22. A method of facilitating short range communications among members of a working group where each member in the group is wearing emergency equipment including a face mask, comprising the steps of:
-
(a) providing each member of the group with i) a wireless transmitter and locating the transmitter in a position relative to the user'"'"'s mouth to enable the transmitter to detect the user'"'"'s voice;
ii) a transceiver capable of receiving signals from the transmitter and transmitting the received signals to other transceivers worn by members; and
iii) a speaker associated with the transceiver so that signals broadcast from the transceiver may be audibly perceived; and
(b) transmitting signals from a transmitter to all of the transceivers in the working group. - View Dependent Claims (23, 24, 25, 26)

27. A communications apparatus for use in a noisy environment, comprising:
-
a face mask comprising a resilient material configured for providing an effective seal around a wearer'"'"'s mouth and nose to define an interior space between the face mask and the wearer;
a first wireless transmitter module associated with the face mask, said first transmitter module comprising a first microphone located entirely within the interior space;
a second module located externally of said interior space, said second module comprising a second microphone in communication with the first transmitter, and a second receiver, wherein said second microphone detects ambient noise and generates signals corresponding thereto. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)

36. A communications apparatus for use with equipment worn by workers in dangerous environments wherein the equipment includes a face mask, comprising:
-
a wireless transmitter operatively associated with the face mask;
a transceiver capable of receiving signals from the transmitter and transmitting the received signals to other transceivers;
a speaker associated with the transceiver so that signals broadcast from the transceiver may be audibly perceived; and
an activation switch located entirely within the face mast associated with the transmitter, said activation switch including a lanyard attached to the switch wherein the lanyard extends beyond the periphery of the face mask.

37. A communications system for use by emergency workers defining a working group in a WPAN, comprising:
-
for each worker in the WPAN, a face mask, and a short range transmitter operatively associated with said face mask so that communications from a worker wearing said face mask are transmitted to other workers in the working group, said short range transmitter including a microphone, a short range receiver and a speaker associated with the receiver;
for at least one worker in the WPAN, a short range adaptor receiver, said short range adaptor receiver having an output connected to a relatively longer range transmitter, said short range adaptor receiver having an activation switch to switch said receiver between first and second modes;
wherein, in the first mode communications between workers in the WPAN are not broadcast from the longer range transmitter, and in the second mode, communications between workers in the WPAN are transmitted from the longer range transmitter. - View Dependent Claims (38)
