    • The invention provides a real-time package tracking system for use by a package delivery service. The system includes a vehicle operable to deliver a package to a destination of a customer within a region, a positional location system (e.g. GPS) carried by the vehicle, the positional location system being operable to determine geographic positional coordinates for sequential locations of the vehicle along the route thereof toward said destination. The system also includes a wireless transmitter means (such as a cell phone link) carried by said vehicle, for transferring the aforesaid geographic positional coordinates to a central computer. The computer is operable to providing periodic updated calculations to periodically estimate corresponding estimated arrival time (ETA) data for the specific package to said destination and to supply the aforesaid estimated arrival time data to said customer. According to preferred embodiment, the customer can view a map with the ETA information and can make selections on line (e.g. new ETA, or complete cancellation of delivery). These choices are then used to recalculate the drivers route, and can be displayed for both the dispatcher and the driver as well.
    • 本发明提供了一种用于包装递送服务使用的实时包裹跟踪系统。 该系统包括可操作以将包裹递送到区域内的客户的目的地的车辆,由车辆携带的位置定位系统(例如,GPS),该位置定位系统可操作以确定车辆的顺序位置的地理位置坐标 沿其路线朝向所述目的地。 该系统还包括由所述车辆承载的用于将上述地理位置坐标传送到中央计算机的无线发射机装置(诸如蜂窝电话链路)。 计算机可操作以提供定期更新的计算,以周期性地估计针对所述目的地的特定包的相应估计到达时间(ETA)数据,并将上述估计到达时间数据提供给所述顾客。 根据优选实施例,客户可以查看具有ETA信息的地图,并且可以在线进行选择(例如,新的ETA或完全取消交货)。 然后,这些选项用于重新计算驱动程序路由,并且也可以为调度程序和驱动程序显示。

    • The system employs full transceivers, each having peer-to-peer, client/server, and IP networking capabilities, and covering open-area ranges of up to 100 feet. The system uses Low Frequency for data communications so it can achieve both low cost (less costly than many RF-ID tags) and long battery life (10-15 years). Additionally, since these tags have batteries, static RAM maybe be added at very low cost, as well as sensors, LED's displays etc. The system also employs a sidewinder that communicates to said tag regularly, said sidewinder keeps the IP address of said tag. The system also employs an embedded VPN. The VPN includes a suite of diagnostic tools that run on a laptop. The system also includes a visibility data server that communicates to the sidewinder by the VPN. The data server includes a virtual tag data base, said virtual tag data base updated by the sidewinder.
    • 该系统采用完整的收发器,每个收发器具有点对点,客户端/服务器和IP网络功能,并覆盖高达100英尺的开放范围。 该系统使用低频进行数据通信,因此可以实现低成本(比许多RF-ID标签更便宜)和更长的电池寿命(10-15年)。 此外,由于这些标签具有电池,因此可以以非常低的成本添加静态RAM,以及传感器,LED显示器等。该系统还采用定期与所述标签通信的侧卷器,所述侧卷纸保持所述标签的IP地址。 该系统还采用嵌入式VPN。 VPN包括一套在膝上型计算机上运行的诊断工具。 该系统还包括一个可视数据服务器,它通过VPN与主持人进行通信。 数据服务器包括虚拟标签数据库,所述虚拟标签数据库由所述侧挂方更新。
