    • The present disclosure relates generally to locating systems, and more particularly, to handheld locator systems for locating personnel or other objects in buildings or other environments. In one illustrative embodiment, a tag is attached to an object to be located (e.g. firefighter). The tag may be configured to emit a first signal and a second signal, where the first signal and the second signal having disparate propagation characteristics in the environment. In some cases, the first signal may be an acoustic signal and the second signal may be an RF signal, but this is not required in all embodiments. By using a first signal or set of signals, and then automatically switching to another signal or set of signal(s) when the first signal or set of signals are not received clearly, the tag/receiver system may help mitigate the failure modes/weaknesses of any single technology, and may provide advantages over use of any of the technologies used singly.
    • 本公开一般涉及定位系统,更具体地,涉及用于在人造建筑物或其他环境中定位人员或其他物体的手持定位器系统。 在一个说明性实施例中,标签附接到要定位的对象(例如消防员)。 标签可以被配置为发射第一信号和第二信号,其中第一信号和第二信号在环境中具有不同的传播特性。 在一些情况下,第一信号可以是声信号,第二信号可以是RF信号,但是在所有实施例中不是必需的。 通过使用第一信号或一组信号,然后当第一信号或一组信号没有被清楚地接收时,自动切换到另一个信号或一组信号,标签/接收机系统可以帮助减轻故障模式/弱点 任何单一技术,并且可以提供优于使用单独使用的任何技术的优点。
