  • Patent number: 10360939
    Abstract: Disclosed herein are embodiments of a heat-assisted magnetic recording (HAMR) device comprising a waveguide and a near-field transducer (NFT) coupled to the waveguide. The NFT comprises a core layer comprising an insulator, a first metal layer adjacent to the core layer, and a second layer adjacent to the first metal layer, wherein the second layer comprises a material that is substantially mechanically and thermally stable and thereby functions as a hard jacket to mitigate deformation of the NFT. The first metal layer may comprise a plasmonic metal, such as gold. The second layer may comprise tungsten, chromium, or a dielectric material.

  • Publication number: 20190017921
    Abstract: Methods and systems for efficient contour and gating in flow cytometry are provided. Event data is compressed to reduce the number of points needed to represent polygon contours for the event data. Selection of a level within the contour then causes the generation of a gate. This allows limited resource devices, such as touchscreen wireless devices, to render and gate flow cytometry data in a resource efficient manner.

  • Publication number: 20180349226
    Abstract: The described embodiments set forth techniques for preserving clone relationships between files at a computing device. In particular, the techniques involve identifying clone relationships between files in conjunction with performing operations on the files where it can be beneficial to preserve the clone relationships. The operations can include, for example, preserving clone relationships between files that are being copied from a source storage device (that supports file cloning) to a destination storage device that supports file cloning. Additionally, the operations can include preserving clone relationships when backing up and restoring files between a source storage device (that supports file cloning) and a destination storage device that does not support file cloning. In this manner, the various benefits afforded by the clone relationships between files can be retained even as the files are propagated to destination storage devices that may or may not support file cloning.

  • Publication number: 20180349133
    Abstract: The embodiments set forth a technique for restoring a computing device to an operable state when a software update renders the computing device inoperable. According to some embodiments, a snapshot of a file system volume is automatically generated prior to executing the software update. When an issue is detected with the software update—e.g., the computing device freezes, the computing device cannot boot into an operable mode, etc.—the computing device can (1) automatically enter into a restoration mode, and (2) restore the file system volume to its previous state in accordance with the snapshot. In this manner, the issues caused by the software update are entirely mitigated, and the computing device can transition back into an operable state.

  • Publication number: 20180349227
    Abstract: The embodiments set forth techniques for performing incremental backups of a source file system volume (FSV) managed by a source computing device. According to some embodiments, the source computing device can be configured to generate a current snapshot of the source FSV, where the current snapshot complements a previous snapshot of the source FSV (e.g., established during a previous backup). In some cases, to free up storage space, the data for files belonging to the source FSV can be stripped from the previous snapshot (where metadata for the files remains intact). Next, the source computing device can generate, within a destination storage device, a second snapshot of a destination FSV (that corresponds to the source FSV). In turn, the source computing device identifies changes made to the source FSV based on the current snapshot and the previous snapshot, and reflects the changes within the second snapshot of the destination FSV.

  • Patent number: 9600582
    Abstract: When objects are shared by one user with another user, objectionable content, if identified as such, can be blocked from being shared, while the remainder of the shared objects can be accessed by the other user. Functions that allow sharing of content are implemented so as prevent sharing of objectionable content with another user, while allowing other content to be shared. If a group of files or objects is shared, then the presence of objectionable content in one object in the group results in that objectionable content not being shared, but the remaining files or objects are still shared. A graphical user interface for accessing the storage system, whether by providers or recipients of shared content, can selectively render information about objects with objectionable content.

  • Patent number: 9542423
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data are disclosed. In some implementations, visual representations of files are generated for presentation in a backup user interface. The visual representations are generated from sparse file system metadata stored on the computing device, thus allowing faster navigating of the backup user interface. During a restore operation, the metadata can be used to retrieve the items from their physical storage locations. In some implementations, when the storage capacity of a backup storage device exceeds a threshold, the data for the N oldest backups are replaced with sparse file system metadata, which can be used to generate visual representations for presentation in the backup user interface.

  • Patent number: 9509238
    Abstract: Torque ripple produced by a traction motor of an electric vehicle when the motor produces torque from a motor current is compensated for by modifying operation of the motor according to a difference between an expected position of the motor to produce a desired torque from the current and the actual position of the motor when producing torque from the current.

  • Publication number: 20160206543
    Abstract: Methods and compositions are provided for mitigating the irritation of mammalian skin cells, protecting cell viability and/or enhancing cell-cell junction, thus improving skin barrier function. The compositions contain combinations of acetyl hexapeptides and a cosmetically and/or pharmaceutically acceptable carrier. Carriers that lend a liquid crystalline aspect to the compositions are beneficial.

  • Patent number: 8930915
    Abstract: Provided is a method for mitigating the effects of an application which crashes as the result of supplemental code (e.g., plug-in), particularly a plug-in from a source other than the source of the operating system of the device or the source of the application that crashes. The method includes executing the application. As the application is running, it may be monitored to determine if normal execution of instructions ceases. When that occurs, the system will make a determination if code from a supplemental code module was the cause of the crash, and will make an evaluation if that supplemental code module is from a source other than the source(s) of the operating system and application in question. In some implementations, remedial steps may be provided, such as providing information on subsequent executions of the application.
