    Abstract: A vehicle audio/video media system includes an adapter apparatus in electrical communication with an audio/video head unit. The adapter apparatus includes a digital input receiving digital audio/video content from an external source. A digital-to-analog converter is coupled to the digital input and converts the digital audio/video content into analog audio/video content. An output device is coupled to the digital-to-analog converter. The output device transmits the analog audio/video content to the audio/video head unit.

    Abstract: The electroacoustical properties of an electromechanical vibrating device for producing an audible signal are improved by attenuating undesirable frequencies of the audible signal to produce a predominant frequency and by accentuating the predominant frequency. The improvement includes a planar vibration diaphram comprised of a plastic polymer material, a vibrating striking member positioned to strike the vibration diaphram at its center; a bumper comprised of resilient material interposed between the vibrating striking member and the vibration diaphram, and a resonant chamber in spaced relation to the vibration diaphram having a resonant frequency substantially equal to the predominant frequency.

    Abstract: An audio system includes a level controller receiving an input audio signal from an audio medium. The level controller includes a gain adjust module producing an output audio signal based on the input audio signal. A filter arrangement is communicatively coupled to the level controller. The filter arrangement receives the output audio signal and divides the output signal into a plurality of filtered signals. Each of the filtered signals corresponds to a respective frequency band. A multiband dynamics controller is communicatively coupled to the filter arrangement. The multiband dynamics controller receives the filtered signals and applies a respective gain characteristic to each of the filtered signals to thereby produce a plurality of gain adjust signals. The gain adjust signals are combined into a multiband dynamics controller output signal.

    Abstract: There is provided a system and method of providing personalized content to a user based on the user's interests and the user's geographical location. The method includes receiving media files from a portable device associated with the user and generating a user profile based on the media files. The method also includes receiving a geographical location of the user from a global positioning system (GPS) device. The method also includes receiving content from a service provider based on the user profile and the geographical location. The method also includes providing the content to the user through an infotainment interface included in a vehicle. The content delivered to the user may include media files such as music or audio/visual files that correspond with the user profile. The content may also include messages about events near the user's geographical location that correspond with the user profile.
