Abstract: A system for autonomous navigation within an enclosed area is provided. The system can have a remote control station having a route management system operable to determine a flight plan. The system can further have a device configured for unmanned operation having a transceiver operable to receive the flight plan from the remote control station. The device can have a memory operable to store the flight plan and an electromagnetic (EM) map of the enclosed area. The device can have a location determination sensor (LDS) operable to determine a three dimensional position of the device within the enclosed area based on the EM map.

Abstract: The disclosure is related to a system and method for autonomously charging a rechargeable power supply of an Unmanned Aerial System (UAS). The system can have battery power translator (BPT). communicatively coupled to the UAS. The BPT can have an energy source operable to deliver power at a native power level different than a designed power level of the UAS. The BPT can also have a voltage/current translator (VCT) operable to receive energy at the native power level from the energy source, and convert the energy at the native power level to converted energy at the designed power level for use by the UAS. The system can also have a remote charging system (RCS) communicatively coupled to the BPT. The RCS can also have a charging pad having a plurality of configurable terminals, and operable to receive the UAS and deliver recharge energy to the UAS.

Abstract: The present invention relates to a communication device for a personal digital assistant (PDA). The PDA mounts within the communication device and the communication device connects electronically to a serial port on the PDA. Through this single serial port, the communication device provides the user of the PDA with access to multiple communication media, such as a telephone modem, a Global Positioning System engine, a packet radio and a cellular telephone. Data from the PDA is directed to a decoder that routes the data to the appropriate communication medium, while data from the communication media are multiplexed onto the single serial interface of the PDA. The communication device also provides a pass-thru serial interface that allows other external devices to communicate directly with the serial port of the PDA.
