20080263276 | METHOD AND APPARATUS FOR EVALUATING AND IMPROVING DISK ACCESS TIME IN A RAID SYSTEM - Techniques for improving access time in data storage systems are disclosed. These techniques can be used to prevent undesirable access delays that are often experienced in conventional storage systems. “Slow-access” can be defined as an access operation that does not successfully complete within a predetermined amount of time. The “slow-access” time can, for example, be defined based on a system requirement, specification, or a particular need of a specific application. As such, when detected “slow-access” indicates a potential performance problem that can manifest in undesirable effects. A data storage system is evaluated for potential performance problems by scanning it for “slow-access.” In addition, preventative measures are taken to prevent occurrence of a “slow-access” once it has been identified. These measures can prevent the undesirable effects experienced in conventional storage systems. This also means that specific system or application requirements can be certified and met. | 10-23-2008 |

End-users of the system are humans and items can be any objects such as songs, books, and other users. One aspect of the system is a process used to map an item's quantitative and textual data into a position in the visualization, e.g., a two or three dimensional space. Using transformation matrices canonical correlation analysis (CCA) and a specific item's quantitative and textual data, the system projects an item onto the visualization and uses ratings and spatial positions to assign reputation values to each end-user and their textual responses to facilitate efficient browsing and rating of items and viewing of patterns, trends, and insights as they emerge. | 04-17-2014 |

20140212766 | BLOCK COPOLYMER BATTERY SEPARATOR - The invention herein described is the use of a block copolymer/homopolymer blend for creating nanoporous materials for transport applications. Specifically, this is demonstrated by using the block copolymer poly(styrene-block-ethylene-block-styrene) (SES) and blending it with homopolymer polystyrene (PS). After blending the polymers, a film is cast, and the film is submerged in tetrahydrofuran, which removes the PS. This creates a nanoporous polymer film, whereby the holes are lined with PS. Control of morphology of the system is achieved by manipulating the amount of PS added and the relative size of the PS added. The porous nature of these films was demonstrated by measuring the ionic conductivity in a traditional battery electrolyte, 1M LiPF | 07-31-2014 |
