20110306313 | METHOD AND APPARATUS FOR UTILIZING MODULATION BASED AUDIO CORRELATION TECHNIQUE FOR MAINTAINING DYNAMIC FM STATION LIST IN SINGLE TUNER VARIANT AND ASSISTING ALTERNATE FREQUENCY SWITCHING METHODOLOGY IN SINGLE TUNER AND DUAL TUNER VARIANTS - A method of operating a single-tuner radio includes tuning into a first frequency. A pause in a first signal associated with the first frequency is detected. Tuning is switched from the first frequency to a second frequency during the pause. Fieldstrength, multipath, adjacent channel energy, frequency offset and FM modulation for the second frequency are measured. Tuning is switched from the second frequency to the first frequency. Tuning is switched from the first frequency to the second frequency dependent upon the measuring step. | 12-15-2011 |
20120190319 | METHOD AND APPARATUS FOR SENSING INTER-MODULATION TO IMPROVE RADIO PERFORMANCE IN SINGLE AND DUAL TUNER - A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact. | 07-26-2012 |
20130165065 | METHOD AND APPARATUS FOR DYNAMICALLY ADAPTING FM TUNER SENSITIVITY TO A LOCAL ENVIRONMENT FOR A SINGLE-TUNER SYSTEM - A method of operating a single-tuner radio includes tuning into a first frequency. A pause in a first signal associated with the first frequency is detected. Tuning is switched from the first frequency to a second frequency. A signal quality metric for the second frequency is measured. Tuning is switched from the second frequency to the first frequency. | 06-27-2013 |

20150126144 | METHOD AND APPARATUS FOR MODE BALANCE FOR ANALOG FM, DIGITAL RADIO BLEND LOGIC IN AN AUTOMOTIVE ENVIRONMENT - A radio includes a first tuner and a second tuner. A processor compares a first perceivable volume level of a station tuned by the first tuner to at least one second perceivable volume level of at least one background station tuned by the second tuner. The processor enables automatic volume knob changes using a pre-calibrated lookup table that associates a volume step of the volume knob with a difference between the first perceivable volume level and the second perceivable volume level. | 05-07-2015 |
