An accessory for use with an existing portable electronic device has a housing that removably couples to a housing of the existing portable electronic device such that the accessory and portable electronic device function and can be portably carried as a single unit. A tunable FM radio receiver in the housing receives an FM broadcast signal and produces a broadcast audio output. A connector on the housing electrically connects the broadcast audio output to a corresponding connector on the device. Application software residing on the device utilizes an internet connection of the device to download digital content related to the broadcast audio output and display the digital content on a display of the device.

A transmitting accessory couples with a portable electronic device such that audio signals or data from the device can be digitally transmitted to a remote receiver. The accessory includes an input port for receiving audio data from the portable electronic device. A digital transmitter transmits digital data corresponding to the audio signals or data from the portable electronic device to the remote digital receiver. If the audio signal is an analog signal, the accessory uses encoding circuitry to digitally encode the analog audio signal for transmission. The audio signal may be encoded into an HD radio format for reception by an HD radio receiver. The user inputs of the portable electronic device can preferably be used to control functions of the accessory and the device's display to display the selected transmission frequency or channel.

A media content monitoring system uses a rack adapted to receive multiple carrier boards to improve the system's ability to be configured to specific applications. Each carrier board contains tuner modules for receiving AM/FM broadcasts, satellite radio broadcasts, TV audio broadcasts, HD, IBOC, DAB and DRM digital radio broadcasts, etc. The tuner modules produce a USB output that is combined by a USB hub on the carrier boards into a single USB output. The carrier board outputs are in turn combined by a rack based USB hub into single USB output that is provided to a host computer. The host computer includes content identification software that automatically identifies selected media content received by the tuner modules and stores the selected content in a database. The host computer can send control codes to the tuner modules to alter their reception parameters.

A connector uses complimentary magnetic arrays and mating surfaces on its plug and receptacle to facilitate connection and disconnection of the connector. The plug includes a magnetic array wherein the polarity of the magnets facing the receptacle when the plug and receptacle are connected is selected such that they can only be mated with a complimentary magnetic array on the receptacle when the plug has a desired orientation with respect to the receptacle. The plug and receptacle also have mechanical mating surfaces on their circumference that are shaped such that the plug and the receptacle can only be connected with the desired orientation. The plug can be separated from the receptacle by rotating the plug with respect to the receptacle such that the mechanical mating surfaces break the magnetic connection between the complimentary magnetic arrays.
