    • A system and method for updating and communicating traffic information to at least one receiving vehicle includes a traffic information center and at least one probe vehicle. In a preferred embodiment, major road sections are represented as links, the center stores and updates a parent map database of links that are associable with a first value of a condition, each probe vehicle is configured to receive a copy of the database either periodically or upon request, determine a second value of the condition, and compare the first and second values to determine a condition discrepancy. Where the discrepancy surpasses a threshold, each probe vehicle is further configured to upload at least the second value to the center, so as to update the parent map database.
    • 用于向至少一个接收车辆更新和传送交通信息的系统和方法包括交通信息中心和至少一个探测车辆。 在优选实施例中,主要道路部分被表示为链接,中心存储并更新与条件的第一值相关联的链接的父图谱数据库,每个探测车辆被配置为周期性地接收数据库的副本, 根据请求确定条件的第二值,并比较第一和第二值以确定条件差异。 在差异超过阈值的情况下,每个探测车辆还被配置为至少将第二值上传到中心,以便更新父图谱数据库。

    • The described principles provide a method and system for identifying a potentially closed road based on reroute requests, and of accommodating the potential road closure while continuing to test the road status periodically via routing decisions and rerouting requests. While the optimal route assumes that the potentially closed road is open, a replacement route is defined assuming that the potentially closed road is closed. A fraction of users are sent along the optimal route, and if a reroute request is received, the potentially closed road is assumed to be closed still. The affected user is rerouted to a recovery route that matches the optimal route up to the potentially closed road, and then differs from the optimal route thereafter to avoid the potentially closed road.
    • 所描述的原理提供了一种用于基于重新路由请求识别潜在封闭道路的方法和系统,并且通过路由决定和重新路由请求周期性地继续测试道路状态来容纳潜在的道路封闭。 虽然最佳路线假定可能封闭的道路是敞开的,但假设可能封闭的道路关闭,则定义替换路线。 按照最佳路线发送一小部分用户,如果收到重新路由请求,则假设潜在的封闭道路静止。 受影响的用户被重新路由到与最佳路由匹配的恢复路由,直到潜在的封闭道路,然后与最佳路由不同,以避免潜在的封闭道路。

    • A device and method for mounting electrical boxes (1) in preexisting drywall (4) using a mounting bracket (3). To use, a holding wire (14) having a stop (15) on one end is placed through a screw hole (9) of a cover (2) which is attached the electrical box. Then the electrical box and cover are placed sideways through a wall hole (7) in the drywall. Next the electrical box is lowered behind the wall so that conduit (8) may be connected to the electrical box. Then a mounting bracket (3) is secured to the cover and electrical box with holding clips (11) and screws (12) using the holding wire to keep the mounting bracket and cover centered with the wall hole. A standard switch or outlet cover may then be installed to cover the mounting bracket. An additional novel feature of the present invention is a stop strap (17) which may be attached to conduit above a top plate (10) of a wall to bold the conduit in place.
    • 一种用于使用安装支架(3)将电气箱(1)安装在预先存在的干式墙壁(4)中的装置和方法。 为了使用,在一端具有止动件(15)的保持线(14)通过安装在电箱上的盖(2)的螺孔(9)放置。 然后将电气箱和盖子横向放置在墙壁上的墙壁(7)中。 接下来,将电箱降低在墙壁后面,使得导管(​​8)可以连接到电箱。 然后,使用保持线将安装支架(3)固定到具有固定夹(11)和螺钉(12)的盖和电箱上,以将安装支架和盖保持在壁孔的中心位置。 然后可以安装标准开关或出口盖以覆盖安装支架。 本发明的另一个新颖特征是阻挡带(17),其可以附接到壁的顶板(10)上方的导管上,以将导管加粗就位。
