Publication number: 20240121267Abstract: A hierarchical structure constructor constructs a hierarchical structure that comprises nodes associated with feature sets patterns of URLs. Nodes at each depth are labelled as malicious, benign, or mixed for corresponding to URLs that are malicious, benign, or malicious and benign that match the corresponding patterns. Malicious feature set patterns are extracted from malicious nodes in the hierarchical structure. A URL analyzer operates inline by logging traffic sessions, extracting URLs from the logs, and matching the extracted URLs with the malicious feature sets patterns extracted from the hierarchical structure. The hierarchical structure is periodically updated with known malicious/benign URLs to improve quality of malicious URL detection.Type: ApplicationFiled: October 6, 2022Publication date: April 11, 2024Inventors: Yubao Zhang, Fang Liu, Peng Peng, Oleksii Starov

Patent number: 11424093Abstract: Within a direct current hybrid circuit breaker (DC HCB), a commutation unit (CU) is provided in a semiconductor switch path in series with a semiconductor switch to facilitate opening the DC HCB. The semiconductor switch path is connected in parallel with a mechanical switch path that includes a mechanical switch. The CU is a controlled voltage source which applies a reverse biased voltage on the semiconductor switch path. The CU causes the current through the mechanical switch to ramp down while the current through the semiconductor switch ramps up to a supply current. The CU maintains the current through the mechanical switch to remain at a zero vale by compensating for the voltage drop across the semiconductor switch and the self-inductance of the semiconductor switch path. The mechanical switch can open without current and against no recovery voltage.Type: GrantFiled: October 24, 2019Date of Patent: August 23, 2022Assignee: The Florida State University Research Foundation, Inc.Inventors: Michael Steurer, Fang Peng
