| 20090268512 | MRAM with cross-tie magnetization configuration - The incidence of half-select errors during MRAM programming has been significantly reduced by giving the free layer a shape that approximates an X so that, when the free layer switches, the magnetization in the arms of the X guides the magnetization in the central section (the X's intersection area) causing it to rotate towards the hard axis in two opposing directions. This raises the free layer's switching energy barrier, thereby reducing half-select errors. | 10-29-2009 |

| 20110062536 | Design and fabrication methods of partial cladded write line to enhance write margin for magnetic random access memory - A cladding structure for a conductive line used to switch a free layer in a MTJ is disclosed and includes two cladding sidewalls on two sides of the conductive line, a top cladding portion on a side of the conductive line facing away from the MTJ, and a highly conductive, non-magnetic spacing control layer formed between the MTJ and conductive line. The spacing control layer has a thickness of 0.02 to 0.12 microns to maintain the distance separating free layer and conductive line between 0.03 and 0.15 microns. The spacing control layer is aligned parallel to the conductive line and contacts a plurality of MTJ elements in a row of MRAM cells. Half-select error problems are avoided while maintaining high write efficiency. A spacing control layer may be formed between a word line and a bottom electrode in a top pinned layer or dual pinned layer configuration. | 03-17-2011 |

| 20090096982 | Interchangeable Charm System for Glasses - Glasses for receiving interchangeable charms are disclosed. The glasses are adaptable for releasably and interchangeably attaching and securing a variety of charms such that the plane of the backside of the charm is flush against a convex or smooth outwardly facing surface on a pair of glasses. In a preferred embodiment, the glasses in the present invention comprise a depressed region further comprising a planar magnetic base surrounded on all sides by walls substantially perpendicular thereto. Each charm in the present invention has a second magnet adapted for tight fitment into said depressed region, so as to be held in place by magnetic attraction when brought into close proximity with said depressed region. | 04-16-2009 |

| 20090174293 | HIGH-PERFORMANCE ELECTROACTIVE POLYMER TRANSDUCERS - Electroactive polymer constructions that convert electrical energy to mechanical energy and vice versa are disclosed. The subject transducers (actuators, generators, sensors or combinations thereof) share the requirement of a frame or fixture element used in preloading elastomeric film electrodes and dielectric polymer in a desired configuration. The structures are either integrally biased in a push-pull arrangement or preloaded/biased by another element. | 07-09-2009 |

| 20080252176 | ELECTROACTIVE POLYMER TORSIONAL DEVICE - The present invention relates to mechanical-electrical power conversion systems. The systems comprise one or more electroactive polymers that convert between electrical and mechanical energy. When a voltage is applied to electrodes contacting an electroactive polymer, the polymer deflects. This deflection may be converted into rotation of a power shaft included in a motor. Repeated deflection of the polymer may then produce continuous rotation of the power shaft. | 10-16-2008 |
| 20090241894 | COMPLIANT WALLED COMBUSTION DEVICES - Combustion devices described herein comprise a compliant combustion chamber wall or segment. The compliant segment deforms during combustion in the combustion chamber. Some devices may include a compliant wall configured to stretch responsive to pressure generated by combustion of a fuel in the combustion chamber. A coupling portion translates deformation of the compliant segment or wall into mechanical output. One or more ports are configured to inlet an oxygen source and fuel into the combustion chamber and to outlet exhaust gases from the combustion chamber. | 10-01-2009 |

| 20090295799 | Optimized Frustum Clipping Via Cached Clip Vertices - Apparatus, systems and methods for optimized frustum clipping via cached clip vertices are disclosed. For example, a method is disclosed, the method including generating a clip vertex for a leading edge of a triangle of a triangle strip or fan, indicating that the leading edge is shared with an adjacent triangle of the triangle strip or fan, and in response to the indication, using the clip vertex as a clip vertex of a trailing edge of the adjacent triangle in the triangle strip or fan. Other implementations are disclosed. | 12-03-2009 |
