Abstract: A warning system for making known the presence of an emergency vehicle. A transmitter is mounted in an emergency vehicle that outputs a digital UHF/LMS signal that is detectable within a range. A receiver responds to the digital UHF/LMS signal from the transmitter and is mounted, most preferably to a dashboard of a motor vehicle. The receiver detects from the digital signal the type of emergency vehicle from which the digital signal is originating. In one embodiment the digital signal also includes a unique identifier for the transmitter rather than simply a generic discipline identifier such as police, fire, emergency etc. A visual indicator mounted to the motor vehicle is activated in response to the digital signal from the transmitter to warn a motorist in the motor vehicle of a presence of the emergency vehicle within the range of the transmitter and to warn the transmitting vehicle of the presence of other emergency vehicles within receiving range.

Alert signals are preferably repeated by other incursion detectors wherein the distance and conditions over which the alert signals may be communicated is extended. A validation circuit and tilt sensor filter out not incursion events such as wind tipping. The incursion detectors may generate area alerts, or personal alerts and can transmit operational status and alerts to discrete groups of receivers.

Abstract: Disclosed is a method and circuit for repetitively firing a flash lamp. The method utilizes a power supply having a periodic voltage signal. The method times the discharge of the flash lamp to occur when the power supply signal is below the flash lamp self extinguishing voltage such that the flash lamp de-ionizes while the power supply signal remains below the self extinguishing voltage, thus preventing afterglow. The circuit utilizes a means for detecting when the voltage of the power supply voltage signal falls below the self extinguishing voltage to trigger the flash lamp. An additional embodiment adds a means for interrupting current flow in the flash lamp before the voltage across a storage capacitor falls below said self extinguishing voltage. The method and circuit may be extrapolated for use with other electromechanical devices.
