Abstract: 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.

Abstract: A light exposure system is used to expose an alignment layer formed of anistropically absorbing molecules so as to allow alignment of subsequently applied liquid crystal polymer (LCP) molecules. The light incident on the alignment layer is polarized. When a single polarizer is used, the azimuthal polarization direction varies across the substrate carrying the alignment layer. Various approaches to reducing the azimuthal polarization variation may be adopted, including the introduction of various types of polarization rotation reduction element and in selecting an appropriate tilt angle for the light source. Furthermore, a reflective structure may be inserted between the light source and the alignment layer. Use of the reflective structure increases the total amount of light incident on the alignment layer.

Abstract: A process for making an optical film includes stretching a polyolefin film in a first direction and stretching the polyolefin film in a second direction different than the first direction forming a biaxially stretched polyolefin film. At least a portion of the stretching of the polyolefin film in the second direction occurs simultaneous with the stretching of the polyolefin film in the first direction. The biaxially stretched polyolefin film has a length and a width and substantially non-absorbing and non-scattering for at least one polarization state of visible light. The biaxially stretched polyolefin film has x, y, and z orthogonal indices of refraction where at least two of the orthogonal indices of refraction are not equal, an in-plane retardance being 100 nm or less and an out-of-plane retardance being 50 nm or greater.

Abstract: The invention provides methods for the treatment of abnormal psychiatric states, particularly the negative symptoms of schizophrenia and extrapyramidal side effects (EPS) of antipsychotic drugs. The inventive methods relate to the administration of therapeutic cells (which produce dopamine or dopamine precursors) adhered to support matrices to subjects suffering from the negative symptoms of schizophrenia and/or EPS. The therapeutic cells may be coadministered with cells which protect the therapeutic cells from immune rejection and/or cells which produce neurotrophic factors which improve the viability of the therapeutic cells.
