    摘要: A method for forming buried ion-exchanged waveguides involves a two-step process. In a first step a waveguide is formed at the surface of a substrate using an ion-exchange technique. After formation of the waveguide, a field-assisted annealing is carried out to move the waveguide away from the surface of the substrate so that it is buried in the substrate. Exemplary field-assisted annealing is carried out at a temperature close to the ion-exchange temperature ±10° C. to optimize results.

    摘要: A power generation and distribution system utilizes two or more AC generators each of which may be driven by a separate prime mover such as a turbine. The generators may be driven at different rotational speeds. AC power from the generators may be rectified and applied to a common DC bus. Electrical loads may be applied to the common bus and may establish an electrical power requirement. Allocation of electrical power requirement may be made among the generators based on power available from the turbines.

    摘要: The present invention provides an electrical power distribution system that includes a first primary distribution panel (PDP) connected to a first source of electrical power and a second PDP connected to a second source of electrical power. The second PDP is connected to the first PDP by a conductor. A first ELCU receives signals corresponding to the flow of current through the first PDP to a load. A second ELCU receiving signals corresponding to the flow of current between the first PDP and the second PDP and a third ELCU receives signals corresponding to the flow of current between the second PDP and the first PDP. The first, second and third ELCUs protect the electrical power distribution system from a variety of fault conditions.

    摘要: A control apparatus (202) for a starter/generator (110) of an aircraft electrical power system is provided. During a start mode of operation, AC power is provided by the control apparatus (202) to an exciter stator (114) of the starter/generator (110) which is combined with controlled AC power supplied by a start converter (106) to a main stator (116) of the starter/generator (110) to rotate and start an aircraft engine. Alternatively, during a generate mode of operation after engine start, the control apparatus (202) provides DC power to the starter/generator (110) to produce a regulated voltage output from the starter/generator (110).
