Abstract: A rotatable nacelle includes an engine inlet configured to receive air and an inlet air management system (IAMS). The IAMS includes a primary inlet configured to selectively allow air to flow into a duct associated with the engine air inlet via the primary inlet and a secondary inlet configured to selectively allow air to flow into the duct associated with the engine air inlet via the secondary inlet. The secondary inlet is configured to receive an air filter.

Abstract: A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

Abstract: A vehicle axle, for example for a driven; undriven, steering or trailer system, comprises a member (1) formed as a hollow monocoque structure which includes at least one integral location (3, 20, 23) formed in the structure as a low stress area adapted to receive an attachment (24, 31, 34) thereto for use of the axle in a vehicle. The monocoque structure may be rigid, or substantially so, or it may include one or more compliant portions. It distributes throughout the member stresses to which the member is subjected when the axle is use in a vehicle and parts of the structure may be specifically shaped to suit the particular stresses to which they will be subjected when in use. In one embodiment the monocoque structure includes an axle beam part of a hollow lobed cross-section which gives roll compliance without necessarily having to add resilient components. In this embodiment trailing arms (4) are formed as an integral part of the monocoque structure which forms part of a trailing suspension system.
