Patent number: 7357986Abstract: This invention provides security articles comprising fibers, threads and fiber sections (“dots”) possessing multiple verification characteristics. The fibers possess unique and difficulty duplicated combinations of complex cross-sections, components, and multiple luminescent responses. The many verifiable characteristics of the security fibers, threads and dots provide high levels of protection against fraudulent duplication of articles in which they are incorporated. The manifold security features provide means of tailoring specific identity characteristics for specific use and users.Type: GrantFiled: May 4, 2004Date of Patent: April 15, 2008Assignee: Honeywell International Inc.Inventors: Thomas Y-T. Tam, Alfred Siggel, Samir Z. Abdalla, Jiunn-Yow Chen, Thomas Potrawa, Huy X. Nguyen

Patent number: 6649263Abstract: A polyester resin, a method for its preparation, the polyester prepared by the method, a method for manufacturing therefrom at increased productivity a dimensionally stable polyester yarn having a low fray count, and the yarn thereby produced. The polyester resin is prepared from high purity terephthalic acid having a particle size distribution described by a Weibull function with narrow ranges of characteristic size and shape factor. The polyester resin has a low filter-blinding index. The polyester yarn is useful for tires, industrial products and other applications.Type: GrantFiled: November 16, 2001Date of Patent: November 18, 2003Assignee: Honeywell International Inc.Inventors: Thomas Y-T. Tam, Samir Z. Abdalla, James G. Neal, John A. Young, Hong-Jian J. Sha, Hu Zhixuan

Publication number: 20030194578Abstract: Security articles comprising elements such as filaments, fibers, including hollow fibers, and threads and thin transverse sections and chopped versions thereof, wherein such elements are dispersed within the articles. Particle scattering and luminescent technology is employed based on scattering, electronic, magnetic and/or light properties to provide compound physical coloration responsive to various portions of the electromagnetic spectrum, including ultraviolet, ambient and infrared. The coloration effects can be highly stable or dependent on specific switching effects linked to, e.g., thermal exposure or actinic radiation. The security articles result in advanced levels of security to avoid counterfeiting of objects including banknote and currency paper, stock and bond certificates, identification, credit, debit and ATM cards, drivers' licenses and bar codes.Type: ApplicationFiled: December 2, 2002Publication date: October 16, 2003Applicant: Honeywell International, Inc.Inventors: Thomas Y. Tam, Samir Z. Abdalla, Kwok-Wai Lem, Juergen Wieczoreck
