Abstract: A method for adapting a characteristic of an audible signal produced by a portable communication device includes obtaining a measure of the normal conditions in the environment surrounding the device. The method also includes obtaining at least one measure from a sensor on the portable communication device as a response to an audible event, where the measure corresponds to the current condition in the environment surrounding the device. The method further includes adapting a characteristic of the audible signal based on the relationship between the current condition and the normal condition and presenting the audible signal to a user of the portable communication device.

Abstract: A message is communicated from a first short-range transceiver device to other short-range transceiver devices by determining a set of identifiers of other short-range transceiver devices known by the short-range transceiver device to be within direct communication range of the first short-range transceiver device. An outbound served nodes list is created that includes identifiers of other short-range transceiver devices known either to already have encountered the message or to be members of the set of identifiers. The message and the outbound served nodes list are incorporated into an outbound data structure. For each short-range transceiver whose identifier is a member of the set of identifiers, a previously nonexisting communication link is initiated; the outbound data structure is transmitted to the short-range transceiver; and in response to a completed delivery of the outbound data structure, the communication link is terminated.

Abstract: A user is allowed to select an acoustic equalizer setting from among a plurality of predetermined acoustic equalizer settings. Upon receiving an indication of a selection of a given acoustic equalizer setting, a handheld telephony device processes voice call downlink audio, based on the given acoustic equalizer setting and drives an audio output device with the processed audio signal.

Abstract: A carrier frequency is selected to be used to communicate information to a transceiver in a communication system. Selecting includes, on each of one or more carrier frequencies, transmitting a probe message to the transceiver. A frequency offset between any two adjacent ones of the carrier frequencies is at least about 8 MHz. One or more response messages are received from the transceiver, wherein each of the one or more response messages is a response to a received one of the one or more probe messages. The one or more response messages are used to determine which of the one or more carrier frequencies will be used to communicate information to the transceiver. In some embodiments, each of the probe messages includes a training sequence, and information included in the one or more response messages enables selection of one of a number of possible modulation schemes to be used.

Abstract: A radio communication terminal, and a method for adapting audio characteristics of the terminal. The terminal (10) comprises an audio signal output, such as a speaker (14) or a communication interface (15, 19) to an external speaker (16, 17, 21, 22) configured to provide sound to a user. The terminal also includes an audio adaptation unit (1) configured to assign predetermined audio characteristics to an audio signal, responsive to user input (11), such that a selected setting of audio characteristics can be assigned for subsequently provided audio signals. The audio adaptation unit (1) preferably includes one or more filters, which can be configured to amplify or attenuate an audio signal differently at different frequencies, so as to compensate for impaired hearing.

Abstract: The invention relates to an earphone system with usage detection for controlling the routing of sound signals to an earphone or to a host device. The acoustic load on the earphone is detected and determines if the earphone is in a listening position at the ear of a user or not. The routing of the sound signals is based on the listening position of the earphone. If the earphone is in a listening position, the sounds are routed to the earphone, whereas if the earphone is not in a listening position, the sounds are routed to the host device.

Abstract: A mobile radio terminal having a housing with a loud speaker opening and an ear speaker opening and a speaker selection member coupled to and movable relative to the housing. The speaker selection member has a first audio port and a second audio port spaced such that the loud speaker opening is exposed through the first audio port when the speaker selection member is in a first position and the ear speaker opening is exposed through the second audio port when the speaker selection member is in a second position. In a third position, the loud speaker opening may be exposed through the second port or through a third audio port in the housing.

Abstract: A clamshell phone with two movable housing parts and can assume a closed position, in which the sound openings are covered, and an open position, in which the sound openings are exposed. According to the invention the two housing parts, when in the closed position, define, together with the speaker transducer, a closed cavity with a tube connecting the cavity to the ambient air. This arrangement makes it possible for a communications unit to use the speaker transducer both for reproducing the speech from the teleconversation partner with high quality, and for generating a loud alerting signal and also for reproducing the speech from the teleconversation partner with a sound level that is high enough to be perceived by one or more listeners at a distance from the unit. The invention is useful in mobile phones, cordless and wired telephone handsets.

Abstract: A portable media player can play a large number of media files without being required to physically store all of the media files at any given time. In one implementation, the portable media player includes a memory to store a playlist that includes a plurality of entries succinctly representing media files and a media access manager component. The media access manager component receives media files referenced by entries in the playlist over one or more of a plurality of network connections. The media access manager component downloads the media files as they become available over the network connections based on policies preset on the portable media player and policies preset for the media files.
