20140245278 | AUTOMOTIVE COMPONENT SELF UPDATE VIA SOFTWARE VERSION CONTROL - A method of updating software files in a motor vehicle includes comparing version identifiers of software files located externally to the vehicle to version identifiers of corresponding software files located within the vehicle. Ones of the software files located within the vehicle that have earlier versions than the corresponding software files located externally to the vehicle are identified. Only the identified ones of the software files located within the vehicle that have earlier versions than the corresponding software files located externally to the vehicle are replaced. The identified ones of the software files located within the vehicle are replaced with the corresponding software files located externally to the vehicle. | 08-28-2014 |
20140213175 | METHOD AND SYSTEM FOR ACHIEVING CONTINUED LISTENING EXPERIENCE FOR CAR RADIO HEAD UNIT - 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. | 07-31-2014 |
20140169589 | AMPLIFIER APPARATUS WITH CONTROLLED NEGATIVE OUTPUT IMPEDANCE - An audio amplifier apparatus includes an audio amplifier which receives a single audio signal and produces a plus phase audio signal and a minus phase audio signal, both dependent upon the single audio signal. The plus phase audio signal and minus phase audio signal are received by first and second inputs of a speaker, respectively. A current sensing circuit senses a level of current received by the first or second inputs of the speaker and outputs a current sensing signal dependent upon the sensed level of current. An amplifying circuit receives and amplifies the current sensing signal. A mixer circuit receives the amplified current sensing signal and an audio drive signal and produces the single audio signal dependent upon the amplified current sensing signal and the audio drive signal. The single audio signal is produced at a node in-between two resistors. | 06-19-2014 |
