Abstract: Fault trees are automatically converted to Bayesian networks for assisting in system reliability, failure analysis and diagnostics by using information from the fault tree structure to create the Bayesian network structure, creating parameters of the Bayesian network using information from the fault tree, obtaining information about observation nodes for the Bayesian network from a list of observations that augments information contained in the fault tree, and inserting the observation nodes into the Bayesian network. The fault tree is pre-processed into an intermediate format prior to conversion that may include adding reliability values from a separate text document when the fault tree is in such format that requires it.

Abstract: An aircraft passenger seating arrangement has at least one passenger seat within an enclosure and an aisle located within the enclosure adjacent to the seat with no seats located adjacent to an opposite side of the aisle from the seat. The enclosure has a frame with a symmetrical cross section, the frame having a curved perimeter wherein the height of the cross section is different than the width to minimize cross sectional area of the aircraft body to reduce sonic boom signature.

Abstract: An apparatus and method for use in deploying a wireless communication device is provided that includes an antenna element and a reflector secured proximate a first end of the element. The reflector includes a base, and a flexible wall with a first end positioned proximate the base extending away to a second end positioned about the element. The wall can be deformed from an original position to a deformed position where the second end is temporarily positioned proximate the element and released such that the wall returns to the original position. The method includes deforming the reflector from an original position to an altered position where portions of a rim are proximate the element. The reflector is positioned in contact with the communication device, secured in the altered position, maintained in the altered position with a reduced profile, and released such the reflector elastically returns to the original position.

Abstract: Opto-electronic array modules using a Vertical Cavity Surface Emitting Laser (VCSEL) and photodiode arrays have polished fiber end face angles varying from a 45 degree angle to attenuate the amount of light entering the fiber in order to eliminate saturation of the opto-electronic receiver in a fiber optic transceiver system. Varying angles may be used when coupling light between the fiber and an active device to adjust the attenuation.
