20140261404 | Amplifier Mount for a Closed-Circuit Breathing Apparatus Mask - A component in a mask in a closed-circuit breathing apparatus includes a lever that actuates a wiper in the mask as well as mount for a communication amplifier. The combined amplifier mount and actuating lever can reduce the profile of the means of actuating the wiper and provide an alternative to using chemical means for preventing the deposition of condensation on the inside of a viewing lens of the mask. | 09-18-2014 |
20140180686 | SELF CONTAINED BREATHING AND COMMUNICATION APPARATUS - A self-contained breathing and communication apparatus is described that can facilitate communication between a first user and a second user. A microphone can record sound when the first user speaks. The microphone can convert the recorded sound to a voice signal. A voice activity detection processor can detect spoken words and informative sounds of the first user from the converted voice signal. For this detection, the voice activity detection processor can remove noise from the voice signal. A voice-to-text processor can convert the detected words and informative sounds to a text message. A transmitter of the transmitting module can transmit the text message to a receiver of the second user via a communication network. A display device of the second user can display the text message on a graphical user interface. Related methods, apparatus, systems, techniques and articles are also described. | 06-26-2014 |
