摘要:
A molded roofing material tile that forms a five-sided rectangular box-like structure with a central support spine running on the underside of the tile from the back side to the front side, that permits virtually free drainage of sub-tile water through an elongated weep aperture running along the back side of the tile, thereby to drain water away that would otherwise deteriorate the tile and the underlayment. The tile has rabbeted sides that permit overlapping with side adjacent tiles laid in a roofing course. The tiles are fastened by conventional fasteners that run through reinforced fastener posts at the rear corners of the tile, and do not require application of special adhesive. No special alternative embodiment is required as an initial course of tile nearest the eaves of the building.

A time optimizing communications system and method is provided because “loose lips sink ships”. Orders get “do by” parameters, “deliver by” times and may be broken into parts according to “do by” parameters, and/or by prioritization for delivery only when the recipient has the need-to-know. Time sensitive and most secret parts are communicated just in time, some data may be sent at randomized times that may bias traffic on communications infrastructure towards bandwidth optimization. Reducing risk of decryption by adversaries occurring quickly enough to frustrate the purposes of orders. Parts may be broken into data blocks and routed and/or stored randomly. An array of pointers records details of their creation and/or storage locations to provide a key for retrieving data blocks and/or reconstructing messages; timing is managed according to mission needs, and priorities. May also reduce peak demand on communications bandwidth.

A method, system, apparatus, and/or device for cleaning a check valve of a pressurized pipe system. The method, system, apparatus, and/or device may include a first check valve attached between pipes of a pressurized pipe system. The first check valve may include a housing, a disc attached to an interior cavity of the housing, a port formed in the housing, and a second check valve attached to the port. The disc may be configured to move between an open position to allow a first fluid to flow from a first pipe to a second pipe and a closed position to stop the first fluid from flowing from the second pipe to the first pipe. The second check valve may be configured to allow the second fluid to flow into the first check valve and stop the first fluid from flowing out of the second check valve.

In an apparatus according to one embodiment of the present disclosure, a communications link comprises a first device and a second device communicating with each other via the communications link at a plurality of different speeds. However, prior to communicating via the communications link for the first time at a second speed, the first device and second device complete a first training cycle at the second speed. Further, during this first training cycle for the second speed, the first training cycle for the second speed will pause before the first training cycle at the second speed completes, and the first device and second device communicate at a first speed for a period of time before returning to the paused first training cycle at the second speed. When the paused first training cycle for the second speed continues, the first training cycle for the second speed will continue where it had paused.

Mechanisms are provided for optimizing files while allowing application servers access to metadata associated with preoptimized versions of the files. During file optimization involving compression and/or compaction, file metadata changes. In order to allow file optimization in a manner transparent to application servers, the metadata associated with preoptimized versions of the files is maintained in a metadata database as well as in an optimized version of the files themselves.

A data de-duplication system is used with network attached storage and serves to reduce data duplication and file storage costs. Techniques utilizing both symlinks and hardlinks ensure efficient deletion file/data cleanup and avoid data loss in the event of crashes.

Mechanisms are provided for optimizing multiple files in an efficient format that allows maintenance of the original namespace. Multiple files and associated metadata are written to a suitcase file. The suitcase file includes index information for accessing compressed data associated with compacted files. A hardlink to the suitcase file includes an index number used to access the appropriate index information. A simulated link to a particular file maintains the name of the particular file prior to compaction.

A method, system, apparatus, and device provides alert information to a user of a device. In response to an alert notification of an alert, one or more alert geographical tiles of interest that are affected by the alert of a plurality of geographical tiles are determined; one or more location-enabled devices each having a location that falls within an alert geographical tile of the one or more alert geographical tiles are determined; a portion of the alert is retrieved from an alert database and processed to generate a media version of the alert; an alert text notification of the alert having the text portion of the alert, an alert identifier of the alert, a reference identifier for the media version of the alert, the one or more alert geographical tiles, and the one or more one or more device identifiers for each of the one or more devices is constructed; the one or more device identifiers for each of the one or more devices, the alert text notification and the alert identifier of the alert is retrieved and the alert text notification is transmitted to the one or more devices corresponding to the retrieved one or more device identifiers.
摘要:
Embodiments generally disclosed herein include a computer-implemented method for monitoring and correlating network traffic data associated with a primary network that is in communication with a plurality of secondary networks. The method generates a network traffic data set by monitoring network traffic between the primary network and the plurality of secondary networks. The method also determines a mapping of network connectivity by monitoring inter-network routing information between the primary network and the plurality of secondary networks. In addition, the method generates a traffic measurement data set by monitoring network utilization statistics between the primary network and the plurality of secondary networks. With the collected data sets, the method then calculates a relational network mapping between the primary network and the plurality of secondary networks by correlating the network traffic data set, the mapping of network connectivity, and the traffic measurement data set.
