20100151414 | PERIODONTAL POCKET IRRIGATOR - A periodontal irrigator flushes out bacteria at the base of a periodontal pocket. The periodontal pocket irrigator is a handheld device that can be used by patients in their homes to irrigate periodontal pockets. The device includes a handle, a liquid container, and a plunger or other mechanism for dispensing Listerine, water, antibacterial fluid, or various prescriptions from the container, to treat periodontal disease. The container can be easily removed for cleaning. The liquid contents can be dispensed from the container through a removable tip either manually or by a solenoid or other motor. A lever can be used to move the plunger. Dispensing can be continuous, or limited to predetermined doses. The dispensing tip is angled, and can be oriented in more than one direction with respect to the handle. The device can include a light to illuminate the mouth, as periodontal disease frequently starts in the interproximal area of the molars in the darker parts of the mouth. | 06-17-2010 |
20130122453 | THERAPEUTIC GUM IRRIGATOR - A therapeutic gum irrigator is provided for subgingival periodontal irrigation with a chemotherapeutic fluid. The irrigator includes a housing surrounding at least a portion of the irrigator, a reservoir connected to the housing to retain the fluid, and a cannula configured for subgingival periodontic insertion in fluid communication with the reservoir. The irrigator further includes a neck connected to the housing and separating the reservoir from the cannula. A pump in fluid communication with the reservoir and the cannula includes a displacing element movable between first and second positions and a biasing element that biases the displacing element to the first position. A lever connected to the housing can mechanically move the displacing element to the second position, expelling a predefined volume of the fluid through the cannula. The biasing element causes the displacing element to return to the first position upon release of the thumb lever by the user. | 05-16-2013 |

20150378767 | USING ACTIVE/ACTIVE ASYNCHRONOUS REPLICATED STORAGE FOR LIVE MIGRATION - Examples perform live migration of VMs from a source host to a destination host. The disclosure changes the storage environment, directly or through a vendor provider, to active/active synchronous and, during migration, migrates only data which is not already stored at the destination host. The source and destination VMs have concurrent access to storage disks during migration. After migration, the destination VM executes, with exclusive access to the storage disks, and the system is returned to the previous storage environment (e.g., active/active asynchronous). | 12-31-2015 |
20150378771 | USING A DELTA QUERY TO SEED LIVE MIGRATION - Examples perform live migration of objects such as VMs from a source host to a destination host. The disclosure exposes the contents of the storage disk at the destination host, compares the storage disk of the destination host to the source host, and during migration, migrates only data which is not already stored at the destination host. The source and destination VMs have concurrent access to storage disks during migration. After migration, the destination VM executes, with exclusive access to the storage disks. | 12-31-2015 |
20150378783 | LIVE MIGRATION WITH PRE-OPENED SHARED DISKS - Examples perform live migration of virtual machines (VM) from a source host to a destination host. The live migration performs time-consuming operations before the source host is stunned, reducing the downtime apparent to users. Some examples contemplate pre-copying memory from the source VM to the destination VM, and the opening of disks on the destination VM before stunning the source VM. | 12-31-2015 |
20150378785 | USING ACTIVE/PASSIVE ASYNCHRONOUS REPLICATED STORAGE FOR LIVE MIGRATION - The disclosure describes performing live migration of objects such as virtual machines (VMs) from a source host to a destination host. The disclosure changes the storage environment, directly or through a vendor provider, to active/passive synchronous or near synchronous and, during migration, migrates only data which has not already been replicated at the destination host. The source and destination VMs have concurrent access to storage disks during migration. After migration, the destination VM executes with exclusive access to the storage disks, and the system is returned to the previous storage environment of active/passive asynchronous. | 12-31-2015 |
20150378831 | USING A RECOVERY SNAPSHOT DURING LIVE MIGRATION - Examples perform live migration of VMs from a source host to a destination host using destructive consistency breaking operations. The disclosure makes a record of a consistency group of VMs on storage at a source host as a fail-back in the event of failure. The source VMs are live migrated to the destination host, disregarding consistency during live migration, and potentially violating the recovery point objective. After live migration of all of the source VMs, consistency is automatically restored at the destination host and the live migration is declared a success. | 12-31-2015 |
20150378847 | MAINTAINING CONSISTENCY USING REVERSE REPLICATION DURING LIVE MIGRATION - Examples maintain consistency of writes for a plurality of VMs during live migration of the plurality from a source host to a destination host. The disclosure intercepts I/O writes to a migrated VM at a destination host and mirrors the I/O writes back to the source host. This “reverse replication” ensures that the CG of the source host is up to date, and that the source host is safe to fail back to if the migration fails. | 12-31-2015 |

20090254582 | METHOD AND SYSTEM FOR STORAGE REPLICATION - Consistent replicas of a data object are created using a replication protocol that includes an opportunistic replication phase followed by a consistent replication phase. During the opportunistic replication phase, dirty regions are selected from the data object included in a primary computer and copied to a data object replica included in a secondary computer according to a selection heuristic. During the consistent replication phase, an immutable image of the data object is created by the primary computer and the remaining dirty regions are copied from the immutable image of the data object to the data object replica to create a consistent replica of the data object. | 10-08-2009 |
20090254693 | METHOD AND SYSTEM FOR GENERATING CONSISTENT SNAPSHOTS FOR A GROUP OF DATA OBJECTS - Snapshots that are consistent across a group of data objects are generated. The snapshots are initiated by a coordinator, which transmits a sequence of commands to each storage node hosting a data object within a group of data objects. The first command prepares a data object for a snapshot. After a data object has been successfully prepared, an acknowledgment is sent to the coordinator. Once all appropriate acknowledgments are received, the coordinator sends a command to confirm that a snapshot has been created for each data object in the respective group. After receiving this confirmation, the coordinator takes action to confirm or record the successful completion of the group-consistent snapshot. | 10-08-2009 |
