An extended-range reader for use in identifying the tag of an object. The reader includes a winding of conducting wire for generating an interrogating magnetic field. The winding may be either a coil assembly consisting of a plurality of coils spaced at intervals along a common axis or a solenoid. The winding is limited to those having values of D/L less than four where D is the smallest transverse dimension of the winding and L is the length. The winding is adapted to receive a structure within the winding for providing objects a passageway through the winding. The axis of the winding may be either straight or curved. To improve the magnetic field generating capability of the winding, a magnetic shunt encircling the winding can be added. Also included is a structure within the winding for providing objects a passageway through the winding, the structure having openings for object ingress and egress. Where the structure is intended to provide a natural environment for the objects, the structure, except for the openings, can be made pervious or impervious to liquids or gases.

The hypodermic syringe for implanting objects in the bodies of birds, fish, animals, and humans consists of a barrel, a canula attached to one end of the barrel, and a plunger that can be moved back and forth within the barrel. A user implants an object by placing the object inside the canula, making an incision with the canula, and then pushing on the plunger thereby causing the object to move from the canula through the incision and into the body. The canula is designed to securely hold an implant object in a fixed position within the canula from the moment of insertion into the canula until the moment of implantation. The canula is also provided with a window that permits a user to observe the presence of an object and, in the case of objects that are electronic identification tags, to read the data stored in a tag with electromagnetic readers. The plunger is intended to provide the user with the same 'feel' as a conventional fluid-injection-type hypodermic syringe. The plunger is also equipped with a pressure-release mechanism to avoid the undesirable effects of air pressure build-up in the barrel which may occur when the plunger is operated by a user.

A container providing selective access to stored objects consists of a plurality of cells for storing objects and a mechanism for causing the cells to open and close in accordance with a control pattern that specifies the cells that are to be opened and the cells that are to be closed. A user, by selecting an appropriate control pattern gains access to those cells in which he has an immediate interest. The user may quickly gain access to other combinations of cells simply by selecting other control patterns.
