Patent number: 11978680Abstract: A microelectronic chip device includes a semiconductor substrate and multiple on-chip strain sensors (OCSSs) constructed on the substrate at various locations of the substrate. The OCSSs may each include multiple piezoresistive devices configured to sense a strain at a location of the various locations and produce a strain signal representing the strain at that location. A strain measurement circuit may also be constructed on the semiconductor substrate and configured to measure strain parameters from the strain signals produced by the OCSSs. The strain parameters represent the strains at the various location. Values of the strain parameters can be used for analysis of mechanical stress on the chip device.Type: GrantFiled: November 24, 2021Date of Patent: May 7, 2024Assignee: Micron Technology, Inc.Inventors: Kenneth William Marr, Chiara Cerafogli, Michele Piccardi, Marco-Domenico Tiburzi, Eric Higgins Freeman, Joshua Daniel Tomayer

Patent number: 11978225Abstract: A method includes obtaining a reference image and a target image each representing an environment containing moving features and static features. The method also includes determining an object mask configured to mask out the moving features and preserves the static features in the target image. The method additionally includes determining, based on motion parallax between the reference image and the target image, a static depth image representing depth values of the static features in the target image. The method further includes generating, by way of a machine learning model, a dynamic depth image representing depth values of both the static features and the moving features in the target image. The model is trained to generate the dynamic depth image by determining depth values of at least the moving features based on the target image, the object mask, and the static depth image.Type: GrantFiled: April 17, 2023Date of Patent: May 7, 2024Assignee: Google LLCInventors: Tali Dekel, Forrester Cole, Ce Liu, William Freeman, Richard Tucker, Noah Snavely, Zhengqi Li

Patent number: 11922668Abstract: A set of user interface tools is described facilitating asynchronous adjudication of one or more regions-of-interest in a medical image by a group of two or more graders, each of which has access to the set of tools in a workstation environment. The set of tools include (1) a feature for enabling the graders to assess the medical image and manually delineate one or more specific regions-of-interest (ROI) in the medical image, (2) a feature for assessing the ROI(s) delineated by other graders, including display of the ROI delineated by other graders; (3) dialog features for explaining and discussing the assessments, including a text feature for discussing the assessments. The dialog features and the ROIs delineated by all the graders are visible to all the graders on the workstation display as they collectively adjudicate the medical image in a round-robin manner. The set of tools further include (4) a feature for manually verifying grader agreement with the other graders' assessments.Type: GrantFiled: November 5, 2021Date of Patent: March 5, 2024Assignee: Google LLCInventors: Rebecca Ackermann, William Chen, Thad Hughes, Teagan Daly, Scott McKinney, Rory Sayres, Quang Duong, Jacob Stimes, Eric Lindley, Cristhian Cruz, Beverly Freeman

Publication number: 20240073701Abstract: Systems and methods are described herein for predicting tower downtimes in a cellular or wireless network and taking preemptive measures relative to the predicted downtime. One or more towers in a cellular network are selected to predict whether they are or are about to experience downtime. A prediction model trained to predict downtimes of towers sharing a characteristic with the one or more selected towers. Current information associated with the one or more selected towers is obtained and used in the prediction model to generate a downtime prediction for the one or more selected towers. The downtime prediction for the one or more selected towers is then provided to an administrator.Type: ApplicationFiled: August 23, 2022Publication date: February 29, 2024Inventor: Jon William Freeman Crofford

Publication number: 20230336660Abstract: Systems and method are directed towards dynamically updating a remote management system of changes in e911 records. An e911 computing system may determine if an e911 record has been deleted from a local database. In response to determining that the e911 record has been deleted, the e911 computing system notifies a management system of the e911 record being deleted. The e911 computing system may also determine if the e911 record is new. In response to determining that the e911 record is new, the e911 computing system provides the e911 record to the management system. The e911 computing system may also determine if the e911 record has changed. In response to determining that the e911 record has changed: the e911 computing system generates a table of changes to the e911 record and provides the table of changes to the management system.Type: ApplicationFiled: July 15, 2022Publication date: October 19, 2023Inventor: Jon William Freeman Crofford

Publication number: 20230337010Abstract: Embodiments are directed towards providing document change alerts in a cloud-based wireless network system. A list of a plurality of target radio frequency design sheets is obtained. One or more cloud-based folders is then search for the plurality of target radio frequency design sheets. One or more corresponding target radio frequency design sheets are identified during the search. A last-modified date of the corresponding target radio frequency design sheet is compared to a target date. In response to the last-modified date of the corresponding target radio frequency design sheet being more recent than the target date: a most recent version of the corresponding target radio frequency design sheet is maintained and an older version of the corresponding target radio frequency design sheet is archived. A modification notification is then sent to at least one user associated with the corresponding target radio frequency design sheet that changed.Type: ApplicationFiled: July 15, 2022Publication date: October 19, 2023Inventor: Jon William Freeman Crofford

Patent number: 11436839Abstract: The present disclosure provides systems and methods to detect occluded objects using shadow information to anticipate moving obstacles that are occluded behind a corner or other obstacle. The system may perform a dynamic threshold analysis on enhanced images allowing the detection of even weakly visible shadows. The system may classify an image sequence as either “dynamic” or “static”, enabling an autonomous vehicle, or other moving platform, to react and respond to a moving, yet occluded object by slowing down or stopping.Type: GrantFiled: November 2, 2018Date of Patent: September 6, 2022Assignees: TOYOTA RESEARCH INSTITUTE, INC., MASSACHUSETTS INSTITUE OF TECHNOLOGYInventors: Felix Maximilian Naser, Igor Gilitschenski, Guy Rosman, Alexander Andre Amini, Fredo Durand, Antonio Torralba, Gregory Wornell, William Freeman, Sertac Karaman, Daniela Rus
