摘要： A security system includes a security article and a corresponding detector. The security article comprises a substrate layer having a top surface and a bottom surface. The substrate layer is composed of an electrically nonconductive material. Deposited on the top surface of the substrate layer is a conductive thin film coating having a predetermined electrical resistance between two spaced apart points. In one embodiment, the conductive thin film coating is comprised of a transparent conductive compound and has a thickness in a range between about 7 nanometers to about 700 nanometers. Printing can be positioned either on top of the substrate layer or on top of the thin film coating. The detector corresponds to the security article and has a light source and a pair of spaced apart probes. The detector contains electrical circuitry configured to energize the light source when an electrical resistance is produced between the probes that corresponds to the predetermined electrical resistance for the security article.

摘要： A security article includes a light transmissive substrate having a first surface and an opposing second surface, with the first surface having an embossed region with an optical diffraction pattern or a holographic image pattern. A color shifting optical coating is formed on the substrate such as on the opposing second surface, with the optical coating providing an observable color shift as the angle of incident light or viewing angle changes. The security article can be used in a variety of applications and products to provide for enhanced security measures such as anticounterfeiting.

摘要： A security article includes a light transmissive substrate having a first surface and an opposing second surface, with the first surface having an optical interference pattern such as a holographic image pattern or an optical diffraction pattern thereon. A color shifting optical coating is formed on the substrate such as on the interference pattern or on the opposing second surface of the substrate, with the optical coating providing an observable color shift as the angle of incident light or viewing angle changes. Various processes can be utilized to form the security article, such as vacuum coating processes, lamination, laser scribing, and laser imaging. The security article can be affixed to a variety of objects through various attachment mechanisms, such as pressure sensitive adhesives or hot stamping processes, to provide for enhanced security measures such as anticounterfeiting.

摘要： A common Baker Clamp includes diodes having predetermined reverse-recovery times for responding to a signal having a high frequency on the order of 100 kHz. A pair of anti-parallel diodes coupled between an input terminal and a first output terminal are each characterized by a reverse-recovery time on the order of 2.mu.s. A third diode is coupled between the input terminal and a second output terminal and is characterized by a reverse-recovery time on the order of 200 ns.
