  • Patent number: 10438019
    Abstract: A second operating system accessing resources from an external service. A method includes sending an anonymized request, for an anonymized user corresponding to an authorized user, for resources, through a broker. A request for proof indicating that the anonymized user is authorized to obtain the resources is received from the broker. As a result, a request is send to a first operating system for the proof that the anonymized user is authorized to obtain the resources. Proof is received from the first operating system, based on the anonymized user being associated with the authorized user, that the anonymized user is authorized to obtain the resources. The proof is provided to the broker. As a result, the resources are obtained by the second operating system from the service.

  • Patent number: 10408904
    Abstract: A magnetic resonance imaging (MRI) system (500), the system includes at least one controller (510) which performs a modified rotated slab excitation (mROSE) sequence for volume selection to exclude portions of a subject under exam which are within the scanning volume and outside of a field-of-view (FOV) so as to reduce foldover artifacts which originate from the excluded portions of the subject under exam, where the mROSE sequence performs volume excitation based upon either optimized symmetrical, minimum-phase, or stretched minimum-phase radio-frequency (RF) pulses in a sagittal plane and encodes the scanning volume in a coronal plane. The controller also performs a chemical-shift sequence including a modified DIXON (mDIXON) sequence for substantially uniform fat/water separation within a FOV which lies within the scanning volume; and/or acquires echo information for reconstructing at least a part of an image.

  • Publication number: 20190158497
    Abstract: Providing access control by a first operating system. A method includes receiving at the first operating system, from the second operating system, a request for a bounding reference to a set having at least one resource. A bounding reference for the set is obtained. The bounding reference comprises a reference created from a first operating system resolvable reference to the set. The method further includes providing the obtained bounding reference for the obtained provided bounding reference to the second operating system. A request, including the obtained bounding reference and an identifier identifying the second operating system for the set, is received from the second operating system. The obtained bounding reference and the identifier identifying the second operating system are evaluated. As a result of evaluating the obtained bounding reference and the identifier identifying the second operating system, a resource control action is performed.

  • Publication number: 20170353496
    Abstract: A host operating system running on a computing device monitors network communications for the computing device to identify network resources that are requested by the computing device. The host operating system compares requested network resources against security policies to determine if the requested network resources are trusted. When an untrusted network resource is identified, the host operating system accesses the untrusted network resource within a container that is isolated from the host operating system kernel using techniques discussed herein. By restricting access to untrusted network resources to isolated containers, the host operating system is protected from even kernel-level attacks or infections that may result from an untrusted network resource.

  • Publication number: 20170299677
    Abstract: A guide map is created for use in placing a spectroscopic single voxel in a region of interest in single voxel magnetic resonance spectroscopy. An anatomical planning image of the region of interest is obtained through MRI. A spectroscopy voxel is stepped across the region of interest, characteristics of the magnetic field used in the MRI are measured at each location of the imaging voxel, and a guide-FWHM map indicative of the homogeneity/inhomogeneity of the magnetic field over the region of interest is derived using the measurements. The guide map is created by overlaying the guide-FWHM map on the anatomical planning image. A spectroscopic single voxel of a size corresponding to that of the spectroscopy voxel is placed within the region of interest as per the guide map. Then spectral data is acquired from the region of interest confined to the single voxel.

  • Publication number: 20170279805
    Abstract: The techniques and systems described herein improve security and improve connection reliability by providing a framework for an application to communicate its intent to an authority service so that the authority service can enforce networking security requirements. In various examples, an intent to access a resource over a network is received and queries are sent to resolve a network connection that enables access to the resource. Information for the resource is then collected and stored together in a trusted and secure environment. For instance, the information can include proxy data or can include hostname data. A ticket can be created based on the information. The ticket can be used to establish and maintain a secure network connection to the resource.

  • Publication number: 20120143928
    Abstract: Various embodiments of systems and methods for file system transaction log flush optimization are described herein. An optimizer is working as an intelligent processing unit, autonomously determining the best possible time to flush all collected transaction data modifications to the file system when operating under high load, or flushing each modification separately under low load. When operating under high load, batches of data modifications are collected and written together to the file system in a single write operation, thus decreasing the number of write operations and achieving better utilization of the system resources.
