Abstract: Novel addressing schemes for controlling electronically addressable displays include a scheme for rear-addressing displays, which allows for in-plane switching of the display material. Other schemes include a rear-addressing scheme which uses a retroreflecting surface to enable greater viewing angle and contrast. Another scheme includes an electrode structure that facilitates manufacture and control of a color display. Another electrode structure facilitates addressing a display using an electrostatic stylus. Methods of using the disclosed electrode structures are also disclosed. Another scheme includes devices combining display materials with silicon transistor addressing structures.

Abstract: The present invention is generally directed to optical signal devices that monitor the quality of an optical signal in a wavelength division multiplexing system by evaluating the information in the different wavelength channels.
Abstract: This invention relates to a bioprocess engineering solution for a product removal process for use in a biofermentation. The invention discloses a process for withdrawing an aliquot of broth from a biofermentation vessel during at least a portion of the biofermentation, removing biocatalyst and water, chromatographically separating biofermentation products from the withdrawn broth using water as an eluent, and returning the remaining components of the broth back to the biofermentation vessel. Process chromatography permits highly selective separation of the target molecule, preventing feedback inhibition of the biofermentation.
