Patent attributes
A system and method is provided for detecting the approach of official and emergency vehicles and alerting drivers. The system is comprised of a vehicle device, a client device, a local device and a dongle. The local device includes a set of acoustic sensors and a set of light wave sensors. The local device is connected to the dongle. The dongle is connected to the local device, the vehicle device and the client device. In use, the sensors record analog light wave and acoustic signals. The signals are processed through a series of rolling frequency and amplitude summary tables to determine the type of emergency vehicle and whether or not it is approaching. If so, an alert is generated and sent to the vehicle device and the client device where it is displayed.
