Abstract: 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.

Abstract: 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.

Abstract: An active target has a target face that is backlit by LEDs, where a detection layer behind the target face detects a new projectile hole in the target, such as from a gun or an arrow. The detection layer may be formed of one or more resistive layers, and the detected increase in resistance due to a new projectile hole being created is sensed and correlated to an XY position of the hole. The location of the new hole is transmitted via an RF signal to the shooter's portable device, such as a smartphone, and the shooter sees the location of the hit relative to the target face in real time. The LEDs may be dynamically controlled. The target is disposable and is supported by a support base containing the control electronics and transmitter.

Abstract translation: 主动目标具有由LED背光的目标面，其中目标面后面的检测层检测到目标中的新的射弹孔，例如从枪或箭头。 检测层可以由一个或多个电阻层形成，并且检测到由于所产生的新的抛射孔引起的检测到的电阻增加，并与孔的XY位置相关联。 新孔的位置通过RF信号传送到射手的便携式设备，例如智能手机，并且射手实时看到相对于目标脸部的命中位置。 LED可以动态控制。 目标是一次性的，并由包含控制电子设备和发射器的支撑基座支撑。
