Abstract: An electronic device comprises a display apparatus, a photographing apparatus, and a lifting apparatus. The photographing apparatus receives, through the first channel or a second channel, a first stream on instruction triggered by a first application. The second channel is a channel between the display apparatus and the photographing apparatus, and the first stream on instruction is used to instruct the photographing apparatus to collect an image and output the collected image to the first application. The photographing apparatus reports a first stream on state to a proxy module in the display apparatus through the first channel. The proxy module in the display apparatus controls, based on the first stream on state, the lifting apparatus to lift the photographing apparatus. The photographing apparatus after being lifted starts to collect an image, and outputs the collected image to the first application through the second channel.

Abstract: The present invention relates to a method and a device for ship-borne freezing of marine products after treated by highly activated water and nondestructive sensing of ice crystals. Through treating the seawater with atmospheric plasma in a certain atmosphere and introducing the tail gas from plasma reactor into the seawater in tail gas collecting device, the highly activated water is obtained. After cooling by the ship-borne refrigeration system, the cooled highly activated water can be used to cool and sterilize the captured marine products timely. During the following freezing processes, both the ultra-high frequency (UHF) electromagnetic field system and pulsed ultrasonic monitoring system are applied simultaneously, which can not only effectively reduce the size of ice crystals and the juice loss of the frozen products during thawing, but also inhibits the thermal effect of electromagnetic field.

Abstract: The present invention provides a method for extracting heat-sensitive Antarctic krill oil comprising the following steps. Firstly, frozen Antarctic krill is thawed and minced; a surfactant is added to the minced Antarctic krill to form a supercritical micelle system; extract the Antarctic krill multiple times after pressurizing and liquefying mixed gases; at the same time, a low-carbon alcohol solvent is added to strip the material in the critical micelle; after the extraction is completed, the extractant is removed; the extraction product and the residue after the extraction are subsequently collected; the heat-sensitive Antarctic krill oil can be obtained by high-speed centrifugal separation of the oil-water mixed extraction product. The present method has the advantages of simple operation, low extraction pressure and high safety. The extraction method of gas pressure liquefaction is completed under low temperature sealing conditions.
