Abstract: This disclosure provides an in-vehicle mid-air gesture-based interaction method, an electronic apparatus, and a system, and relates to the field of intelligent vehicle technologies. The method includes: obtaining a first mid-air gesture detected by a camera; and starting, when a preset response operation corresponding to the first mid-air gesture matches a first user who initiates the first mid-air gesture, the preset response operation corresponding to the first mid-air gesture in response to the first mid-air gesture. The method can be used in an in-vehicle mid-air gesture-based interaction scenario, reduce a mid-air gesture operation rate, and improve driving safety and interaction experience.

Abstract: A clock port attribute recovery method includes a network device setting a value of a port attribute of a clock port of the network device to a first value based on the clock port not receiving any one of three types of clock messages: N synchronization messages, follow-up messages, and delay response messages within a timeout interval, where the first value indicates that a message is lost on the clock port. Based on a case that a recovery condition is met, the network device sets the value of the port attribute of the clock port to a second value, where the second value indicates that a status of the clock port is that the message is not lost.

Abstract: A clock oscillator, a clock oscillator production method and use method, and a chip including the clock oscillator are provided. The clock oscillator includes a resonator, a shock-absorbing material layer, and a base, and at least a part of the shock-absorbing material layer is located between the resonator and the base. In the clock oscillator, the shock-absorbing material layer is added between the resonator and the base, and the shock-absorbing material layer can effectively prevent a mechanical wave from being conducted between the base and the resonator, so that the resonator is protected from external vibration. This can ensure, when there is external vibration, that an output frequency of the resonator is not deteriorated and improve shock absorption performance of the clock oscillator.

Abstract: A clock determining method includes: when both a second network device and a first network device are synchronous with a reference clock, simulating, by using delay information between the second network device and the first network device and clock frequency information of the second network device, a second virtual clock synchronized with a first virtual clock, where the first virtual clock is used to simulate a clock of the first network device. A clock of the second network device can thus be simulated to perform a subsequent operation by using the simulated clock. For example, the simulated clock may be used to estimate precision time protocol (PTP) message synchronization performance of the second network device. Therefore, the PTP message synchronization performance of the second network device may be pre-determined before a global navigation satellite system (GNSS) fails, to guide network operation and maintenance activities.

Abstract: This application provides example methods for establishing a service path in a transport network and example systems. One example method includes, obtaining, by an automatically switched optical network (ASON) first node, a service path computation result path. The service path includes the ASON first node, an ASON last node, and at least one first edge network node. The method also includes sending, by the ASON first node, a path establishment request message to a downstream node. The path establishment request message carries cross-connection configuration information of the ASON last node and the at least one first edge network node. The method further includes receiving, by the ASON first node, a path establishment response message of the downstream node. The path establishment response message indicates that cross-connection configuration for the ASON last node and the at least one first edge network node is complete.

Abstract: A method for synchronizing clocks, including: receiving at least two clock signals, where the at least two clock signals are sent by a bidirectional clock tracking link respectively corresponding thereto; setting two or more clock signals coming from a same network element into a same clock source group; selecting one clock signal in a same clock source group as a currently tracked clock signal; and if the currently tracked clock signal belongs to the clock source group, respectively sending a standby clock signal carrying quality-level do not use information by using the bidirectional clock tracking link respectively corresponding to each of the clock signals in the clock source group. The present invention achieves the effect that in the scenario where there are two or more bidirectional clock tracking links between two network elements, a clock tracking loop will not be generated.
