Abstract: An electronic device may include a body and a functional assembly. The body may define a receiving cavity. The functional assembly may be rotatably connected to the body, and be configured to rotate in a first direction and a second direction to protrude out of the receiving cavity. The functional assembly provided by the present disclosure may not occupy any space of a front face of the electronic device.

Abstract: A method for extracting f wave from a single-lead electrocardiography signal is provided. The method includes: establishing a two-channel temporal convolutional neural network model, including two coding submodules, two mask estimation submodules, an information fusion module and two decoding submodules; constructing a training data set of ECG signals; training the two-channel temporal convolutional neural network model, and saving the trained model. The two-channel temporal convolution neural network encodes and decodes a QRST complex and the f wave respectively, and uses a mask of information fusion to estimate and construct regular items to restrict a distribution difference of QRST component coding features, so as to reduce the distortion of the QRST complex, select potential features of a QRST complex and f wave with high signal-to-noise ratio, and thus improve a detection accuracy of the f wave.

Abstract: An electronic device includes a body, a functional assembly, and a sliding mechanism. The body may define a receiving cavity. The functional assembly may be rotatably connected to the body. The sliding mechanism may be received inside the body. The sliding mechanism may include a sliding rail arranged on one of the body and the functional assembly, and a sliding element arranged on the other of the body and the functional assembly. The sliding element may be slidable along the sliding rail, such that the functional assembly is able to rotate from an inside of the receiving cavity to an outside of the receiving cavity or rotate from the outside of the receiving cavity to the inside of the receiving cavity.
