Abstract: A series arranged air compressors system includes a first air compressor and a second air compressor pneumatically connected in series in an open, closed or partially closed state of operation. The output of the second air compressor is used as a source of compressed air for an air suspension system of a motor vehicle and/or to pressurize air inflatable articles. Flow of compressed air is selectively controlled by an electronic control circuit via at least one air flow control block, and the system may further include one or more air reservoirs.

The solenoid valve communicates with the air fitting and the interior of the housing to regulate pressure inside the housing in response to electrical signals sent to the electrical connector.

Abstract: A binder material, inorganic polymer, is used to formulate carbon nanotube pastes. This material can be cured at 200° C. and has a thermal-stability up to 500° C. Low-out gassing of this binder material makes it a good candidate for long life field emission devices. Due to better adhesion with this binder material, a strong adhesive peelable polymer from liquid form can be applied on the CNT cathode to achieve a uniform activation with even contact and pressure on the surface. The peelable polymer films may be used both as an activation layer and a mask layer to fabricate high-resolution patterned carbon nanotube cathodes for field emission devices using lithographic processes.
