| 20080320249 | FULLY BUFFERED DIMM READ DATA SUBSTITUTION FOR WRITE ACKNOWLEDGEMENT - A memory controller uses a scheme to retire two entries from a replay queue due to a single non-error response. Advantageously, entries in a replay queue may be retired earlier than conventional systems, minimizing the size of the replay queue. | 12-25-2008 |
| 20090327596 | MEMORY CONTROLLER USING TIME-STAGGERED LOCKSTEP SUB-CHANNELS WITH BUFFERED MEMORY - Memory control techniques for dual channel lockstep configurations are disclosed. In accordance with one example embodiment, a memory controller issues two burst-length 4 DRAM commands to two double-data-rate (DDR) DRAM sub-channels behind a memory buffer (e.g., FB-DIMM or buffer-on-board). The two commands are in time-staggered lockstep. The time-stagger allows data coming back from the two back-side DDR sub-channels to flow naturally on the host channel without conflict. Multiple DIMMs can be used to obtain chip-fail ECC capabilities and to reclaim at least some of the lost performance imposed by the burst-length of 4 s typically associated with dual channel lockstep memory controllers. The techniques can be implemented, for instance, with a buffered memory solution such as fully buffered DIMM (FB-DIMM) or buffer-on-board configurations. | 12-31-2009 |

| 20090000421 | COMPRESSED HUB DAMPER - A torsional vibration damper includes front and rear hub members with an inertia mass between the two hub members. Annular elastomeric rings are positioned between the front and rear hub members and the inertia mass holding the inertia mass. Fasteners extend through the front hub member, the inertia mass, and fixed to the rear hub member. A clearance between the fastener and the inertia mass allows relative motion to absorb torsional vibration. | 01-01-2009 |
| 20090000422 | RECESSED BELT DAMPER - A torsional vibration damper includes an inertia mass and a rotating shaft or hub with an elastomeric ring between the inertia mass and the rotating shaft or hub. A large portion of said elastomeric member is located in a channel located either in the inertia mass or in the hub. This allows one to achieve high contact pressure without creating a significant fatigue on the elastomeric member. This can be used with either a crankshaft damper or an internal or external drive shaft damper. | 01-01-2009 |
| 20090078079 | DECOUPLED VIBRATION DAMPER - A torsional vibration damper includes a one-piece integral hub and annular inertia mass assembly. Between the hub and the inertia mass are intermediate rings connected integrally with the mass and the hub connected integral spokes. Elastomeric members are compression fitted within spaces formed between the hub and the mass. With this design, the damper can be formed from a polymeric material with an embedded annular weight. | 03-26-2009 |

| 20110250936 | SYSTEM AND METHOD FOR PROVIDING A PERFORMANCE FACTOR FOR A PITCHER - The present invention provides a visual representation of and unique, universal definition for a strike zone, said strike zone having a plurality of sub-zones. The strike zone representation allows for a signaling methodology to be developed in which a coach may discretely communicate signals during a game to his pitcher (ex.—baseball or softball pitcher) which request both a specific type and location for a particular pitch, based upon the game situation. Further, implementation of said signaling methodology based upon said strike zone representation allows for a performance factor to be determined for the pitcher. The performance factor may be determined based on results generated through use of the signaling methodology and may provide a universally-recognized gauge or measure of a pitcher's command of his pitches. | 10-13-2011 |

| 20090134169 | MULTI SECTIONAL BUCKET - A bucket having three or more sections for separating wash liquid. Dividers create the sections and are placed in an up position when filling the bucket so that the water will flow throughout the entire bucket. The dividers can then slide back down to create the separated sections of clean liquid. The dividers can be connected to each other by means of horizontal bars attached on the top of the dividers which run along the sides of the bucket along the inside. Lifting the horizontal bar up will lift all of the attached dividers up simultaneously. The horizontal bars can be provided in two sections that can be connected to each other. When the two sections are disconnected, when one lifts one bar section, only the attached dividers will lift up simultaneously, while the other bar section and its attached divider will remain in its down position. | 05-28-2009 |

| 20080248604 | Post-logic isolation of silicon regions for an integrated sensor - In producing an integrated sensor, regions of silicon between compensating electronics and a sensor are electrically isolated, while the sensor is delineating and released. The described process can be performed at the end of a fabrication process after electronics processing (i.e., CMOS processing) and compensating electronics are formed. In an aspect, the sensor and a conductive bridge are simultaneously developed from a silicon-on-insulator (SOI) substrate. In an aspect, the sensor is undercut from a silicon substrate utilizing a lateral etch. A cavity is concurrently defined by the same lateral etch in the silicon layer, forming the conductive bridge connecting the sensor to a logic component. An isolation trench is defined in the silicon layer between the sensor components and the logic component. A polymer masks vertical surfaces from the lateral etch, and an insulator layer and photosensitive film mask horizontal surfaces from the lateral etch. | 10-09-2008 |

| 20090237188 | Integrated Reed Switch - This invention relates to reed switches, and more particularly to micro-miniaturized reed switches and batch microfabrication techniques used to fabricate micro-miniaturized reed switches. The present invention can provide miniaturized reed switches with more consistent operating parameters, and that can be produced more efficiently than conventional reed switches. The present invention can also provide methods of making miniaturized reed switches using microfabrication techniques. The present invention can use lithographic-based fabrication to enable monolithic construction of a reed switch. Microlithography can repeatedly form micrometer dimensions with tight tolerances over large arrays of devices which, if the patterns are translated into materials appropriate for electromechanical devices, can provide for repeatable and consistent electromechanical operation. For example, tight dimensional control of the gap between two reeds in a reed switch or a reed and a fixed contact can provide consistency of performance between reed switches. Thus, the present invention can allow the commonly regarded reed switch specification of sensitivity, or “Ampere-turns” required to close a reed switch, to be tightly controlled with a commensurate reduction in spread in sensitivity across reed switch production lots. | 09-24-2009 |
