摘要： An alignment apparatus (110) for sound delivery of an audio device (100) is provided. The apparatus can include a speaker (130) mounted to an underside of a face plate (120) of the device, and a raised appendage (112) on the topside of the face plate. At least a portion of the raised appendage rests against at least a portion of a concha bowl (310) of an ear (230) to align a direction of sound from the speaker through the ear canal when the face plate is pressed against the ear. A positional cue of the raised appendage provides a repeatable reference location for positioning the audio device to align a centerline of the speaker with a centerline of the ear canal when coupled to the ear to maximize audio performance.

摘要： The invention concerns a method (500) and system (100) for suppressing receiver audio regeneration. The method (500) includes the steps of receiving a communication signal (502), at a Radio Frequency (RF) unit (102), demodulating the communication signal to an audio signal (504), monitoring a volume level of the audio signal (506), and shifting the pitch of the audio signal when the volume level reaches a predetermined threshold (508), and playing the pitch-shifted audio signal out of a speaker to produce a pitch-shifted acoustic signal (510). The method can shift the pitch of the audio signal to produce a pitch-shifted acoustic signal with signal properties suppressing regeneration of the acoustic signal onto the audio signal at the RF unit. The amount of pitch-shifting can be a function of the volume level.

摘要： The invention concerns a method (200) and a system (100) for ensuring audio safety in an audio device (110). The system includes a processor (112), a sensor (116), an analog safety circuit (114) and a first feedback loop (117). The processor is programmed to output an acoustic output signal (310, 410), the sensor monitors the acoustic output signal and the analog safety circuit is coupled to an output of the processor. The first feedback loop feeds the monitored acoustic signal from the sensor to the analog safety circuit. The analog safety circuit adjusts from a first level (312, 412) to a second level (316, 414) the acoustic output signal when the acoustic output signal exceeds a predetermined safety threshold (314, 420) such that the audio device has an output capacity that is capable of driving a sound pressure level of the acoustic output signal above the predetermined safety threshold.

摘要： An active noise cancellation aircraft headset system. A speaker is mounted within each earcup of a headset for receiving and acoustically transducing a composite noise cancellation signal. A microphone is also mounted within each earcup for transducing acoustic pressure within the earcup to a corresponding analog error signal. An analog filter receives the analog error signal and inverts it to generate an analog broadband noise cancellation signal. The analog error signal is also provided to an analog to digital converter, which receives the analog microphone error signal and converts it to a digital error signal. A DSP takes the digital error signal and, using an adaptive digital feedback filter, generates a digital tonal noise cancellation signal. A digital to analog converter then converts the digital tonal noise cancellation signal to an analog tonal noise cancellation signal so that it can be combined with the analog broadband noise cancellation signal. The resultant composite cancellation signal is provided to the speakers in the earcups to cancel noise within the earcups. The broadband analog cancellation is effective to reduce overall noise within the earcup, and the DSP not only provides active control of the analog cancellation loop gain to maximize the effectiveness of the broadband analog cancellation but also uses the adaptive feedback filter/algorithm to substantially reduce at least the loudest tonal noises penetrating the earcup, including engine and propeller noises, as well as harmonic vibrations of components of the aircraft's fuselage.

摘要： The invention concerns a method (200) and a mobile unit (100) for a rapid initiation sequence. The method can include the steps of receiving (210) a rapid initiation sequence command and in response, bypassing (212) a normal initiation sequence in favor of a rapid initiation sequence such that only those components of the mobile unit that are necessary to permit a user to initiate a call from the mobile unit are initially activated. As an example, the initiated call can be an emergency call to an emergency operations center (132). The method can also include the step of completing (220) the normal initiation sequence once the rapid initiation sequence is completed.
