Abstract: A personal monitoring system to be worn by an individual in a hazardous situation comprises an enclosed face mask which includes a transparent shield over at least the eves a sensor module secured to the individual which includes a plurality of sensors, a microprocessor and an RF transmission means operable to transmit data obtained by the sensors. The face mask includes a heads-up display comprising a housing containing an electroluminescent display panel, an optical lens, a microprocessor, and an RF receiver operable to receive data from the sensor module. The housing is configured to allow the mounting of the display panel and optical lens in a spaced-apart arrangement so that the display panel is viewed through the lens. The system of the invention also includes a central Incident Commander Module comprising an RF transceiver and a display panel which can receive and display sensor data from a plurality of head-worn devices.

Abstract: The present invention relates to a digital situation indicator, especially a personal monitoring and alarm system. The digital situation indicator according to the invention consist of three parts: sensor module (SM) for monitoring desired data, heads-up display module (HUD) mounted in a facemask (F) or helmet of the operating person, and incident commander module (ICM) at a distance from the operating person. The digital situation indicator can be used to monitor for example firefighter's heat stress, amperage in a welding machine or warfighter's dosage of chemical warfare agents.
