  • Patent number: 9665594
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data. In one aspect, a method includes detecting at a kernel a plurality of operations, each of a particular type from a plurality of types, to be performed on a respective data item; and generating respective entries in a delta store in response to the detected plurality of operations wherein each entry for a data item includes a marker attribute corresponding to the operation type of the plurality of types.

  • Patent number: 9558122
    Abstract: In an example implementation, a method includes receiving an indication to reclaim memory from a cache, the cache including a plurality of data buckets each configured to store one or more records and corresponding access bits. The method also includes selecting a data bucket from the cache, and processing the selected data bucket. Processing the selected data bucket includes determining access bits of the selected data bucket that are clear, and expunging data records corresponding to those access bits from the cache. Processing the selected data bucket also includes determining access bits of the selected data bucket that are set and do not correspond to records relevant to outstanding requests by a process utilizing the cache, and clearing those access bits. The method also includes repeating selecting and processing data buckets until a stop criterion is satisfied.

  • 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.

  • Publication number: 20150363704
    Abstract: This disclosure relates to service discovery using a dynamically configurable Bloom filter. According to some embodiments, various parameters of the Bloom filter may be determined by a first wireless device. The parameters may include a number of services advertised using the Bloom filter, a false positive rate of the Bloom filter, a set of hash functions used with the Bloom filter, and/or a size of the Bloom filter. The Bloom filter may be generated according to the determined parameters. The Bloom filter, along with some or all of the parameters of the Bloom filter, may be transmitted by the first wireless device. A second wireless device may use the Bloom filter as part of a service discovery process to determine whether or not a desired service is available via the first wireless device.

  • Patent number: 8943026
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data. In one aspect, a method includes receiving a user input to present a visual representation of a first prior state of a file system; generating the first visual representation of a first prior state of the file system at a first time in the past according to a first virtual file system corresponding to that first time; presenting the first visual representation, where the first virtual file system is a reduced representation of the file system at that first time; receiving a user input to present a second visual representation of a second prior state of the file system at a second time in the past according to a second virtual file system corresponding to that second time; and presenting the second visual representation.

  • Patent number: 7024045
    Abstract: The present invention provides a method and apparatus for a bandwidth adaptive image compression/decompression scheme. In one embodiment, the present invention uses a special protocol between the sender and the receiver to measure the latency of the connection. This protocol and its result are sent and received at an interval based on a dynamic feedback loop algorithm. Based on the results of the protocol, a compression scheme is chosen. This scheme uses CPU time conservatively, and also transmits the most interesting data first. In another embodiment, the present invention throws away data that is repetitious, especially when the connection is down for a short period of time. In yet another embodiment of the present invention, measurements are taken for the perceptual degradation of the image for various compression schemes, and the results are supplemented with the results of the protocol to choose a viable compression/decompression scheme.

  • Patent number: 6842182
    Abstract: The present invention varies the highlight color of a highlighted display area such that the salience of the highlighted display area remains constant to a user as the highlighted display area varies. A perceptual highlight color is determined based upon the total amount of highlighted display area and the background color of the non-highlighted display area and applied to text selected to be highlighted by a user as well as to text already highlighted on the display. In other embodiments, the perceptual highlight color can be based upon the total amount of highlighted display area and the text color of the text in the highlighted display area, and the total amount of the highlighted display area, the background color of the non-highlighted display area, and the text color.

  • Publication number: 20040205191
    Abstract: One embodiment of the present invention provides a system that facilitates initiating a communication session with a computing device. The system operates by first detecting the presence of the computing device through a first communication channel, and then initiating a communication session between the computing device and a server through the second communication channel. Next, the system transfers the state of an existing communication session between the server and a client to the computing device through the second communication channel, so that the computing device can take over the existing communication session with the server in place of the client.

  • Publication number: 20040005005
    Abstract: One embodiment of the present invention provides a system to facilitate image difference transmission for images in a video system. The system operates by receiving a video stream that includes a sequence of images. The system transforms a first frame of the sequence of images using a transform function to create a first transformed image. Note that this transform function places the image salience in the larger coefficients. The system also transforms a second frame using the same transform function to create a second transformed image. The system then subtracts the second transformed image from the first transformed image to create a difference-transformed image. The coefficients are arranged in order of size, from larger to smaller. Smaller coefficients, that are less than a specific threshold, are removed from the difference-transformed image so that this difference-transformed image can be stored and transmitted with reduced bandwidth while maintaining image salience.
