  • Patent number: 9917605
    Abstract: A method is provided that comprises tuning a radio system to a frequency band that contains a locally-broadcast terrestrial radio signal. The locally-broadcast terrestrial radio signal comprising a main signal component and a side data component is thereby received. In response to receiving the locally-broadcast terrestrial radio signal a determination is made as to a permissible time for processing the side data component using a time slot schedule. The side data component is processed at the permissible time. A message corresponding to the side data component is outputted to an output device. In some instances, the side data component includes the message. In other instances, the method further includes searching a message lookup list using a code included in the side data component. When a stored code is found that matches the code, the message corresponding to the matching stored code is outputted.

    Abstract: A method of operating a radio in a vehicle includes tuning the radio to a first radio source. Information identifying the first radio source is transmitted from the vehicle to a remote processor. The processor monitors broadcast content of the first radio source on a web site. The processor identifies a second radio source having broadcast content matching the broadcast content of the first radio source. Information identifying the second radio source is transmitted from the processor to the vehicle. When a quality of a broadcast signal from the first radio source received at the vehicle falls below a threshold quality level, tuning of the radio is switched from the first radio source to the second radio source.

  • Patent number: 9608454
    Abstract: A method and a system for self-regulating wireless power transmitted to a wireless power receiver (WPR) are provided. An auto-tuning network is operably coupled within the WPR. The auto-tuning network includes an impedance network that dynamically increases, decreases, or maintains an amount of the received wirelessly transmitted power by detecting changes in a rectifier load disposed in the WPR and/or in a rectifier output voltage in the WPR. The auto-tuning network self-regulates the wireless power received from a wireless power transmitter (WPT) obviating the need for conventional communication messages. The WPT is hence free from a modulator/demodulator block and an out-of-band communication block and operates over a limited operating range to enable a simpler design for passing electromagnetic compliance regulations.

    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.

  • Patent number: 8355684
    Abstract: A channel determination apparatus and method for a broadcast receiver are provided. The method includes estimating, when the broadcast receiver operates in a sleep state over a preset time period, inter-modulation distortion interference of a plurality of channels by scanning the channels, and receiving, when the sleep state is transitioned to an active state, broadcast data on a channel having the least inter-modulation distortion interference. Accordingly, the inter-modulation distortion interference of individual channels is taken into account to select an optimum channel, thereby resulting in improvement of channel determination accuracy.

  • Patent number: 8351868
    Abstract: A portable communication device includes a status indictor in the form of a single multicolor generating LED. The single LED indicates radio channel and battery status. The LED is responsive to a menu button press to indicate a current channel by color. Channel change is indicated by changing to another color. The LED is also responsive to a power button on the portable communication device to generate predetermined colors associated with battery status. The use of a single LED eliminates the need for knobs or a display as part of the status indicator of the portable communication device.

  • Patent number: 8335503
    Abstract: In an idle state transition from a macro mobile network to a femtocell, a mobile station looks for the femtocell to operate in a frequency band typically assigned to a macro network. For normal macro network operations, mobile stations look for base stations operating on various channels, e.g. based on hashing of respective mobile station identifiers. Femtocells generate a pilot beacon on a carrier frequency to enable mobile station acquisition, e.g. to redirect a mobile station to the operating frequency of the femtocell. To avoid the need to continually cycle or hop through all possible macro assigned carrier frequencies, pilot beacon transmissions of a particular femtocell are prioritized to correspond to the mobile station(s) expected to utilize that femtocell, e.g. by using existing network information, provisioning device information or self learning/calculating information regarding the carrier most likely to be used by any particular mobile station expected to use the femtocell.

  • Patent number: 8320861
    Abstract: A channel prediction system (100) is provided with an estimation error calculator (130) which calculates an estimation error value representing the difference between a channel estimation value and a channel characteristic, and a prediction error calculator (140) for calculating a prediction error value indicating the difference between the channel prediction value calculated by a channel prediction unit (120) and a channel characteristic. The channel prediction unit (120) uses the channel prediction with priority over using the channel estimation value to calculate the channel prediction value corresponding to a future time when the estimation error value exceeds the prediction error value.

  • Patent number: 8265625
    Abstract: Systems and methods for network entry management are provided. The system includes a base station and a mobile station. The base station broadcasts synchronization channels (SCH) on multiple carriers, where the SCH may be hierarchical synchronization channel composed of primary synchronization channel (P-SCH) and secondary synchronization channel (S-SCH) which are used for timing, frequency synchronization, cell identification, etc. The carriers include at least a first carrier including at least one P-SCH and do not include a S-SCH. The mobile station scans the first carrier, and checks whether a P-SCH is broadcasted on the first carrier. If a P-SCH is broadcasted on the first carrier, the mobile station checks whether an S-SCH is broadcasted on the first carrier. If no S-SCH is broadcasted on the first carrier, the mobile station scans for a second carrier broadcasted by the base station.
