Abstract: In some examples, an oscillatory pumping system comprises: one or more active piston, a fluid, and two motors. The one or more active piston is disposed in a channel fluidically coupling two fluid chambers. The passive piston has a frequency response operable to counteract a vibratory displacement. The fluid is disposed in the channel and the two fluid chambers. The two motors couple to the one or more active piston. The two motors are operable to selectively change the frequency response of the passive piston based on oscillating the one or more active piston.

Abstract: An off-highway recreational vehicle includes side-by-side passenger and driver seats held within a chassis. The seats sit low in the chassis and are covered by a roll-over protection system (ROPS). The vehicle is powered by an engine rearward of the seats that utilizes a continuously variable transmission (CVT) to provide power to the ground engaging members, wherein the CVT is cooled via air captured by a CVT intake body located adjacent the driver-side seat, between the frame and external panels of the utility vehicle.

Abstract: A spinner is described that can provide aerodynamic advantages for vertical takeoff and landing (VTOL) aircraft. The spinner can be shaped with multiple faces divided by chines. The chines can run down the edge of the spinner to fairings that can cover rotor blades and/or couplings between rotor blades and the rotor hubs of the aircraft. During forward flight the rotor blades can be folded down into recesses on the spinner. The spinner and fairings can provide aerodynamic advantages in addition to protection for sensitive components within the rotor and blades apparatus. This improves efficiency and allows the aircraft to fly faster.

Abstract: A safety system for aircraft passenger seats is described. A pallet that can be removably coupled to seats can also be removably coupled to the aircraft floor and one or more brackets, tension fittings, or machined straps that can be coupled to structural beams or components in an aircraft. A keel tension fitting can be attached to a keel beam and then be coupled to the pallet and thereby the seats. By attaching to the keel beam the safety system allows the seating arrangement (pallet and seats) to withstand greater stresses and forces, resulting in increased safety.

Abstract: A method of operating an aircraft includes providing a fuel cell system to power the aircraft, providing an airflow path through the fuel cell system, sensing a change mass air flow rate supplied to a compressor of the fuel cell system, and at least one of adjusting a restriction of airflow entering the airflow path in response to the sensed change in mass air flow rate, adjusting a restriction of airflow exiting the airflow path in response to the sensed change in mass air flow rate, and adjusting an air scoop to gather a different amount of air into the airflow path. A method of operating an aircraft includes sensing a change in ambient pressure supplied to an airflow path and adjusting a restriction of airflow exiting the airflow path in response to a sensed change in ambient pressure.

Abstract: A kiosk for use an unmanned aerial system (UAS) delivery system is disclosed. In one embodiment, the kiosk includes an enclosure comprising at least one vertical wall having a secured entrance therethrough to prevent unauthorized persons from entering the enclosure, wherein an external appearance of the enclosure corresponds to a location of the kiosk; a landing zone for an unmanned aerial vehicle (UAV) of the UAS located within the enclosure, the landing zone comprising infrastructure from which the UAV can take off and on which the UAV can land; sensors for detecting an environment of at least one of the kiosk and the enclosure; and a guidance system for providing signals to the UAV to guide the UAV into the enclosure and onto the landing zone.

Abstract: A vehicle comprises a propulsion assembly that includes a rotor system configured to swivel about a pivot axis and a flight control system in communication with the propulsion assembly. In one embodiment, the pivot axis is fixedly oriented at an angle relative to a lateral axis of the vehicle in a plane defined by a longitudinal axis of the vehicle. The flight control system is configured to activate a particular operational mode of the propulsion assembly, in which the rotor system is configured to swivel about the pivot axis to move a rotor axis of the rotor system from a first gimbal angle to a second gimbal angle. In various embodiments, the gimbal angle is configured to change a center of gravity, or direction of thrust vectors, or attitude of the vehicle. The operational mode may comprise a one engine inoperative (OEI) mode in an example embodiment.

Abstract: In an embodiment, a method for automatically generating object inspections includes generating a preliminary list of inspection directions for an object to be inspected. The method also includes checking a compatibility of the preliminary list of inspection directions with each of a plurality of surfaces of the object. The method also includes creating a master set of direction-surface pairs responsive to the checking. The method also includes selecting candidate inspection points for each direction-surface pair in the master set of direction-surface pairs. The method also includes, responsive to a determination that the plurality of surfaces each have at least one compatible inspection direction indicated in the master set of direction-surface pairs, generating an optimized set of direction-surface pairs using a minimization algorithm. The method also includes returning the optimized set of direction-surface pairs and corresponding inspection points.
