An optical sensor system is disclosed including a source module, a detection module, and a heating module. The source module includes a source housing unit having a source window member to emit a detection signal through the source window member. The detection module includes a first detection housing unit having a first detection window member spaced apart from the source module. The detection signal received by the detection module corresponds to an amount of volatile organic compounds (VOC) present in a path of the detection signal between the detection module and the source module. The heating module heats the source window member and the detection window member to remove deposit formation of the VOC there from.

A field emission device, which among other things may be used within an ultra-high density storage system, is disclosed. The emitter device includes an emitter electrode, an extractor electrode, and a solid-state field controlled emitter that utilizes a Schottky metal-semiconductor junction or barrier. The Schottky metal-semiconductor barrier is formed on the emitter electrode and electrically couples with the extractor electrode such that when an electric potential is placed between the emitter electrode and the extractor electrode, a field emission of electrons is generated from an exposed surface of the semiconductor layer. Further, the Schottky metal may be selected from typical conducting layers such as platinum, gold, silver, or a conductive semiconductor layer that is able to provide a high electron pool at the barrier. The semiconductor layer placed on the Schottky metal is typically very weakly conductive of n-type and has a wide band gap in order to create conditions conducive to creating induced negative electron affinity at applied fields necessary to provide electron emission. One type of wide band-gap material can be selected from titanium dioxide or titanium nitride or other comparable materials.

An imaging method includes coating a transfer member with an adhesion promoter in a liquid state, changing the adhesion promoter on the transfer member from the liquid state to at least one of a solid state and a gel state, depositing a liquid marking agent on the solidified adhesion promoter corresponding to an image, changing a state of the adhesion promoter from the solid state to the flowable state, and transferring the liquid marking agent and the adhesion promoter in the flowable state from the transfer member to a substrate to form a hard version of the image thereon.

An optical erasable liquid crystal disc memory system is provided which includes a rotating liquid crystal information storage medium confined by two surfaces. Various thin films on the surfaces are used to establish the proper conditions within the liquid crystal medium which, in combination with incident radition and applied voltages, accomplish the read, write, and erase functions. The resulting system provides a locally erasable optical disc memory with high density storage, long-term information stability under a wide range of temperature, and read, write, and erase times compatible with modern high speed computers.

Techniques for protecting imaging access of electronic paper are described herein. For example, an electronic paper device with protected imaging access includes a substrate, an e-paper surface disposed on the substrate, a removable cover to prevent alteration of the e-paper surface when the cover is disposed over the e-paper surface, and a reversible locking mechanism engaging with the cover to secure the cover in place over the e-paper surface. A method for secure writing to e-paper is also provided.

Significantly improving in the contrast ratio of a visual image display using a liquid crystal layer and a fiber optic faceplate with tilted fibers. One preferred embodiment of the visual image display includes a liquid crystal layer, a first polarizer and an optical fiber faceplate with many substantially parallel fibers. Each fiber has an axis which forms an oblique angle with the normal to the front surface of the liquid crystal layer. All the oblique angles are substantially equal to a typical oblique angle. The typical oblique angle is selected along the direction that substantially maximizes the contrast ratio of the display.
