Patent number: 12316672Abstract: This disclosure describes a technique to fingerprint TLS connection information to facilitate bot detection. The notion is referred to herein as “TLS fingerprinting.” Preferably, TLS fingerprinting herein comprises combining different parameters from the initial “Hello” packet send by the client. In one embodiment, the different parameters from the Hello packet that are to create the fingerprint (the “TLS signature”) are: record layer version, client version, ordered TLS extensions, ordered cipher list, ordered elliptic curve list, and ordered signature algorithms list. Preferably, the edge server persists the TLS signature for the duration of a session.Type: GrantFiled: October 24, 2023Date of Patent: May 27, 2025Assignee: Akamai Technologies, Inc.Inventors: David Senecal, Andrew Kahn, Ory Segal, Elad Shuster, Duc Nguyen

Patent number: 12257072Abstract: Provided herein are methods for in-vivo assessment of intraventricular flow shear stress, risk of hemolysis, also the location and extent of blood flow stasis regions and inside a cardiac chamber or blood vessel. Also provided herein are systems for performing such methods. Also provided herein are methods for assessing hemolysis and/or thrombosis risk in patients implanted with an LVAD. LVAD positioning and/or speed may be adjusted based on the results obtained by using methods described herein, and the risk for hemolysis and/or thrombosis can be minimized.Type: GrantFiled: September 28, 2022Date of Patent: March 25, 2025Assignee: The Regents of the University of California et al.Inventors: Juan Carlos del Alamo de Pedro, Lorenzo Rossini, Andrew Kahn, Javier Bermejo, Pablo Martínez-Legazpi, Raquel Yotti Alvarez

Patent number: 11799908Abstract: A method of bot detection in a computer network leverages a machine learning system. The machine learning system receives a fingerprint derived at a server, the server having extracted a set of transport layer security parameters received from a client and processed the set parameters into the fingerprint. Based at least in part on the fingerprint, the learning system determines whether the client is likely to be a bot as opposed to a human user. The system generates and returns to the server as score having a first value when the fingerprint is determined to be associated with a good client, and having a second value when the fingerprint is determined to be associated with a bot. Based on the score received from the machine learning system, the server takes a configured action with respect to the client.Type: GrantFiled: November 23, 2021Date of Patent: October 24, 2023Assignee: Akamai Technologies, Inc.Inventors: David Senecal, Andrew Kahn, Ory Segal, Elad Shuster, Duc Nguyen

Patent number: 11771379Abstract: The present disclosure provides methods for in-vivo assessment of the location and extent of blood flow stasis regions inside a cardiac chamber or blood vessel and systems for performing the methods. The disclosure provides methods for assessing risk of intracardiac or intravascular thrombus or of embolism originating in a cardiac chamber or vessel, and methods for assessing the need for and/or optimization of cardiac resynchronization therapy.Type: GrantFiled: June 11, 2020Date of Patent: October 3, 2023Assignees: The Regents of the University of California, Fundación para la Investigación Biomédica del Hospital Gregorio MarañóInventors: Juan Carlos del Alamo de Pedro, Lorenzo Rossini, Andrew Kahn, Javier Bermejo, Pablo Martínez-Legazpi, Raquel Yotti Alvarez

Patent number: 11709761Abstract: Embodiments provide systems and methods for performing automated browser testing on different native file types by receiving files of different types. A preview version of each file can be generated and rendered in an output file type. Generating the preview version can be performed by a preview application executed by the testing system and rendering the preview version of the first file can be performed by a browser application executed by the testing system. The output file type can be different from the received file type. For example, the received file type can be a native file type of a first application different from the browser and the output file type comprises an HyperText Markup Language (HTML) file type. A test can be executed on the rendered preview version based on one or more assertions on the first file.Type: GrantFiled: May 11, 2022Date of Patent: July 25, 2023Assignee: Box, Inc.Inventors: Andrew Kahn, Claudio Bartolini, Denali Lumma
