Abstract: A transmitter includes an input, a modulator, and a calibration memory configured to store discrete calibration test points. A compensator is coupled between the input and the modulator and cooperates with the calibration memory to cause the modulator to generate a respective calibration carrier signal for each of the discrete calibration test points during a calibration phase. A detector is coupled to an output of the modulator and is configured to determine respective calibration values of the calibration carrier signals during the calibration phase. A compensator calculator is coupled to an output of the detector, and is configured to generate compensation values for the compensator for use during an operation phase and based on the calibration values of the calibration carrier signals.

Abstract: A method for creating and transmitting electronic medical data from a remote location, such as a battlefield, to a remotely located central data facility. The method can begin by entering the personal identification data for an injured person into a portable handheld computer. Responsive to voice commands, data input fields are selected and populated. The data can be inputted into the computer via a touch screen or via the microphone. A recording may be made, with a camera included in the portable handheld computer, of imagery associated with the injured person. Thereafter, an audio recording can be made, recording audio records concerning injuries or treatments of the injured person. Medical data obtained about the injury, as well as patient vitals are associated to form an electronic medical record. The electronic medical record, along with images and audio, is then transmitted over a communications network to update the central database.
