Abstract: A coating die head includes a first die block, a second die block, a third die block, and a fourth die block that are sequentially arranged at intervals. The first die block and the second die block form a first slot therebetween, the second die block and the third die block form a second slot therebetween, and the third die block and the fourth die block form a third slot therebetween. Each of the first die block, the second die block, the third die block, and the fourth die block has a die lip at a surface thereof. A length of the die lip of the second die block ranges from 100 micrometers to 200 micrometers. A ratio of a length of the die lip of the third die block to the length of the die lip of the second die block ranges from 1.5 to 7.

Abstract: A driving assistance system and a driving assistance method are provided. The driving assistance system includes a plurality of image capturing devices, a congestion calculation module, and a determination module. The image capturing devices capture a plurality of regional images of a plurality of road sections of the target lane. The congestion calculation module calculates a plurality of congestion levels corresponding to the road sections according to the regional images. The determination module provides a lane changing message to the vehicle according to the congestion levels.

Abstract: A lithium battery is provided. The lithium battery comprises an positive electrode plate having a first surface, a negative electrode plate having a second surface, a first thermal insulating layer and a separator. The first surface is opposite to the second surface. The thermal insulating layer is disposed on one of the first surface and the second surface. The thermal insulating layer is comprised of an inorganic material, a thermal activation material and a binder. The separator is disposed between the positive electrode plate and the negative electrode plate.

Abstract: To form a brightness enhancement film of cholesteric liquid crystal, a photopolymerizable liquid crystal is first formed on a first substrate. A second substrate then is formed on the liquid crystal substance to form a sandwich structure. The sandwich structure is subsequently submitted to a lamination process that generates shear stress thereon. Finally, an energetic irradiation including UV irradiation is performed to solidify the layer of liquid crystal into a liquid crystal polymer film. The second substrate then is selectively removed. The above steps are repeated until a desired reflected wavelength range of the liquid crystal film is obtained.
