Abstract: A wearable device (100) includes a body (1) and a detection electrode (21). The body (1) includes an electrocardiosignal collection circuit (11), and an inner electrode (12) and an outer electrode (13) that are electrically connected to the electrocardiosignal collection circuit (11). The inner electrode (12) is configured to collect an electric potential signal of a first wearing position (200), and the outer electrode (13) is configured to collect an electric potential signal of a non-wearing position (300). The detection electrode (21) can move relative to the body (1), and the detection electrode (21) is configured to electrically connect to the electrocardiosignal collection circuit (11) and collect an electric potential signal of a second wearing position (400). The non-wearing position (300) and the second wearing position (400) are different from the first wearing position (200). The wearable device (100) can measure electrocardiosignal data in time.

Abstract: Embodiments of the present invention disclose a method and an apparatus for detecting inter-instruction data dependency. The method comprises: comparing a thread number corresponding to a historical access operation with a thread number corresponding to a write access operation, if the thread number corresponding to the write access operation is less than the thread number corresponding to the historical access operation, which indicates existence of data dependency for a to-be-detected instruction, terminating the detection; or comparing a thread number corresponding to a historical write access operation with a thread number corresponding to a read access operation, if the thread number corresponding to the read access operation is less than the thread number corresponding to the historical write access operation, which indicates existence of data dependency for the to-be-detected instruction, terminating the detection.

Abstract: A packet backpressure detection method and apparatus are provided. The method includes: a device which having a Peripheral Component Interconnect Express (PCIe) port storing a plurality of packets for transmission in a packet queue and storing a packet that is to be transmitted next in a first buffer, where the queue comprises a plurality of packets that are to be transmitted via the PCIe port; and the queue is stored in a second buffer; recording a storage duration of each packet stored in the first buffer, and accumulating the storage duration of each packet stored in the first buffer; removing the packet from the first buffer after the packet is transmitted via the PCIe port; and generating an indication of packet pressure at the PCIe port based on the accumulated storage duration.

Abstract: A carbon fiber watch case includes a main body structure and a conductive structure. The main body structure has an inner surface and an outer surface. The conductive structure has a first contact on the inner surface and a second contact on the outer surface to electrically connect the inner surface and the outer surface of the carbon fiber watch case. The main body structure includes a braided body and a polymer body. The braided body includes a carbon fiber, and the braided body has a network-like structure. The polymer body at least fills a gap of the network-like structure of the braided body so that the braided body and the conductive structure form an integrated structure.

Abstract: This application relates to a spring bar assembly, a watch strap, and a watch. The spring bar assembly includes a mounting base, a spring bar, a button, and a lever. Both the spring bar and the button are mounted on the mounting base. The button is capable of moving relative to the mounting base, and a movement direction of the button is perpendicular to an axial direction of the spring bar. One end of the lever extends into a guide groove of the button and abuts against first side walls of the guide groove, and the other end of the lever is connected to the spring bar. The button is capable of driving the spring bar to move relative to the mounting base in the axial direction of the spring bar by using the lever.
