摘要:
A polarizer is formed with an arrangement of polymer fibers substantially parallel within a polymer matrix. The polymer fibers are formed of at least first and second polymer materials. At least one of the polymer matrix and the first and second polymer materials is birefringent, and provides a birefringent interface with the adjacent material. Light is reflected and/or scattered at the birefringent interfaces with sensitivity to the polarization of the light. In some embodiments, the polymer fibers are formed as composite fibers, having a plurality of scattering polymer fibers disposed within a filler to form the composite fiber. In other embodiments, the polymer fiber is a multilayered polymer fiber. The polymer fibers may be arranged within the polymer matrix as part of a fiber weave.

The present invention relates to a novel in vivo method for creation of a localized immunosuppressive environment in tissue. The method involves the transplanting of pigmented retinal epithelial cells into a mammal thereby producing a localized immunosuppressive environment. The transplanted pigmented retinal epithelial cells may also be used to produce therapeutic proteins or other biologically active molecules that may be useful in treatment of diseases.

An optical film is provided which comprises a disperse phase of polymeric particles disposed within a continuous birefringent matrix. The film is oriented, typically by stretching, in one or more directions. The size and shape of the disperse phase particles, the volume fraction of the disperse phase, the film thickness, and the amount of orientation are chosen to attain a desired degree of diffuse reflection and total transmission of electromagnetic radiation of a desired wavelength in the resulting film.

Preventing the imaging forming process of an electrostatographic reproduction apparatus having a plurality of imaging modules in tandem relative to a receiver transport belt moveable along a transport path from becoming contaminated with fuser release oil. A substantially uniform layer of the pigmented marking particles from the development subsystem of the image forming process is deposited onto the photoconductive member of the image forming process during any non-imaging cycles of the process, including cycle down, non-imaging skip frames, or recovery from a receiver jam. The substantially uniform layer of pigmented marking particles acts as a barrier to block fuser release oil from the photoconductive member and as a vehicle to carry away contaminating fuser release oil.

An electronic kiosk provides differentiated sales-oriented interactive information services to a plurality of different classes of users such as consumers, contractors and salespersons. The kiosk includes a computing system, a first user application and a second user application. The first and second user applications are executable on the computing system and are operable to provide first and second sales-oriented interactive information services to a first group of users and to a second group of users, respectively. At least some of the first and second interactive information services are different from each other. The computing system is further operable to permit only a defined group of user applications including the first user application and the second user application to be executed thereon.

The present invention discloses a filter medium and a method of manufacturing a filter medium. The filter medium is created using a fabric substrate of a woven or non woven material. The substrate is impregnated with a thermosetting resin that is subsequently heat cured thereby encapsulating the fibers of the substrate. Further a rheology modifier may be mixed with the resin before impregnation to control the flow properties of the resin.

Optical devices using reflective polarizers and, in particular, diffusely reflective polarizers are provided. Many of the optical devices utilize the diffusely reflecting and specularly transmitting properties of diffusely reflecting polarizers to enhance their optical characteristics. The optical devices include a lighting system which uses a reflector formed from a diffusely reflecting polarizer attached to a specular reflector. Another optical device is a display apparatus which uses a diffusely reflecting polarizer layer in combination with a turning lens which folds shallow angle light toward a light modulating layer. Other optical devices exploit the depolarizing characteristics of a diffusely reflecting polarizer when reflecting light. Still other optical devices use diffusely reflecting polarizers to recycle light and improve display illumination.

In a bag configuration, a sanitary cover of clear plastic construction material to be placed over a handgrip of a dentist's overhead light that has an imprint, such as an arrow, on a rear bag panel in the middle of unsealed edges that in use bound an opening through which the handgrip is projected into the bag, in which the user is instructed to rub apart the unsealed edges at the observed site of the arrow, and thus neutralizes a static electricity clinging together of the unsealed edges that otherwise would be difficult to separate.
