Patent number: 11941340Abstract: Aspects of the invention include methods, systems, and computer program products for integrated circuit development using cross-hierarchy antenna condition verification. A method includes obtaining a design of a hierarchical macro distributed between multiple files for an integrated circuit and analyzing, by a design verification tool, a route between at least one child macro and at least one pin of the hierarchical macro as defined in the files. The method further includes determining, by the design verification tool, a plurality of connection characteristics of the at least one child macro and the at least one pin forming the route and calculating, by the design verification tool, an antenna condition for the route based on the connection characteristics. The design of the hierarchical macro is adjusted to remove a violation of an antenna rule based on determining that the antenna condition of the route violates the antenna rule.Type: GrantFiled: August 16, 2021Date of Patent: March 26, 2024Assignee: International Business Machines CorporationInventors: Michael Alexander Bowen, Gerald L Strevig, III, Amanda Christine Venton, Robert Mahlon Averill, III, Adam P.

Patent number: 11941179Abstract: A system and method for displaying images of internal anatomy includes an image processing device configured to provide high resolution images of the surgical field from low resolution scans during the procedure. The image processing device digitally manipulates a previously-obtained high resolution baseline image to produce many representative images based on permutations of movement of the baseline image. During the procedure a representative image is selected having an acceptable degree of correlation to the new low resolution image. The selected representative image and the new image are merged to provide a higher resolution image of the surgical field. The image processing device is also configured to provide interactive movement of the displayed image based on movement of the imaging device, and to permit placement of annotations on the displayed image to facilitate communication between the radiology technician and the surgeon.Type: GrantFiled: December 13, 2021Date of Patent: March 26, 2024Assignee: NuVasive, Inc.Inventors: Robert E.

Publication number: 20240092143Abstract: A system for detecting external leaks in a cabin of a vehicle includes sensors and onboard vehicle controls disposed on the vehicle. Control modules of the system have processors, memory, and input/output (I/O) ports. The I/O ports communicate with the sensors and onboard vehicle controls. The control modules execute program code portions stored memory. The program code portions include first and second algorithm portions. The first algorithm portion receives data from the sensors and controls and determines that the data from the sensors and controls meets initialization threshold values. When the data from the sensors and controls meets the threshold values, the second algorithm portion generates a cabin leak detection output including: a first output, a second output, or a third output. The first output indicates a large leak, the second output indicates no leak, and the third output indicates that a small leak has been detected.Type: ApplicationFiled: September 20, 2022Publication date: March 21, 2024Inventors: Dhruv Patel, Joseph F.

Patent number: 11907970Abstract: Adaptive control of exposure. A proportional exposure cap is a maximum fraction applicable to a recipient's total viewable attention in a time window. The total viewable attention represents all viewable advertising content which will be provided to the recipient. A notification of availability of an opportunity to expose a specified recipient to advertising content is received during the time window. The specified recipient's consumed viewable attention is detected. The specified recipient's total viewable attention for the time window is predicted. Responsive to the maximum fraction of the specified recipient's predicted total viewable attention for the time window being greater than the consumed viewable attention of the specified recipient, content is sent to the specified recipient and the consumed viewable attention is updated.Type: GrantFiled: February 6, 2023Date of Patent: February 20, 2024Assignee: Quantcast CorporationInventors: Seph Zdarko, Ryan Lei Hin Chan, David Alexander Grant

Patent number: 11899813Abstract: Techniques are disclosed relating to multi-factor authentication for data security. In some embodiments, a computer system receives, from a user device, a database operation request that specifies a set of query data, where the computer system supports multiple different security levels requiring different subsets of a set of authentication factors supported by a known device of a user of the user device. Various devices may determine current contextual information for the database operation request, where the contextual information indicates the set of query data. In some embodiments, the computer system selects, based on the current contextual information, a security level from the multiple different security levels. In some embodiments, the computer system revokes, based on the selected security level, access privileges of the user for accessing a database corresponding to the database operation request.Type: GrantFiled: June 24, 2022Date of Patent: February 13, 2024Assignee: Salesforce, Inc.Inventors: Marla Hay, Joshua David Alexander
