Abstract: A wood-made straw includes a hollow tube formed by a wood sheet wound and an adhesive film wrapping the outer surface and the inner surface of the hollow tube. The adhesive film includes an edible glue made of natural material. The edible glue can improve the hardness of the hollow tube and have flexible, soft, and moistureproof properties. The wood sheet further includes two log sheets and a paper sheet therebetween to improve the whole strength and waterproof properties. The wood-made straw is made of natural material which is rapidly biodegradable. It costs 1-6 months to naturally decompose the wood-made straw. Thus, the wood-made straw has a vale for environment protection.

Abstract: The present method first provides an image capturing device so that the image obtained by the image capturing device contains only dark-colored road paving and a light-colored lane marker appearing in the left or right portion of the image. The present method then determines the distribution of the light-colored pixels in each consecutive image captured. When the distribution of the light-colored pixels is shifted towards the other side of the images, the motor vehicle is assumed to be deviating from its current traveling lane. When the distribution of the light-colored pixels conforms to a terminal condition, the present method provides at least an audible alarm such as a siren or a pre-recorded voice message to alert the driver.
