Abstract: One variation of a preferred system for rendering content on a vehicle includes a display, a memory, a communication module, and a processor. The display is configured to mount adjacent an exterior surface of a vehicle. The memory is configured to store a plurality of executable applications including a vehicle identification application and an application elected by a user. The communication module is configured to download the user-elected application to the memory. The processor is configured to selectively execute applications to control visual content rendered on the display, wherein the display renders vehicle identification information when the vehicle identification application executes, and wherein the display renders additional visual content when the user-elected application executes.

Abstract: A high frequency signal source and method of generating a high frequency signal is disclosed. An output signal is generated from a dielectric resonator oscillator and mixed with an output signal from a voltage controlled oscillator having a predetermined tuning range and part of a phase locked loop circuit to sum the frequencies for creating a final output frequency. A portion of the final output frequency is coupled into the phase locked loop circuit that is phase locked to a reference signal from a crystal reference oscillator. The voltage controlled oscillator has a tuning range that is used to compensate for the dielectric resonator oscillator initial frequency error and drift over temperature and aging while the balance of the bandwidth is used to provide the tuning range on the local oscillator output.
