Abstract: An Emergency Position Indicating Radio Beacon (EPIRB) comprising an integrated wireless receiver, a graphical display device, capability to utilize both internal and external GPS coordinate sources, an infrared background lighting adjustment algorithm, and a multi-LED strobe light array. The receiver provides a return communications path back to the beacon, which is used to acknowledge the receipt of the beacon's outgoing emergency signal by Search and Rescue satellites. The display is used to visually display various operational status information as well as any received messages coming back into the receiver. The GPS receiver system switches between internally derived and/or externally supplied GPS coordinates. The present invention also incorporates an Automatic Background Light Adjustment (ABLA) algorithm to compensate for the maximum range of light intensity encountered by infrared communications LEDs during daytime and nighttime operation.

Abstract: A dual input mobile communication device. The mobile communication device can include a housing having an exterior, the exterior including a first face side and a second face side, the second face side located on an opposite side of the housing from the first face side, a first display disposed on the first face side, a numeric keypad disposed on the first face side, a second display disposed on the second face side, and a text keypad disposed on the second face side. The numeric keypad can be a telephone keypad such as a dual-tone multiple-frequency (DTMF) keypad and text keypad can be a QWERTY keypad, such as a keypad having a layout similar to a typical typewriter-style keyboard. The housing can be a candy bar phone style housing.
