  • Nonradioactive ionization source driver
    Patent number: 9111738
    Abstract: System and method for operating an ionizer using a combination of amplitude modulation and pulse width modulation to control the plasma temperature and the type of ions needed for analytic equipment.

  • STIMULATED VOC CHARACTERIZATION
    Publication number: 20130066349
    Abstract: An electronic odor sensor is used in conjunction with a surgical tool, for example when wounds are cleansed to remove dead tissue and exudates, known clinically as debridement. The surgical tool will atomize substrate tissues and thereby mechanically generate vapors that can be sensed. Abrasion will likewise atomize substrate tissues liberating odors. Air near the surgical tool is collected and fed into the electronic odor sensor. The odor is analyzed by the sensor and a signal fed back based on the analysis.

  • Catalyst for carbon nanotube growth
    Patent number: 8003165
    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.

  • Triode assembly for carbon cold cathode
    Patent number: 6580211
    Abstract: 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.
