The utility model discloses an anti-interference layered composite audio cable, which relates to the technical field of audio cables and comprises a total PVC (polyvinyl chloride) outer sheath, a total tinned copper woven mesh shielding layer is arranged on the inner side of the total PVC outer sheath, a total aluminum foil shielding layer is arranged on the inner side of the total tinned copper woven mesh shielding layer, and a total aluminum foil shielding layer is arranged on the inner side of the total aluminum foil shielding layer. The inner side of the total aluminum foil shielding layer is provided with a total PVC inner sheath, and the interior of the total PVC inner sheath is filled with an anti-interference filler. According to the utility model, a digital optical fiber signal, a coaxial signal and an analog audio power signal are simultaneously transmitted through a single wire, the complexity of wiring and the required space are reduced, and meanwhile, mainstream audio equipment interfaces are adapted, cables in the mainstream audio equipment interfaces can be connected according to use requirements, and the dependence on adapters is reduced. When a multi-interface device is connected, the remaining two cables can also be used as standby, when the cable in use is damaged, rewiring is not needed, other cables can be used, and a multi-layer anti-interference structure is provided, so that the anti-interference capability is strong.

This invention discloses an intelligent shoulder joint range of motion measurement system and method based on multi-sensor fusion, comprising a hardware measurement unit and a smart terminal communicatively connected thereto. The hardware measurement unit includes: a trunk sensor module for fixing to the user's trunk to acquire trunk posture data; an upper arm sensor module for fixing to the upper arm on the same side as the shoulder being measured to acquire upper arm posture data; and a data processing and communication module electrically connected to the trunk sensor module and the upper arm sensor module, respectively, for receiving and processing the trunk posture data and the upper arm posture data, calculating the spatial relative posture angle of the upper arm relative to the trunk, and wirelessly transmitting the spatial relative posture angle to the smart terminal. This invention addresses the long-standing pain points of traditional goniometers in clinical practice, such as strong subjectivity, cumbersome operation, and inability to record dynamic processes.
