrating the fermented preliminary mixture obtained in S2 under reduced pressure to obtain a concentrated fermentation broth; S4, adding sodium carboxymethyl cellulose to the concentrated fermentation broth obtained in S3, stirring evenly, and freeze-drying to obtain the Solanaceae plant leaf extract. This Solanaceae plant leaf extract can effectively remove cadmium from aquatic products, aiding in the growth recovery of aquatic products after cadmium stress, and can also effectively maintain the pH value of white clam muscle, reducing lactic acid accumulation and glycogen consumption, and maintaining the freshness of the meat.

This invention provides a dynamic mechanical structure wind vane ground-mounted landscape tower, relating to the field of communication landscape towers. It includes a landscape column, a flipping guide rod, a marker head, a marker tail, and an extension plate. The landscape column has two annular sub-tower structures on its upper and lower sides of its outer end face, symmetrically positioned. The landscape column's outer end face has four outward-facing adjustment cavities. This design uses a threaded connection to move a telescopic connecting cylinder outward, which in turn moves the connecting guide plate, and then, through transmission, moves the directional marker outward. As the directional marker moves outward, it makes it easier for pedestrians to understand the wind direction, providing a direct visual representation of the wind's direction. This design also deforms the extension plate, increasing the wind-receiving area of ​​the marker tail, thereby expanding the wind-sensing area and improving the wind vane's sensing accuracy. This facilitates adjustment and sensing of the wind direction angle, and the change in the dynamic mechanical structure enhances the wind vane's sensing effect.
