| 20110029730 | DATA PROCESSING SYSTEM USING CACHE-AWARE MULTIPATH DISTRIBUTION OF STORAGE COMMANDS AMONG CACHING STORAGE CONTROLLERS - A data processing system includes a storage system and caching storage controllers coupled to the storage system and to a storage network. The storage controllers operate in an active-active fashion to provide access to volumes of the storage system from any of the storage controllers in response to storage commands from the storage network. The storage controllers employ a distributed cache protocol in which (a) each volume is divided into successive chunks of contiguous blocks, and (b) either chunk ownership may be dynamically transferred among the storage controllers in response to the storage commands, or storage commands sent to a non-owning controller may be forwarded to the owning controller. A multipathing initiator such as a server computer directs the storage commands to the storage controllers by (1) for each volume, maintaining a persistent association of the chunks of the volume with respective storage controllers, and (2) for each storage request directed to a target chunk, identifying the storage controller associated with the target chunk and sending a corresponding storage command to the identified storage controller. Chunk ownership tends to stabilize at individual storage controllers, reducing unnecessary transfer of cache data and metadata among the storage controllers. | 02-03-2011 |

| 20100050323 | HOCKEY HELMET COMPRISING AN OCCIPITAL ADJUSTMENT MECHANISM - Hockey helmet for receiving a head of a wearer, the helmet comprising: (a) a front shell for facing the crown region of the head; (b) a rear shell for facing the left and right side regions, the back region and the occipital region of the head, the rear shell comprising outer and inner surfaces and left and light elongated slots positioned symmetrically about a longitudinal axis of the helmet; (e) a rear inner pad for facing the back and left and right side regions of the head, the rear inner pad being affixed to the inner surface of the rear shell; (d) an occipital inner pad located between the rear shell and the occipital region of the head; (e) a central member extending along the longitudinal axis of the helmet, the central member comprising an upper part that is hingely mounted with respect to the rear shell and a lower part that is mounted to the occipital inner pad; and (f) left and right wedging members located between the occipital inner pad and the inner surface of the rear shell, each of the left and right wedging members being movable from a first position to a second position wherein, in use, in the second position, the occipital inner pad applies pressure upon the occipital region of the head for urging the front shell towards the crown region of the head. The rear shell of the helmet has a curvature, the occipital inner pad has a rear surface that extends generally perpendicularly about the longitudinal axis of the helmet, each of the left and right wedging members has a front portion contacting the rear surface of the occipital inner pad and movement of each of the left and right wedging members away from the longitudinal axis follows the curvature of the rear shell such that the occipital inner pad moves towards the second position. | 03-04-2010 |

| 20090188022 | HOCKEY HELMET WITH AN OUTER SHELL MADE OF TWO DIFFERENT MATERIALS - The present invention covers a hockey helmet for receiving a head of a player. The helmet comprises an outer shell made of first and second materials having respective first and second flexibilities. The outer shell comprises a front portion for at least partially facing the crown region of the head, a top portion for at least partially facing the top region of the head, a back portion for at least partially facing the back region of the head, an occipital portion for at least partially facing the occipital region of the head, and left and right portions for at least partially facing the left and right side regions of the head, the left and right portions comprising respective left and right projections that extend downwardly in front of the respective left and right ears and left and right sections located above and behind the respective left and right ears wherein one of the occipital portion, left and right projections and left and right sections is made of the second material and wherein the second flexibility is greater from the first flexibility. | 07-30-2009 |

| 20080315611 | VIBRATION DAMPENER FOR SUPPORT BRACES IN VEHICLES - A support brace supports the instrument panel above the floor pan of an automotive chassis and includes a lap joint that dampens the transmission of low range vibrations through the support brace to the instrument panel. The support brace is formed in two pieces, an upper member and a lower member, that have an overlap section between them. The overlap sections are joined to an elastomeric pad to form the re-configured support brace. The elastomeric pad can be bonded to the overlap sections or joined with rubber buttons inserted through holes formed in the overlap sections. The overlap sections are vertically spaced above the floor pan to position the elastomeric pad above the heat generated by the vehicle exhaust system. The elastomeric pad can be formed in segments with vertically oriented spaces between the individual segments. | 12-25-2008 |
| 20110095570 | Vibration Dampener with Floating Positive Mechanical Connection - A support brace supports the instrument panel above the floor pan of an automotive chassis and includes a lap joint that dampens the transmission of low range vibrations through the support brace to the instrument panel. The support brace is formed in two pieces, an upper member and a lower member, that have an overlap section between them, where an elastomeric pad joins the two members. The elastomeric pad can be bonded to the overlap sections or joined with rubber buttons inserted through holes formed in the overlap sections. The overlap sections are vertically spaced above the floor pan to position the elastomeric pad above the heat generated by the vehicle exhaust system. A floating positive mechanical connection in the form of an interlocking tab on one member engaged through an opening in the other member, which stays out of metal to metal contact unless the elastomeric pad fails. | 04-28-2011 |

| 20090048158 | Insulin-Like Growth Factor Binding Protein-4 Compounds and Methods for Inhibiting Angiogenesis and Tumor Growth in Mammalian Cells - The use of fragments of IGFBP-4 for inhibiting angiogenesis and tumor growth is described. | 02-19-2009 |
| 20100261275 | Production of Recombinant Interferon Proteins - A method of purifying a recombinant interferon protein involves providing an aqueous mixture of the recombinant protein and contaminating proteins; precipitating the contaminating proteins from the aqueous mixture at a pH in a range of from 0.5 to 6; separating the aqueous mixture from the precipitated contaminating proteins; and, eluting the separated aqueous mixture through a cation exchange column using a mobile phase with a salt or pH gradient, the gradient being from lower salt concentration or pH to higher salt concentration or pH, to produce a recombinant interferon protein fraction separated from other components of the aqueous mixture. The method provides for the recovery of recombinant interferon proteins in better yield and purity. | 10-14-2010 |
| 20110039339 | Process, Vectors and Engineered Cell Lines for Enhanced Large-Scale Transfection - Processes vectors and engineered cell lines for large-scale transfection and protein production in mammalian cells, especially Chinese Hamster Ovary (CHO) cells are described in which transfection efficiencies are realized through the use of a single vector system, the use of functional oriP sequences in all plasmids, the use of codon-optimized Epstein-Barr virus nuclear antigen-1 (EBNA1) constructs the use of a fusion protein between a truncated Epstein-Barr virus nuclear antigenen-1c (EBNA1c) protein and a herpes simplex virus protein VP16, the use of a 40 kDa fully deacetylated poly(ethylenimine) as a transfection reagent, the use of co-expression of a fibroblast growth factor (FGF) and/or the use of protein kinase B to potentiate heterologous gene expression enhancement by valproic acid (VPA). | 02-17-2011 |
