| 20110062210 | TWO-STAGE, FLAT CLINCHING STAPLER - A stapler comprises a mechanism to first fully drive staples into sheets of materials, e.g., paper, and only then to fold over the legs of the staples. This results in a flat clinch and very few crumpled staples. An anvil table is locked in a raised position above a staple anvil, and a trigger mechanism will operate only when a staple blade has proceeded through a staple magazine and forced a staple fully out. The trigger mechanism slides back when this happens, and unlocks the anvil table so it can drop down around a staple-leg-folding anvil. The whole top of the stapler and the papers being stapled drop with the already fully inserted staple onto the anvil to fold the staple legs over flat. | 03-17-2011 |

| 20080259506 | ESD, cross talk and noise pickup minimizing scheme for CPP and TMR devices - A slider mounted CPP GMR or TMR read head sensor is protected from electrostatic discharge (ESD) damage and from noise and cross-talk from an adjacent write head by means of a balanced resistive/capacitative shunt. The shunt includes highly resistive interconnections between upper and lower shields of the read head and a grounded slider substrate and a low resistance interconnection between the lower pole piece of the write head and the substrate. The capacitances between the pole piece and the upper shield, the upper shield and the lower shield and the lower shield and the substrate are made equal by either forming the shields and pole piece with equal surface areas and separating them with dielectrics of equal thicknesses, or by keeping the ratio of area to insulator thicknesses equal. | 10-23-2008 |

| 20080227957 | Reducing Immunogenicities of Immunoglobulins by Framework-Patching - Framework (FR)-patching is a novel approach to modify immunoglobulin for reducing potential immunogenicity without significant alterations in specificity and affinity. Unlike previous described methods of humanization, which graft CDRs from a donor onto the frameworks of a single acceptor immunoglobulin, we patch segments of framework (FR1, FR2, FR3, and FR4), or FRs, to replace the corresponding FRs of the parent immunoglobulin. Free assortment of these FRs from different immunoglobulins and from different species can be mixed and matched into forming the final immunoglobulin chain. A set of criteria in the choice of these FRs to minimize or eliminate the need to reintroduce framework amino acids from the parent immunoglobulin for patching is described. The approach gives greater flexibility in the choice of framework sequences, minimizes the need to include parent framework amino acids, and, most importantly, reduces the chances of creating new T- and B-cell epitopes in the resultant immunoglobulin. | 09-18-2008 |

| 20080205088 | Multi-input DC/DC converters with zero-current switching - A modular-based, zero-current-switched (ZCS), isolated full-bridge boost converter with multiple inputs is disclosed. Each converter module is used to match the connected input source and control the amount of power drawn from the source. The power from various sources are combined together and delivered to the load through a multiphase transformer. The input inductor of each boost-derived converter module keeps the input current constant and acts as a current source to drive the multiphase transformer through a phase-shifted-controlled full bridge converter. By connecting an auxiliary circuit across the full-bridge input in each module, the transformer leakage inductance and output capacitance of the switching devices are used to create resonant paths for facilitating zero-current-switching of all switching devices. | 08-28-2008 |
