    • A protective structure for a vehicle having an opening on an upper surface is provided. One embodiment of the invention has at least a partial enclosure around an area defined laterally by the vehicle opening with an overhead and side protective capability. An embodiment of the invention has an overhead cover that is formed to substantially enclose a top area of the enclosure and having multiple panels that may be locked into place or opened by an occupant for exit through a top area of the enclosure. The multiple panels in this embodiment extend upwardly and inwardly from a section of the enclosure's side walls. Ballistic windows are provided on the protective structure such that an occupant can view laterally and vertically through the enclosure and overhead cover. A shield or protective plate can be mounted on one side of the enclosure.
    • 提供了在上表面具有开口的车辆的保护结构。 本发明的一个实施例具有围绕由车辆开口横向定义的具有顶部和侧面保护能力的区域中的至少一部分外壳。 本发明的实施例具有顶盖,其被形成为基本上封闭外壳的顶部区域并且具有多个面板,其可以被锁定到位或由乘员打开以通过外壳的顶部区域排出。 该实施例中的多个面板从外壳侧壁的一部分向上和向内延伸。 在保护结构上设置有弹道窗,使得乘客可以横向和垂直地观察外壳和顶盖。 屏蔽或保护板可以安装在外壳的一侧。

    • Systems and methods of eliminating or reducing interference resulting from harmonics of local oscillator frequencies of mixers are shown. In one embodiment, a determination is made as to a zone or zones within an intermediate frequency band associated with undesired spurs. Inter-tuner spurs and intra-tuner spurs may be identified such that frequency information of the identified spurs may be utilized to define a plurality of exclusion zones. Local oscillator frequencies may subsequently be efficiently selected in view of the exclusion zone information. Embodiments may also determine a score for identified spurs which may be used to optimally select from within a set of spur-generating local oscillator frequencies.
    • 示出了消除或减少由混频器的本地振荡器频率的谐波引起的干扰的系统和方法。 在一个实施例中,确定与不期望的刺激相关联的中间频带内的区域或区域。 可以识别相互调谐器之间的杂散和调谐器内部的杂散,使得所识别的杂散的频率信息可以用于定义多个排除区。 考虑到排除区域信息,随后可以有效地选择本地振荡器频率。 实施例还可以确定用于所识别的杂散的分数,其可以用于在一组产生振荡的本地振荡器频率内进行最佳选择。
