Abstract: A liquid natural gas tank (LNG) pressure management system is provided. The system includes an LNG bulk tank, an LNG fuel tank operably connected to the LNG bulk tank, a compressed natural gas (CNG) accumulator operably connected to the LNG fuel tank and a liquid natural gas cryogenic pump operably connected to the liquid natural gas fuel tank and the liquid natural gas bulk tank. The pressure management system is configured to direct boil off gas (BOG) to the compressed natural gas accumulator upon a predetermined condition.

Abstract: A connector assembly for blind mated back plane interface connections of optic fibers with active optical devices includes a shroud mounted in a back plane panel within which are received a receptacle assembly mated to connector modules. The modules, each associated with a cable of a plurality of optical fibers, subdivide the mated fibers into separately connected groups to avoid expensive tolerance requirements. The receptacle includes a housing and shims for precisely locating the active optical devices relative to the ends of the optic fibers. The interface connections are shielded from interference by conduction between the receptacle housing, a fiber termination ferrule and a rear housing and strain relief portion of each connector module.
