Abstract: This application discloses a vehicle security communication method and apparatus, a vehicle multimedia system, and a vehicle. The vehicle includes an open system, a security chip and a closed system, the open system is connected to the closed system through the security chip, the method is applied to the security chip, and the method includes: receiving a first vehicle data instruction from the closed system, where the first vehicle data instruction includes original vehicle data; encrypting the original vehicle data to obtain corresponding encrypted vehicle data; and replacing the original vehicle data in the first vehicle data instruction with the encrypted vehicle data to form a second vehicle data instruction, and sending the second vehicle data instruction to the open system.

Abstract: The present invention relates to the field of remote access technologies, and discloses a remote conference implementation method and apparatus, where the method is specifically that: a conference terminal detects a first mobile terminal at a current conference site, sends, a first dialing instruction to the detected first mobile terminal, to enable the first mobile terminal to establish an audio link according to an identifier of a second mobile terminal; and encodes a received audio signal of another conference site and/or an obtained audio signal of the current conference site, sends the encoded audio signal to the second mobile terminal based on the audio link, receives an audio signal sent by the second mobile terminal by using the first mobile terminal, decodes the audio signal, and then plays the decoded audio signal. In this way, a sound pickup range can be effectively expanded.

Abstract: A wire holder for managing and aligning wires to corresponding traces in a PCB. The wire holder assists in the manufacturing process of cables and connectors, and especially during the welding process by minimizing the amount of time spent by users manually adjusting the wire positions. The wire holder includes a shaft having a plurality of teeth and claws forming a plurality of comb openings that may either be open so wires can be inserted sideways or closed so wires must be inserted into the comb openings. The plurality of wires are collected into the wire holder and the wire holder is subsequently aligned with the corresponding traces on the PCB prior to the welding of the wires. The wire holder may align wires for double sided PCBs.
