    • A wireless communication system (100) employs a method (700) and apparatus for automatically tracking locations of wireless communication devices (102, 104, 106) in a geographic area, such as an ad hoc area of an emergency scene, that is divided into two or more zones (108, 110, 112). A wireless communication device (102) or a host device (122), determines a location of the wireless device (102). The wireless device's location is then associated with one of the zones (108, 110, 112). An indication (410) of a zone change is presented to a user of the wireless device and/or the host device (102, 122), as applicable, in the event that the wireless device's location reflects a transition of the device from one zone to another. Alternatively, each wireless device (102, 104, 106) might be associated with a corresponding group, such as a fire department, and the zone change indication might include an identifier (412) of the wireless device's group.
    • 无线通信系统(100)采用一种方法(700)和装置,用于自动跟踪地理区域(例如紧急情况的自组织区域)中的无线通信设备(102,104,106)的位置,该区域被划分为 两个或多个区域(108,110,112)。 无线通信设备(102)或主机设备(122)确定无线设备(102)的位置。 无线设备的位置然后与其中一个区域(108,110,112)相关联。 在无线设备的位置反映设备从一个区域的转变的情况下,区域改变的指示(410)被呈现给无线设备和/或主机设备(102,122)的用户,如适用的, 到另一个 或者,每个无线设备(102,104,106)可以与诸如消防部门的对应组相关联,并且区域改变指示可以包括无线设备组的标识符(412)。

    • A method of increasing location accuracy in an inertial navigational device (100) is described herein. The navigational device (100) generates real-time data to depict its location. The data comprises at least one of sensor data, motion data, and location data. The navigational device (100) transmits the real-time data to a second device (104) in a real-time fashion. The navigational device (100) receives an update message from the second device (104), based on a comparison of the real-time data generated by the navigational device (100) against a second set of data. The navigational device (100) adjusts its depicted location based on the update message in order to increase the location accuracy of the navigational, device (100). Alternatively, the navigational device (100), absent the second device (104), can compare the real-time data generated against the second set of data internally and adjust its depicted location accordingly.
    • 本文描述了在惯性导航装置(100)中提高定位精度的方法。 导航设备(100)生成实时数据以描绘其位置。 数据包括传感器数据,运动数据和位置数据中的至少一个。 导航装置(100)将实时数据以实时方式发送到第二装置(104)。 导航设备(100)基于由导航设备(100)生成的实时数据与第二组数据的比较,从第二设备(104)接收更新消息。 导航设备(100)基于更新消息来调整其描绘的位置,以便增加导航设备(100)的定位精度。 替代地,不存在第二设备(104)的导航设备(100)可以在内部生成的实时数据与第二组数据进行比较,并相应地调整其描绘的位置。

    • A system (400, 500) and method (800) of personal inertial navigation measurements can include measuring (802) an angle, measuring (804) an angular velocity independent of an angle measurement, measuring (806) an angular acceleration independent of the angle measurement and independent of an angular velocity measurement, and combining (808) the angle measurement, the angular velocity measurement, and an angular acceleration to provide an angled output. The angle measurement can be measured using a compass or magnetic field, the angular velocity can be measured using a gyroscope (such as a MEMS gyroscope), and the angular acceleration measurement can be measured using an angular accelerometer (such as a molecular electronic transfer device having a magneto hydrodynamic effect device). The method can further include suppressing (810) noise caused by the angle measurement by using a sample and hold circuit (504) controlled by a higher ordered component to suppress noise from a lower ordered component.
    • 个人惯性导航测量的系统(400,500)和方法(800)可以包括测量(802)角度,测量(804)与角度测量无关的角速度,测量(806)与角度无关的角加速度 测量并且独立于角速度测量,并且组合(808)角度测量,角速度测量和角加速度以提供成角度的输出。 可以使用罗盘或磁场测量角度测量,可以使用陀螺仪(例如,MEMS陀螺仪)来测量角速度,并且角加速度测量可以使用角加速度计(例如分子电子转移装置 具有磁流体动力学效应装置)。 该方法还可以包括通过使用由较高阶分量控制的采样和保持电路(504)来抑制(810)由角度测量引起的噪声,以抑制来自低阶分量的噪声。
