摘要： A charge storage cell is made up of two electrodes spaced apart by a dielectric layer incorporating a molecular switch. A method of operating a bi-stable, molecular switch charge storage cell encompassing two electrodes spaced apart by a dielectric layer incorporating a molecular switch having an electric dipole is also disclosed. The method involves applying a voltage across said dielectric layer to induce opposing charges on said electrodes that create an electric field across said dielectric layer, wherein molecular dipoles within said dielectric layer align or change in response to said electric field, creating an opposing electric field and a change in state of said molecular switch from a first state to a second state; and applying a voltage of reverse polarity across said dielectric aver to change said state of said molecular switch from said second state to said first state.

摘要： An electric field activated bi-stable molecular system configured within an electric field generated by a pair of electrodes is provided for use, e.g., as electronic ink or other visual displays. The molecular system has at least one rotor portion connected to at least one stator portion, wherein the rotor portion rotates with respect to the stator portion between at least two different states upon application of the electric field, thereby inducing a band gap change in the molecular system, wherein in a first state, there is extended conjugation throughout the major portion of the molecular system, resulting in a relatively smaller band gap, and wherein in a second state, the extended conjugation is destroyed, resulting in a relatively larger band gap. A primary advantage of the molecular system is improved contrast. Because the colorant of the present invention is molecular and thus effectively monoplanar, there should be no backside reflection or scattering from the colorant. A second advantage of the present invention is improved resolution. Finally, each molecule of the present invention will latch to stabilize one or the other of its color states.
摘要翻译：提供了由一对电极产生的电场内配置的电场激活的双稳态分子系统，例如用作电子墨水或其它视觉显示器。分子系统具有连接至少一个定子部分的至少一个转子部分，其中转子部分在施加电场时在至少两个不同状态之间相对于定子部分旋转，由此引起分子中的带隙变化系统，其中在第一状态下，在分子系统的整个主要部分存在延伸的共轭，导致相对较小的带隙，并且其中在第二状态下，扩展的共轭被破坏，导致相对较大的带隙。分子系统的主要优点是对比度提高。因为本发明的着色剂是分子且因此有效地是单面的，所以不应该有着色剂的背面反射或散射。本发明的第二个优点是分辨率提高。最后，本发明的每个分子将锁定以稳定其一个或多个其颜色状态。

摘要： Multiple electroluminescent (EL) emitters are constructed from layers deposited on a substrate and incorporated with a broadband sensor to form a colorimeter. The EL emitters produce light covering spectral segments determined by a filter layer and an active layer wherein the spectral segments sufficiently cover the visible spectrum to enable a wide range of colors to be accurately measured. The colorimeter is mounted in a desktop color printer to measure the color content of printed images and to calibrate the printer.

摘要： Light filter apparatus for receiving a light beam having wavelengths in a selected band and for dispersing the light into a plurality of rays, with each ray having a different wavelength for which the intensity peaks. The peak wavelength varies approximately continuously with displacement of spatial position in a chosen direction along the filter's light-receiving plane. In one embodiment, the filter is a modified etalon structure having at least two reflecting surfaces whose separation distance is not constant but increases or decreases monotonically with distance in a chosen direction in a light-receiving plane of the etalon. Each of these two reflecting surfaces may be planar or non-planar but continuous, or may have a step or staircase configuration. This structure may operate using transmitted light or reflected light. In a second embodiment, an edge filter combination is used to produce a narrow band of transmitted or reflected light having a variable central wavelength that varies with position along the chosen direction. In a third embodiment, a multi-layer thin film structure is used to provide a narrow band of transmitted or reflected light having a variable central wavelength. The filter may be combined with a one-dimensional or two-dimensional array of photosensor elements, which array may be linear, circular or generally curvilinear, one such element receiving a group of adjacent light rays of similar peak wavelength, to provide a plurality of different wavelength readings on an incident light beam for spectrophotometry or colorimetry analysis.
