  • Publication number: 20130309986
    Abstract: A system and method provide an enhanced listening experience for a user of a radio receiver or other device that receives broadcast or streamed content having a plurality of program channels. The method and system buffer designated channels at the receiver and, when switching among channels, play back the buffered designated channels during reception from a selected point therein depending on the channel or other criteria. When switching to a different channel during reception, a user is able to hear content in a buffered program channel with music from the start of a song, for example, whereas content in a channel with news, talk radio, or live sports is played back from live reception, even though the content segments are transmitted at different start times relative to their selected times for playback following a channel change. User controls allow navigation among buffered designated channels during reception.

  • Patent number: 8588717
    Abstract: A radio communications device includes a headphone assembly, which includes at least one aural speaker or transducer and a headphone cable functioning as an antenna and providing electrical signals carrying audio information to the at least one aural speaker or transducer. A signal separator coupled to the headphone cable separates the electrical signals carrying audio information transmitted to the headphone cable and radio frequency (RF) signals received from the headphone cable. A radio receiver receives the RF signals from the signal separator and converts the RF signals to electrical signals carrying audio information. A tuner is provided for tuning the headphone cable to a selected operating frequency of the radio receiver. An audio amplifier amplifies electrical signals carrying audio information from the radio receiver to be transmitted through the headphone cable to the at least one aural speaker or transducer.

  • Patent number: 8577316
    Abstract: Mechanically tuned radios and related methods are disclosed that utilize ratiometric time measurements to detect settings for mechanical adjustment mechanisms. The radio systems and methods disclosed make a first time measurement associated with a mechanically adjusted circuit, make a second time measurement associated with the mechanically adjusted circuit, determine a setting for the mechanical adjustment mechanism based upon a ratio associated with the first and second time measurements, and utilize the setting to select a tuning frequency for signals received by the radio. More generally, ratiometric time measurements can be used to determine a setting for a mechanical adjustment mechanism for a mechanically adjusted circuit, and this setting can be used to at least part control a desired operational feature of a device.

  • Patent number: 8571466
    Abstract: Systems and methods are provided for providing recommended radio stations to a user. In particular, an electronic device can compare media from a locally stored or accessed media library with media items provided as part of radio streams received by the device. The electronic device can identify the radio streams having the most media items overlapping with the local library, and recommend those streams as being most likely to be of interest to the user. The electronic device can further access a remote database of a large number of users' libraries, and receive recommendations based on the media items common to the user's library, other users' libraries, and radio broadcasts. This approach allows the electronic device to provide recommendations without requiring any monitoring of the user's listening habits or receiving preference information from the user.
