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.

Abstract: Various methods and systems are provided for performing nasal high flow therapy. In one example, a method for respiratory support includes: delivering an air and oxygen mixture for nasal high flow therapy to a patient at a flow setting, the flow setting determined based on a peak inspiratory flow obtained during a previous, spontaneous breathing mode during mechanical ventilation of the patient. The flow setting may be a flow rate of a heated and humidified mixture of air and oxygen delivered via a high flow nasal cannula.

Abstract: Multi-function waveforms possessing simultaneous radar and communication capabilities provide the means with which to efficiently combat congestion of the spectrum. Here a joint coding/spatial diversity radar/communication waveform design approach is introduced for use with digital antenna arrays. The proposed approach combines the recently developed phase-attached radar/communication (PARC) approach with the far-field radiated emission design (FFRED) formulation to realize the transmission of multiple independent data streams in arbitrary spatial directions concurrently with active radar sensing that is minimally impacted. The resulting physical signals emitted from the elements of the multiple-input multiple-output (MIMO) array have a desirable structure that is constant-modulus and have improved spectral containment relative to the original FFRED formulation.

Abstract: A stator comprises multiple, stacked laminations, which collectively define a core having a number of posts arranged circumferentially about the core. Each post extends into two prongs defining a first slot between the prongs. The spacing between each posts and its two prongs defines a second slot having a radially inner and outer slot. The outer slot geometry has an increasing width extending radially outward from the radially inner end, and transitioning to a decreasing width extending to the radially outer end.

Abstract: A hydraulic system (e.g., of an aircraft or other vehicle) includes a pump, a pressure line coupled to the pump and configured to distribute pressurized hydraulic fluid, and a return line configured to return hydraulic fluid to a reservoir. The hydraulic system also includes an auxiliary leakage valve coupled to the pressure line, to the return line, and to an actuator. The auxiliary leakage valve is configured to receive a control signal and, based on the control signal, selectively open a restricted fluid path. The restricted fluid path couples the pressure line to the return line to allow a restricted amount of the hydraulic fluid to flow from the pressure line to the return line.

The patient transfer device includes an inspiratory port and an expiratory port which are configured to pneumatically connect to the host. An inspiratory connection is pneumatically connected to the inspiratory port and an expiratory connection is pneumatically connected to the expiratory port.

The inspiratory valve and the expiratory valve are operable between first configurations that permit flow there though and second configurations that occlude flow through the valves. The inspiratory valve and the expiratory valve are configured to operate in the second configuration when the patient transfer device is disconnected from the at least one host device.
