Abstract: A set of stators of a linear induction motor are mounted on a track. A three-phase current is provided to each of the stators, such that a traveling magnetic field (TMF) is created by the stators along the length of the track. The traveling magnetic field includes a magnetic flux corresponding to a stator excitation modulated with a message signal. A rotor includes a series of conductor plates. As the traveling magnetic field passes through the conductor plates, a current is induced in the plates by induction. Such current then generates an opposing magnetic field causing the plates and the vehicle to be propelled. Each phase may first be modulated with a message signal, before being provided to the stator. The current at the rotor is then demodulated to realize the message signal. A doppler shift due to the speed of the rotor relative to the stator is corrected.

Abstract: A system for an airborne platform includes a display device, an input device, and an image processing circuit. The display device is configured to display a visualization provided as a pixel matrix capable of being virtually rotated along a horizontal axis or along a vertical axis based on a user input. The input device is configured to receive user input providing an indication to virtually rotate the visualization along at least one of the horizontal axis and the vertical axis. The image processing circuit is configured to receive pixel data corresponding to the pixel matrix, receive the user input from the input device, determine an offset angle to virtually rotate the visualization along the horizontal axis or the vertical axis, configure the visualization in response to the determined offset angle, and output the configured visualization for display on the display device.

Abstract: A digital radio frequency (RF) modulator provides modulation for base-band TV signals. The RF modulator provides direct conversion of digital base-band audio and video signals to a desired RF channel frequency, without any analog up conversion. The RF modulator includes an audio module, a video module, and a RF converter. The audio module includes a pre-emphasis filter, a multi-stage audio interpolator and a complex frequency modulator to generate frequency modulated (FM) audio signals. The video module includes a complex VSB filter, a group-delay compensation filter and some processing logic to generate a filtered output video signal. The RF converter includes a complex adder, a complex multiplier and a RF interpolator to construct the base band TV signals and to shift the base band TV signals in a frequency domain to the desired RF channel frequency. The exponential video carrier is generated at baseband and has a frequency whose value is in the range of +/?13.5 MHz.
