| 20120031010 | POTTED PANEL LATCH SYSTEM - A method of preparing and a finished panel and latch combination, wherein the panel and latch mounting combination are seamless and attractive. | 02-09-2012 |
| 20110101712 | DAMPENED BAYONET LATCH - A latch mechanism is described allowing controlled access to the area secured by the latch mechanism, wherein the latch element is captured and released by the latch mechanism only upon slow, steady pressure overriding a dampening element. Sudden movement of the latch element is resisted in relationship to the force applied. | 05-05-2011 |
| 20100102170 | ENERGY ABSORBING SEAT - A lightweight airplane seat using composite material to form a four-bar linkage, pivotal at the corners to reduce torque stresses and including a frangible compressible strut to absorb the forces generated during a crash. | 04-29-2010 |
| 20100040828 | Latch cover - A lightweight, strong article of manufacture wherein the surfaces are fabricated of an adhesive-impregnated fiber fabric having the desired properties; and where additional stiffness is required, a honeycomb material is sandwiched between the surfaces, greatly increasing the rigidity with only a slight increase in weight. | 02-18-2010 |
| 20090152878 | RESETTABLE RELEASE LATCH - A resettable securement latch for a panel which allows release of the panel upon a predetermined pressure across the panel and includes means incorporating a frangible element which can be quickly restored to resecure the panel to its original position and condition. | 06-18-2009 |
| 20090152397 | SELECTIVE RELEASE LATCH - A selectively released latch securing a panel in position, but which resists release in response to sudden movement of the panel, yet allowing release in response to a slow and steady movement of the panel. | 06-18-2009 |
