Abstract: An electrical to audible signal measurement apparatus comprises an absolute value converter, a voltage to frequency converter, a polarity detector, and a waveform changer. The absolute value converter is capable of converting a bipolar input signal into a unipolar signal. The voltage to frequency converter is connected to the absolute value converter and is capable of generating a frequency signal proportional to the unipolar signal. The polarity detector is capable of identifying a polarity of the bipolar input signal to form an identified polarity. The waveform changer is connected to the voltage to frequency converter and polarity detector and is capable of generating a number of different waveforms in an audio frequency range in response to receiving the frequency signal from the voltage to frequency converter and in response to the identified polarity.

Abstract: Methods, systems, and articles of manufacture enable routing a communication from a cell phone associated with a service provider in which the cell phone is located in a predetermined area in which the service provider does not have an operational base station or in which routing assistance is required. A cell base station having one or more antennas is provided in an aircraft. Each of the antennas is configured to monitor a respective sector of the predetermined area for a cell phone communication when the aircraft is flown in proximity to the predetermined area. A registration request from a first cell phone in the predetermined is detected via the cell base station and an ID and location associated with the first cell phone is routed to a ground based telephone switching office, such as the mobile telephone switching office associated with the service provider of the detected cell phone.

Abstract: A digital message analysis tool for incorporating a digital message standard into a relational database. The tool includes a message standard automation module (MSAM), a message implementation module (MIM) in communication with the MSAM, and, a platform interoperability module (PIM), in communication with the MSAM. The MSAM includes a digital message standard. The MSAM automates the digital message standard into a relational database and provides a first graphic user interface (GUI) that allows a user to view the desired contents of the digital message standard and requirement interdependencies associated within the digital message standard. The MIM includes a second GUI. The MIM develops and provides a message implementation in accordance with the digital message standard. It utilizes the message implementation for providing a message implementation report. The PIM includes a third GUI.
