Patent number: 10645940Abstract: 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.Type: GrantFiled: October 2, 2019Date of Patent: May 12, 2020Assignee: Zhejiang University of TechnologyInventors: Yuting Ding, Xuxia Zhou, Zhigang Ke, Shulai Liu, Shichen Zhu, Fei Lv, Jianhua Liu

Patent number: 7944089Abstract: An uninterruptible power supply module is provided. The uninterruptible power supply module comprises an input terminal, a direct-current voltage source, a control module, a control arm-bridge module, an inductive element, a power source selection switch, and a switch element. The switch element is turned on before the power source selection switch is connected to the inductive element so that the direct-current voltage supplied by the direct-current voltage source is modulated by the control arm-bridge module to generate an output alternating current voltage to the load. And the switch element is turned off, i.e. not conducting electricity, after the power source selection switch is connected to the inductive element and the direct-current voltage source. Thereby, the use life of the power source selection switch element and the reliability of the uninterruptible power supply module are both increased.Type: GrantFiled: January 16, 2009Date of Patent: May 17, 2011Assignee: Delta Electronics, Inc.Inventors: Yan-Song Lu, Fei Lv, Jing-Tao Tan, Jian-Ping Ying
