20100312800 | Segment deduplication system with compression of segments - A system for storing compressed data comprises a processor and a memory. The processor is configured to receive a compressed segment. The compressed segment is determined by breaking a data stream, a data block, or a data file into one or more segments and compressing each of the one or more segments. The processor is further configured to determine whether the compressed segment has been previously stored, and in the event that the compressed segment has not been previously stored, store the compressed segment. The memory is coupled to the processor and configured to provide the processor with instructions. | 12-09-2010 |

20090044338 | Coverings for Viscoelastic Foam Mattresses - Covers for mattresses having a reclining surface of viscoelastic foam have a fabric body with a first surface disposed in engagement with the reclining surface; an opposite, second surface disposed for engagement by a person reclining upon the cover; and at least one air flow region defined by the fabric body for enhanced circulation of air between the reclining surface of viscoelastic foam and an opposed skin surface of the person reclining upon the cover. | 02-19-2009 |
20090186548 | Composite Fabrics - A hybrid composite fabric garment includes a first fabric portion and a second fabric portion. The first fabric portion includes a first inner fabric layer, a first outer fabric layer, and a first barrier layer disposed therebetween. The first barrier includes a first nonwoven membrane and has a first predetermined air permeability. The second fabric portion includes a second inner fabric layer, a second outer fabric layer, and a second barrier layer disposed therebetween. The second barrier layer includes a second nonwoven membrane and has a second predetermined air permeability substantially greater than the first predetermined air permeability. | 07-23-2009 |
20100088818 | Coverings For Viscoelastic Foam Mattresses - Covers for mattresses having a reclining surface of viscoelastic foam have a fabric body with a first surface disposed in engagement with the reclining surface; an opposite, second surface disposed for engagement by a person reclining upon the cover; and at least one air flow region defined by the fabric body for enhanced circulation of air between the reclining surface of viscoelastic foam and an opposed skin surface of the person reclining upon the cover.
