Abstract: A cartridge for an aerosol provision system comprising the cartridge and a control unit. The cartridge comprises: an air channel extending from an air inlet for the cartridge to an outlet via an aerosol generation region; a heating element for heating aerosolizable material, such as liquid, from a reservoir to generate aerosol in the aerosol generation region; and a valve located in the air channel upstream of the aerosol generating region. The cartridge is configured such that air passing through the air channel is configured to pass from the air inlet, past the air valve, into the aerosol generating region, and then out from the aerosol outlet.

Abstract: Aspects of the present disclosure describe systems, methods, and structures that enable a compact, UHV ion trap system that can operate at temperatures above cryogenic temperatures. Ion trap systems in accordance with the present disclosure are surface treated and sealed while held in a UHV environment, where disparate components are joined via UHV seals, such as weld joints, compressible metal flanges, and UHV-compatible solder joints. As a result, no cryogenic pump is required, thereby enabling an extremely small-volume system.

Abstract: A cartridge for an aerosol provision system. The cartridge includes an air channel extending from an air inlet to an outlet via an aerosol generation region. The cartridge also includes a heating element for heating liquid from a reservoir to generate aerosol and an aerosol outlet tube. The aerosol outlet tube has a first end and a second end. The first end is proximate to the aerosol generation region and second end is configured to fit inside an air channel seal. The aerosol outlet tube tapers inwardly from the first end to the second end such that a cross-sectional area of the second end is less than a cross-sectional area of the first end. The cartridge is configured such that air passes from the air inlet, into the aerosol generating region, through the aerosol outlet tube, past the air channel seal and then out from the outlet.

Abstract: A cartridge for an aerosol provision system can include the cartridge and a control unit, and the system can include a vaporizer for vaporizing an aerosolizable material. The cartridge can include an air channel extending from an air inlet for the cartridge to an outlet via an aerosol generation region, and a reservoir for containing aerosolizable material for aerosolizing. The cartridge can further include an aerosolizable material level observation means for allowing a user to observe a level of aerosolizable material inside the reservoir. The aerosolizable-material-level observation means can include at least one contoured surface located on a surface of the cartridge to improve the visibility of the aerosolizable material level inside the reservoir due to the interaction of light with the contoured surface.

Abstract: A cartridge for an aerosol provision system that includes the cartridge and a control unit, wherein the system comprises a vaporizer for vaporizing an aerosolizable material. The cartridge can include an air channel extending from an air inlet for the cartridge to an outlet via an aerosol generation region, and a reservoir for containing aerosolizable material for aerosolizing. The cartridge can further include an aerosolizable material level observation means for allowing a user to observe a level of aerosolizable material inside the reservoir. The aerosolizable material level observation means can include a portion of the cartridge, which can include a window for viewing into the reservoir. The portion of the cartridge may be located on a first side surface and a second side surface of the cartridge, and/or might be located on a different surface of the cartridge.

Abstract: An inflatable pillow system includes a pillow formed of an upper and lower bladder that may be independently inflated and deflated. A controller includes an air mover, a valve assembly, and a control box. The valve assembly includes an air line to the upper bladder, and an air line to the lower bladder. Each of an upper air line valve and a lower air line valve is urged into a closed position by an valve spring, and is movable into an open position by an valve servo. The air line valves may include hollow valve plungers, so that the valve springs extend into the plungers. The control box has an input for inflating and deflating the upper bladder, and an input for inflating and deflating the lower bladder.

Abstract: A transmission arrangement including a torque converter, a first shaft fixed to rotate with a turbine of the torque converter about an axis, a second shaft fixed to rotate with a casing of the torque converter about said axis, a gear mounted on the first shaft and being fixed to rotate with the first shaft and a clutch selectively engageable to cause the first shaft to be fixed to rotate with the second shaft and being selectively disengageable to allow the first shaft to rotate relative to the second shaft, the clutch being rotatable about said axis.
