Abstract:
Control and monitoring of airfield lighting from a control tower and other maintenance/supervisory locations uses double loop self healing fiber optic communications circuits to enhances speed of operation even with large and complex airfield lighting system requirements, and significantly increased reliability and operating lifetime thereof. A plurality of local light control and monitoring groups are used, wherein each group has at least one fiber optic communications concentrator that independently communicates with light controllers within the group and the remote supervisory control and monitoring systems in the control tower and other locations. This allows faster control response of the lamps in each of the airfield light fixtures, and monitoring concentration of operational data within each group. Each of the at least one fiber optic concentrators is optically coupled to double loop self healing fiber optic communications backbone circuits coupled to main and backup computer supervisory control systems for redundancy purposes.
Abstract:
A lighting unit includes a housing, a lamp fixture configured to be coupled to the housing, an element extending from the lamp fixture and configured to be received in the housing, and a sealing member defining an aperture for receiving the element therethrough. A periphery of the aperture forms a fluid-tight seal around the element. In another aspect, a lighting unit includes a housing and an enclosure coupled to the housing and configured to define an interior space, wherein the interior space is sealed from an interior of the housing. In another aspect, a method for sealing a lighting unit includes providing a housing, an enclosure coupled to the housing, and an opening in the housing in communication with the enclosure, placing a seal between the housing and the enclosure, and applying a sealing member to the opening to seal the opening.
Abstract:
Magnetic component assemblies including moldable magnetic materials including surface mount termination features, as well as manufacturing methods therefor, are disclosed that are advantageously utilized in providing surface mount magnetic components such as inductors and transformers.
Abstract:
Lanyard connectors for release of an ordinance are provided. The lanyard connectors include a coupling sleeve and locking ring movable between a first position and a second position. The lanyard connectors also include a latching spring and a reset spring. The latching spring is partially disposed within a groove in the locking ring in the first position, and removed from the groove in the second position. The reset spring is held in place by a connector cover and interfaces with a second groove in the locking ring. The reset spring is compressed in the second position. The lanyard connectors allow for release of an ordinance receptacle when in the second position. Methods of using the connectors are also provided.
