20150363990 | UNIQUE IDENTIFICATION OF COIN OR OTHER OBJECT - A method of producing an authenticatable article. An overt feature is produced in the article using a fabricating technique which is selected based on a material of the article so as to produce the overt feature having predetermined, reproducible macroscopic characteristics as well as random, non-reproducible microscopic characteristics rendering the article physically unique. The overt feature including the microscopic characteristics are imageable using a predetermined imaging technology to produce an overt feature image. An authentication signature is generated based on the overt feature image and stored in a central database. The overt feature may alternatively be produced in an apparatus or means used to manufacture authenticatable articles such that the overt feature including the random, microscopic characteristics is reproduced in the articles. The overt feature and generated authentication code therefore corresponds to articles manufactured using that apparatus or means. | 12-17-2015 |
20140355864 | METHOD AND APPARATUS FOR AUTHENTICATION OF A COIN OR OTHER MANUFACTURED ITEM - A method includes: capturing an image of a coin, locating an acquisition area of the image using a landmark of the coin, the acquisition area comprising a feature unique to the coin and generating a digital representation of the acquisition area. | 12-04-2014 |
20140205856 | Zincating Aluminum - A method of treating aluminum or aluminum alloy includes providing an aluminum or aluminum alloy substrate; depositing a first zincating layer on the substrate by zincate immersion; stripping off the first zincating layer; depositing a second zincating layer on the substrate by zincate immersion; stripping off the second zincating layer; and depositing a third zincating layer on the substrate by zincate immersion. | 07-24-2014 |
20140120372 | Plating Process to Increase Coin Blank Surface Hardness - A method is for plating metal or alloy blanks. The method includes heating the metal or alloy blanks at a recrystallization temperature sufficient to soften the steel for minting; plating the softened metal or alloy blanks with one or more layers of metal or alloy; and heating the plated blanks at a temperature sufficient to reduce plating stresses but below the recrystallization temperature of the outermost plating layer. | 05-01-2014 |
20120273361 | CONTROL OF ELECTROMAGNETIC SIGNALS OF COINS THROUGH MULTI-PLY PLATING TECHNOLOGY - The present invention relates to novel metallic composites that are useful as coinage materials. These composites are produced through a multi-ply plating process and are designed to overcome difficulties associated with calibrating vending machines that can result in fraud. In one embodiment, the metallic composite comprises a steel core over which nickel and then a non-magnetic metal such as copper, brass or bronze is deposited as a layered pair. The magnetic and non-magnetic metals may also be applied in the reverse order, with the copper, brass or bronze applied directly over the steel and then covered by the nickel. The electromagnetic signature (EMS) of the composite is controlled by defining the thickness of the deposited metal layers. Advantageously, the invention overcomes problems associated when different coins are made from the same alloy and have similar sizes, and therefore cannot be distinguished by vending machines. | 11-01-2012 |
