| 20090075611 | TUNER THAT CONDUCTS CHANNEL SEARCH, AND DIVERSITY RECEPTION SYSTEM INCLUDING SAID TUNER - A tuner includes a first mixer circuit multiplying a first radio signal by a first local oscillation signal corresponding to a selected channel to generate a first baseband signal in a normal mode, and multiplying the first radio signal by a first local oscillation signal corresponding to a channel that is a target of search to generate a first baseband signal in a channel search mode, a second mixer circuit multiplying a second radio signal by a second local oscillation signal corresponding to the selected channel to generate a second baseband signal in the normal mode and the channel search mode, and a combining circuit combining a demodulation signal of the first baseband signal and a demodulation signal of the second baseband signal for output in the normal mode, and to output a demodulation signal of the second baseband signal in the channel search mode. | 03-19-2009 |
| 20110136454 | Method Of Determining Station Status Of Non-Audible Tuner In Dual-Tuner System - A system and method of visually providing the current status of selected frequencies of particular interest to the user of an entertainment system and in particular, of a vehicle entertainment system. | 06-09-2011 |
| 20120108191 | Controlling Power Consumption In A Radio Tuner - According to one aspect of the present invention, a controller is coupled to at least first and second signal processors (at least one of which includes analog demodulation circuitry and another of which includes digital demodulation circuitry). The controller may operate to disable the first signal processor responsive to a control signal that indicates that a second signal (corresponding to a demodulator output) is available from the second signal processor. | 05-03-2012 |
| 20120238228 | Radio Transmitter and Radio Receiver with Channel Condition Assessment - FM radio transmitter is being widely used in portable devices as a convenient way to output audio contents to ubiquitously available FM radio receivers in cars or homes. However, the signal from the FM radio transmitter may be interfering with the signal being broadcast by an FM radio station. A scan system is incorporated into the FM radio transmitter to quickly and reliably identify a vacant channel for the FM radio transmitter to use. The scan system measures on-channel and out-of-channel signal quality and selects a best channel for transmission based on the measured on-channel and out-of-channel signal quality. The scan system is also incorporated into an FM radio receiver to quickly and reliably tune to a valid channel. The scan system selects the valid channel based on the measured on-channel and out-of-channel signal quality. | 09-20-2012 |
| 20120264385 | DYNAMIC ALTERNATIVE FREQUENCY CHANNEL SWITCHING IN WIRELESS TERMINAL - Provided is a device and method for providing an Alternative Frequency (AF) in a wireless terminal, by which an AF channel service suitable for a user environment can be provided. To this end, the device includes a radio broadcast receiver for receiving a radio broadcast signal, and a controller for attempting an AF channel switch after an elapse of a re-try wait time which is set according to a number of recent AF channel switch failures. The controller may detect the user environment as a walking state or a driving state. If a driving state is detected, the AF channel switch is attempted immediately when receive signal quality is below a threshold, regardless of the number of recent AF channel failures. If a walking state is detected, the AF channel switch is attempted after the elapse of the wait time. | 10-18-2012 |
| 20140194079 | INCREASING EFFICIENCY OF A RADIO RECEIVER WITH AN ADAPTIVE TUNER - A mobile radio receiver for a vehicle includes a tuner front-end section, a location data port for receiving tuner location data, a sensor port for receiving sensor signal measurement data from at least one vehicle sensor, a tuner front-end section parameter server port for sending the tuner location data, the sensor signal measurement data for receiving a set of tuner front-end section parameter data, and a data processing unit. The data processing unit is operably connected to the tuner front-end section, the location data port, the sensor port, and the tuner front-end section parameter server port. The mobile radio receiver provides an operational mode, a checking mode, a tuner parameter retrieval mode, and a tuner parameter application mode. | 07-10-2014 |
| 20150126143 | Method and Apparatus for Vehicle Radio Station Privacy Mode Control - A system includes a processor configured to receive a request to enable a privacy screen. The processor is further configured to receive a privacy screen engage trigger. Also, the processor is configured to change a current radio station to a predefined station, upon receipt of the engage trigger when a privacy screen is enabled. | 05-07-2015 |
