摘要： A transmitter device (100) receives an audio signal from an audio source device (112), and transmits the audio signal at a low power over a commercial broadcast channel to a local receiver (120). The transmitter device selects an initial channel by scanning the available spectrum, partitioned into sub-bands (210-206), and measuring the received signal strength in each channel. The channel having the lowest strength is used to set a threshold. The sub-band with most channels meeting the threshold is initially selected, and the channel in the initially selected sub-band with the lowest received signal strength is selected for initial use. A context-based weighting factor may be applied in selecting the initial channel or in selecting subsequent channels when the initial channel conditions degrade.

摘要： Disclosed is a hands-free electronic device including an FM receiver and an FM scanner to continuously scan for FM channels and to locate available FM channels for a list of available FM channels rated according to signal-to-noise ratio (SNR) and/or a received signal-strength indication (RSSI). A short range transceiver may transmit and receive short range communications, from a handheld device. An FM transmitter of the hands-free device can transmit received short range communications via available FM channels of the rated list of available FM channels. The hands-free device may be in communication with, for example, an automobile FM radio. In this way, the car radio may audibly output that which is transmitted from the handheld device. In an embodiment, a speech synthesizer may be configured to generate speech output to indicate an available FM channel from the rated list of available FM channels.

摘要： Disclosed are methods and electronic communication devices, such as an in-car speaker device, that can receive via a downloading process, a communication address list from another device to the memory of the electronic communication device and can append a predetermined communication address to the communication address list. The predetermined communication address, which can be to an automated voice recognition based service, can be annunciated first. Also disclosed are methods and electronic communication devices for determining that a communication is with an automated voice recognition based service and then switching from a first call profile to a second call profile. Such a second profile can include different features such as a change of the frequency response of the audio signal of the electronic communication device, and/or reduction or elimination of the echo control, and/or a change in the noise control of the digital signal process.

摘要： A method (200) for controlling audio signals to an FM transmitter and a loudspeaker of a hands-free adapter first sends a first audio signal to the loudspeaker (242) and measures and records a loudspeaker audible artifact such as echo return loss (244) and/or echo tail length (246). Next, the hands-free adapter sends a second audio signal to the FM transmitter and the loudspeaker (252) and measures and records an FM transmitter and loudspeaker audible artifact such as echo return loss (254) and/or echo tail length (256). If the FM transmitter and loudspeaker audible artifact minus the loudspeaker audible artifact is greater than a threshold (263, 266), the hands-free adapter sends a third audio signal to the FM transmitter only (270), and if the FM transmitter and loudspeaker audible artifact minus the loudspeaker audible artifact is not greater than the threshold, the hands-free adapter sends the third audio signal to both the FM transmitter and the loudspeaker (280).

摘要： A portable hands-free phone accessory (102) provides hands-free operation for a mobile communication device (104), and is operable in an operating mode for providing hands-free operation, and a low power, battery saving mode which does not provide hands-free operation. When the accessory is in the low power mode, it periodically checks to if a phone device has come within a hands-free range (204). When a phone device is detected, the accessory powers up for hands-free operation. When the accessory in the operating mode, and detects that the phone has moved away from the accessory (304), the accessory powers down to the low power mode.
