| 20080308684 | NACELLE WITH ARTICULATING LEADING EDGE SLATES - A nacelle includes leading edge slates movable to modify inlet shape and area airflow into the nacelle. The articulating leading edge slats are movable for tailoring incoming airflow to current aircraft operating conditions. An actuator disposed within a thickness of the nacelle drives leading edge slates to a desired position to vary the inlet area and shape. | 12-18-2008 |
| 20090003997 | VARIABLE SHAPE INLET SECTION FOR A NACELLE ASSEMBLY OF A GAS TURBINE ENGINE - A nacelle assembly includes an inlet section having a plurality of discrete sections. Each of the plurality of discrete sections includes an adaptive structure. A thickness of each of the plurality of discrete sections is selectively adjustable between a first position and a second position to influence the adaptive structure of each of the plurality of discrete sections. | 01-01-2009 |
| 20090123274 | SPLIT GEARBOX AND NACELLE ARRANGEMENT - A gas turbine engine is disclosed that includes at least first and second gearboxes rotationally coupled to at least one spool. Accessory drive components are mounted on and driven by the gearboxes. The accessory drive components include, for example, a fuel pump, a hydraulic pump, a generator, a lubrication pump, or a starter. The accessory drive components are split between the two gearboxes to reduce the diameter of the nacelle adjacent to each gearbox. | 05-14-2009 |
| 20090146331 | DEFORMABLE MOLDS AND METHODS FOR THEIR USE IN THE MANUFACTURE OF OPHTHALMIC LENSES - The present provides deformable molds and methods for manufacturing ophthalmic lenses using deformable molds. The molds of the invention may be used in the custom manufacture of ophthalmic lenses. | 06-11-2009 |
| 20100161244 | METHOD AND APPARATUS FOR MONITORING STRUCTURAL HEALTH - A method includes performing a first damage prediction with a computational model using at least data from a first multitude of damage sensors on a structure, performing a second damage prediction with the computational model using at least data from a second multitude of load sensors associated with the structure, and selectively performing a damage monitoring action in response to the first damage prediction and the second damage prediction to determine a structural health A system includes a computing device configured to perform a first damage prediction using at least data from a multitude of damage sensors on a structure, a second damage predication using at least data from a multitude of load sensors associated with the structure, so as to selectively perform a damage monitoring action in response to the first damage prediction and the second damage prediction to determine a structural health of the structure. | 06-24-2010 |
| 20100262300 | ACTIVE VIBRATION SUPPRESSION VIA POWER MINIMIZATION - A vibration suppressor system includes a control system operable to control power from a power system to an actuator system in response to a minimal actuation power algorithm. The minimal actuation power algorithm employs a real electric power consumption of the actuator system as a single control objective function to suppress a vibration of the structure. | 10-14-2010 |
| 20110209507 | SEMI-ACTIVE ELECTRORHEOLOGICAL FLUID CLUTCH FOR ELECTRONIC DOOR LOCK - A clutch for an electronic door lock includes a first shaft, a second shaft, a spring, a rheological fluid, and a plunger. The second shaft has an aperture therein and is axially co-aligned with the first shaft and is rotatably mounted adjacent the rotatable first shaft. The spring is disposed in the aperture in the second shaft. The rheological fluid is held within the aperture and is capable of changing viscosities in response to the application of an electrical current across the fluid. The plunger is biased by the spring into selective coupling engagement with the first shaft and is capable of selective motion into the aperture in response to contact by a camming surface of the first shaft due to relative rotation of the first shaft with respect to the second shaft. | 09-01-2011 |
| 20110210564 | BI-STABLE ACTUATOR FOR ELECTRONIC LOCK - An actuator for an electronic door lock includes a stationary first magnet assembly, a beam, and a second magnet assembly. The first magnet includes at least one magnet stationarily positioned within the electronic door lock. The beam is movable relative to the first magnet assembly to a first position and a second position. The second magnet assembly is connected to the beam and is configured to be magnetically repulsed away from the first magnet assembly. The repulsion of the second magnet assembly maintains the beam in either the first or second position until the beam is selectively actuated therefrom. | 09-01-2011 |
