20130295853 | COMMUNICATION SYSTEM AND METHOD HAVING LOW-SIGNAL-LEVEL WARNING SYSTEM AND METHOD - 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. | 11-07-2013 |
20120224709 | VOICE ACTIVATION SYSTEM AND METHOD AND COMMUNICATION SYSTEM AND METHOD USING THE SAME - 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. | 09-06-2012 |
20090141906 | Communication Headset Processing Multiple Audio Inputs - 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. | 06-04-2009 |
20090136052 | Active Noise Cancellation Using a Predictive Approach - 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. | 05-28-2009 |
