Abstract: Disclosed is a new identifier allocation approach for allocating repository object identifiers beyond a maximum number usually allowed for a single repository. The new identifier allocation approach includes an enhanced identifier structure in which a portion usually reserved for a docbase identifier is modified to combine with a partition identifier. The actual docbase identifier is stored in a server configuration file. When the maximum number of object identifiers has been allocated, a new partition is created and a sequence table is updated with a new entry that reflects the new partition. A new repository object identifier is allocated using the docbase identifier combined with the new partition identifier. In this way, more than 4 billion objects per object type can be addressed uniquely within a docbase by creating new partitions. This new approach is very unique and flexible in accommodating both on premises and multi-tenant environments.

Abstract: A first cellular base station transmits a configuration message to a reporting device installed on a high-speed vehicle. The configuration message specifies one or more parameters of a Doppler measurement report. The reporting device performs one or more first Doppler measurements on the first base station and/or one or more second Doppler measurements on a second base station. The reporting device transmits the Doppler measurement report to the first and/or second base stations. The Doppler measurement report may be used by the first and/or second base stations to perform Doppler pre-compensation on transmissions to the reporting device.

Abstract: The present disclosure relates to a system and techniques for preventing corruption of snapshot data by limiting the visibility of committed data. To do this, the system may maintain an index that indicates the highest transaction identifier value such that no future commits will have a transaction identifier less than or equal to the indexed transaction identifier value. In embodiments, if a read is performed, only transactions having a transaction identifier less than or equal to the index value can be read. Each time that a transaction is committed, the index value is updated to the transaction identifier for the transaction having the highest transaction identifier without any intermediary transactions.

Abstract: Techniques are disclosed relating to managing virtual data sources (VDSs), including creating and using VDSs. A virtual data source manager (VDSM) that is executing on a computer system may receive a VDS creation request to create a particular VDS. The VDS creation request may include information that is usable to identify a data origin of the particular VDS and an ingestion routine. The VDSM may use the ingestion routine to create the particular VDS that includes a bitmap index that is representative of data stored at the origin. In response to a data request corresponding to the origin, the particular VDS may be used to initiate a query to the particular VDS for data without accessing the origin. The VDSM may further maintain various software plugins that are executable to perform corresponding functions in relation to the VDSM and the VDSs managed by the VDSM.

Abstract: Register banks are used to allow for fast beam switching in a phased array system. Each beam forming channel is associated with a register bank containing M register sets for configuring such things as gain/amplitude and phase parameters of the beam forming channel. The register banks for all beam forming channels can be pre-programmed and then fast beam switching circuitry allows all beam forming channels across the array to be switched to use the same register set from its corresponding register bank at substantially the same time, thereby allowing the phased array system to be quickly switched between various beam patterns and orientations. Active power control circuitry may be used to control the amount of electrical power provided to or consumed by one or more individual beam forming channels such as to reduce DC power consumption of the array and/or to selectively change the effective directivity of the array.

Abstract: A centralized auditing system receives an audit block containing one or more audit files generated by an audit agent running in an audited device. The audit block additionally stores a first digital signature corresponding to a previous audit block, and a second digital signature generated based at least on the one or more audit files and the first digital signature. After receiving the audit block, the auditing system verifies the integrity of the received audit block based on the second digital signature stored in the audit block and/or the first digital signature corresponding to the previous audit block. In response to verifying the integrity of the received audit block, the auditing system adds the received audit block to an audit register. Moreover, the auditing system adds the one or more audit files included in the audit block to an audit database.

Abstract: Provided is a transmitter for musical instrument and a mode switching method thereof. A transmitter for musical instrument which is mounted on an electric guitar determines the electric guitar is in a not-in-use state when a continuation time in which a square sum of accelerations output from a three-axis acceleration sensor is smaller than a power-saving threshold value is longer than a power-saving transition time, and the transmitter transitions from a normal mode to an energy-saving mode. On the other hand, when the accelerations in the energy-saving mode becomes equal to or greater than a release threshold value from a state of being smaller than the release threshold value or becomes equal to or smaller than the release threshold value from a state of being greater than the release threshold value, the electric guitar is returned from the energy-saving mode to the normal mode.

Abstract: A client machine writes to and reads from a virtual disk on a remote storage platform. Metadata is generated and stored in replicas on different metadata nodes of the storage platform. A modified log-structured merge tree is used to store and compact string-sorted tables of metadata. During file storage and compaction, a consistent file identification scheme is used across all metadata nodes. A fingerprint file is calculated for each SST (metadata) file on disk that includes hash values corresponding to regions of the SST file. To synchronize, the fingerprint files of two SST files are compared, and if any hash values are missing from a fingerprint file, then the key-value-timestamp triples corresponding to these missing hash values are sent to the SST file that is missing them. The SST file is compacted with the missing triples to create a new version of the SST file. The synchronization is bi-directional.

Abstract: Techniques and solutions are described for implementing virtual table schemas. A virtual table schema includes a logical pointer that is used to target a table that includes data and is defined according to the virtual table schema. Values assigned to the logical pointer can be used to target tables at different locations, such as in-memory storage or in dynamic storage of a database management system. The dynamic storage includes an in-memory buffer cache and persistent storage. The logical pointer can be updated to point to the in-memory storage or the dynamic storage, including based on use statistics. Similarly, a table having data for the virtual table can be transitioned between the in-memory buffer cache and the persistent storage, including based on use statistics for the virtual table. A value for the logical pointer can be updated when the table is transferred between the in-memory buffer cache and the dynamic storage.

Abstract: Data intake and query system (DIQS) instances supporting applications including lower-tier, focused, work group oriented applications, are tailored to display the metrics for the needs of the user. An interface caused by operation of an entity monitoring system (EMS) operating in conjunction with the lower-tier DIQS displays the monitored entities as individual representations. The user selects a metric and a metric threshold. The EMS causes a display of an interface having a representation for each monitored entity. Each representation includes a metric value and indicates an entity status based on the metric value and the threshold. The user can dynamically change the threshold on the interface for easy visualization of aggregation of monitored entities to determine the performance of the infrastructure. The interface also provides the user with the ability to select an entity and click through to the entity analysis workspace for more detailed information.

Abstract: In an example, first entities are extracted from user profiles. Second entities are extracted from content information associated with content item. User-associated metrics associated with the first entities are determined based upon the user profiles and/or content events. First vector representations of the first entities and second vector representations of the second entities are processed to generate an attention distribution array. Each value of the attention distribution array represents, for a user interested in an entity of the first entities, a proportion of (i) entity-specific activity, of the user, related to an entity of the second entities relative to (ii) an entirety of activity of the user. An inferred activity distribution array is generated by applying the user-associated metrics to the attention distribution array. A filtered subset of activity distribution values is generated by pruning values from the inferred activity distribution array.
