  • Patent number: 7148801
    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.

  • Patent number: 4779151
    Abstract: An automated tape cassette sequencing system includes a cassette storage library containing a plurality of columns of storage bins facing an interior space within which a cassette manipulator is located. The manipulator moves cassettes between the storage bins and tape transport units which also face the interior space. Rotary loading and unloading mechanisms are provided in openings in the housing of the library and include one or more storage bins. The mechanisms are rotatable from a first position in which the storage bins face outwardly through the openings to a second position in which the storage bins face the interior space of the library. Cassettes can be loaded and unloaded by an operator while the mechanisms are in their first position and handled by the manipulator assembly while the mechanisms are in their second position.

  • Patent number: 4654727
    Abstract: A tape cassette handling and sequencing system includes a large storage library having a plurality of storage bins and a cassette loading section for receiving cassettes to be stored in the storage bins. Tape transports are provided for playing cassettes stored in the library. A manipulator assembly moves cassettes between the loading section, storage bins and tape transports. The design facilitates the automatic sequencing of a large number of cassettes thus freeing an operator for other tasks.
