Abstract: The present disclosure relates to a fluid system for a sample processor and a sample processor including the fluid system. The fluid system includes a sample line, a processing fluid line, a vacuum line, and an air pump. The sample line communicates a sample container with a sample port of a flow cell unit. The processing fluid line communicates a sheath fluid container with a processing fluid port of the flow cell unit. The vacuum line is in communication with the flow cell unit. The air pump includes a first output port and a second output port. Pressurized gas is generated at the first output port, and the first output port is in communication with the sample container and the sheath fluid container. A vacuum is generated at the second output port, and the second output port is in communication with a vacuum port of the flow cell unit through the vacuum line.

Abstract: A human facial identification method and system are disclosed, which belong to the mode identification technical field and intend to improve veracity of human facial identification implemented in outdoor environment. The human facial identification method includes: driving a group of infrared lamps by a high frequency pulse signal to generate infrared backlight, collecting identified human facial features in irradiation of the infrared backlight, comparing the collected identified human facial features with a human facial template to complete the human facial identification. A human facial compensation method and system are also disclosed, which are intend to improve luminance of infrared backlight. The technical solutions are mostly applied to the human image identification field.
