First Claim
Patent Images
1. A protective mask communication device for use in hazardous environments, with a protective mask that is adapted to be worn over a person'"'"'s face and to supply air to the wearer, comprising:
- a housing construction to be mounted on the protective mask, and, disposed within the housing,a microphone, in acoustic communication with the interior of the mask, and a speaker, in acoustic communication with the wearer'"'"'s ear,a transceiver constructed to transmit and receive relatively low power signals to and from another similar communication device located nearby, and to transmit and receive relatively higher power signals to and from a remote transceiver located relatively further away than said similar communication device, andcircuitry constructed to process the signal received from the microphone and supply an input signal to the transceiver.

Abstract
Protective mask communication systems are provided for use in hazardous environments, e.g., firefighting and hazardous waste clean-up operations. The systems allow wearers of protective masks working in a hazardous area to readily communicate both with each other and with personnel and automated systems outside of the area. Preferred systems provide short range radio communication between mask wearers.
