Abstract: Exemplary embodiments of the present invention relate to a mobile information display system that may be configured by a user to have customized interface screens and to display individualized content. For example, upon starting of the ignition system, the mobile information display system may access a remote server using a radio network interface to download interface screens that have previously been designed by a user. Further, the mobile information display system may download information and content from the remote server, or from other websites, including, for example, navigational information, destination information, calendar and alarm entries, e-mail messages, voice mail messages, personal networking pages, internet phone service, internet audio programs, and internet video programs, among others.

Abstract: An audio system includes an automatic level controller receiving at least one input audio signal from at least one audio medium. The automatic level controller includes a gain adjust module for producing an output audio signal based on the at least one input audio signal. A difference between a maximum sound level and a minimum sound level of the at least one input audio signal is greater than a difference between a maximum sound level and a minimum sound level of the output audio signal. A filter arrangement is communicatively coupled to the automatic 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.

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 interface uses a combination of controls that retain essentially the same function throughout all modes and features and controls that vary based on the active mode or feature. The interface also includes a display. The display can provide text information, graphic information or a combination of text and graphics. The arrangement of the mode controls, the soft controls and the display is designed to facilitate the user's interaction with the system. The system provides some redundant controls so that the user can select the control that is most convenient or intuitive for that user.

Abstract: The interface uses a combination of controls that retain essentially the same function throughout all modes and features and controls that vary based on the active mode or feature. The system uses a common list modifier interface and a common list interface so that the interface is intuitive to the user regardless of the active mode. The interface allows a user to easily select a mode or switch to another mode. In addition, the interface provides some automatic mode switching. The interface also includes a display. The arrangement of the mode controls, the soft controls and the display is designed to facilitate the user's interaction with the system. The system provides some redundant controls so that the user can select the control that is most convenient or intuitive for that user.

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: A piezoelectric transducer and a voltage doubling means are utilized in conjunction with a power supply means, a pulsator means, an amplifier means, and an acoustical loading means to produce an efficient high output audible alarm device. The voltage doubling means and the acoustical loading means enhance the audible output of the alarm device while increasing the overall electroacoustical efficiency of the alarm.

Abstract: A high output smoke and heat detector alarm system comprises a high output audible alarm means which includes a piezoelectric transducer and a voltage doubling means in combination with an improved smoke and heat detector which includes a low voltage power supply source, an ambient temperature detecting means, at least one ionization sensing chamber, a voltage amplitude comparing means, and a low voltage sensing means.
