Methods and systems for instrument landing system (ILS) alerting. The method may include: receiving an ILS localizer signal and traffic information; monitoring a signal-quality of the received ILS signal; annunciating on a display system onboard the aircraft an impending ILS auto-pilot disconnect alert when the signal-quality is determined to have decreased by more than a threshold; associating the ILS signal with stored ILS antenna information to thereby construct a three-dimensional ILS envelope with a point of origination at a location of an ILS localizer; presenting a map showing the aircraft at a current location, and the runway; and, using the traffic information to monitor a location and movement of an intruder traffic and predict an infringement of the intruder traffic on the ILS envelope. Responsive to the predicted infringement, the method may annunciate an ILS alert and transmit a notification to air traffic control or the intruder traffic.

Systems and methods for alerting for an instrument landing system (ILS)

A transmission line transmits light from a remote source to a light sensor affixed to a display unit to provide a variation in the display characteristics of the display unit based at least in part upon the remote light intensity. A reception end is integrally formed as part of the transmission line and is physically separated from the light sensor. The reception end gathers the remote light for transmission by the transmission line. An emission end is integrally formed as part of the transmission line and presents the remote light, transmitted by the transmission line, to the light sensor such that the variation in the display characteristics of the display unit may be provided based at least in part upon the remote light intensity.

Methods and apparatus for adjusting the display characteristics of a display unit

Methods and apparatus for controlling the brightness level of a lamp in a backlit LCD display include primary and secondary controllers. The primary controller establishes the arc drive to the lamp to achieve the desired lamp brightness. The primary controller includes a desired brightness set-point as a first input, and a feedback signal corresponding to actual brightness detected at the lamp as a second input. The primary controller operates in real time, essentially adjusting the lamp arc drive instantaneously as a function of the detected brightness feedback signal. The secondary controller is employed to fine tune the control of the lamp by determining whether the desired brightness level may be achieved more efficiently. The secondary controller varies one or more parameters, such as temperature, within the lamp to achieve the optimum operating point of the lamp at the desired brightness level.

Methods and apparatus for controlling the intensity and/or efficiency of a fluorescent lamp

Disclosed is a control mechanism for regulating the temperature of a fluorescent lamp tube located within a housing. The control mechanism includes a cold spot mechanism defining the cold spot of the lamp tube, a heating mechanism, a power supply and a temperature sensor. The heating mechanism is connected to the power supply and is contiguous with a portion of the cold spot mechanism located outside of the housing. The temperature sensor is also coupled to the power supply and monitors the temperature of the cold spot mechanism. Based upon the temperature of the cold spot mechanism, the temperature sensor operates the power supply, so as to deliver power to the heating mechanism to warm the cold spot mechanism and maintain a cold spot temperature that allows the lamp tube to generate maximum visible light output.
