    • A metal-ceramic composite (“cermet”) has been produced by a chemical reaction between a lithium compound and another metal. The cermet has advantageous physical properties, high surface area relative to lithium metal or its alloys, and is easily formed into a desired shape. An example is the formation of a lithium-magnesium nitride cermet by reaction of lithium nitride with magnesium. The reaction results in magnesium nitride grains coated with a layer of lithium. The nitride is inert when used in a battery. It supports the metal in a high surface area form, while stabilizing the electrode with respect to dendrite formation. By using an excess of magnesium metal in the reaction process, a cermet of magnesium nitride is produced, coated with a lithium-magnesium alloy of any desired composition. This alloy inhibits dendrite formation by causing lithium deposited on its surface to diffuse under a chemical potential into the bulk of the alloy.
    • 金属 - 陶瓷复合材料(“金属陶瓷”)已经通过锂化合物与另一种金属之间的化学反应产生。 金属陶瓷具有有利的物理性能,相对于锂金属或其合金的高表面积,并且容易形成为所需形状。 一个例子是通过氮化锂与镁的反应形成一种锂 - 氮化镁金属陶瓷。 该反应导致涂覆有一层锂的氮化镁颗粒。 氮化物在电池中使用时是惰性的。 它以高表面积形式支撑金属,同时稳定电极相对于枝晶形成。 通过在反应过程中使用过量的镁金属,制得氮化镁的金属陶瓷,涂覆有任何所需组成的锂 - 镁合金。 该合金通过使沉积在其表面上的锂在化学势下扩散到合金体中来抑制枝晶形成。

    • A method and system for watermarking and recovering a watermarked digitized image for subsequent authentication. The digitized image comprises spatial domain data signals reproduced from an original image. A transformer transforms the spatial domain data signals into frequency domain data signals, including respective magnitude and phase data signal components. Information is embedded into the magnitude data signals to develop modified data signals and the modified data signals are converted from the frequency domain to the spatial domain to generate the watermarked digitized image. For recovery, a second transformer transforms the spatial domain data signals comprising the respective original digitized image and watermarked digitized image into respective frequency domain dataset signals. A comparator responsive to the two transformer outputs compares the respective frequency domain dataset signals to identify the watermark and verify the authenticity of the image reproduction.

    • Embodiments of the invention include a method and apparatus for modulating data retrieved from page-wise memory systems such as holographic memory systems. The inventive method uses the detection of one or more test signals included within stored data image pages to estimate the behavior of the retrieved data image pages and to normalize the retrieved information accordingly. The method includes allocating a portion of the data image pages of interest for one or more determinable test signals and incorporating the test signal information into the data image pages prior to storage of the data image pages within the storage medium. Upon retrieval of the data image pages from the storage medium, the test signals are detected and used to form the basis of estimated data member behavior across individual data image pages and, alternatively, from one data image page to another. Based on the estimated behavior, appropriate normalization is performed on the data image pages. Advantageously, embodiments of the invention provide enhanced compensation for reproduction inconsistencies existing throughout the data image pages, e.g., inconsistencies inherently caused by holographic storage systems. Alternatively, the behavior estimation is supplemented with generation profiles indicating the behavior of data within the data image pages. The generated profile is used, e.g., to assist in normalizing the data image pages. Also, interpolation techniques alternatively assist the behavior estimation and/or the normalization of the data image pages.
