    Abstract: Arrangements are presented for adjusting a power level and data rate at an access terminal. The access terminal may include a transmitter module configured to transmit data packets to a gateway. The access terminal may include a receiver module configured to receive control data generated at the gateway. The access terminal may also include a control module. The control module may evaluate the received control data. The control module may increase a transmit power level for data packets to be transmitted from the transmitter module when a first set of conditions is not satisfied. In the first set of conditions, the control data may include a first command. The control module may increase a data rate for data packets to be transmitted from the transmitter module when a second set of conditions is satisfied. In the second set of conditions, the control data may include a second command.

    Abstract: A method for air to ground communication interference mitigation within an aircraft equipped with a multi-beam array antenna includes adjusting a modulation symbol interleaving and/or forward error correction of an aircraft receiver interface in response to detected interference from an interferer. The method further includes reducing a data rate of the aircraft receiver interface when the adjusting of the modulation symbol interleaving and/or forward error correction does not mitigate the detected interference. Another method for interference mitigation may include performing antenna beam-steering away from a geographic (GEO) arc during an aircraft turn. This method further includes reducing an aircraft transmitter transmit power when a signal quality of a forward link is within a predetermined range of a signal quality threshold.

    Abstract: A system and method for determining a signal propagation delay between a transmitter and a receiver, and for adjusting a transmission time based on the propagation delay. A central station inserts a marker into a transmitted signal at a time corresponding to a received timing signal. The MCT receives the signal from the central station and determines a time difference between receipt of the marker and the detection of the time interval event. A transmission by the MCT is adjusted by an amount of time proportional to the time difference.

    Abstract: An apparatus includes an azimuth adjuster coupled between a motor and a directional antenna. Motor rotation causes the azimuth adjuster to rotate the antenna about an azimuthal axis. The motor rotation also causes an elevation adjuster to rotate, which causes a screw mechanism to modify an elevation angle by pivoting the antenna about an elevational axis. To aim the directional antenna, a body-direction vector of a movable body with the antenna attached thereto is determined. Based on an elevational relationship between the body-direction vector and a satellite-direction vector, the elevation adjuster modifies the elevation angle of the antenna by rotating the motor to achieve full-turn amounts to pivot the antenna. The azimuth adjuster modifies an azimuth angle of the antenna based on an azimuthal relationship between the body-direction vector and the satellite-direction vector by rotating the motor to achieve partial-turn amounts of the antenna.

    Abstract: An integrated optical auto focus and zooming system is provided, which includes a first optical lens, a first hollow casing, a second hollow casing, a plurality of piezoelectric elements. The first optical lens is placed in the first hollow casing, the first hollow casing and the second hollow casing are screwed with each other, and the plurality of piezoelectric elements are attached either on the first hollow casing or the second hollow casing. Upon the excitation of mechanical vibrations by the plurality of piezoelectric elements, a traveling wave is generated on the attached casing, so as to drive the other casing to rotate and then to move axially. Additional lens groups and casings can be added in the same way so to achieve multiple relative motions between lens groups and image sensor, and thus achieving the objectives of focusing and zooming. The present invention integrates the motor into the lens and hence eliminates the transmission mechanism, leading to simple structure, high efficiency, and multiple advantages in size, cost, and efficiency, etc., and thus can be very useful.
