20090212159 | Restraint System - In a preferred embodiment, a restraint system is described for restraining a standing occupant in a vehicle such as a plane or helicopter. The restraint system includes a webbing strap that winds and unwinds from a spool assembly. The spool assembly includes a trigger assembly that locks a spool from rotation, a manual release assembly for manually releasing the trigger assembly and lock, and an adjustable payout assembly that determines the maximum length that the webbing strap can be pulled out before stopping (i.e., the number of rotations of the spool). The trigger assembly can trigger the lock assembly from one or more sensors. Further, the trigger assembly can be arranged to automatically unlock after a triggering event, manually unlocked after a triggering event or a combination of the two for different sensors. | 08-27-2009 |

20100011702 | OPAQUE FIBER REINFORCEMENT OF COMPOSITES - A composite material includes a polymeric matrix, at least one transparent region including a plurality of optically clear elements provided in the polymeric matrix and at least one opaque region including a plurality of opaque reinforcing elements provided in the polymeric matrix generally adjacent to the at least one transparent region. A structural window and a method for reinforcing a composite material are also disclosed. | 01-21-2010 |
20100075090 | VARIED GLASS DENSITY REINFORCEMENT OF COMPOSITES - A transparent reinforced composite material. An illustrative embodiment of the reinforced composite material includes a polymeric matrix, at least one low-density region including a first plurality of glass elements having a first packing density provided in the polymeric matrix and at least one high-density region including a second plurality of glass elements having a second packing density greater than the first packing density provided in the polymeric matrix. A method for reinforcing a composite material is also disclosed. | 03-25-2010 |
20100316859 | Varied Glass Density Reinforcement of Composites - A transparent reinforced composite material. An illustrative embodiment of the reinforced composite material includes a polymeric matrix, at least one low-density region including a first plurality of glass elements having a first packing density provided in the polymeric matrix and at least one high-density region including a second plurality of glass elements having a second packing density greater than the first packing density provided in the polymeric matrix. A method for reinforcing a composite material is also disclosed. | 12-16-2010 |
20110230596 | GLASS FIBERS HAVING IMPROVED STRENGTH - A glass fiber and a method of manufacturing a glass fiber for reinforcing a transparent composite matrix are disclosed. The glass fiber includes a first glass material having a first set of mechanical properties including a first modulus and a first coefficient of thermal expansion (CTE) and a second glass material having a second set of mechanical properties including a second modulus and a second CTE. The second glass material forms a substantially uniform coating on the first glass material. The second CTE is less than the first CTE. The glass fiber is formed by reducing the cross-section of a glass fiber preform of the first glass material coated with the second glass material by hot working. Because of the selected difference in the CTE's, the first glass material imparts a compressive force upon the second glass material, which improves the strength of the glass fiber. | 09-22-2011 |
20110230597 | GLASS FIBERS HAVING IMPROVED DURABILITY - A glass fiber and a method of manufacturing a glass fiber for reinforcing a transparent composite matrix is disclosed. The glass fiber includes a first glass material having a first refractive index, a first modulus, and a first durability characteristic and a second glass material having a second refractive index, a second modulus, and second durability characteristic. The second durability characteristic is greater than the first durability characteristic. Durability characteristic is selected from the group comprising resistance to chemical attack, resistance to acid attack, resistance to fading from exposure to ultra-violet radiation, and resistance to mechanical abrasion. | 09-22-2011 |
