Abstract: Method for source localization for cable cut prevention using distributed fiber optic sensing (DFOS)/distributed acoustic sensing (DAS) is described that is robust/immune to underground propagation speed uncertainty. The method estimates the location of a vibration source while considering any uncertainty of vibration propagation speed and formulates the localization as an optimization problem, and both location of the sources and the propagation speed are treated as unknown. This advantageously enables our method to adapt to variances of the velocity and produce a better generalized performance with respect to environmental changes experienced in the field. Our method operates using a DFOS system and AI techniques as an integrated solution for vibration source localization along an entire optical sensor fiber cable route and process real-time DFOS data and extract features that are related to a location of a source of vibrations that may threaten optical fiber facilities.

Abstract: A modified cutinase is disclosed. The cutinase has the modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of asparagine at position 181 with alanine, or substitutions of asparagine at position 181 with alanine and phenylalanine at position 235 with leucine. The modified enzyme has improved PET-hydrolytic activity, and thus, the high-activity PET hydrolase is obtained, and the industrial application value of the PET hydrolase is enhanced.

Abstract: The present invention provides a backlight module, including a bottom plate, a plurality of light sources disposed on the bottom plate, one or more light regulation devices, and an optical film. The light regulation device is disposed on the bottom plate and covers at least one light source. Light generated by the light source is emitted out to reach the light regulation device, and the light regulation device regulates the light. The optical film is disposed on a side, opposite to the light source, of the light regulation device.

Abstract: A backlight module including a light source, an optical wavelength conversion film, a first group of optical films, and a second group of optical films is provided. The light source is adapted to emit a first light. The optical wavelength conversion film is adapted to convert the first light into a second light with a different wavelength. The first group of optical films is disposed between the light source and the optical wavelength conversion film. The optical wavelength conversion film is disposed between the first group of optical films and the second group of optical films, wherein a ratio of a transmittance of the second group of optical films for the second light to a transmittance of the first group of optical films for the first light is larger than or equal to 45%. Thus, the backlight module has a uniform light-emitting color.

Abstract: A display device includes a backplate and a supporting member. The backplate has a positioning hole formed thereon. The positioning hole includes a first area and a second area arranged along a first direction; an average width of the second area in a direction perpendicular to the first direction is smaller than an average width of the first area in the direction perpendicular to the first direction. The supporting member includes a base, a positioning shaft and an engaging protrusion disposed on a bottom face of the base, wherein the positioning shaft includes an axle and a flange portion connected to an end of the axle. The flange portion passes through the first area so that the axle extends into the positioning hole; when the axle moves along the first direction to the second area, the flange portion interferes with a periphery of the second area, the engaging protrusion contacts against an inner wall of the first area to prevent the axle from moving back to the first area.

Abstract: A backlight module including a carrier plate, a plurality of light sources, at least one low reflective portion, and a modulation film is provided. The carrier plate has a carrier surface carrying the light sources while the low reflective portion is disposed on the carrier surface between an outer light source and a side edge of the carrier plate. The reflectance of the low reflective portion is less than that of the carrier surface. The modulation film is disposed above the light sources while the low reflective portion has a projection area on the modulation film. The projection area has a lower normalized transmission ratio comparing to adjacent areas along an extending direction of the side edge of the carrier plate.

Abstract: A display device includes a light source having a light emitting side, a partition plate disposed adjacent to the light emitting side and having light-emitting through holes distributed thereon, and a display panel having a light incident bottom surface and disposed at an opposite side of the partition plate with regard to the light source; the light incident bottom surface faces the partition plate. The light incident bottom surface has a first and a second area, the first and the second area project on the partition plate, respectively, to form a first and a second projection area. The first and the second area are away from the first and the second projection area by a first and a second average distance smaller than the first average distance. An average pitch of the light-emitting through holes in the first projection area is greater than that in the second projection area.
