Abstract: An aircraft including a wing with a fixed wing portion and a wing tip device rotatably hingedly attached at a fixed wing portion outboard end. The wing includes a wing fold mechanism configured to actuate the wing tip device to rotate relative to the fixed wing portion to at least three commanded and predetermined wing fold angles and to restrain rotational movement of the wing tip device at each commanded position. A first position corresponds to high-speed flying, a second position to ground-based operations and a third position to low-speed flying. The flying positions rotate the wing tip to a position where upper and lower wing tip surfaces are continuations of the upper and lower surfaces of the fixed wing, with a low-speed incidence angle being less than a high-speed incidence angle. The ground-based position reduces the wing span to the greatest degree of the three positions.

Abstract: A charging device is configured to deliver power to a portable, power-consuming device, having a profile sensor which can detect information relating to the identity of power-consuming device to which the charging device is connected and may also have a communication channel configured to transmit said information to a remote server. In use, data can be collected or aggregated relating to power-consuming devices by connecting the charging device to the portable power-consuming device; sensing, by a profile sensor in the charging device, information relating to the identity of the power-consuming device; and transmitting the information to a remote server over a communication channel. Collected data may, for example, be used to identify when fuel for a charging device may need replenishment.

Abstract: A microvalve assembly (30) is integrated into a printed circuit board (PCB) substrate (31). An aperture (32) in the PCB substrate includes a closure member (33) extending into the aperture. A flexible fluid pipe (38) is disposed between the closure member and a closure edge (37) of the aperture. A displacement member (34) is coupled to the PCB and is configured for thermal actuation to displace the closure member so as to vary the cross-sectional profile of the flexible fluid pipe. The closure member may be a cantilever section of the PCB substrate. Displacement of the closure member to vary the cross-sectional profile of the flexible fluid pipe can occur entirely within the plane of the PCB substrate and movement of the displacement member to displace the closure member can also occur entirely within the plane of the PCB substrate, providing a very low profile of microvalve particularly suited for integration into a fuel cell stack (1).

Abstract: A system for testing an individual for illicit or other substances is described. The system operates in tandem with a mobile device (smartphone) application, which employs a camera of the mobile device to capture and record the self-administered specimen collection process for verification and rule compliance. The system guides the user through the process via on-screen prompts on the mobile device, and includes tracking of the collected specimen from the moment of collection until it is sealed in a tamper-proof container to be mailed for external testing at a lab. A breathalyzer may also be used with the system to test for the presence of alcohol in the user's body, the use of which is also monitored and recorded via the on-board camera of the mobile device for verification.

Abstract: A centralizer comprises two collars that are connected by asymmetric spring bows. The spring bows each comprise two arcs, where the curvature of one arc is inverted with respect to the curvature of the other arc, one being concave and the other convex. The spring bows are in sets that are equidistantly spaced around the circumference of the collars, each set having the same configuration, and the opposite configuration to the spring bows in the other set. Upon insertion into a wellbore, one set of spring bows is therefore compressed before the other set. Upon compression, the deformation of the concave arc leads to mutual deformation of the convex arc, and the spring bows adopt a flatter configuration, enhancing the rotational freedom of the tubular.
