  • Patent number: 12284168
    Abstract: A multifunction peripheral (MFP) includes user selectable functions that call home applications on the device that direct it to work cooperatively with cloud service providers. To avoid requiring users to login to each cloud service each time they use it, they are registered with an authorization server to establish and grant identity and authorization tokens. When a user logs in to an MFP, they are redirected to login to the authorization server which then sends tokens to the MFP identifying the user and their permissions and licenses. Home applications associated by the tokens are displayed for selection. Each time a home application using a cloud service is selected, a background application sends the user's session tokens with a service request to an associated cloud service resource server. The resource servers processes authenticated requests and return the result to the MFP which completes the selected home application function.

  • Publication number: 20240428045
    Abstract: A system captures and utilizes expert knowledge in artificial intelligence. The system includes a knowledge capture module for extracting expert knowledge from subject matter experts in a conversational format and a knowledge management module for cataloging and summarizing the extracted knowledge. The system also includes a digital subject matter expert (dSME) module for ingesting the cataloged knowledge and using it to guide users in building AI models. A chatbot interacts with a user and selects the appropriate dSME module that is relevant to the user request. The system attempts to answer the user request based on the dSME module. If the dSME module lacks knowledge to solve the problem, the system uses a set of tools, for example, internet based search engine to solve the problem.

  • Patent number: 12001736
    Abstract: A system and method for providing alternative authentication modes in multifunction peripherals includes supplying mobile device management and application authentication to multifunction peripherals without such capabilities. A pluggable authorization module is installed on an incompatible multifunction peripheral by providing a user login on a devices idle screen with an login URL. A user's login credentials are verified by an authentication server that returns an associated username and access permissions once verified. This information is used by the pluggable authorization module to generate a temporary multi-function device services user supplied with the retrieved access permissions. The user can then use the multifunction device services via the temporary user. The temporary user is deleted once the user logs out.

  • Publication number: 20240141378
    Abstract: The present disclosure describes methods and systems for use in the production of adeno-associated virus (AAV) particles, including recombinant adeno-associated virus (rAAV) particles. The production process and system use Baculoviral Expression Vectors (BEVs) and/or Baculoviral Infected Insect Cells (BIICs) in the production of AAV particles (e.g., rAAVs) which allow for the controlled expression of AAV structural (e.g., capsid) proteins, such as VP1, VP2, and VPS and the controlled expression of AAV nonstructural (e.g., replication) proteins, such as Rep78 and Rep52.

  • Patent number: 11931528
    Abstract: A catheter configured to dynamically compensate for the impact of internal and external forces that act upon the catheter during use is disclosed. The catheter may include sensors configured to measure received forces on control cables that extend within the catheter. A controller, coupled to the sensors, may record received force measurements associated with a working position of a distal end of the catheter. The controller may monitor subsequently received forces to identify force variances that may deflect the distal end of the catheter from its working position and may apply a driving force to one or more of the control cables to minimize the force variances. Monitoring received forces during use and applying compensating drive forces may reduce deflection of the distal end of the catheter, increasing the accuracy and precision of an annuloplasty procedure while minimizing potential damage to cardiac tissue.

  • Publication number: 20240089392
    Abstract: A system and method for authenticating direct network print jobs includes registering users for direct printing with a cloud print server. Registration information is stored as a mapping record includes a user name, their computer name and an email address associated with their cloud storage account. When a user sends a print job directly to an MFP at its network address, the MFP checks with the cloud server to determine if the user is registered in accordance with their associated mapping record. If so, a permissions list for that user is checked to determine whether the user has print permission. The user's direct print is then released and their document is printed.

  • Patent number: 11879953
    Abstract: A method for evaluating gastric and upper small intestine motility and emptying in a gastrointestinal tract of a subject using magnetic resonance imaging includes administering a contrast agent to the subject; acquiring, using an MRI system, a set of MR data from the subject using a three-dimensional volumetric pulse sequence. The volumetric pulse sequence has a temporal resolution and a spatial resolution configured to facilitate measurement of volumetric and motility parameters. The method further includes reconstructing a set of images using the set of MR data, segmenting each image in the set of images to isolate a region of interest in the gastrointestinal tract of the subject, determining at least one volumetric and motility parameter based on the set of segmented images, and generating a report indicating the at least one volumetric or motility parameter.

  • Publication number: 20230359942
    Abstract: A system makes predictions using a machine learning model combined with a knowledge model. The system provides input data to a knowledge model and a machine learning based model. The machine learning based model is trained to make predictions based on input data. The system provides the outputs of the machine learning based model and the knowledge model to an ensemble model configured to combine results of the knowledge model and the machine learning based model. The system can be used for several applications. For example, the system may classify an input text based on a hierarchy of categories. The system may perform fault detection in time series data by identifying an anomaly data point and predicting whether the anomaly data point is a fault.
