9 results about "Oxygen decrease" patented technology

This invention discloses a method for dynamic monitoring of dissolved oxygen and identification of oxidation risks throughout the entire fermentation process of specialty berry wines. For seven berry species—blueberry, raspberry, mulberry, blackberry, black chokeberry, red dragon fruit, and blackcurrant—dissolved oxygen data is systematically collected at 13 key stages, including crushing, fermentation, filtration, fining, aging, cold treatment, and bottling, to create a "dissolved oxygen dynamic spectrum" for each variety. By analyzing the peak dissolved oxygen levels and their rates of change, crushing, fining, cold treatment, and bottling are identified as four high-risk oxidation stages. Furthermore, based on the rate of dissolved oxygen decrease after crushing, the seven berry species are categorized into three types: oxidation buffering, oxidation consuming, and rapid oxygen consuming. This invention achieves a multi-variety, full-chain systematic assessment of oxidation risks, providing a quantitative basis for precise oxidation control in specialty berry wines.

This invention adopts a necklace-style, imperceptible wearing design, which has the advantages of high sensitivity, anti-interference, automatic classification, and long battery life, and is suitable for long-term continuous monitoring and forward-looking early warning of sleep apnea in the home.

The application discloses a multi-rotor intelligent unmanned plane, and relates to the technical field of unmanned planes, which comprises an unmanned plane body, and side plates are fixedly connected to the two sides of the unmanned plane body. The multi-rotor intelligent unmanned plane is provided with a first safety block, a second safety block and a safety air bag. Inert gas in a gas cylinder enters a connecting head inside through a pipeline, enters an air bag cover inside through a connecting pipe, enters an air bag cover inner cavity through a gas hole, enters a first driving air bag inside through another connecting pipe, and the first driving air bag pushes a baffle to move out of a storage cavity. At this time, another connecting pipe enters the safety air bag inside, the safety air bag bounces out of the storage cavity, the safety air bag is rapidly inflated, the top and the bottom of the unmanned plane body are protected, the unmanned plane is protected when the unmanned plane falls, and thus loss can be reduced as much as possible. The battery is arranged in a chamber in the air bag cover filled with inert gas, oxygen is isolated, and loss is reduced.
