Abstract: A mobile communication device (100) is attached to an audio accessory (114, 124) and characterizes the audio response of the audio accessory. Upon detecting attachment to the mobile communication device (204), the mobile communication device plays an audio test regimen over the speaker of the audio accessory (210, 212, 214, 216, 218, 220). Once the audio accessory's spectral response is known, the mobile communication device may adjust audio processing filter coefficients used in processing audio signals played over the audio accessory.

Abstract: A mobile communication device (100) contains a local wireless controller (114) for operating with a remote audio processor (124). The remote audio processor is used for listening to and speaking with remote parties via the mobile communication device, and operates in a mode having a relatively long latency in communicating with the mobile communication device. Upon receiving a dispatch call (306), a baseband processor (108) of the mobile communication device notifies an application processor (110) with a high priority dispatch notification (122). The high priority dispatch notification causes an active link to be established between the mobile communication device and remote audio processor sooner than if were to occur with ordinary call processing.

The pad (400) can be either wired or wireless and can be used to deliver therapeutic body stimulation as well. In another embodiment, the wireless device (101) controls at least one stimulator pad (400, 500) independent of any incoming signal received.

Tones are output according to a first interactive test profile presented on a user interface during a first test period. A first interaction forms a first adjustment profile with adjustment levels. The audio signal is output with parameters adjusted according to the first adjustment profile. The audio signal is output from the device in accordance with the first adjustment profile and a second interactive test profile. An interaction with the user interface forms a second adjustment profile having second adjustment levels and the audio signal is then adjusted in accordance with the second adjustment levels. The second interactive test profile includes a speech sample and an intelligibility parameter including a spectral tilt for the device and a formant sharpening profile.

The method can include the steps of detecting (312) at a mobile unit (110) the existence of at least one marker associated with a potential emergency, determining (314) whether the marker has reached a predetermined threshold and if the marker has reached the predetermined threshold, initiating (318) an emergency signal to potentially provide searching personnel with a location of a user of the mobile unit.

In addition, the emergency signal can be a vibrational signal, an acoustic signal or a radio frequency signal.

Abstract: A universal notifier (115) is individualized with an appended custom tag so that users may recognize calls intended for them. When a call transmitted from a communication device (101), is received by a recipient communication device (103), the universal notifier, for example an existing private call receive tone, is generated, and a custom indicator is generated (117). The universal notifier, for example a well-known sound of the direct connect call (115), is thereby preserved, while adding a custom identifier that individual users can readily identify. Variations provide that the custom indicator can be further particularized to a specific call originator, to a specific recipient, to a group, or to a severity phone call such as a local emergency. Group calls with an associated custom indicator can be transmitted in a group call environment.
