  • Patent number: 6551526
    Abstract: In color printing, and in the fine arts, cholesteric liquid crystal (CLC) color inks are known to possess much higher color saturation and brightness than conventional pigment and dyed based inks. However, prior art CLC ink formulations are inconvenient because in the liquid phase they have to be confined in cells, and in the solid phase, they have to be applied at high temperature, and have to be aligned by some means to produce the optimum color. This invention solves the problem encountered in the CLC prior art, by making pre-aligned CLC platelets or flakes of appropriate thickness and size and mixing them in appropriate host fluids producing a novel CLC ink which can be applied at room temperature and without the need for alignment. The new pre-aligned room temperature CLC ink can be used as a substitute for conventional inks in almost all printing and plotting, and manual drawing and painting. Using the notch filter CLC platelets, the brightness is further enhanced.

  • Patent number: 6545792
    Abstract: The present invention includes a polarization independent optical interconnect device for selectively interconnecting a plurality of optical signals between a plurality of inputs and a plurality of outputs. The present invention may provide advantages typically associated with conventional polarization based switches, including terabit per second data rates and high speed switching, to facilitate use in fiber optic networks. Moreover, the switch of this invention is polarization independent, and therefore, may route either polarized or unpolarized light. Since both the input and output light may be unpolarized, the switch of this invention may have a high light efficiency (i.e. no losses associated with an input polarizer) and minimal insertion losses as compared to typical polarization based switches.

  • Patent number: 6541159
    Abstract: A solid-state hydroxide (OH−) conductive membrane provides up to five times higher ionic conductivity and surface oxygen exchange rate than conventional MIEC membranes, while operating at significantly lower temperatures and providing reduced overall system cost. The hydroxide conductive membrane utilizes a porous ceramic backbone, pores of which are injected with an electrolyte. A catalyst is provided as discrete layers disposed at the anode and cathode. The membrane of the present invention may be utilized in combination with an external voltage source to drive the oxygen generating reaction. Alternatively, the pores may be metallized and a pressure gradient utilized to drive the reaction. The membrane thus provides discrete materials to provide ionic conduction, electronic conduction, and structural support.

  • Patent number: 6485850
    Abstract: A novel metal-air fuel cell battery system with multiple cells and integrated apparatus for producing power signals with stepped-up voltage levels by selectively discharging the multiple cells. The system includes a plurality of discharging cells preferably formed by a cathode structure having plurality cathode elements, and an anode structure having one or more anode-contacting elements on an anode-contacting element support plate. Each cell can be independently activated (i.e. enabled) using a transistor-based power switching element operated under the control of a switching controller. The power switching elements are used to produce high-frequency electrical currents for generating stepped-up voltages, which are subsequently rectified and low-pass filtered. The power switching device elements may also be controlled to produce selectable output characteristics (voltage level, current, etc).

  • Patent number: 6394595
    Abstract: A computer-controlled system for producing a multi-color image on a substrate using multi-colored cholesteric liquid crystal (CLC) pigment materials made from CLC flakes tuned to predetermined bands of color. An image generator automatically generates an image specifying a pattern over which binder material is to be applied to a substrate by a binder material applicator. A plurality of CLC pigment applicators automatically apply patterns of different-color CLC pigment material to the pattern of binder material, which binds thereto as the binder material dries according to its drying characteristics. An output device is used to automatically return the substrate to a different one of CLC pigment applicators after each application of a pattern of different-color CLC pigment material to the pattern of binder material. The output device automatically repeats the return of the substrate to the CLC pigment applicators until all bands of color in the multi-color image are rendered.

  • Patent number: 6382264
    Abstract: A recyclable fuel distribution system comprising a hierarchy of operatively linked (with fuel supply and reaction product collection elements) fluid fuel transport vehicles, fluid fuel storage tanks, fuel supply reservoirs (optional depending on specific use), and fluid fuel usage devices operatively linked to the storage tanks or supply reservoirs, as applicable. The fuel, during use, undergoes a reversible chemical reaction, whereby collected reaction product is reversible to the original fuel. At least one and preferably all of the vehicles, storage tanks and reservoirs contain a storage volume with separated chambers, adapted to inversely change relative to fuel being supplied and reaction product being collected and stored. As a result, a single volume during transport, storage, and use, provides the dual function of fuel supply and collection of reversible reaction product, with concomitant nearly halving of transport, storage and use volumes and costs.
