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 discloses a heavy metal cadmium low-accumulation wheat variety screening disc and a use method, and relates to the technical field of wheat screening. The device comprises a screening box, a screening barrel is rotationally installed in the screening box, filtering holes are formed in the screening barrel, a first gear is fixedly installed on the screening barrel, the first gear is meshed with a second gear, an output shaft of a driving motor is fixedly installed on the second gear, and a first transmission mechanism is arranged on the output shaft of the driving motor; the first transmission mechanism is used for driving the conveying shaft to rotate, and an output shaft of the driving motor is provided with a second transmission mechanism. According to the wheat seed screening device, the driving motor drives the screening barrel to rotate, meanwhile, wheat seeds are evenly scattered through the first transmission mechanism, the wheat seeds and the screening barrel rotate in the opposite direction, bran, dust and other impurities on the surfaces of the wheat seeds are effectively removed, and furthermore, a cam is driven by the second transmission mechanism to rotate, so that a first filter screen plate and a second filter screen plate vibrate; graded screening of the wheat seeds is achieved.

This invention discloses a cable tensioning device, method, and application for large-angle vertical rotation of long linear structures, belonging to the technical field of installation devices for large-angle vertical rotation of long linear structures. Located at the cable anchorage end of the higher part of the vertical rotation component, it includes a cable force identification module, a mechanical transmission module, and a tensioning module. The cable force identification module includes several force measuring elements, each disposed on each strand of the cable. The mechanical transmission module includes a three-stage rotating hinge structure, comprising a first rotating hinge structure, a second rotating hinge structure, and a third rotating hinge structure connected sequentially. This technical solution addresses the problem in existing technologies where, during large-angle vertical rotation of long linear structures, individual strands in the cable may become slack, and the limitation of the installation component's length and installation height makes it difficult to tension the slack strands.
