Organic electrophosphorescence device having interfacial layers

Patent Choulis, Stelios A [San Jose, CA]; Mathai, Mathew [Santa Clara, CA]; Choong, Vi-En [San Jose, CA]; ...

Techniques are described for forming an organic light emitting diode device with improved device efficiency. Materials having at least one energy level that is similar to those of a phosphorescent light emitting material in the diode are incorporated into the device to directly inject holes or electrons to the light emitting material.

Method and apparatus for enhanced evanescent fluorescence and color filtering using a high refractive index thin film coating

Patent Kao, Hung Pin [2124 Promontory Cir., San Ramon, CA 94583]; Schoeniger, Joseph [126 Echo Ave., Oakland, CA 94611]; Yang, Nancy [72 Bacon Ct., Lafayette, CA 94549]

A technique for increasing the excitation and collection of evanescent fluorescence radiation emanating from a fiber optic sensor having a high refractive index (n.sub.r), dielectric thin film coating has been disclosed and described. The invention comprises a clad optical fiber core whose cladding is removed on a distal end, the distal end coated with a thin, non-porous, titanium dioxide sol-gel coating. It has been shown that such a fiber will exhibit increased fluorescence coupling due in part by 1) increasing the intensity of the evanescent field at the fiber core surface by a constructive interference effect on the propagating light,more »« less

Hyper-filter-fluorescer spectrometer for x-rays above 120 keV

Patent Wang, Ching L [Livermore, CA]

An apparatus utilizing filter-fluorescer combinations is provided to measure short bursts of high fluence x-rays above 120 keV energy, where there are no practical absorption edges available for conventional filter-fluorescer techniques. The absorption edge of the prefilter is chosen to be less than that of the fluorescer, i.e., E.sub.PRF E.sub.F. In this way, the response function is virtually zero between E.sub.PRF and E.sub.F and well defined and enhanced in an energy band of less than 1000 keV above the 120 keV energy.

Method for reducing pressure drop through filters, and filter exhibiting reduced pressure drop

Patent Sappok, Alexander; Wong, Victor

Methods for generating and applying coatings to filters with porous material in order to reduce large pressure drop increases as material accumulates in a filter, as well as the filter exhibiting reduced and/or more uniform pressure drop. The filter can be a diesel particulate trap for removing particulate matter such as soot from the exhaust of a diesel engine. Porous material such as ash is loaded on the surface of the substrate or filter walls, such as by coating, depositing, distributing or layering the porous material along the channel walls of the filter in an amount effective for minimizing ormore »« less
