摘要： A method and a system are disclosed for processing a banknote. The method includes providing a banknote having at least one photonically active security feature, the banknote being moved along a conveyance path; illuminating the at least one security feature with light from a stimulus source; identifying a location of the at least one security feature by detecting an emission from the security feature; directing an excitation source at the identified location; illuminating the at least security feature with light from the excitation source; and detecting a further emission from the photonically active security feature in response to the light from the excitation source. Further the process includes the step of analyzing the shape and size of each object within an image during the search phase to determine if the object has the expected physical attributes of the real feature.

摘要： Disclosed are security articles and methods and systems for authenticating security articles through the application if temperature related stimuli. Carefully synthesized nanostructures are formed to exhibit a large number of defect states within the bulk of the nanostructure. The large number of surface defects create a plurality of electron trap states below the conduction band of the composition and/or a plurality of hole states above the valance band such that excitations are induced by small changes in energy at or around kT. In this manner, a security article formed using the synthesized nanostructures produces measurable changes in spectral output based on small changes in temperature at or about room temperature. This allows the security article to be verified at high speeds with low power requirements for induced temperature change.

摘要： A sensor for checking different features of value documents is arranged to carry out a self-test for testing its functionality. Before the sensor carries out its self-test, at least one of the features that is to be checked by the sensor is selected. It is provided in the self-test that the sensor rates a malfunction ascertained in the self-test differently and reacts to the ascertained malfunction differently in dependence on the selected feature. While a malfunction of the sensor has hitherto always led to a failure of the sensor, the sensor, despite ascertained malfunctions, can nevertheless carry out the check of certain features. It is achieved that the number of function failures of the sensor is reduced through the different reactions of the sensor to the ascertained malfunction in dependence on the feature.

摘要： A gain medium is comprised of a multi-phase system wherein: a first phase is an electromagnetic radiation emission phase; a second phase is an electromagnetic radiation scattering phase; and a third phase is a transparent matrix phase. By example, the emission phase may consist of dye molecules, the scattering phase may consist of high contrast particles, and the matrix phase may consist of a solvent such as methanol. In some embodiments of this invention the emission and scattering phases may be the same phase, as when semiconductor particles are employed. A smallest dimension of a body comprised of the gain medium may be less than a scattering length associated with the scattering phase. It is shown that nearly thresholdless laser behavior is observed in strongly scattering optically pumped dye-methanol solutions containing colloidal TiO.sub.2 or Al.sub.2 O.sub.3 ruby nanoparticles. The emission from the high gain colloid exhibits a slope change in the linear input-output characteristics above a critical pump pulse energy. The change in slope is accompanied by a spectral line narrowing with a bichromatic spectrum appearing at high pump energies.

摘要： An improved method of generating a master pattern corresponding to given denomination for use in a discrimination system capable of discriminating among currency bills of different denominations. The master pattern is stored in a memory for subsequent comparison to a pattern generated from a bill under test. The method comprises the steps of generating a plurality of component patterns for a given denomination by scanning a genuine bill of the given denomination and generating a master pattern for the given denomination. The master pattern is derived from an average of the component patterns. The component patterns represent and approximate analog amplitude variations in characteristic information detected from a genuine bill during scanning. Each of the component patterns comprises a plurality of sample values. Each sample value is proportional to the detected characteristic information.
