摘要:
A goggle based light-weight VOG system includes an integral calibration laser and at least one digital camera connected to and powered by a laptop computer through a firewire connection. The digital camera may digitally center the pupil in both the X and Y directions. A calibration mechanism may be incorporated onto the goggle base. An EOG system may also be incorporated directly into the goggle. The VOG system may track and record 3-D movement of the eye, track pupil dilation, head position and goggle slippage. An animated eye display provides data in a more meaningful fashion. The VOG system is a modular design whereby the same goggle frame or base is used to build a variety of digital camera VOG systems.

The invention provides a composition and method for reducing molecular defects in metastable tissue systems. Molecular defects represent spaces or vacancies in the structural order of the metastable system. The effect of molecular defects can be minimized such that the pre-defect order is preserved through the use of structure makers. These structure makers will then occupy the space or vacancy of the molecular defect, preserving the pre-defect order of the system. Lithium ions are a preferred structure maker.

A fiber containing a bound active material, such as. a metal oxide, under 20 microns in diameter. The inventive fiber is formed through the mixing of the fibers with a cationic or anionic polymer in one tank, the active material with a cationic or anionic polymer in a second tank, the opposite zeta potential of that used with the active material, and then mixing the active material/polymer and fiber/polymer blends together.
摘要:
A hydrodynamic sealing assembly including a first component having first and second walls and a peripheral wall defining a seal groove, a second component having a rotatable surface relative to said first component, and a hydrodynamic seal comprising a seal body of generally ring-shaped configuration having a circumference. The seal body includes hydrodynamic and static sealing lips each having a cross-sectional area that substantially vary in time with each other about the circumference. In an uninstalled condition, the seal body has a length defined between first and second seal body ends which varies in time with the hydrodynamic sealing lip cross-sectional area. The first and second ends generally face the first and second walls, respectively. In the uninstalled condition, the first end is angulated relative to the first wall and the second end is angulated relative to the second wall. The seal body has a twist-limiting surface adjacent the static sealing lip. In the uninstalled condition, the twist-limiting surface is angulated relative to the peripheral wall and varies along the circumference. A seal body discontinuity and a first component discontinuity mate to prevent rotation of the seal body relative to the first component.

The present invention relates to an effective and rapid method and apparatus for sintering filter blocks having a polymeric binder. The method employs direct contact heat transfer by gas molecule to powder particle, as opposed to conduction heat transfer from an external heating source, using commercially available sintered porous metal sheets and cylinders to form the mold and confine the powder, while allowing heated gas to pass uniformly through the mixture.

摘要:
Improved single-phase aerosol spray air sanitizers and deodorizers are disclosed. The preferred active ingredient for the air sanitization is a high concentration of triethylene glycol (TEG), in a single-phase aerosol formulation made possible by the use of dimethyl ether (DME) as a propellant. The combination of TEG and DME enables high concentrations of TEG to be utilized in a single-phase aerosol formulation, without requiring the use of ethanol or water as co-solvents. The formulation is useful for sanitizing air and removing bacteria and other malodorants from the air as well achieving higher bacteria kill rates than existing air sanitization formulations due to the high concentrations of TEG. Because the high concentration TEG aerosol formulation is a single-phase formulation, it can be utilized in automated spray or dispensing systems and do not require shaking or agitation prior to use. Disclosed formulations leave little or no visible residue on hard surfaces when dispensed into the air of a room.
摘要:
A pressure gradient rotary sealing system is described with an additional configuration which uses and externally mounted pressure-reducing piston with a differential area to create a pressure differential across the system to reduce the pressure×velocity (PV) value to extend seal system life and provide early indication of impending seal failure. This invention is another embodiment of this previous invention offering using a separate externally mounted pressure reducing piston therefore the main body of the wash-pipe top-nut is lighter weight, the system has more fluid capacity, is simpler to assemble, operate and monitor and has a longer service life than previous configurations.
