Abstract: An aircraft solid state power controller comprises a feed node to be electrically connected to a primary electric power supply; a load node to be electrically connected to at least one electric load; and at least one electric switching device, in particular a solid state switching device, which is arranged between the feed node and the load node. The at least one electric switching device is switchable between an on-state, in which the at least one electric switching device provides a low-resistive electric connection between the feed node and the load node; and an off-state, in which the at least one electric switching device electrically isolates the load node from the feed node.

Abstract: A method and system for employing client interfaces for packages. In one embodiment, an access object associated with a service provided by a first package is located, where the service is seeking to access content residing at a second package. A client interface is then created at the second package using the access object. The client interface is used to provide access to the content by exposing the content to the service via the client interface.

Abstract: A method and system for object generation in packages. In one embodiment, the process for generating an object in a package is initiated. The package is created and is associated with a target package. The object is generated into the package.

Abstract: A method and system for executing calls and return calls using client interfaces for packages. In one embodiment, a service at a service package is called using a client interface at a client package. The return call is then made on object using the client interface at the client package as performed by the service at the service package.

Abstract: A system and method are provided for interacting with a persistence layer. In an embodiment, a persistence layer may receive a representation of Enterprise Java Bean (EJB) metadata. The persistence layer may determine whether the representation of Enterprise Java Bean (EJB) metadata is compatible with a version of the EJB specification. In an embodiment, a representation of an Object-Relational (OR) mapping schema may be generated based, at least in part, on the representation of EJB metadata.

Abstract: Methods and apparatus, including computer program products, for defining and using data types at runtime. A procedural source code program is compiled to generate a compiled program having instructions to create a runtime data type and to use the runtime data type. The runtime data type has a compound structure of referenced data types. Instructions to create a runtime data type having a compound structure are executed by creating a runtime data type definition from the compound structure of referenced data types by resolving the referenced data types bottom up into data types known at runtime. A data object having the runtime data type is created. Type checking is performed on uses of the data object at runtime according to the runtime data type.
