Systems and methods for controlling a crossing threshold used in determining a rotational speed of a propeller of an aircraft engine. An initial value for the crossing threshold is set. A sensor signal is received that comprises a first series of pulses indicative of passage of position markers about a circumference of a propeller shaft. A detection signal is generated that comprises a second series of pulses indicative of within the first series of pulses that have a zero-crossing transition and a magnitude that exceeds the crossing threshold. The rotational speed of the propeller is determined from the detection signal. The crossing threshold is adjusted as a function of the rotational speed.

A waste bin device of an aircraft lavatory unit is provided. A chute, waste flap, and waste container are formed from a material having fire resistance performance. A fire spreading prevention space that prevents fire from spreading to the outside of a waste bin device main body due to a flame occurring when inserted waste catches fire is formed inside the waste bin device main body at a storing position of the waste container positioned with regard to a lower portion of the chute. A maintaining portion maintains the waste container at a storing position. The maintaining portion includes a first maintaining portion that maintains from a vertical direction a condition where an upper portion of the waste container and lower portion of the chute are aligned, and a second maintaining portion that maintains the condition from a direction orthogonal to the vertical direction, at the storing position.

A system for handling containers in a freight compartment of a vehicle has a stowage device with a frame in which there are formed devices for receiving containers, at least one robot arm, each with a base a handling tool, a guide device mountable on the frame, and a control unit. The robot arm uses the handling tool to receive and move containers to and from the devices. The guide device moves the robot arm along at least one guide axis. On demand, the control unit actuates the robot arm(s) and the guide device such that a container is received from the respective device by the handling tool and is made available at a predetermined transfer position outside the frame, or such that a container is received by the handling tool at the transfer position and inserted into a device.

A pressure bulkhead system comprises a pressure bulkhead adapted to be connected to a fuselage of a vehicle to separate a pressurized cabin space of the vehicle from an unpressurized cabin space of the vehicle, and a peripheral pressure frame to sealingly connect the pressure bulkhead to the vehicle fuselage. The peripheral pressure frame comprises an attachment section sealingly attached to an outer rim portion of a first surface of the pressure bulkhead. The first surface, when the pressure bulkhead system is installed in the vehicle, faces the unpressurized cabin space of the vehicle. A flange section is adapted to be sealingly attached to an inner surface of the vehicle fuselage and extends in a direction facing away from the first surface of the pressure bulkhead. A flexible section interconnects the attachment section and the flange section and is flexible to accommodate cabin pressure acting on the pressure bulkhead.

The subject invention is a design of marine cargo vessel with added mechanical equipment specifically designed to minimize dangerous motions of the vessel induced by high waves while the vessel is being loaded or unloaded from fixed platforms (bottom supported or tension leg) at sea or on inland waters. The vessel uses three means of reduction of such induced motions, which have not before been combined for this purpose. These are a small water plane area multiple hull design, rapid ballasting while loading and unloading, and vertical thrusters.
