    摘要: Methods and apparatus are disclosed for communicating between an aircraft and a terminal when the aircraft is on the ground. The connection between the aircraft and the terminal is made over a ground power line while the aircraft is being supplied with power. The ground power line comprises one or more wires, which are typically unshielded and cause radio interference. At the transmitting end, multiple copies of the same signal offset in phase relative to one another over the ground power line. Each data stream is coupled to a respective wire in the ground power line. At the receiving end, the multiple copies of the signal are extracted from the respective wires of the ground power line and combined to generate a combined signal with improved signal-to-noise ratio. Radio interference is suppressed by transmitting the data streams in a phase offset manner so that the unwanted emissions cancel.

    摘要: A system and method for analyzing aircraft 602 operation and maintenance history 226 in light of maintenance reports, aircraft 602 type system failure history, health management reports, and aircraft 602 exterior structural conditions to produce a real time recommendation regarding aircraft 602 maintenance and dispatch. A visual inspection 250 report is generated by capturing a real time image of an exterior of the aircraft 602, inverting the real time image, superimposing the real time image on a previous image of the aircraft 602 exterior, and detecting any variation on the combination of superimposed inverted image on the previous image of the aircraft 602 exterior. Aircraft 602 type historical systems failure reports are analyzed to identify any predictive latent system failure of the aircraft 602 based on the aircraft 602 type historical systems failure report and aircraft 602 operation history and maintenance history 226.

    摘要: A method and apparatus is provided for communicating data over a ground power line between a vehicle and a ground terminal. In one example, a first power unit detects a signal indicating connection between the first power unit and a remote power unit. Responsive to detecting the signal, one or more modems associated with the first power unit automatically establish a data connection with one or more remote modems associated with the remote power unit. After establishing the connection between the one or more modems in the first power unit and the one or more modems in the remote power unit, the one or more modems in the first power unit exchange data with the one or more modems in the remote power unit over the power line. In one example, the first power unit may comprise an onboard power unit in a vehicle (e.g., aircraft) and the remote power unit may comprise a ground power unit. Alternatively, the first power unit may comprise a ground power unit and the remote power unit may comprise in a vehicle (e.g., aircraft).

    摘要: Methods and apparatus to provide transient event protection for circuits are disclosed. An example apparatus includes a first clamp circuit. The first power circuit provides a first reference voltage. The first clamp circuit directs energy from a signal node to the first power circuit in response to a transient resulting in a voltage at the signal node being lower than a second reference voltage. The apparatus also includes a second clamp circuit. The second clamp circuit includes a transistor. A collector terminal of the transistor is prevented from having a lower voltage than the second reference voltage. A second power circuit provides the second reference voltage, which is lower than the first reference voltage. The second clamp circuit directs energy from the signal node to the second power circuit in response to a transient resulting in the voltage at the signal node being higher than the first reference voltage.
