    • The accuracy of a reverse geocode for a GPS fix in a mobile phone navigation device is improved significantly by considering together the user's last known location on an original route, the elapsed time between the last known location on the original route and the latest GPS fix, and the likelihood that the user could have travelled from the last known location on the original route to one of numerous candidate locations (generated from the reverse geocode) in the elapsed time. The navigation server relies only on a GPS fix, timestamps, and a back-end routing database to provide improved or superior accuracy of reverse geocoding a GPS fix (selection of a point on a road) when a relevant user has deviated from the intended route. The reverse geocoding allows for accurate and functional re-routing capabilities.
    • 通过考虑用户在原始路线上的最后一个已知位置,原始路线上的最后一个已知位置与最新的GPS定位之间的经过时间,将移动电话导航设备中的GPS修复的反向地理编码的精度大大提高, 以及在经过的时间内用户可能已经从原始路线上的最后一个已知位置行进到许多候选位置之一(由反向地理编码生成)的可能性。 导航服务器仅依赖于GPS定位点,时间戳和后端路由数据库,以便当相关用户偏离预期路线时,提供GPS定位(GPS选项)对路线进行反向地理编码的改进或更高精度 。 反向地理编码允许准确和功能重新路由功能。

    • A system for delivering power over a network of devices connected through a serial link includes a first and second differential pairs of wires. Each differential pair of wires is double AC coupled by a HPF on one side and by another HPF on an opposite side. An LPF connects a portion of each differential pair of wires between the HPFs to a voltage source, and another LPF connects that portion of each differential pair to a load. The system further includes a third and fourth differential pairs of wires. All four differential pairs of wires are located within a single cable, such as a CAT6 cable. The first, second and third differential pair of wires are used for video links, and the fourth differential pair of wires are used for the bi-directional hybrid link. A power delivery circuit in each device includes a voltage source, a power relay switch, a signature resistor for detection, and a load detector.
    • 用于通过串联链路连接的设备的网络上传送电力的系统包括第一和第二差分线对。 每条差分对的导线在一侧由HPF双相交流耦合,另一侧的另一个HPF耦合。 LPF将HPF之间的每对差分对导线的一部分连接到电压源,另一个LPF将每个差分对的该部分连接到负载。 该系统还包括第三和第四差动对的导线。 所有四条差分对的导线位于单根电缆内,如CAT6电缆。 第一,第二和第三差分线对用于视频链路,并且第四差分对导线用于双向混合链路。 每个装置中的电力输送电路包括电压源,功率继电器开关,用于检测的签名电阻器和负载检测器。
