US Patent 7551076 Object locator feature as part of a security system

An object locator feature is incorporated into a security system that includes a user interface device with a display, keypad and associated transmitter. Wireless RF electronic tags with sounders are attached to different objects, e.g., an inanimate object, or a living being such as a child or pet. Each tag has an identifier such as a serial number that is learned to the user interface device by the user typing in the identifier of each tag. The user also types in descriptive information regarding the object with which the tag is associated, The user can edit the entries by adding or deleting objects, or changing the descriptive information. In a search mode, the user can select an object by its name or an assigned sequence number. In a polling mode, the electronic tags are periodically polled to confirm the presence of the associated object to the user.
