Abstract: The present application relates to the technical field of wireless communications, and discloses a terminal location capability reporting method and device. The method comprises: an access and mobility management function (AMF) entity obtains and stores a terminal location capability of a terminal, and after a location service for a target terminal arrives, if the terminal location capability of the target terminal is stored in the AMF entity, the AMF entity transmits the terminal location capability of the target terminal to a location management function (LMF) entity, so that the LMF sets a location method for the target terminal according to the terminal location capability. In the process above, when the LMF entity needs to obtain the terminal location capability of the target terminal, the terminal location capability of the target terminal can be directly obtained from the AMF entity, and there is no need to interact with the terminal to obtain the terminal location capability.

Abstract: Provided is a fingerprint identification apparatus which includes: a micro lens array; at least one light shielding layer; a pixel unit array; and an array of filter unit groups, where each filter unit group includes at least two filter units which transmit light signals in at least two colors respectively, where the pixel unit array includes a pixel unit group corresponding to the filter unit group, at least two pixel units in the pixel unit group receive a first light signal through the at least two filter units respectively, and a pixel unit except the at least two pixel units receives a second light signal through a transparent region between the at least two filter units, or a pixel unit between pixel unit groups receives the second light signal through a transparent region between the filter unit groups. The apparatus can improve the security of identification without affecting identification effect.

Abstract: The present disclosure discloses a wood-bamboo double layer floor including a top panel and bottom panel. The top panel is long strip shape and made by the whole log. The bottom panel is made by the whole log. Wood fiber directions of the top panel are parallel to a long side of the floor. Wood fiber directions of the bottom panel are parallel or perpendicular to the long side. The top panel and bottom panel are adhered by adhesive. Patchwork opens are pieced up to each other and made around the bottom panel. Grooves are defined in the bottom panel and arranged in a row along a direction being perpendicular to the wood fiber directions of the bottom panel. bamboo strips embedded and adhered in the grooves, are matched with the grooves. And bamboo fiber directions are the same as length directions of the bamboo strips.

Abstract: The present invention relate to a methane synthesis catalyst preparation method, comprising a preparation step for a catalytic body and a prereduction step. The prereduction step comprises: calcining the catalytic body to form a nickel aluminate spinel-containing catalyst precursor; and prereducing the catalyst precursor to acquire the methane synthesis catalyst. The catalyst prepared in the preparation method can be used in high-temperature and high liquid-to-gas ratio conditions, shows performance stability, and obviates the need for a further step of high-temperature reduction during vehicle operation. Also provided is the methane synthesis catalyst precursor. The catalyst precursor contains nickel aluminate spinel.
