Abstract: The disclosure provides a customizable system for modifying voice dimensions. The system comprises a program interface located on an electronic device. The program interface is used to manipulate user input from one or more individuals relating to voice parameters. Instructions are then created by the program interface that allow for one or more individuals to modify the voice dimensions of the one or more individuals by following the instructions. The disclosure further provides a method for modifying an individual's voice dimensions. The method comprises identifying one or more dimensions in an individual's vocal dimensions that are to be modified. On an electronic device, a voice exercise is created by selecting at least one parameter that modifies the one or more dimensions in an individual's voice. Instructions created by the electronic device that are based on the selection of at least one parameter are then followed by the individual.

Abstract: Carbon nanotubes, which in several embodiments are mixed with particles, organic materials, non-organic materials, or solvents, are deposited on a substrate to form a cold cathode. The deposition of the carbon nanotube mixture is performed using an ink jet printing process.

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: An article of manufacture comprises a carbon-containing matrix. The carbon-containing matrix may comprise at least one type of carbon material selected from the group comprising graphite crystalline carbon materials, carbon powder, and artificial graphite powder. In addition, the carbon-containing matrix comprises a plurality of pores. The article of manufacture also comprises a metal component comprising Al, alloys of Al, or combinations thereof. The metal component is disposed in at least a portion of the plurality of pores. Further, the article of manufacture comprises an additive comprising at least Si. At least a portion of the additive is disposed in an interface between the metal component within the pores and the carbon-containing matrix. The additive enhances phonon coupling and propagation at the interface.

Abstract: A method and apparatus for assembly of small structures is disclosed. The present invention discloses electron beams created from one or more nanotips in an array operated in a field emission mode that can be controlled to apply heat to very well defined spots. The multiple electron beams may be generated and deflected and applied to electron beam heating and welding applications.

Abstract: A method for forming cathodes for use in field emission devices using nanoparticles, such as carbon nanotubes (CNTs), is disclosed. The CNT layer comprises the electron emitting material on the surface of the cathode. Using the methods of the present invention, the density of the deposited CNTs may be modulated by forming emitter islands on the surface of the cathode. The size and distribution of the CNT emitter islands serve to optimize the field emission properties of the resulting CNT layer. In one embodiment, the CNT emitter islands are formed using a screen-printing deposition method. The present invention may be practiced without further process steps after deposition which activate or align the carbon nanotubes for field emission.

Abstract: An optoelectronic modulator is based on the concentration of an electron beam from an electron gun by a tapered cavity, which sides are photosensitive and change the electrical conductivity under the illumination of light (electromagnetic radiation). The light modulation causes the corresponding changes in the current transported across the walls of the cavity. The remaining part of the electron current exits the cavity aperture and forms an amplitude-modulated divergent electron beam.

Abstract: 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.

Abstract: 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.
