Transmitter for transmitting personalized message to emergency response vehicle e.g. car, has apparatus sending signal to frequency modulation radio data system traffic message channel, where signals are synchronized with siren of vehicle

摘要

The transmitter has an apparatus sending a signal to a frequency modulation radio data system traffic message channel (FM RDS-TMC). Device signals are synchronized with a siren of an emergency vehicle. A windscreen without special wiring is powered by rechargeable batteries and/or connected to a cigarette lighter and includes a directional antenna. An universal serial bus (USB)input is connected to a personal computer (PC). A modulator sends RDS-TMC codes in order to cover a maximum of receivers.
