Abstract: A method and an apparatus for transmitting frame data between a near-end device and a remote device are provided. The method includes: generating, by the near-end device, a base frame in a user-defined frame format, wherein a PHY converting chip is built in the near-end device, the base frame includes a first number of super groups, each super group includes a second number of base groups, and each base group includes media access control (MAC) frame structure data and an interframe gap; matching duration of the MAC frame structure data and the interframe gap with an output timing sequence of the PHY converting chip; and converting the base frame into an optical fiber signal through the PHY converting chip, and sending the optical fiber signal to the remote device.

Abstract: The invention relates to a method of raindrop detection on a vehicle windscreen by capturing images using a camera which is at least focused on the windscreen, including a step of detecting edges (102) in a research area of said captured images, characterized in that said method of raindrop detection comprises a rejection step (103) in which edges that are uncharacteristic with respect to a raindrop are rejected. This invention also relates to an associated driving assistance device.

Abstract: The invention relates to a method of fog and raindrop detection on a windscreen (200), comprising a raindrop detection application (201) and a fog detection application (202), characterized in that said fog detection application (202) comprises a step (202b) in which an indication of the presence of raindrop is detected, said indication of raindrop presence triggering a switch from said fog detection application (202) to said raindrop detection application (201).
