Abstract: A system may have a support structure that separates an exterior region from an interior region. The system may include a lighting system with interior and/or exterior lights with adjustable diffusers. An interior light may be used as a task light, a cabin light, a sensor indicator light, or a trim light. Adjustments to the adjustable diffusers can be used to adjust the angular spread of emitted light for operation in different lighting modes.

Abstract: A system for integrated testing of one or more multi-service communications switches including a script execution environment for executing a test script. The script execution environment includes a hardware definition file storing a number of logical hardware device names corresponding to hardware devices used by the test script, including a system under test (SUT) and a number of hardware testing devices. The system further employs a network definition file including a plurality of logical connection names corresponding to connections between the hardware devices in the test environment. These connections in the network definition file are specified in terms of the logical hardware device names defined in the hardware definition file.
