Abstract: A product packaging comprises a cap on a transparent bottle to seal in a protected product. The cap includes an RFID chip and antenna that can report a serial number and product identification code to a nearby scanner. Reports from several such scanners in the distribution chain from manufacturer to retailers are logged and used to validate legitimate products by their movements. The caps are designed such that when opened the RFID antenna will break away from its associated RFID chip. The cap is molded of cross-linked polymers with a memory that makes it impossible to reseat it properly to the bottle once removed. A hologram target is placed backwards under a label on the side of the bottle so a laser beam can be directed through the backside of the bottle, through the contents, and to the hologram. The reflected laser light will have a signature that is very sensitive to the exact chemistry of the contents.

Abstract: A product security system includes an RFID chip and antenna that are polymerized onto separable parts of a commercial product package. The RFID chip includes a unique serial number that can be interrogated by a wireless reader. A database of such unique serial numbers associated with particular manufacturing production runs is used in a method to detect counterfeiting. The RFID chip and antenna are embedded such that attempts to remove or transfer them will be obvious to an inspector.

Abstract: A method of manufacturing a flexible recording disk with a reinforced aperture region comprising the steps of transferring uncured polymeric material to a printing plate having an elastomeric protrusion thereon, transferring at least a portion of the uncured polymeric material from the elastomeric protrusion to a region on a surface on a flexible magnetic material, curing the polymeric material, and cutting a flexible disk from the flexible magnetic material such that the disk has a central aperture surrounded by the region of the flexible material coated with the cured polymeric material.

Abstract: A method for cold-forming light gauge polymer sheet material by application of localized heat to the area of the fold. In the manufacture of Lexan polycarbonate flexible magnetic disk jackets, heat is applied to the folded edge by a heating element generally maintained uniformly at 375.degree. F. The heating element contacts the folded Lexan polycarbonate edge in a U-shaped trough having planar sidewalls generally perpendicular to a planar bottom wall.

Abstract: An improved floppy disk having a liner material into the fibers of which has been compounded identically the same lubricant as that compounded into the surface of the magnetic recording disk.

Abstract: An improved wet cleaning disk assembly for use in cleaning reading and writing transducers of a floppy disk drive. The cleaning disk assembly includes an envelope having apertures formed therethrough for receiving reading and writing transducers and a reinforced opening along one edge thereof for insertion of a cleaning disk thereinto. In use, a cleaning disk, presoaked with a liquid cleaning solution, is removed from a sealed package and inserted into the envelope to form the cleaning assembly which is then inserted into a floppy disk drive. A spindle within the drive passes through a central aperture therefor in the envelope and through a central aperture in the disk to thereby engage the disk and rotate it within the envelope. The envelope and cleaning disk also include sensing apertures adapted to permit optical sensing of disk rotation by the drive.

Abstract: Apparatus and method for rapidly removing fuzz from about the edges of sheets of material and apertures within those sheets without damaging the sheet material performed by passing the sheet quickly through a flame.

Abstract: A method for cold-forming light gauge polymer sheet material by application of localized heat to the area of the fold. In the manufacture of Lexan polycarbonate flexible magnetic disk jackets, heat is applied to the folded corner by a heater bar generally maintained uniformly at 375.degree. F. The heater bar contacts the folded Lexan polycarbonate edge in a U-shaped trough having planar side walls generally perpendicular to a planar bottom wall.
