Abstract: The present techniques provide light emitting assemblies that include two or more light emitting devices joined into a single multilayered structure. Each device is electrically contiguous, and includes an electroluminescent polymer layer between two electrodes. In each device, the electroluminescent polymer layer and/or at least one of the two electrodes is patterned to form an illuminated design. Each device may be separately energized to illustrate a different pattern or design. In some embodiments, a layer having a contiguous light emitting layer may be attached to the back of the multilayer structure.

Abstract: A security monitoring system 10 for a large infrastructure 12 is provided. The system includes several magnetometers 14 disposed around an area 16 of the infrastructure. According to aspects of present technique at least one magnetometer 28 is configured to relay an alert signal indicating a change in a magnetic flux profile around the area. A central unit 56 is configured to receive the alert signal from at least one magnetometer and initiate a response to the alert signal.

Abstract: An on-board monitor for a railroad locomotive is disclosed. The on-board monitor interfaces with the controller subsystems of the locomotive to collect parametric performance data. The specific data to be collected and the collection intervals are defined at a remote service center and transmitted to the on-board monitor. The on-board monitor also includes the capability to collect additional data or collect data more frequently in response to the results of certain triggering events.
