摘要： In one embodiment, a method provides multiple-tone wideband I/Q mismatch calibration. A plurality of calibration frequencies is selected within a channel. A calibration tone is applied to the channel at each of the plurality of calibration frequencies. An I/Q mismatch is estimated at each of the plurality of calibration frequencies. An n-th order filter is constructed to compensate received signals relative to the estimated I/Q mismatch related to each calibration frequency.

摘要： A method for matching navigational routes that are generated by separate route generators and are used by vehicle navigation systems. According to one embodiment, a user previews a first navigational route generated by a first route generator, such as those incorporated in a navigation-related website. From this first navigational route, a variety of location markers corresponding to different points along the route are generated. The location markers are then sent to a second route generator used by a vehicle navigation system, so that it can generate a second navigational route that is similar to the first route. The second navigational route is then sent to a navigation unit located on the vehicle, so that the driver can be given directions that generally correspond to the first navigational route which they initially reviewed on the navigation-related website.
摘要翻译：用于匹配由单独的路线发生器产生并由车辆导航系统使用的导航路线的方法。根据一个实施例，用户预览由第一路由生成器生成的第一导航路由，例如并入导航相关网站中的那些。从该第一导航路线，生成对应于沿着路线的不同点的各种位置标记。然后将位置标记发送到由车辆导航系统使用的第二路线发生器，使得其可以生成类似于第一路线的第二导航路线。然后将第二导航路线发送到位于车辆上的导航单元，从而驾驶员可以获得与导航相关网站上初步审查的第一导航路线大致对应的指示。

摘要： An ice fish house base has at least two skis, each coupled through at least two pivotal arms to an ice house base. The pivotal arms are pivotal between an elevated position and a lowered minimum position. The lowered position is stable when the ice house base comes into solid contact with the ground, thereby limiting maximum rotation in this ice-house-base-lowered position. In the upward position, a rotational pivotal arm stop prevents the pivotal arms from rotating further, so that the separation between ice house base and skis is just less than maximum. The weight of the ice house will also hold the ice house base at this fully rotated position. A quick attach receiver is provided for a bifurcated ice auger mount and several alternative accessory supports. In addition, several alternative trailer hitch couplers are disclosed that use a tensioning strap for securement.
摘要翻译：一个冰鱼屋基座至少有两个滑雪板，每个滑雪板通过至少两个枢转臂连接到冰屋基地。枢转臂在升高位置和降低的最小位置之间枢转。当冰屋基地与地面牢固接触时，降低的位置是稳定的，从而限制了这个冰屋下降位置的最大旋转。在向上的位置，旋转枢转臂止动件防止枢转臂进一步旋转，使得冰屋底座和滑雪板之间的分离刚好小于最大值。冰屋的重量也将在这个完全旋转的位置保持冰屋基地。提供了一个快速连接接收器，用于分叉的冰螺旋式安装座和几种替代的附件支撑。此外，公开了使用张紧带固定的几种替代的拖车联结器。
