Abstract: Location-synchronous averaging of connected vehicle data is provided. Connected vehicle data, including events occurring to a plurality of vehicles driving along roadways and location coordinates at which the respective events occurred, is aggregated. A kernel density estimation is performed to smoothly aggregate neighboring event counts. The locations of conditions along the roadways are indicated as being where the aggregate neighboring event counts have a value over a predefined threshold.

Abstract: A heat management system for air-cooled engines suitable to power yard care equipment or vehicles. The system may generally comprise an engine, a blower configured to blow ambient cooling air across the engine, and an exhaust system comprising an exhaust header and a muffler. The exhaust header has an inlet end which receives heated exhaust gas from the engine and an outlet end fluidly coupled to the muffler. An air control baffle is configured to redirect a portion of the cooling air from the blower towards the exhaust header and the muffler to enhance cooling the exhaust system. The system may further include an outermost protective shield exposed to equipment operators and an inner heat barrier or shield located between the muffler and protective shield. The system is designed to ameliorate both radiative and convective sources of heat transfer to maintain the protective shield at temperatures below established industry standards.

Abstract: The described embodiments set forth techniques for providing a backup progress estimate for a backup of a source file system volume (FSV). The techniques involve determining, for the source FSV, a backup size during performance of backup operations. The operations can include determining the backup size based on a number of files on the source FSV. Additionally, the operations can include copying files of the source FSV and/or propagating corresponding files of a destination FSV to a location of the backup of the source FSV on a destination storage device and updating one or more metrics using a number of files and/or a number of bytes copied and/or propagated to the backup. In this manner, a progress indication for the backup may be determined based on the one or more metrics responsive to files and/or directories of the source file system volume being stored on a destination storage device.

The gas manifold is configured to provide a bidirectional flow path through the fuel cap. The fuel cap connector is integrated with or coupled to the gas manifold, and the fuel cap connector is configured to connect the fuel cap to the gas manifold. The base is configured to support the gas manifold and provide at least a first gas input to the gas manifold and through the fuel cap via the bidirectional flow path. The removable cover is configured to be removably connected to the gas manifold and provide at least a second gas input to the gas manifold and through the fuel cap via the bidirectional flow path.

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.

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.
