摘要： A system for organizing one or more accessory devices for a personal computer includes a first body structure that houses a first accessory device and an attachment unit detachably attached to the first body structure for attaching and detaching the first body structure mechanically to an outside surface of a personal computer (PC) component. According to the present invention, the attachment unit can be removed from the first body structure and attached to a second body structure that houses a second accessory device so that the second body structure can be attached to the PC component.

摘要： The invention improves the ability of the FS demodulator-circuit of an FS digital transmission system so as to withstand noise with low error count. The invention uses two different types of all pass networks and a phase measuring circuit to average random noise and enhance the desired FS frequencies.

摘要： A document feed mechanism is disclosed for feeding documents from the bottom of a stack. Sheet separating rolls prevent the feeding of more than one sheet at a time through a nip formed by the separating rolls and feed rolls. Wear compensation means functions to uniformly distribute wear about the cicumference of the separation rolls. The wear compensation means additionally provides for axial shifting of the separator rolls relative to the feed rolls so that a constant gap or nip is maintained. Simplified means for adjusting the gap are also disclosed. The feed mechanism will accept documents having a relatively wide range of thicknesses without adjustment.
摘要翻译：公开了用于从堆叠的底部馈送文件的文档馈送机构。片材分离辊通过由分离辊和进给辊形成的辊隙一次一次地进给多个片材。磨损补偿是指均匀分布磨损的功能。磨损补偿装置另外提供了分离辊相对于进料辊的轴向移动，从而保持恒定的间隙或辊隙。还公开了用于调整间隙的简化方法。进给机构将接受具有相对宽的厚度范围的文件而不进行调整。
