Auto Locating Emergency Rescue Transmitter (ALERT), is an automatic emergency signal generator that broadcasts a radio frequency (rf) signal that can be locally received across the entire AM band spectrum for guiding rescuers to the location of a distressed automobile, aircraft or other vehicle that may also be outside of anyone's cognizance. The preferred embodiment includes an additional amplifier/modulator with a pre-recorded voice or tone-coded message that may be installed in or provided as an adjunct to the vehicle's existing radio. To use this embodiment, rescuers may determine the location of the distressed vehicle by standard rf signal tracking techniques. However, using recently available technologies, an alternate embodiment provides map grid co-ordinates to rescuers via a link to the Global Positioning Satellite (GPS) System. In either embodiment activation of the system is accomplished via an inertia switch or manual override switch in the vehicle. In later model automobiles the inertia switch is already also present to activate the air bag. This switch may be redundantly linked to the ALERT system.

[ What is claimed is:] [1.]1. An automatic locating emergency rescue transmitter (ALERT) for a vehicle having a power supply comprising:a. an antenna;b. an IF signal/power amplifier, designed for transmitting over the entire AM frequency band, connected to said antenna;c. a normally open inertia switch connected to said IF signal/power amplifier; said inertia switch designed to be closed by a damaging accident;d. a normally closed master switch connected in series between said power supply, and said inertia switch; said master switch designed to be manually opened and closed;e. a distress signal modulator, connected to said inertia switch;f. a normally open test switch connected in parallel to said inertia switch; said test switch designed to be manually opened and closed andg. a distress signal contained in said distress signal modulator; said distress signal being an alternating pre-recorded voice message and tone signal; reby, when said master switch is closed and said inertia switch or said test switch is closed, said distress signal modulates said IF signal/power amplifier and said distress signal is sent to said antenna, where said distress signal is repeatedly and continually broadcast for reception by all operating AM receivers within reception range; and when said master switch is opened, nothing will be broadcast no matter what the state of said inertia switch and said test switch.
