  • Safety Alarm system
    Publication number: 20060103541
    Abstract: A safety alarm system for use on moving vehicles and heavy equipment provides an added level of safety by not only indicating motion, but by adding a distinct audible warning according to a selected sound pattern template when danger is imminent to those in the local area of potential danger. The sound pattern is selected on the basis of signals from various combinations of signals detected from an object detection sensor and an ambient noise level sensor, thereby providing enhanced safety in the work environment.
