Abstract: A wearable device includes a conductive frame and a parasitic stub. A first ground point and a feed point are disposed on the frame. The parasitic stub has a first slot and a second slot. The parasitic stub and the frame each have a ring shape, and are spaced along a ring circumference. The parasitic stub is divided into a first parasitic part and a second parasitic part with approximately equal lengths by the first slot and the second slot.

Abstract: This disclosure provides a service data processing method. The method includes: receiving service data; obtaining a processing manner for processing the service data; performing first timeslot-based multiplexing, bit width conversion, and second timeslot-based multiplexing on the service data when a bandwidth of the service data is less than a first threshold, to obtain an intermediate frame; performing single-level timeslot-based multiplexing on the service data when the bandwidth of the service data is not less than the first threshold, to obtain the intermediate frame; mapping the intermediate frame to an optical transport network (OTN) frame; and sending the OTN frame. A first bit width and a first bandwidth based on which the first timeslot-based multiplexing is performed are different from a second bit width and a second bandwidth based on which the second timeslot-based multiplexing and the single-level timeslot-based multiplexing are performed.

Abstract: An optical signal transmission method and an apparatus are provided, to reduce processing complexity while maximizing bandwidth utilization. An OPUk multiplexing frame with a bit rate greater than 1.25 Gbps is constructed by using a structure of an OPU0 multiplexing frame, so that the structure of the OPU0 multiplexing frame can be reused by a structure of the OPUk multiplexing frame, and the structure of the OPUk multiplexing frame is aligned with the structure of the OPU0 multiplexing frame. The OPUk multiplexing frame includes an integer multiple of OPUk frames, and a boundary of the OPUk multiplexing frame remains aligned with a boundary of the OPUk frame. According to this application, when mapping an OSU frame, an OTN device may map the OSU frame to the OPUk multiplexing frame based on the reused structure of the OPU0 multiplexing frame.

Abstract: An image management method includes: after a video stream sent by a camera is obtained, recognizing a face image in the video stream through face recognition; comparing the image with a face image that is in an area in which the camera is located in a database; and if the comparison fails, expanding the area in which the camera is located around, and then comparing the face image with face images in an area obtained after the area in which the camera is located is expanded.

Abstract: A service mapping processing method for an optical transport network, an apparatus, and a system are provided, where the method includes: generating mapping adaptation indication information according to a mapping granularity of a to-be-carried LO ODU, where the mapping granularity is M×g bytes, M is a quantity of timeslots occupied by the to-be-carried LO ODU in an OPUCn, g is a size of a mapping granularity corresponding to each timeslot of the timeslots occupied by the LO ODU, and g is a positive integer greater than 1; mapping, according to the mapping adaptation indication information, the to-be-carried LO ODU to an ODTUCn.M payload area; encapsulating the mapping adaptation indication information into the ODTUCn.M overhead area; encapsulating the ODTUCn.M into an OTUCn; and sending the OTUCn to a receive end device. The method avoids that OTUCns that use different mapping granularities cannot interwork between a receive end and a transmit end.
