In accordance with this invention, an apparatus and method for aircraft navigation are provided that utilize a blended architecture consisting of a global positioning system (GPS) and micro-electromechanical sensors (MEMS) for the primary navigation system and a laser gyroscope system for the second
In accordance with this invention, an apparatus and method for aircraft navigation are provided that utilize a blended architecture consisting of a global positioning system (GPS) and micro-electromechanical sensors (MEMS) for the primary navigation system and a laser gyroscope system for the secondary navigation system. The blended architecture of the present invention provides a navigation system that is at least as accurate, redundant and fault-tolerant as conventional navigation systems. In addition, the navigation system components may be distributed throughout the aircraft and may share computing resources with other avionics systems to process signals and provide data to the avionics systems. Overall, the navigation system of the present invention is significantly less expensive and easier to maintain, but equally or more precise and redundant, relative to conventional navigation systems.

A developer container according to claim 1, further comprising a groove into which said liquid elastomer is supplied, wherein said groove is larger at the start point and at the end point than in the intermediate portion. 3. A developer container according to claim 2, wherein a volume of said groove is larger at the start point and the end point than a volume in the intermediate portion, in a direction of a height of said groove. 4. A developer container according to claim 2, wherein a volume of said groove is larger at the start point and the end point than a volume in the intermediate portion, in a widthwise direction perpendicular to a longitudinal direction in which said liquid elastomer is supplied. 5. A developer container according to claim 2, wherein said groove comprises an inclined surface along which a size of an opening increases from a back side at which said liquid elastomer is injected toward a front side. 6. A developer container according to claim 5, wherein said inclined surface is formed along a longitudinal direction in which said liquid elastomer is supplied. 7. A developer container according to claim 5, wherein said plurality of members include a container body and a blade supported by said container body, wherein said groove is formed in a space defined by said container body and said blade, and wherein said inclined surface is formed in said container body. 8. A developer container according to claim 5, wherein said liquid elastomer is guided to a back side along said inclined surface. 9. A developer container according to claim 2, wherein said plurality of members include a container body and a blade supported by said container body, and wherein said groove is formed in a space defined by said container body and said blade. 10. A developer container according to claim 2, wherein said groove is formed in a direction perpendicular to a direction in which said liquid elastomer is injected, and includes at least one of a hole, recess, and projection into which said liquid elastomer is inserted. 11. A developer container according to claim 10, wherein said at least one of hole, recess, and projection are formed between said plurality of members. 12. A developer container according to claim 11, wherein a through hole extending to an outside of said developer container is formed in said at least one hole and recess. 13. A developer container according to claim 10, wherein a through hole extending to a outside of said developer container is formed between said plurality of members. 14. A developer container according to claim 10, wherein a length along which said liquid elastomer is supplied is larger than a length of at least one of said plurality of members. 15. A developer container according to claim 1, wherein said plurality of members include a container body and a blade supported by said container body. 16. A developer container according to any one of claims 1 to 4 and 5 to 14, wherein said developer container is formed in a cartridge, which can be installed in and removed from a main body of an image forming apparatus. 17. A developer container according to claim 16, wherein the cartridge includes an image carrier for carrying an image. 18. A developer container containing, comprising: a developer containing unit containing a developer; a sealing member supplied between a container body and a blade to prevent leakage of the developer, said sealing member being a liquid elastomer; and at least one of a hole, recess, and projection, which is formed in a direction perpendicular to a direction in which said liquid elastomer is injected, and into which said liquid elastomer is inserted. 19. A developer container according to claim 18, wherein said at least one of hole, recess, and projection are formed between said plural
