Abstract: Embodiments described herein provide systems and methods for securing electrical power and/or data communications between a ground system and an aircraft by monitoring characteristics of the electrical power and/or the data communications from the ground system. The ground system may be prevented from providing electrical power and/or data communications to the aircraft when the characteristics are different than expected.

Abstract: An aircraft system including an aircraft and an electronic instrument on the aircraft, the electronic instrument including a wireless connectivity interface providing wireless communication over at least one communication channel and a display, wherein the display provides a visual indication of an availability of the communication channel.

Abstract: Disclosed is an open ocean farm structure for attachment of macroalgal plants. The farm structure is made up of linear elements connected with nodes to form a three dimensional truss. The linear elements are composed of tubes containing solid rods which are screw connected to the nodes. The ends of the tubes abut the nodes so that screwing the rods into the nodes puts the tubes in compression. The truss structure thus formed is strong and flexible. Because the truss structure is made of tubes having minimal cross-sectional area, the structure is relatively transparent to the forces of wave motion.

Abstract: An electrode structure for an AC matrix-addressed TFEL panel includes top and bottom sets of scanning electrodes, each located in a respective half of the panel, and top and bottom sets of data electrodes extending at right angles to the scanning electrodes where each electrode in the top and bottom set extends for a distance slightly less than halfway across the panel to provide a split screen display. The scanning electrodes are driven by driver amplifiers that simultaneously energize complimentary pairs of the scanning electrodes in the top and bottom halves of the panel driving them in line-by-line fashion. The top and bottom sets of data electrodes are driven simultaneously by top and bottom sets of electrode drivers simultaneously with each scan of the data electrodes. In this way the top and bottom halves of the panel are scanned simultaneously, and the writing of one frame of data is faster. Also, the column electrodes are shorter and therefore require less energy and consume less power per frame.

Abstract: A driving architecture for a matrix addressed TFEL display includes upper and lower data electrode arrays divided by a narrow gap and scanning electrodes arranged in complementary pairs one for each array of data electrodes. The data electrodes are charged at a rate which minimizes the power loss in the resistive component of the data electrode circuitry. The top and bottom data electrode arrays may be driven simultaneously, thereby decreasing the time needed to scan the panel, thus permitting more electrodes and larger screens. The split-screen array provides shorter data electrodes which take less time to charge, thus permitting use of energy-saving techniques which require a slower charging rate.
