This invention provides a wireless, passive force-position implantable growth monitoring system and its fabrication method for early-onset scoliosis correction. The system includes: a connected compressible capacitive sensor and a flexible wireless antenna coil; the compressible capacitive sensor is connected to a self-growing early-onset scoliosis correction implant growth rod, and the flexible wireless antenna coil is disposed within the body. The compressible capacitive sensor and the flexible wireless antenna coil together constitute an LCR resonant circuit; the compressible capacitive sensor monitors the pressure changes caused by the elongation of the self-growing early-onset scoliosis correction implant growth rod during tissue or bone growth, thereby causing changes in capacitance and resulting in changes in the resonant frequency of the LCR resonant circuit; the resonant frequency change is detected and read out wirelessly via an external readout device. This system is designed to meet the needs of digital rehabilitation, requires no internal power supply, and has a stable structure, making it suitable for growth monitoring after early-onset scoliosis correction surgery.

The invention relates to a near-zero warping thermal adaptation structure and an intelligent optimization method thereof, the structure comprises a fixed connection substructure and N thermal deformation release substructures, the fixed connection substructure comprises two solid structures connected through bolts, one solid structure is located in a functional component, and the other solid structure is located in a bearing component. The N thermal deformation release substructures are arranged between the functional component and the bearing component and are distributed in an axial symmetry mode relative to the center line of a connecting bolt for fixing the connecting substructures. The structure is described and constructed by adopting a movable deformable component method, and geometric parameters of an iterative thermal deformation release substructure are updated through a genetic algorithm to obtain an optimal structural design oriented to a space non-uniform and time-varying temperature field. And the integrated design requirements of thermal dimensional stability during the on-orbit period of the spacecraft structure and high rigidity and strength during the launching period can be met.

This reconstruction structure, based on a transmissive phase discontinuity surface, generates a circularly polarized beam, belonging to the field of beam reconstruction. Traditional optical rotation response and beam direction control techniques typically rely on bulky and complex devices to achieve these functions, which not only limits system integration but also reduces signal processing efficiency. The proposed structure comprises an array of n×n integrated layers, of which n types exist. The first, second, and third metal structural layers have elliptical annular cross-sectional shapes. The rotation angles of the first, second, and third metal structural layers on each type of integrated layer are not identical; these angles are the angles between the major axis of the elliptical annulus and the negative direction. The left-hand or right-hand circularly polarized wave phases of the n integrated layers differ by m° sequentially, and the arrangement range of the left-hand or right-hand circularly polarized wave phases of the n integrated layers is from 0 to 2π. This structure is used to generate a circularly polarized beam.

The utility model discloses a horn-type table frame and a table based on the same. The horn-type table frame comprises a top frame, a bottom frame and a horn-type supporting main body, wherein the top frame and the bottom frame are horizontally arranged, and the horn-type supporting main body is arranged between the top frame and the bottom frame and is defined by a plurality of bamboo battens which are sequentially and tightly leaned to form a large upper opening and a small lower opening; the top end of each bamboo strip piece is fixedly connected to the inner circumferential edge of the top frame, and the bottom end of each bamboo strip piece is fixedly connected to the inner circumferential edge of the bottom frame. The top frame is provided with a table top installation groove, and the table top plate can be embedded in the table top installation groove. The trumpet type table frame is free of edges and corners, not prone to collision and simple in design style, the whole table looks more designed and is high in design sense, only the trumpet type supporting body serves as a central supporting component, occupied space is small, and the table is easy to place. And the horn-type supporting main body is defined by the multiple bamboo battens in sequence in an abutting mode, the structure is firm, the structural stability is good, and the service life of the table is long. Due to the design that the projection lamp is arranged in the horn type supporting body, a good business negotiation atmosphere can be created.
