Abstract: A folding wingtip aircraft includes a wing that includes a primary portion and a wingtip. The folding wingtip aircraft includes a folding wingtip system configured to rotate the wingtip relative to the primary portion. The folding wingtip aircraft also includes a flight control computer. The flight control computer is configured to, in response to a first determination that a wingtip position of the wingtip is not in a folded position when a second determination indicates that a last completed command by the folding wingtip system was a fold command, set error codes for the folding wingtip system. The flight control computer is also configured to change a setting to indicate that the folding wingtip aircraft is grounded based on the error codes.

Abstract: A method includes implementing, via an electronic controller of an aircraft, an extend command received by the electronic controller from a flight control computer to rotate a wingtip of a wing to a flight position. The method includes, in response to a first determination at the electronic controller that rotation of the wingtip stopped before the flight position during implementation of the extend command, sending a first notification signal to the flight control computer from the electronic controller to cause the aircraft to be grounded and to schedule maintenance of the aircraft. The first notification signal includes one or more first error codes. The first notification signal causes the maintenance to include wingtip-to-latch pin drop maintenance responsive to a determination of the electronic controller indicating that a first particular angle of the wingtip relative to a primary portion of the wing is in a latch pin interference range.

In one aspect of the invention there is provided a gauge wheel for use on cultivation equipment comprising a hub member having a central bearing portion for mounting to the cultivation equipment; a peripheral flange portion displaced laterally with respect to the hub member; and a resilient coil member mounted to a surface of the hub member at a proximal end and comprising at least two windings that extend between the hub member and the peripheral flange portion to terminate at a free distal end adjacent the peripheral flange portion; wherein the free distal end of the resilient coil member is constrained to prevent contact of the resilient coil member with the peripheral flange portion.

Abstract: A crash barrier for an aircraft, which includes an array of elementary nets arranged parallel to each other. Each elementary net includes a generally vertical stop structure which extends between a first upper strap and at least one second lower strap. The first and second straps each includes two end portions for attaching to a braking device, wherein the end portions of the one and/or the other of the upper and lower straps includes a loosened intermediate section, that is, which is not tensed and which forms an “overlength.” The barrier includes an additional strap of which the opposite ends are fastened by linking means to the corresponding ends of the loosened intermediate section. The additional strap includes a region in which it is constituted by two distinct and contiguous strands.

Abstract: A system and method for displaying augmented reality information for a real object. A transparent display displays the information for the real object within a field of view, such that the information and the real object are simultaneously viewable by a user. Data-gathering peripheral devices gather data of the field of view, including a camera gathering visual data for tracking the real object. An articulating arm moveably supports and facilitates repositioning the display and redirecting the data-gathering peripheral devices in a particular direction. A security interlock disables the data-gathering peripherals when the articulating arm is moved beyond a pre-established threshold, thereby preventing the data-gathering peripherals from gathering data of a real environment outside of a limit of the field of view as determined by the pre-established threshold. The security interlock may include an adjustable contact switch which adjustably defines the pre-established threshold in at least one direction.

Abstract: Methods and systems are provided to learn and apply a mapping function from data representing concentrations of atomic elements in a geological formation (or other data corresponding thereto) to mineral component concentrations in the geological formation (and/or from mineral component concentrations to reconstructed elemental concentrations in the geological formation).

The output of the mapping function can be used to determine estimates of one or more formation properties, such as formation matrix density, formation porosity, matrix Sigma, formation saturation, other formation property, or combinations thereof.
