  • Publication number: 20190251996
    Abstract: A method includes receiving a write request to write a current data block to a Shingled Magnetic Recording (SMR) storage device. In response, the current data block is written to a current physical block in an open zone of the SMR storage device. A corresponding copy of the current data block is written to a nonvolatile memory. A determination is made of whether a wandering write error occurred during the writing of the data to the open zone. In response to the wandering write error occurring, for each of the number of written physical blocks in the open zone that have the corresponding copy in the nonvolatile memory, the data in the physical block is validated using the corresponding copy. In response to validation, the data in the corresponding copy is written as corrected data for the physical block to a new zone in the SMR storage device.

  • Patent number: 10379742
    Abstract: A storage system writes an object across zones of a set of zones (“zone set”). Each zone of a zone set is contributed from an independently accessible storage medium. To create a zone set, the storage system arbitrarily selects disks to contribute a zone for membership in the zone set. This results in a fairly even distribution of zone sets throughout the storage system, which increases fault tolerance of the storage system. Although disk selection for zone set membership is arbitrary, the arbitrary selection can be from a pool of disks that satisfy one or more criteria (e.g., health or activity based criteria). In addition, weights can be assigned to disks to influence the arbitrary selection. Although manipulating the arbitrary selection with weights or by reducing the pool of disks reduces the arbitrariness, this evenly distributes zone sets while accounting for client demand and/or disk health.

  • Patent number: 10365671
    Abstract: During operation, a facility may utilize many sensors, such as cameras, to generate sensor data. Some of these sensors may be housed within protective enclosures. The enclosures may be inside specially controlled environments, such as refrigerators, freezers, and so forth. During operation of the facility, moisture may accumulate on these enclosures, impairing the ability of the camera to acquire an image through the window. Described are devices to selectively heat a viewable area of the window such that moisture accumulation is reduced with minimal power use.

  • Publication number: 20190225952
    Abstract: The present disclosure provides variant Pol6 polymerase polypeptides, compositions comprising the Pol6 variant polypeptides, and methods for using the variant Pol6 polypeptides for determining the sequencing of nucleic acids, for example, by nanopore sequencing. The variant Pol6 polymerases possess decreased rates of dissociation of template from the polymerase-template complex, which result in increased processivity relative to the parental Pol6 polypeptides from which they are derived.

  • Publication number: 20190177658
    Abstract: The present invention relates to novel cleaning compositions that are substantially free of cocamide diethanolamine. In an aspect of the invention, the compositions utilize a surfactant system and coupling agents as a replacement for the rheology modifier cocamide diethanolamine. The combination of a surfactant system and coupling agents can be used as a replacement for traditional rheology modifiers and foaming agents which are under regulatory pressure while providing concentrated liquid cleaning compositions with a viscosity of 400 cps or less. In another aspect the invention relates to novel cleaning compositions such as pot and pan soaking compositions, dishwashing compositions, food and beverage foaming cleaners, vehicle cleaning and the like suitable for use in hard water, which can be solid or liquid. The invention further relates to methods of making these compositions, and to methods employing these compositions.

  • Patent number: 10127199
    Abstract: The visual similarity between fonts is determined using visual descriptors of character images in the fonts. A model used to generate the visual descriptors may include a set of letterforms, keypoint locations on each letterform, and detail shapes at zero, one, or more detail areas on the letterform. In some instances, the model may also set forth one or more geometric measurements. Based on the model, a visual descriptor may be generated for a character image from a font by identifying a letterform of the character image, identifying keypoint locations on the character image, and identifying a detail shape at any detail areas on the character image. Additionally, the visual descriptor may include any geometric measurement defined by the model. The visual similarity between two fonts may be determined as a function of the differences between pairs of visual descriptors for the fonts that correspond with the same letterform.

  • Publication number: 20180192629
    Abstract: A protective harness for a fully-rigged fishing rod during transport and/or storage, comprised of two hollow tubes that are closed at one end and open on the other end. The tubes are connected by an elastic cord attached near the open end of each tube. One tube slides over the upper (tip) portion of the rod, and the other tube slides over the lower (handle) portion of the rod, with the elastic cord stretching between the two tubes and maintaining tension, thus creating a protective harness that adheres to the fishing rod. This easy-on easy-off protective harness may be used on a one-piece or a multiple-piece fishing rod while it is fully rigged with tackle, acting as a lure guard as well as a rod protector. The tubes may be transparent to maximize viewing of the contents. When not in use, the tubes nest inside one another for convenient storage.

  • Publication number: 20170351951
    Abstract: Non-limiting examples of the present disclosure describe query classification to identify appropriateness of a query. A query may be received by at least one processing device. A deep neural network (DNN) model may be applied to evaluate the query. A vector representation may be generated for query based on application of the DNN model, where the DNN model is trained to classify queries according to a plurality of categories of appropriateness. The DNN model may be utilized to classify the query in a category of appropriateness based on analysis of the vector representation. In one example, auto-complete suggestions for the query may be filtered based on the classification of the category of appropriateness. In another example, classification of the query may be provided to an entry point. In yet another example, a response to the query is managed based on the classification of the query. Other examples are also described.
