Abstract: A fiber optic connector assembly comprising: a fiber optic connector (110) and a fiber optic adapter (120). The fiber optic connector comprises a ferrule assembly (110) and is simplified to not comprise a case and/or an insertion body of a standard fiber optic connector disposed outside the ferrule assembly. The fiber optic adapter comprises a simplified port (121) adapted to receive the ferrule assembly (110) therein and an elastic piece (130) for holding the ferrule assembly (110) in the simplified port. The elastic piece is disposed in a peripheral wall of the simplified port and clamped on the ferrule assembly to exert an axial elastic force on the ferrule assembly. The fiber optic connector and the fiber optic adapter of the present invention both can be shortened in length, and the fiber optic connector assembly has a simpler structure than that of a standard fiber optic connector assembly.

Abstract: A method of operation of a navigation system includes: calculating a speed difference value based on a sensor speed measurement and a location speed measurement; generating a speed probability distribution with the speed difference value and the sensor speed measurement calculating a density regression based on a speed density peak of the speed probability distribution; determining a speed adjustment factor from the density regression; and calculating an adjusted sensor speed from the sensor speed measurement with the speed adjustment factor.

Abstract: An assembly for mounting electronic components includes a face plate comprising a thermoplastic material. The face plate includes a retaining element for securing a captive screw and spring assembly for mounting an electronic printed circuit board. The retaining element includes one or more slots adapted to expand the element to permit insertion of the screw and deformation of the hole upon insertion of the screw, while locking the screw to retain the screw in place. This arrangement permits the elimination of the metal standoff frequently used in similar devices. Methods for preparing the assembly and mounting the printed circuit boards are also described.
