Abstract: Collectible, rectangular ticket-type display device having a window in which is mounted a transparency type film frame or multi-frame clip for see-through type viewing. The display device preferably includes security and/or authentication indicia, and is fabricated from archival-quality materials. The ticket is formed from a single folded sheet of heavy paper or plastic material and scored along one edge for a fold to define a front and back panel. The film frame or clip is secured in an envelope or packet of non-bleed, non-yellowing transparent polyester plastic which is mounted to one inner face of the ticket panels. Preferably the ticket window is of sufficient size to exhibit the sprocket holes of the film frame or clip for authenticity. The transparency images may be of a motion picture or performance event such as a concert, sporting or historical event, and may be reproduced from a film positive or negative, or from video tape.

Abstract: An implant stimulator device uses tantalum and tantalum pentoxide as a system for the conveyance of electrical stimulation pulses from stimulus-forming circuitry contained within an hermetic enclosure to the saline fluids of body tissue to be stimulated. Internal coupling capacitors are not used, yet the danger of having DC current flow to the saline fluids is eliminated. A preferred embodiment provides a multiplicity of electrode contacts made from sintered, anodized tantalum, connected via tantalum wire leads to tantalum feedthroughs into the hermetically sealed package containing the stimulus pulse-forming electronic circuitry. One or more counter electrode contacts (for monopolar or bipolar configurations, respectively) made of activated iridium, non-activated iridium, iridium in combination with a noble or non-noble metal, platinum, gold, or other metal which forms a low impedance contact with body fluids, is/are connected via platinum or other conductive metal leads to return feedthroughs.
