  • Patent number: 9308774
    Abstract: The present invention relates to a security element composed of at least one light-transmitting substrate on which a substantially opaque, screened layer composed of grid elements is located. According to the present invention, within the substantially opaque, screened layer composed of grid elements, at least one thin, solid, substantially opaque line is arranged that exhibits the form of at least one alphanumeric character, a graphic or a pattern. Such lines have line widths of at least 0.1 mm to 5 mm, preferably of 0.2 mm to 0.7 mm, particularly preferably of about 0.5 mm. Instead of lines, also extensive regions without any gap may be used, such that the alphanumeric character, pattern or graphic formed is perceptible only in transmitted light, but not in reflected light. The security element thus displays, at least when viewed from the side of the substantially opaque, screened layer, in top view, a different appearance than when looked through.

  • Patent number: 8978991
    Abstract: A composite image is generated from a decorative image, a bar code, and one or more filter patterns. The composite image visually approximates the decorative image, yet the composite image is machine-readable by a scanner capable of reading the bar code, and the composite image encodes the same data as the bar code. Filter patterns provide a flexible way to generate the composite image by selectively updating the decorative image. Updates may be applied in only the locations where necessary, and only by the amount necessary, in order for the composite image to be recognized as a bar code. Also, updates may be applied in arbitrary color spaces, including color spaces where brightness can be altered with less impact on human color perception.

    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 card authentication is performed. An authentication chip for performing authentication by a copy-disabled hologram chip is attached to a card and when or after the card is introduced into a handling device, the authentication chip information is read to perform authentication. Read may be performed in a planar shape but a linear shape can reduce the processing load. An arbitrary straight line or a curved line may be used as a read line shape by modifying the read position in association with the card movement when the card is placed to be read. When the card introduced to a terminal device is an unauthorized one, the card is ejected or an alarm is issued when the card is introduced inside.

  • Patent number: 7485499
    Abstract: Non-volatile data memory cards, flash drives and other memory devices are customized by manufacturing core memory units all the same and then covering them by outer skins which may be made to have different appearances and/or tactile characteristics. The skins are slid over the core memory units by hand from one end. End users of such memory devices may then select how they will look and feel by separately purchasing covers. Sellers of such memory devices may more easily control how their products look and feel.

  • Publication number: 20090014522
    Abstract: A holographic read only memory card which can be coupled to and read by a card reader to which electronic read only memory cards can also be coupled to and read by the card reader is disclosed. The holographic read only memory card comprises: a housing having a compartment for receiving a holographic storage medium; a holographic storage medium having stored thereon holographic data; and optionally a an electronics panel member having an electronic memory component which can be read by the card reader when the holographic read only memory card is coupled to the electronic card reader. The housing comprises one or more card locating members to thereby repeatedly position the holographic read only memory card each time the holographic read only memory card is coupled to the electronic card reader so that the holographic data can be read.

  • Publication number: 20080245865
    Abstract: Multi-layer cards with aesthetic and/or functional features, e.g. banking, access, or identification cards, having a bearing layer that includes an effects layer disposed directly between two core layers are disclosed herein. Among other potential benefits, the layered structure of the bearing layer reduces overall manufacturing costs, as compared to methods known in the art, by facilitating a balanced card construction while minimizing the number of layers formed from relatively expensive materials, avoiding direct imaging of the effects layer and minimizing waste associated therewith, as well as providing for reliable incorporation of the effects layer into the multi-layered structure with minimal expenditure of resources and reduced possibility of waste.

  • Patent number: 7407101
    Abstract: A card embodying the invention includes marks which are randomly formed within a dedicated region of the surface of the card. The randomly formed marks may, for example, include; (a) partial-holes extending a short distance from a surface of the card; (b) through-holes extending between the top and bottom surfaces of the card; (c) burn marks, or (d) ink marks. The marks are of a size and nature such that they are not readily visible to the naked eye. The invention includes illumination apparatus for illuminating the card to reliably sense the optical pattern of the randomly formed marks. In accordance with one aspect of the invention, a reader/writer includes apparatus for generating an array of light to uniformly illuminate the back surface of the card so as to pass light through the through-holes or through the partial holes.

  • Patent number: 7391911
    Abstract: An apparatus for compressing holographic data includes an image capture device for capturing an image of an interference pattern reconstructed by irradiating a reference beam and converting the image into m bits. In such an apparatus, a splitter removes least significant j bits from the m-bit data and divides m?j bits of the m-bit data into most significant k bits and remaining m?j?k bits. Thereafter, a compressor converts the most significant k bits into l bits, which is combined with the m?j?k bits to output n bits, wherein l<k and n=l+m?j?k. In this way, by compressing a certain number of most significant bits of the m-bit data and thus relatively increasing the number of the remaining least significant bits of the m-bit data, the BER of final reconstructed image data can be improved.

    Abstract: Surface optical characteristics, alpha-numeric markings and other design features of memory cards, flash drives and similar devices combine to provide the devices with unique outer appearances. In one example, markings are held a distance from a reflective surface such that reflections of the markings off the surface are visible adjacent the markings. In another example, a diffusely reflecting rainbow hologram is combined with such markings or other design features.
