Patent number: 11085689Abstract: A control method for a refrigerator comprises driving a first cooling fan to cool a first storage chamber; adjusting a damper to cause cold air to simultaneously flow through first and second cold-air passages; adjusting a damper to reduce the opening angle of the first cold-air passage, when the temperature of a high-temperature chamber reaches a value smaller than or equal to a second reference temperature for the high-temperature chamber; adjusting a damper to reduce the opening angle of the second cold-air passage, when the temperature of a low-temperature chamber reaches a value smaller than or equal to a second reference temperature for the low-temperature chamber; and driving a second cooling fan to cool a second storage chamber. When a predetermined time elapses or the sensed temperature of the high-temperature chamber reaches a first set temperature, the damper is adjusted to increase the opening angle of the first cold-air passage.Type: GrantFiled: March 24, 2017Date of Patent: August 10, 2021Assignee: LG Electronics Inc.Inventors: Hosan Kim, Sunghee Kang, Jindong Kim, Jeongwon Park, Namgyo Lee, Jihyun Im, Namsoo Cho, Yonghyeon Cho

Patent number: 10273440Abstract: Systems and methods for growing microbes and biofilms on a hydrogel in a controlled environment. The system can have a cup, and a liner with the liner inserted into the cup and a hydrogel inserted into the liner. The cup, liner, and hydrogel assembly can be placed into a containment tray. The hydrogel can be sterilized before being placed into the containment tray. A lid can seal the cup, liner, and hydrogel into the containment tray. A lid can have inoculations ports, or can be made out of a self-sealable material keeping the inside environment sterilized and free of contaminants. The hydrogel can be inoculated with microbes through the inoculations ports, and incubated for a period of time at a set temperature to allow the microbes, and biofilms time to grow. After being grown the microbes and biofilms can be separated from each other allowing for both microbes and biofilm to be separately tested.Type: GrantFiled: November 5, 2015Date of Patent: April 30, 2019Inventors: Jeffry B.
