ABSTRACT:
A locator system includes two main components, namely, (1) a beacon tag that is readily attached to a person or article, and (2) a transportable finder or receiver/processor for sensing the relative position of the tag and indicating changes in that relative position to a user. The method for locating a person or article preferably uses an audible feedback signal to the user for informing the user, when moving, whether the relative position of the beacon tag is getting closer to the finder or farther from the finder. The locator system includes at least one beacon tag comprising a transmitter programmed to transmit a unique coded pulse signal. The beacon tag is housed in a lightweight portable envelope or container and includes a battery, an antenna, a large programmed gate array and a frequency reference (e.g., a crystal oscillator).
