    摘要： The invention relates to variable focus lenses based on magneto wetting and related devices, wherein two fluids, one of which is magnetically susceptible, are in contact over a meniscus. The shape of the meniscus is controlled by means of an applied magnetic field gradient. The contact angle between the chamber wall and the meniscus is a conserved. Implementation of special shaping to the internal or external walls of the chamber, while conserving the contact angle, results in better lens shape in the variable focus lens and lower levels of lens distortion.

    摘要： In the invention, e-book information is distributed on un-cartridged small media that can be made cheaply enough for use in free distribution of information. The e-book information is encoded and stored on a read-only optical disc that is 2 to 4 cm in diameter and 0.6 to 1.2 mm thick, the information being encoded with sufficient redundancy and sufficient tolerance for missing information that the disc can be conveniently handled and pocketed without losing reliability of information access. The disc has a lead-in area that is prior to all the e-book information and that contains a disc navigation area, and a lead-out area that follows all the e-book information. The disc may include multiple partitions, each partition containing sufficient access information for independent access of the e-book information within the partition without accessing any other partition. Alternatively, the disc may include multiple slots for files and that are equally spaced. For example, to provide data redundancy, at least some of the partitions are duplicate partitions that contain all the same data as another duplicate partition, and the disc navigation area contains partition descriptors that indicate all the partitions and the areas allocated to each of the partitions, and the disc also includes duplicates of the partition descriptors, the duplicate partition descriptors being stored in the lead-in area or in the lead-out area to provide redundancy of navigation information.

    摘要翻译： 在本发明中，电子图书信息被分发在可以被制成廉价足够用于免费分发信息的非小型小型媒体上。 电子书信息被编码并存储在直径为2至4cm，厚度为0.6至1.2mm的只读光盘上，该信息被编码具有足够的冗余度和足够的公差以用于该盘可以方便地丢失的信息 处理和口袋不丢失信息访问的可靠性。 该光盘具有在所有电子图书信息之前的导入区域，并且包含光盘导航区域以及跟随所有电子图书信息的导出区域。 光盘可以包括多个分区，每个分区包含足够的访问信息，用于独立访问分区内的电子图书信息，而不访问任何其他分区。 或者，盘可以包括用于文件的多个槽，并且间隔开。 例如，为了提供数据冗余，至少一些分区是包含与另一个重复分区相同的数据的重复分区，并且光盘导航区域包含指示分配给每个分区的所有分区和区域的分区描述符 ，并且盘还包括分区描述符的重复，重复的分区描述符存储在导入区或导出区中，以提供导航信息的冗余。
