A melon seed separation unit comprises a support, and a material collection portion, an air separation portion, a seed collection container, a peel collector and a base which are fixed along the support sequentially from top to bottom. The material collection portion is integrally in the shape of a circular arc, and a seed passage is arranged in the bottom of the material collection portion. An air source pipe is fixed to the top end of the support, penetrates through the material collection portion and penetrates out from the bottom of the seed passage. The air separation portion comprises a circular arc air separation chamber and a collection chamber which are communicated through a first air separation passage and a second air separation passage, the first air separation passage is arranged axially along the air separation portion and opposite to the air source pipe, and the second air separation passage is annually arranged around the first air separation passage. The melon seed separation unit is simple to operate, quick and effective and good in separation effect, the material collection portion, the air source pipe and the air separation portion are integrated, physiological property of the seeds is unaffected as soaking is omitted, no mechanical damage is caused to the seeds, germination vitality of the seeds is unaffected, and storage and utilization of seeds are facilitated.

The invention discloses a screening device for gingkoes. The device includes a rack body (1) and at least one layer of transmission device arranged on the rack body (1). Each transmission device comprises a spiral shaft (2) and an optical shaft (3) arranged in parallel to each other. The spiral shafts (2) are rotatably connected to the rack body (1), and the optical shafts (3) are fixedly connected with the rack body (1). The optical shafts are provided with first grooves (31) in the radial directions of the optical shafts, and the first grooves (31) are opposite to the spiral shafts (2). Through the screening device for gingkoes, gingkoes can be screened and classified into different sizes and various specifications, and the shell removal rate of the shell removal process is thus improved.

The invention relates to a method for detecting obstructive sleep apnea syndrome. The method includes the following steps: using a photoelectric plethysmography (PPG) sensor for oxygen saturation information collection, using a snore sensor for snore information collection, and using a respiration signal sensor for respiration information collection; processing collected respiration information to acquire an average respiration rate and average respiration strength; processing collected snore information to acquire average snore strength within a time period before current moment; performing high-pass filtering on collected PPG signals; according to an artificial intelligent decision-making theory, building a fuzzy element set by the respiration information, the snore information and the oxygen saturation information after being processes, establishing a subordinate function, creating a fuzzy grade list and a fuzzy function set, building a multi-factor evaluation matrix and judging whether a person has the obstructive sleep apnea syndrome or not according to a maximum subordinate principe. The invention further relates to a system for detecting the obstructive sleep apnea syndrome.
