摘要:
Systems and techniques for the analysis of gases for medical purposes are described. In one aspect, a system includes a sample collector to collect a physical sample associated with an individual and present a gas sample for analysis, a gas analysis device to analyze the gas sample presented by the sample collector to determine a concentration of one or more non-aqueous gases in the gas sample, a data storage device that includes information reflecting a correlation between concentration of the one or more non-aqueous gases in the gas sample and a disease state, and a data analysis device to determine a medical condition of the individual based on the concentration of one or more non-aqueous gases in the gas sample and the information.

An industrial scale method for patterning nanoparticle emitters for use as cathodes in a display device is disclosed. The low temperature method can be practiced in high volume applications, with good uniformity of the resulting display device. The method steps involve deposition of CNT emitter material over an entire surface of a prefabricated composite structure, and subsequent removal of the CNT emitter material from unwanted portions of the surface using physical methods.

A screen (which may be a display or electronic display) for projection that has embedded in the screen other active display technologies, such as LEDs, LCDs, etc., or the screen itself is a hybrid of translucent surfaces with a low-resolution display. This display will have two faces such that the alphanumeric information appears from left to right on both sides of the projected image.
摘要:
Substantially enhanced field emission properties are achieved by using a process of covering a non-adhesive material (for example, paper, foam sheet, or roller) over the surface of the CNTs, pressing the material using a certain force, and removing the material.

Embossed microstructures within a substrate are used to create narrow and deep holes within that substrate. A carbon nanotube solution or mixture is then deposited over this substrate with the embossed holes. Shaking or vibrating the substrate will then cause the carbon nanotubes to fall into each of the holes in such a way that all of the nanotubes within a hole will be substantially parallel to the long axis of the hole. This structure can then be combined with a gate electrode and an anode to create a field emission display device.

A plurality of field emission device cathodes each generate emission of electrons, which are then controlled and focused using various electrodes to produce an electron beam. Horizontal and vertical deflection techniques, similar to those used within a cathode ray tube, operate to scan the individual electron beams onto portions of a phosphor screen in order to generate images. The use of the plurality of field emission cathodes provides for a flatter screen depth than possible with a typical cathode ray tube.

A triode structure code cathode assembly is produced by depositing a carbon emitter material onto a substrate to form a cathode structure. Then, an insulating layer is deposited onto one side of a mesh foil to form a mesh assembly. This mesh assembly is then mechanically attached to the cathode structure so that the insulating layer on the one side of the mesh assembly is contacting the cathode structure. This entire triode cathode assembly can then be used to produce a field emission display device by including an anode structure.
摘要:
An image projection system comprises an image projector, such as a film or television projector and a projection screen. The projection screen is fabricated of a substantially transparent material, such as glass or plastic. The screen of transparent material has one or more areas or portions formed therein which areas or portions may be made to be translucent upon the application of a stimulus. Once in a translucent condition, the projected image can be received and viewed on the translucent portion.
摘要:
Carbon nanotubes are aligned within a host phase of a material that has molecules that will align under a certain influence. When the host molecules become aligned, they cause the carbon nanotube fibers to also become aligned in the same direction. The film of aligned carbon nanotubes is then cured into a permanent phase, which can then be polished to produce a thin film of commonly aligned carbon nanotube fibers for use within a field emission device.
