| 20090320027 | FENCE ELISION FOR WORK STEALING - Methods and systems for statistically eliding fences in a work stealing algorithm are disclosed. A data structure comprising a head pointer, tail pointer, barrier pointer and an advertising flag allows for dynamic load-balancing across processing resources in computer applications. | 12-24-2009 |
| 20100131720 | MANAGEMENT OF OWNERSHIP CONTROL AND DATA MOVEMENT IN SHARED-MEMORY SYSTEMS - A method to exchange data in a shared memory system includes the use of a buffer in communication with a producer processor and a consumer processor. The cache data is temporarily stored in the buffer. The method includes for the consumer and the producer to indicate intent to acquire ownership of the buffer. In response to the indication of intent, the producer, consumer, buffer are prepared for the access. If the consumer intends to acquire the buffer, the producer places the cache data into the buffer. If the producer intends to acquire the buffer, the consumer removes the cache data from the buffer. The access to the buffer, however, is delayed until the producer, consumer, and the buffer are prepared. | 05-27-2010 |

| 20110213025 | Catheter Lock Solutions Utilizing Tocopherol and Mid-Chain Fatty Acids - Methods, compositions and kits are disclosed for infusing a hydrophobic catheter lock solution into an indwelling catheter. The combination of a tocopherol compound and at least one saturated mid-chain fatty acid provides a broad spectrum antimicrobial solution with optimal viscosity for effectively locking a catheter. The lock can effectively reduce or eliminate the risk of infection and prevents tainting the catheter, particularly clotting and thrombus in intravascular and extravascular catheters. The potential for this discovery is for maintaining or reestablishing the viability of an intravascular or extravascular catheter, as well as topical formulations for promoting healing. | 09-01-2011 |

| 20100173512 | High power, single pole electrical connector - A high-power, single-pole electrical connector is disclosed. A nonconductive mounting base is used to attach the connector to an electrical distribution panel. The connector extending from the panel has a bolted together connection that is safe and secure. Other connectors of this type use a pin-and-collet configuration. The bolted together connection of the present invention may provide additional security over a pin-and-collet design. | 07-08-2010 |

| 20110085881 | Track hoe attachment to load and unload pipe - A track hoe bucket attachment for purposes of loading and unloading pipe comprising two tines connected at one end by a pipe. The pipe has an opening that is capable of receiving the teeth of the track hoe bucket. The two tines are further connected by a support bar which has eyelets at its two ends. The eyelets of the support bar receive a chain that is connected to the track hoe to further secure the attachment to the track hoe. | 04-14-2011 |

| 20110144272 | COMPOSITIONS USEFUL FOR PREPARING COMPOSITES AND COMPOSITES PRODUCED THEREWITH - A composite prepared using a thermosettable epoxy resin composition having, as components: (1) an epoxy resin; (2) an epoxidized cycloaliphatic dicyclopentadiene phenolic resin; (3) an optional epoxidized bisphenol-A novolac resin; (4) an optional oligomeric butadiene; (5) an optional organic solvent; and (6) an alkylphenol novolac resin, the alkylphenol novolac resin serving as a curing agent. The composite so prepared may have good physical properties and superior a electrical properties as compared to conventional composites, such as laminates. The prepregs used to make the laminates may have a better surface appearance as well. | 06-16-2011 |
