| 20090172273 | METHOD AND SYSTEM FOR DISK STORAGE DEVICES REBUILD IN A DATA STORAGE SYSTEM - In a data storage system, failed disk drives are switched temporarily off-line to be quickly rebuilt by executing a journaling/rebuild algorithm which tracks the updates to the failed disk drive into a journal structure created in a non-volatile memory. The journal information is used to update those data sections of the disk drive affected by updates after the disk drive is failed. The journal information is stored in bit maps indicating which portions of the disk drive have been updated with new data while the disk was failed. As an option, the system permits verification of data consistency on the data section of the disk drive which have not been affected by the updates. The journaling/rebuild of failed disks is applicable, among others, to RAID data storage systems. | 07-02-2009 |
| 20140172930 | FAILURE RESILIENT DISTRIBUTED REPLICATED DATA STORAGE SYSTEM - A failure resilient distributed replicated data storage system is described herein. The storage system includes zones that are independent, and autonomous from each other. The zones include nodes that are independent and autonomous. The nodes include storage devices. When a data item is stored, it is partitioned into a plurality of data objects and a plurality of parity objects calculated. Reassembly instructions are created for the data item. The data objects and parity objects are spread across all nodes and zones in the storage system. Reassembly instructions are also spread across the zones. When a read request is received, the data item is prepared from the lowest latency nodes according to the reassembly instructions. This provides for data resiliency while keeping the amount of storage space required relatively low. | 06-19-2014 |

The storage system includes zones that are independent, and autonomous from each other. The zones include nodes that are independent and autonomous. The nodes include storage devices. When a data item is stored, it is partitioned into a plurality of data objects and a plurality of parity objects are calculated. Reassembly instructions are created for the data item. The data objects, parity objects and reassembly instructions are spread across nodes and zones in the storage system according to a policy for the data item. When a zone is inaccessible, a virtual zone is created and used until the intended zone is available. When a read request is received, the data item is prepared from the lowest latency nodes according to the reassembly instructions, and a virtual zone is accessed in place of a real zone when the real zone is inaccessible. | 06-19-2014 |

| 20090129872 | High-reach insulation application system and method - This invention relates generally to the application of a sprayed insulation mixture, and more particularly to an apparatus and method for applying the sprayed mixture in high reach areas of extended elevation and removing any excess mixture therefrom. In one embodiment of a system for spraying an insulation mixture into a cavity and removing any excess mixture therefrom, the system preferably comprises a lift defining upper end lower ends, with the upper end of the lift being adjustably movable between lowered and raised positions. An insulation applicator is located on the lift proximal to the upper end for spraying the insulation mixture into the cavity. The applicator may be rotatably connected to the lift and driven to move in a reciprocating, sweeping motion. A scrubber is also located on the lift, preferably above the applicator, for removing or scrubbing any excess insulation from the cavity. A vacuum inlet is preferably located on the lift below the applicator for receiving any stray or “fly-off” insulation from the applicator and the excess insulation removed from the cavity by the scrubber. A gauge may also be located on the lift for maintaining a predetermined spray distance between the applicator and the cavity. A driven elevation mechanism is operably associated with the lift for adjustably moving the upper end of the lift between the lowered and raised positions. A control is operably associated with the insulation applicator, scrubber, vacuum inlet and driven elevation mechanism to control the function of each component. | 05-21-2009 |
| 20090173174 | Sprayed insulation application system having variably locatable components - This invention relates generally to sprayed insulation application systems, and more particularly to systems that utilizes a sole power source to directly or indirectly drive the system's multiple components independent of the location of a power-take-off. In one embodiment of the invention, the system utilizing a sole power source comprises at least one power-take-off operably associated with the power source. An insulation blower and a hydraulic drive are operably associated with the at least one power-take-off. An electrical generator and a vacuum fan are operably associated with the hydraulic drive, with at least one control regulating the operable association of the generator and the vacuum fan with the hydraulic drive. In another embodiment of the invention, the hydraulic drive is operably associated with the power-take-off, with the generator, vacuum fan and insulation blower operably associated with the hydraulic drive. The electrical generator, driven by the generator hydraulic motor in fluid communication with the hydraulic drive, preferably provides electrical energy to the scrubber, and to the at least one liquid heater and/or the electrically powered lift, if utilized within the system, via electrical conduits. A pump may be optionally driven by the hydraulic drive or energized by the generator. | 07-09-2009 |

| 20080243444 | Method of predicting and communicating the performance of an installed building component based on the transient hygrothermal behavior of the component - A method of predicting and communicating transient hygrothermal behavior of an installed building component in a building wherein an interior environment of the building is materially affected by an environment exterior of the building, includes: defining a performance characteristic of the building component that is affected by transient hygrothermal behavior of the building component; defining exterior and interior climatic factors that affect the defined performance characteristic wherein the interior climatic factors are a function of the exterior climatic factors; and defining one or more non-climatic factors that affect the defined performance characteristic. Inputting these factors into a transient hygrothermal simulation software program to create a software model for performing simulations which predict changes in the defined performance characteristic, as a function of time, that are compared with a threshold performance characteristic value, to provide a user guide. | 10-02-2008 |
