摘要： The invention concerns a system (100) and method (400) for operation of a voice activity detector (230). The system can include a speaker (105), a first microphone (110) and a second microphone (120) in which the first microphone and the second microphone can capture acoustic output from the speaker. The system can also include an adaptive module (220) in which the first microphone and the second microphone can provide signals to the adaptive module, and the adaptive module can provide an input to the voice activity detector. The adaptive module can receive a first input (242) from the first microphone and a second input (243) from the second microphone and can attempt to determine (430) a transformation between the first and second inputs for setting a configuration of the voice activity detector.

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 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.

摘要： A speaker (100) having a diagnostic capability, as well as a circuit (101) and related methods (500) for performing speaker diagnostics based upon a driving-point impedance are provided. The speaker includes a flexible cone (104) and a voice coil (106) connected to the flexible cone for driving the flexible cone so as to convert electrical signals into sound. The speaker also includes a signal source (110) connected to the voice coil for supplying a test signal to the voice coil. The speaker further includes a signal sensor (112) electrically connected to the voice coil for sensing a response signal occurring in response to the test signal. Additionally, the speaker includes a condition determining module (114) for determining a driving-point impedance based upon the response signal and for comparing the driving-point impedance to a predetermined impedance to thereby determine a condition of the speaker.
