20110056401 | METHODS AND APPARATUSES FOR ELECTRO-MECHANICAL SAFETY AND ARMING OF A PROJECTILE - A safety and arming apparatus for use with a projectile includes a rotor pivotable between a safe position and an armed position. A biasing element holds a mass engaged with the rotor to restrain the rotor from rotation and is deformable to allow the mass to displace and disengage from the rotor in response to a setback force on the projectile. A second biasing element includes a displaceable end for engaging with the rotor to restrain the rotor from rotation and is deformable to disengage the displaceable end from the rotor in response to projectile spin. A piston actuator can rotate the rotor to the armed position if the mass is disengaged and the displaceable end is disengaged. A detonator on the rotor can be aligned with a detonation cord when the rotor is in the armed position and unaligned when the rotor is in the safe position. | 03-10-2011 |

20140029635 | LASER POWER CONTROL USING BIAS AND MODULATION CURRENT FEEDBACK - Techniques are described for maintaining the extinction ratio of an output optical signal over temperature and aging. In some examples, the techniques may determine the instantaneous slope efficiency of the laser outputting the optical signal, while the laser is outputting the optical signal. Based on the determined slope efficiency, the techniques may determine the needed drive current components (e.g., at least one of the bias current and the modulation current) that results in maintaining the extinction ratio to within a desired range. | 01-30-2014 |

20090294926 | DEEP TRENCH IN A SEMICONDUCTOR STRUCTURE - A semiconductor structure. A hard mask layer is on a top substrate surface of a semiconductor substrate. The hard mask layer includes a hard mask layer opening through which a portion of the top substrate surface is exposed to a surrounding ambient. The hard mask layer includes a pad oxide layer on the top substrate surface, a nitride layer on the pad oxide layer, a BSG (borosilicate glass) layer on top of the nitride layer, and an ARC (anti-reflective coating) layer on top of the BSG layer. A BSG side wall surface of the BSG layer is exposed to the surrounding ambient through the hard mask layer opening. | 12-03-2009 |

20150273252 | FIREFIGHTING OR RESCUE APPARATUS INCLUDING A LADDER MOUNTED RECOVERY WINCH - A firefighting or rescue apparatus includes a ladder to which a recovery winch is operably mounted so that the winch can be used to move, upright, lift or otherwise manipulate target objects at an emergency location. The ladder can include a pulley detachably mounted to the ladder distal from the winch, the pulley adapted to suspend a cable extending from the winch at an upper end. In operation, the winch moves along with the ladder as the ladder moves, so that the winch and pulley can be strategically located over a target object for movement thereof. The apparatus can include a remote control connected to the winch for operation of the winch by a user. | 10-01-2015 |
20150273255 | FIREFIGHTING OR RESCUE APPARATUS INCLUDING LADDER WITH STATUS INDICATORS - A firefighting or rescue apparatus includes an aerial ladder and at least one of a rung alignment status indicator and a load status indicator. The rung alignment status indicator can include a lighting strip having multiple lighting elements on the ladder that are selectively illuminated depending on whether first rungs of one section of the ladder and second rungs of another section of the ladder are aligned or misaligned. A user on the aerial ladder can view the rung alignment status indicator and discern whether the ladder has appropriate rung alignment so the user can attain a safe foothold when climbing it. The load status indicator can include a lighting strip including multiple lighting elements on the ladder and/or at a control console that are selectively illuminated depending on whether the ladder is overloaded beyond an aerial ladder capacity rating or other value. A user on the aerial ladder and/or at a control console can view the load status indicator to discern whether the ladder is improperly overloaded to a point where the apparatus might tip or overturn. | 10-01-2015 |

20100114137 | SURGICAL INSTRUMENT HAVING AN ARTICULATED JAW STRUCTURE AND A DETACHABLE KNIFE - A surgical instrument with articulated jaw structure includes a frame and two jaws. The jaws have proximal portions that are mounted to each other for movement in a substantially parallel relation between a fully open position wherein the jaws are separated for receiving tissue therebetween and an approximated position wherein the jaws are closer together. Preferably, the jaws are in the fully open position when the distal portion of at least of the jaws is located in an extended position and are in the approximated position when the distal portion of the extended jaw or jaws is located in a retracted position. The surgical instrument may further include a detachable knife assembly and knife actuating mechanism. | 05-06-2010 |
