摘要： The present invention is a retractable/extendable diversity antenna that provides the appropriate polarization in a horizontal orientation. The antenna structure is placed within a Type II PCMCIA PC card package and may be extended or retracted with one touch. The antenna structure is large enough to provide for the diversity antenna design and may optionally be housed within a PCMCIA Type II PC Card. At least one spring-loaded mechanism is used to extend the antenna structure beyond the PCMCIA PC Card package and to provide stability while the antenna structure is in the extended position. The diversity antenna configuration may consist of either two miniature, planar antenna modules or two etched printed circuit board contours that are spaced as far apart as possible with a minimum separation of a quarter wave length distance in order to provide mitigation to radio multipath fading effects. The antenna modules have orientations perpendicular to each other such that the polar nulls representative of their radiation patterns remain spatially orthogonal.
摘要翻译：本发明是一种在水平方向上提供适当极化的可伸缩分集天线。天线结构放置在II型PCMCIA PC卡封装内，并可通过一触即可延伸或缩回。天线结构足够大以提供分集天线设计，并且可以可选地容纳在PCMCIA II型PC卡内。使用至少一个弹簧加载机构将天线结构延伸超过PCMCIA PC卡封装，并在天线结构处于延伸位置时提供稳定性。分集天线配置可以由两个微型，平面天线模块或两个蚀刻的印刷电路板轮廓组成，这两个蚀刻印刷电路板轮廓以最小间隔四分之一波长距离尽可能地间隔开，以便减轻对无线电多径衰落的影响。天线模块具有彼此垂直的取向，使得表示其辐射图案的极坐标空间保持在空间上正交。

摘要： An electromechanical machine includes a stator. A rotor is configured to rotate relative to the stator about a rotational axis. A coil extends about the axis and is wound on a bobbin. The bobbin surrounds the axis and has a circumferentially extending pocket in which the coil is located. The bobbin further has a circumferentially-extending overhang section that extends directly over at least a portion of the coil.

摘要： A communication module is provided having a movable electrically conductive interface. This module comprises a printed circuit board with a first slidably receiving contact surface for providing electrical connectivity to the movable electrically-conductive interface, a non-metallic sealant disposed about at least a portion of the first slidably receiving contact surface about which the movable electrically-conductive interface is formed, the sealant imposing negligible resistance to the movable electrically-conductive interface, and a second slidably receiving contact surface for traveling across the sealant disposed about the first slidably receiving contact surface thereby forming the movable electrically conductive interface. Also a method is provided for overlaying the non-metallic sealing element over the first slidably receiving contact surface.
