The application discloses a kind of Chinese fifth percentile old male passenger injury bionical model with sign, also called biomechanical model, is the digital computing tool in the technical field of intelligent high-end detection equipment of automobile safety.This application is based on the fifth percentile male automobile passenger injury bionical model of thurstone, its each part is adjusted with age-related change to represent old male.The injury bionical model provided by the application meets the Chinese fifth percentile old male sign parameter;The model has detailed human anatomy structure characteristics.The Chinese fifth percentile old male passenger injury bionical model developed and constructed in the application not only provides a high-fidelity simulation tool for studying the injury mechanism of Chinese old passengers during the collision process, but also helps to deepen the understanding of the complex relationship between age change, body geometry and tissue mechanical properties and injury risk.

The invention relates to the production method of anthropomorphic head-neck phantom in heterogeneous structure and in a form suitable for human anatomy using 3D printer and molding technique.

This invention discloses a rare-earth magnetic graphene far-infrared spinal health pillow. Based on human anatomy and biomechanics, the pillow body is designed with seven independent functional zones. In the supine position, the neck support zone consists of, from top to bottom, a biomimetic curved support layer, a negative ion health function layer, a far-infrared emission source layer, a support filling layer, and a magnetic therapy composite array layer. Height-adjustable airbags are also provided within the zone. This invention uses graphene far-infrared light waves to physically excite the negative ion substrate to release negative ions, abandoning high-voltage ionization methods, resulting in no leakage, no radiation, and no harmful byproducts. The far-infrared rays are amplified through secondary excitation, achieving focused energy and deep therapy. The support layer features a soft upper layer and a hard lower layer, while the magnetic therapy layer uses rare-earth permanent magnets and soft magnetic topological arrangements to form a stable and uniform magnetic field. The product is suitable for various sleeping positions and body types, with a negative ion concentration of 1500-3000 ions / cm³ and a far-infrared emissivity of no less than 85%. It combines cervical spine alignment, calming and sleep aid, and microcirculation regulation functions. It is structurally stable, safe, durable, and offers outstanding health benefits.

The invention relates to an improved guide splint (1) for dental procedures in fully or partially edentulous patients, having a lower face (1a) with an anatomical shape designed to rest on a jaw of the patient and comprising at least one through hole (2) configured to serve as a reference for a dental procedure. The splint (1) of the invention also comprises at least one recess (3) on the lower face of same configured for snap-fit engagement with at least one lug (T) protruding from the gum.

The present application proposes a chest and abdominal respiration signal decoupling and reconstruction method based on millimeter wave radar. Using a millimeter wave multiple-input multiple-output radar device, the radar echo is first mapped to a three-dimensional space using 3D beamforming technology, mapping the one-dimensional time domain signal to a spatial energy heat map containing distance, azimuth, and elevation three-dimensional information. Then, through spatial filtering strategy, the physiological vibration source signal clusters of the subjects with coupling relationship are separated. When the physiological vibration source includes the chest reflection area of the first anatomical site and the abdominal reflection area of the second anatomical site, combined with the adaptive best point selection algorithm, according to the anatomical features of the human body, the chest reflection area and the abdominal reflection area are physically located and distinguished in the three-dimensional space, and the independent breathing waveform is extracted from the body surface reflection to perform high-precision spatial separation and anti-interference waveform extraction operation of chest and abdominal respiration movement. The present application can realize high-precision spatial separation and anti-interference waveform extraction of chest and abdominal respiration movement.

The application discloses a bionic model of a bicycle rider injury, also referred to as a biomechanical model, with the Chinese 50th percentile male body sign, which is a digital calculation tool in the technical field of vehicle safety and intelligent high-end detection equipment. The bionic model of the injury conforms to the Chinese 50th percentile male body sign parameter of the latest human body size statistical data of the China Standardization Research Institute; the model has detailed human anatomy structure features and conforms to the standard riding posture in the international standard ISO 19206-4:2020. The content of the application can provide a theoretical basis for optimizing a bicycle rider safety protection system and has a wide application prospect in improving the safety protection level of vulnerable road users in China.
