Embodiments are directed to systems and methods for utilizing aircraft cockpit and cabin lighting to provide both power and data transmission to occupants. Data and power may be transmitted on non-visible and/or visible spectrums. The visible light may be used independently for aircraft illumination. Data for the cockpit allows for quick upload and download of flight planning and maintenance data to an electronic flight bag. The electronic flight bag may also be able to receive power from cockpit and cabin lighting during flight.

In an optical fiber monitoring system which detects physical disturbance or other parameters such as temperature or strain of a fiber where a monitor signal is transmitted along the optical fiber and analyzed to detect changes which are indicative of an event, a method is provided for periodically checking proper operation of the optical fiber monitoring system. :A fiber disturbance actuator periodically causes a pattern of disturbances of a portion of the fiber at a predetermined location thereon where the disturbance is characteristic of the event to be monitored. The monitor signal is analyzed to detect the pattern of changes and in the event that expected changes are not detected, a warning is issued that the intrusion detection system is not properly operating.

A transmission apparatus executes a reception processing that receives a first alarm detected in a first transmission apparatus different from the own apparatus from among a plurality of transmission apparatus from a second transmission apparatus different from the own apparatus from among the plurality of transmission apparatus, executes a detection processing that detects a second alarm of the own apparatus, executes a mask processing that masks alarms including the first alarm received by the reception processing and the second alarm detected by the detection processing, and executes a sending processing that sends an alarm that is not masked by the mask processing from among the alarms to a third transmission apparatus different from the own apparatus and the second transmission apparatus from among the plurality of transmission apparatus or sending the alarm to a given apparatus different from any of the plurality of transmission apparatus.

A monitoring device 1 includes an individual alarm reception unit 10 configured to receive individual alarms issued from a plurality of devices constituting an optical transmission network, a table 20 in which a search operator for searching for necessary information, that is information required for treating the individual alarms in the same manner when specifications of the individual alarms are different from each other, is associated with information included in the individual alarms, a search operator extraction unit 30 configured to extract the search operator using the information included in each of the individual alarms as a key, a rule 40 in which the search operator is associated with the necessary information; and a unified alarm information generation unit 50 configured to search the rule 40 using the search operator as a key, compare the information included in the individual alarms with the necessary information corresponding to the search operator, and add information, that is included in the necessary information but not included in the individual alarm, to the individual alarm to generate unified alarm information.
