Publication number: 20180357455Abstract: In one embodiment, a printed security mark comprises a random arrangement of printed LEDs and a wavelength conversion layer. During fabrication of the mark, the LEDs are energized, and the resulting dot pattern is converted into a unique digital first code and stored in a database. The emitted spectrum vs. intensity and persistence of the wavelength conversion layer is also encoded in the first code. The mark may be on a credit card, casino chip, banknote, passport, etc. to be authenticated. For authenticating the mark, the LEDs are energized and the dot pattern, spectrum vs. intensity, and persistence are converted into a code and compared to the first code stored in the database. If there is a match, the mark is authenticated.Type: ApplicationFiled: June 13, 2018Publication date: December 13, 2018Inventors: Steven B. Roach, Richard A. Blanchard, Eric Kahrs, Larry Todd Biggs, Chye Kiat Ang, Mark D. Lowenthal, William J. Ray

Publication number: 20180357522Abstract: In one embodiment, a printed LED area comprises a random arrangement of printed LEDs and a wavelength conversion layer. The LED area is embedded in an object to be authenticated, such as a credit card or a casino chip. The object may include a light guide for enabling the generated light to be emitted from any portion of the object. In one embodiment, when the LEDs are energized during authentication of the object, the existence of light emitted by the object is sufficient authentication and/or provides feedback to the user that the object is being detected. For added security, the emitted spectrum vs. intensity and persistence of the wavelength conversion layer is detected and encoded in a first code, then compared to valid codes stored in the database. If there is a match, the object is authenticated.Type: ApplicationFiled: June 13, 2018Publication date: December 13, 2018Inventors: Steven B. Roach, Richard A. Blanchard, Eric Kahrs, Larry Todd Biggs, Chye Kiat Ang, Mark D. Lowenthal, William J. Ray

Publication number: 20170018049Abstract: On a flexible substrate is printed, LEDs, a battery, a flasher, and an actuator. The actuator may be a photo-switch that causes the battery and flasher to periodically energize the LEDs when a sufficient ambient light impinges on the actuator. The substrate may be an insert in a transparent package containing a product, such as a razor. When the package is in the front of a display in a store, the ambient light causes the LEDs to flash, such as every 10-30 seconds to attract consumers to the product. The substrate may also form part of the outer surface of the package. The flasher may simply flash the LEDs or create a dynamic display by energizing different groups of the LEDs at different times.Type: ApplicationFiled: July 16, 2015Publication date: January 19, 2017Inventors: Alexander S.
