Abstract: A portion of the housing of an air operated leveling device is configured to integrally include an air valve receptacle which receives thereinside a solenoid valve. The housing carries an air fitting and an electrical connector which are interconnected with the solenoid valve receptacle, and, in turn, the solenoid valve. 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 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.

Abstract: The present invention concerns an air spring and jounce shock assembly for use in an automotive vehicle suspension system. The assembly may include a base adapted to be mounted on one of an axle assembly and a suspension component, a top cap adapted to be attached to a vehicle frame, and a diaphragm disposed between and attached to the base and the top cap, with the diaphragm including an inner surface defining a first portion of a compressed air cavity. A jounce shock reaction surface defines a second portion of the compressed air cavity and is included in a one of the top cap and the base.

Abstract: Nanoparticles are coated using thick-film techniques with a catalyst to promote the growth of carbon nanotubes thereon. In one example, alumina nanoparticles are coated with a copper catalyst. Such nanoparticles can be selectively deposited onto a substrate to create a field emission cathode, which can then be utilized within field emission devices.

Abstract: Composition of carbon nanotubes (CNTs) are produced into inks that are dispensable via ink jet deposition processes. The CNT ink is dispensed into wells formed in a cathode structure.

Abstract: This invention relates to a method of fabricating a field emission device (FED) by using a carbon composite film, the composite film providing a field emission layer which consists of fine carbon-metal grains and/or carbon nanotubes, so that (a) a threshold voltage required for emitting electrons from the field emission device can be lowered significantly; (b) a stable electron beam of the field emission display device can be increased; and, (c) emission Uniformity and emission spot density can be greatly improved. The fabrication method involves preparing a metal-carbon composite film on a suitable substrate using an appropriate deposition technique. The carbon composite film is then thermally treated post-deposition, so as to form nano-particles and/or nanotubes in the film. Post-treatment of the composite film may involve annealing or plasma etching using hydrogen or hydrocarbon gas to reduce the electron emission barrier.

Abstract: A hydrogen sensor and/or switch fabricated from an array of nanowires or a nanoparticle thick film composed of metal or metal alloys. The sensor and/or switch demonstrates a wide operating temperature range and shortened response time due to fabrication materials and methods. The nanowires or nanoparticle thick films demonstrate an increase in conductivity in the presence of hydrogen.
