Patent number: 12530770Abstract: The present disclosure relates to a method. The method includes accessing automatically segmented liver data and automatically segmented spleen data from a patient. The automatically segmented liver data is used to determine a liver attenuation and the automatically segmented spleen data is used to determine a spleen attenuation. A liver-to-spleen attenuation ratio is determined from the liver attenuation and the spleen attenuation. A hepatic steatosis determination is made from the liver-to-spleen attenuation ratio.Type: GrantFiled: September 6, 2023Date of Patent: January 20, 2026Assignees: Case Western Reserve University, Emory University, University Hospitals Cleveland Medical CenterInventors: Gourav Modanwal, Sadeer Al-Kindi, Jonathan Walker, Rohan Dhamdhere, Sanjay Rajagopalan, Anant Madabhushi

Patent number: 11804912Abstract: One example includes a self-synchronizing TDD antenna system. The system includes an antenna system to communicate transmit and receive signals and an antenna control circuit coupled to a user communication system. The antenna control circuit includes a transmission line measurement circuit to determine signal loss through a transmission line cable coupled to the antenna system and an amplitude adjustment circuit to adjust amplitude of the transmit and/or receive signals based on the signal loss. A transmit detection circuit monitors signal power of the transmit signal, and a controller switches the amplitude adjustment circuit from a receive mode to a transmit mode in response to the monitored signal power exceeding a predetermined threshold. In the receive mode, the adjustment circuit applies a receive amplitude adjustment to the receive signal, and in the transmit mode the adjustment circuit applies a transmit amplitude adjustment to the transmit signal.Type: GrantFiled: April 3, 2020Date of Patent: October 31, 2023Assignee: VIASAT, INC.Inventor: Jonathan Walker

Patent number: 11734919Abstract: A flexible computer architecture for performing digital image analysis is described herein. In some examples, the computer architecture can include a distributed messaging platform (DMP) for receiving images from cameras and storing the images in a first queue. The computer architecture can also include a first container for receiving the images from the first queue, applying an image analysis model to the images, and transmitting the image analysis result to the DMP for storage in a second queue. Additionally, the computer architecture can include a second container for receiving the image analysis result from the second queue, performing a post-processing operation on the image analysis result, and transmitting the post-processing result to the DMP for storage in a third queue. The computer architecture can further include an output container for receiving the post-processing result from the third queue and generating an alert notification based on the post-processing result.Type: GrantFiled: November 16, 2022Date of Patent: August 22, 2023Assignee: SAS Institute, Inc.Inventors: Daniele Cazzari, Hardi Desai, Allen Joseph Langlois, Jonathan Walker, Thomas Tuning, Saurabh Mishra, Varunraj Valsaraj

Patent number: 11070675Abstract: A method and device are presented for delivering a voicemail message to a voicemail system associated with a user device. A first session initiation protocol (SIP) session may be initiated with a first SIP server. Upon receiving a provisional response from the first SIP server, a second SIP session may be initiated with a second SIP server. A response indicating that a call has been successfully established using either the first SIP session or the second SIP session is received. The SIP session in which the call was not established is terminated. Audio from the voicemail system received via the SIP session in which the call was established is analyzed to determine when the voicemail system may receive the voicemail message. The voicemail message is transmitted to the voicemail system via the SIP session in which the call was established.Type: GrantFiled: August 5, 2020Date of Patent: July 20, 2021Assignee: MAGNIFY TELECOM, LLCInventors: Lauro Ruiz, Jonathan Walker, John Oesterle, Kris Droge
