Abstract: A system and method for locating objects such as people, pets, and personal articles is described. A transceiver is attached to the person, animal, or item to be tracked and a handheld locator device is employed to transmit a locator signal containing an address code to the transceiver. Upon receipt of a signal, the transceiver compares the address code contained in the locator signal with an address code stored in the transceiver. If the two codes are same, the transceiver sends a return signal back to the locator device. The locator device uses this return signal to determine the distance and/or direction of the transceiver from the user's location. The system allows a user to select from a multiple number of items to locate and allows multiple users to search for different articles within the same general area without interference.

Abstract translation: 描述用于定位诸如人，宠物和个人物品的物体的系统和方法。 收发器附接到要跟踪的人，动物或物品，并且使用手持式定位器装置将包含地址码的定位信号发送到收发器。 在收到信号后，收发器将定位器信号中包含的地址码与收发器中存储的地址码进行比较。 如果两个代码相同，收发器将返回信号发送回定位器设备。 定位器设备使用该返回信号来确定收发器距离用户位置的距离和/或方向。 该系统允许用户从多个项目中选择定位并允许多个用户在不受干扰的情况下在相同的一般区域内搜索不同的物品。
