20130038446 | LOCATOR SYSTEM USING DISPARATE LOCATOR SIGNALS - 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. | 02-14-2013 |
