| 20110035555 | METHOD AND APPARATUS FOR AFFINITY-GUIDED SPECULATIVE HELPER THREADS IN CHIP MULTIPROCESSORS - Apparatus, system and methods are provided for performing speculative data prefetching in a chip multiprocessor (CMP). Data is prefetched by a helper thread that runs on one core of the CMP while a main program runs concurrently on another core of the CMP. Data prefetched by the helper thread is provided to the helper core. For one embodiment, the data prefetched by the helper thread is pushed to the main core. It may or may not be provided to the helper core as well. A push of prefetched data to the main core may occur during a broadcast of the data to all cores of an affinity group. For at least one other embodiment, the data prefetched by a helper thread is provided, upon request from the main core, to the main core from the helper core's local cache. | 02-10-2011 |

| 20110145501 | CACHE SPILL MANAGEMENT TECHNIQUES - An apparatus and method is described herein for intelligently spilling cache lines. Usefulness of cache lines previously spilled from a source cache is learned, such that later evictions of useful cache lines from a source cache are intelligently selected for spill. Furthermore, another learning mechanism—cache spill prediction—may be implemented separately or in conjunction with usefulness prediction. The cache spill prediction is capable of learning the effectiveness of remote caches at holding spilled cache lines for the source cache. As a result, cache lines are capable of being intelligently selected for spill and intelligently distributed among remote caches based on the effectiveness of each remote cache in holding spilled cache lines for the source cache. | 06-16-2011 |

| 20090046130 | Electrostatic Actuator And Fabrication Method - In one embodiment a method of making an electrostatic actuator includes: forming a first conductor over a first substrate to form a first structure; forming a flexible second conductor over a second substrate to form a second structure; forming an etch stop over the first conductor as part of the first structure or over the second conductor as part of the second structure; forming a spacer on the etch stop, the spacer selectively etchable with respect to the etch stop; etching the spacer through to the etch stop at a location of a gap between the first conductor and the second conductor; and bonding the first structure and the second structure together such that the first conductor is located opposite the second conductor across the gap. | 02-19-2009 |

| 20100287715 | Fenders for Pier Protection Against Vessel Collision - A system is disclosed for protecting supporting structures, such as those of a bridge or other such marine supporting structure, from the force of an impact of a vehicle/vessel. Such a system includes a plurality of modular components arranged in series and configured to dissipate the energy of the force through the progressive buckling of one or more of the modular components. Each modular component contains an energy dissipation unit that includes a plurality of adjacent cells. The energy of the force is dissipated in the buckling of the walls of the cells of the energy dissipation units through the formation of one or more plastic hinges and/or volume reduction of the cells. | 11-18-2010 |
