Abstract: A control system and method of selectively enabling an auto-shutoff feature of a control system for an aviation headset includes a power switch. The power switch is toggled and if the control system is in a powered down state, a startup sequence for the control system is initiated. During the startup sequence, a bias voltage detector checks for a bias voltage on a signal line of the headset. If a bias voltage is detected during the startup sequence, the auto-shutoff feature is enabled. The auto-shutoff feature periodically checks for a bias voltage and powers down the control system if no bias voltage is detected for a predetermined time interval. If no bias voltage is detected during startup, the auto-shutoff feature is disabled.

Abstract: A method of managing communications between communication devices within a digital intercom system includes providing input and output tables for each communication device. The tables for each device are made up of cells formed from linear arrays corresponding to communication channels and the other devices. When two devices communicate on a given channel, a cell in the appropriate input and output table is identified based on the channel and the devices communicating. The cells provide volume control information which can be relied upon to determine if or to what degree audio signals should be transferred between the devices.

Abstract: A digital intercom system has first and second master stations. Each master station has hardware and software configured to allow duplex communication between a plurality of communication devices. The software is further configured to run a plurality of settings for directing communication between the communication devices of each master station. The master stations are configured to allow duplex communication between the devices of each master station. Inter-master channels define parameters for communication between the communication devices of each master station. The settings of the master stations can be modified based on input entered into a browser based program run on a first input/output device by a user.

The software is configured to run a plurality of settings for directing communication between the communication devices, the settings including a plurality of channels for each communication device. The channels each define parameters for how the communication devices within the system will communicate. An audio output device is linked to a corresponding communication device of the plurality of communication devices such that the audio output device is configured to receive and play the same audio as the corresponding communication device. The master station is configured to modify the settings based on input entered into a browser based program run on an input/output (I/O) device by a user.

Abstract: An intra-aural audio device includes an outer layer shaped to define separate ear canal, concha bowl, and concha cymba portions. An inner layer is disposed within the outer layer, the inner layer having a durometer different than that of the outer layer.

Abstract: A wireless communication system and method provide wireless communication between a first communication component and a second communication component. In at least one of the first and second communication components, strength of a signal between the first and second communication components is monitored. If the strength of the signal drops below a threshold, an alert is generated.

Abstract: A communication system and a voice activation system and method for the communication system include a headset and a microphone. The voice activation system includes an adjustable first input voltage and a second input voltage. A controller compares the adjustable first input voltage and the second input voltage and generates an alert indicating an adjustment to the adjustable first input voltage.

Abstract: A communication headset includes first and second domes. The first and second domes include the speaker assembly having a first speaker coil and a second speaker coil. One speaker coil is for receiving a first audio signal, and the second speaker coil is for receiving a second audio signal and an active noise cancellation signal. Each of the speaker coils co-acts with a magnetic field to cause a diaphragm to move responsive to the first and second audio signals and the active noise cancellation signal individually or simultaneously. When the first audio signal is detected, a controller disconnects the second audio signal from the first dome of the headset.

Abstract: A method for active noise cancellation in a volume generates a mathematical model of a noise process to be cancelled. Using the mathematical model, a noise signal in a next sample period is predicted from a measured noise signal. The predicted signal is inverted and applied to the volume. Destructive interference of the noise signal and the inverted signal cancels the noise in the volume.
