Hand microphones and headsets are installed at each flight crew member station. The hand microphone is designed for close-talking, noise-cancelling applications in high noise level areas. The microphone is packaged in a small molded, black, high-impack phenolic case. A press-to-talk button is located on the upper portion of the case ... Oxygen masks with microphones are installed at each flight crew member station. A push-to-talk button is installed on the captain’s control wheel and on the first officer’s control wheel. The push-to-talk buttons are used to control the oxygen mask microphones when transmitting on the selected communication transceiver or on the audio integrating system.

CONT

MILES is a system the Army uses for wargames. You mount a small box, the transmitter, on the end of the barrel of your weapon, and wear a harness that has several straps on the front and back with infrared receptors on them. You also have a key that is normally in the transmitter to enable it. The transmitter has a microphone in it, and whenever a shot is fired, the sound causes it to fire a coded IR laser beam. The sensors on the harness are wired to a box on the back which detects when you have been hit. If you are, a beeper starts sounding loudly. To turn it off you have to take the key out of the transmitter, thus disabling it, and put it in a switch in the harness. Then you are "dead", and have to wait for an observer to come around with a special key that can reset the harness. They can also use the God gun, which is so called because it can fire pulses that will "kill" you like the other transmitters, but it can also fire pulses that reset your harness(bring you back to life...)

[CP-140. ] The Cord Assembly...(headset/boom mike cord assembly) is 6-ft, rubber-covered, electrical cord assembly which is equipped with an in-line dynamic microphone amplifier, a PTT microphone switch, and an internal carbon-dynamic switch. The double-pole double-throw, carbon-dynamic switch connects the microphone amplifier to the microphone line when a dynamic microphone is used. The amplifier is bypassed by the switch when a carbon microphone is used. The headset/boom mike cord assembly connects the headset and boom mike to the associated interconnecting box amplifier or the secure/unsecure jack box amplifier.
