Abstract: 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.

Abstract: A pen or stylus for use with a touch screen computer. The stylus has a conductive body and a conductive tip. A relay in the stylus is used to selectively electrically connect the conductive stylus body, which is coupled to the hand of the, user, to the conductive tip. A series of the pulses are produced by the stylus that are detected by software on the computer. The detected pulses can be used to differentiate between a finger touch and a stylus touch and to transfer data or commands from the stylus to the touch screen device.

Abstract: An accessory for a portable electronic device having a speaker uses an acoustic wave guide to passively amplify and direct the output of the device's speaker. The accessory has a housing with a docking cavity formed therein. The docking cavity has supportive sidewalls that are adapted to receive and support the portable electronic device in an upright position. A cable access channel is formed in the docking cavity that allows a connector and cable to be coupled to the portable electronic device when the portable electronic device is mounted in the docking cavity. An acoustic waveguide having a spiral shaped acoustic chamber is positioned in the housing such that an entrance to the acoustic waveguide corresponds to a hole in the docking cavity that is positioned to correspond to the location of the speaker of the device when the device is mounted in the docking chamber. The exit of the acoustic chamber corresponds to an exterior opening in a sidewall of the housing and the hole in the docking cavity.
