A shielding device for forward facing and / or windshield mounted / located sensors on an automobile protects sensors in close proximity to the windshield from temperature extremes associated with sunlight and extreme cold or wind.

The windshield is subject to a substantial solar load, often emphasized by the angle of the windshield in direct sunlight. A reflective, insulating substrate disposed over the windshield mitigates extreme heat that can damage sensors in thermal communication with the windshield surface. The substate is affixed via the door seam, magnetic attachment, or engagement with the side mirrors or wipers.

This invention relates to a wind power prediction method for extreme cold wave weather. First, multi-dimensional time-series data is preprocessed to form a unified input sequence. Using a multi-index joint criterion and a time window, the unified input sequence is processed to obtain normal samples and samples labeled with a cold wave. The samples labeled with a cold wave undergo a two-layer sample augmentation to obtain augmented cold wave samples. Then, the samples labeled with a cold wave, the augmented cold wave samples, and the normal samples are merged into an augmented training set. The augmented training set is input into a trend prediction module to obtain a trained trend prediction module. Real-time multi-dimensional time-series data is acquired and input into the trained trend prediction module, which outputs an inverse-standardized power prediction, thus completing the wind power prediction for cold wave weather. Through the above design, this invention effectively mitigates the impact of extreme weather on prediction, achieving high-precision and stable prediction while maintaining a lightweight and real-time model.
