Publication number: 20250054510Abstract: The present invention relates to the technical field of bionic covert underwater acoustic communication, and specifically relates to a feature extraction-based imitated marine mammal sound signal covertness scoring method. The scoring method combines feature engineering to extract six universal features of a marine mammal sound signal from the perspective of human hearing and a signal waveform, and uses these features to obtain a second bionic signal covertness score through a weight coefficient formula. The covertness scoring method can characterize intrinsic information of the bionic signal in more detail from more perspectives of the signal to more accurately evaluate a difference between the bionic signal and a real signal, and the obtained score value can more intuitively describe the quality of the bionic signal covertness.Type: ApplicationFiled: October 30, 2024Publication date: February 13, 2025Inventors: Jingjing Wang, Shuai Jiang, Meng Wang, Runqi Cao, Yufang Li, Jiaming Jiang, Xinghai Yang

Patent number: 11316838Abstract: A method for transmitting router security information, applied in a router, includes: transmitting, to a terminal requesting to acquire router security information, a generated link of a local area network for transmitting the router security information; receiving an access request initiated by the terminal through a network address to which the link of the local area network is pointed; and, returning, through the local area network, a response to the access request to the terminal, the response containing encrypted router security information. The encrypted router security information can therefore be transmitted by a local network established for transmitting security information by a router. In this security information transmission mode, the possibility of remotely acquiring router security information is eliminated. Moreover, the situation where the router security information is transmitted on the cloud is also avoided, and the security of privacy information of terminal devices is improved.Type: GrantFiled: March 30, 2020Date of Patent: April 26, 2022Assignee: BEIJING XIAOMI MOBILE SOFTWARE CO., LTD.Inventors: Guizhen Yang, Yufang Li, Daokuan Liu, Dian Fan

Patent number: 5332721Abstract: An improved technique for the fabrication of thallium-based superconducting oxides, and particularly Tl:Ba:Ca:Cu:O 2223 oxides, is described which allows production of very pure superconductors (>95% 2223 phase) having excellent structural characteristics. The method of the invention involves first forming a self-sustaining body of starting oxides and subjecting this body to a sintering technique wherein the temperature of the body is gradually raised to a maximum level of about 850.degree.-930.degree. C., followed by maintaining the body at this temperature for a period of about 48 hours. The body is then slowly cooled to avoid distortion and loss of superconducting character. Most preferably, the sintering is a two-stage operation, wherein the body is first heated a relatively low rate (e.g., 1.degree.-10.degree. C./min.) to a temperature of about 650.degree.-750.degree. C., followed by faster heating at a higher rate to achieve the maximum sintering temperature.Type: GrantFiled: October 21, 1992Date of Patent: July 26, 1994Assignees: Midwest Superconductivity, Inc., The University of ArkansasInventors: Ying Xin, Zhengzhi Sheng, Yufang Li
